Private Sector Funding Options for Water Infrastructure

4 WATERWORLD WWW.WATERWORLD.COM SEPTEMBER 2012

In a move that was more theatre than

substance, Rep. Earl Blumenauer (D-

Ore.) introduced legislation to establish

a federal trust fund for investments in

clean water infrastructure – on the same

day Congress began its annual summer

break. Given the lack of action by Con-

gress in an election year, it is unlikely to

move forward and will die a quiet death

when this session of Congress adjourns.

Still, it was a nice gesture and high-

lights the growing need for alternative

funding sources for water infrastructure.

It has been estimated that such as trust

fund could provide $9 billion annually,

most of that going to support the Clean

Water State Revolving Fund program.

Several methods for fi nancing water

infrastructure investment have been

considered over the past few years,

including an infrastructure bank and an

expanded SRF program. Most, if not

all, called for a signifi cant amount of

federal funding, which is a tough sell

given the soaring federal defi cit.

I recently read an interesting white

paper developed by American Water

that focused on boosting private sector

funding for the municipal water indus-

try. As the largest investor-owned U.S.

water and wastewater utility company,

the company clearly has a vested inter-

est in water infrastructure fi nance.

According to the paper, one key solu-

tion is attracting additional private capital

from investor-owned companies like

American Water, as well as private capital

that is already in infrastructure funds,

pension funds, and other funds seeking

the long-term, reliable investments that

water utility systems can offer.

Top on its list was for Congress to ex-

tend the current dividend tax and capital

gains tax rates. Without action by Con-

gress, the tax rates on dividends and capi-

tal gains are set to increase signifi cantly on

January 1, 2013. Those increases could

limit investment and hurt companies like

American Water that pay dividends and

rely on continued investor growth to

provide access to low cost capital.

The company would also like to see

an end to what it called “punitive” IRS

regulations for private water transac-

tions. Current IRS regulations impose

a signifi cant fi nancial penalty on mu-

nicipalities who sell or lease their water

system to a private company.

One legislative measure that many

thought would make its way through

Congress this year was the Sustainable

Water Infrastructure Investment Act,

H.R. 1802, which would have removed

water projects from the state volume

caps for Private Activity Bonds. Ameri-

can Water believes that removing the

bond cap would spur increased private

investment in water and wastewater

systems throughout the country.

Some believe that lifting the cap for

water projects could generate at least $2

billion in new investment each of the fi rst

few years and grow to several times that

as the market opens up. Other major in-

frastructure components already exempt

from existing caps include airports, high-

speed rail and solid waste disposal.

Ultimately charging full cost pricing

and focusing on effi ciency may be the

only real answer for public water agen-

cies, but encouraging private investment

may be one alternative to con-

sider for cash-strapped utilities.

To read the American Wa-

ter white paper on Financing

Solutions for Water Infra-

structure Investment, look

under the white paper tab in

the press resources

section of www.

probe also reduces maintenance—no

hydration, conditioning, or spe-

cial storage is required. The use of

membranes and fi lling solutions are

eliminated. The RDO PRO Probe’s

patented signal processing design re-

sponds quickly to oxygen and temper-

ature changes and delivers consistent,

reproducible results.In-Situ

Leaks

eventually

tell you where

they are...

but can you

afford to wait?

Leak DetectionDon’t wait for a main break to cause health anxiety and disruptions

for customers. Find leaks before they erupt and become costly,

water-wasting emergencies.

Aclara’s STAR® ZoneScan leak-detection solution locates leaks

while they are still underground. Jointly developed by Aclara and

Zurich-based Gutermann International, the STAR ZoneScan

employs data loggers placed on gate or hydrant valves to “listen”

for sound waves generated by leaks along the main. The loggers

send this data to the utility over the industry-leading Aclara STAR®

Network. It is then correlated to pinpoint potential leaks to within a

few feet.

Two-Way Fixed-Network AMIThe STAR ZoneScan is just one example of how Aclara’s two-way

STAR Network system can extend beyond traditional meter

reading. The flexible and scalable system transmits hourly data

from meters, helping utilities with daily water accountability and

encouraging practical water conservation. For more information,

Groups Seek Guidelines to Protect Groundwater from FrackingBy Patrick Crow, Washington Correspondent -----------------------------------------------------------------------------------------------------------------------------------------------

Three water groups have proposed

guidelines to protect groundwater

from the hydraulic fracturing of oil

and gas wells.

The American Water Works Associa-

tion, the Association of Metropolitan

Water Agencies and the National Asso-

ciation of Water Companies said oil and

gas developments must protect ground

water and surface water resources.

They said the Environmental

Protection Agency (EPA) should

use existing Safe Drinking Water Act

(SDWA) authority to regulate oil and

gas well construction and operation

through the Underground Injection

Control (UIC) program.

Also, Congress should remove

statutory barriers impeding federal

regulation and oversight of oil and

gas wells under the UIC program,

particularly involving fracturing.

They said EPA should also use its

Clean Water Act (CWA) authority to

regulate discharges to surface water

bodies from oil and gas operations,

including the expedited preparation of

effl uent guidelines under the CWA’s

National Pollution Discharge Elimina-

tion System program.

Finally, Congress should provide

adequate resources to EPA and

partner federal agencies necessary to

support timely research and regulatory

oversight under the SDWA, CWA and

other appropriate statutes.

The water groups said that the

impact of drilling and completion

activities on ground water and surface

water supplies should be actively

monitored, and the federal govern-

ment should ensure the that hydraulic

fracturing activities are reported to

local governments.

“Notifi cation is critical to addressing

community impacts, including mitigat-

ing potential implications for drinking

water supplies. Drinking water systems

need information about the chemicals

to be injected in conjunction with

hydraulic fracturing activities, as well as

the amount and sources of water to be

used,” they said.

Pennsylvania Water Study

The U.S. Geological Survey and

the Pennsylvania Department of

Environmental Protection detected

low concentrations of contaminants --

including pharmaceuticals, hormones

and organic wastewater compounds

-- in rivers and streams throughout

Pennsylvania during a four year study.

“These fi ndings are intended to help

wastewater and drinking water manag-

ers to make decisions about water treat-

ment options given the ever increasing

number of new compounds that come

into use and end up in the state’s water-

ways each year,” said Andrew Reif, the

USGS scientist who led the study.

The 10 most frequently detected

compounds represented a wide variety

of uses, but all were derived from

human sources. None of the most

commonly detected compounds were

typically used in agricultural opera-

tions and most entered the stream en-

vironment from municipal wastewater

treatment facilities or septic systems.

Throughout the state, the most

commonly found compounds in

stream water were caffeine; acet-

aminophen; carbamazepine – a seizure

medication; sulfamethoxazole and

trimethoprim – antibiotics; and the

hormone estrone. Other commonly

detected compounds include the

antihistamine diphenhydramine; the

antibiotics azithromycin, erythromy-

cin, and ofl oxacin; the fl ame retardant

tri(dichloroisopropyl) phosphate; and

the insecticide DEET.

In the heavily agricultural south-

central part of the state, the most

commonly detected contaminants

in stream water samples were car-

bamazepine, sulfamethoxazole, and

tri(dichloroisopropyl) phosphate–a

fl ame retardant. The contaminants

most commonly detected in sediment

samples were the antibiotics ofl oxacin

and trimethoprim, estrone, and the

polycyclic aromatic hydrocarbons

benzo[a]pyrene, fl uoranthene, phen-

anthrene, and pyrene.

Tests of waters downstream from

wastewater discharge sites showed

higher concentrations and numbers

of compounds detected than from

tests of water upstream of those sites,

indicating that wastewater discharges

are a source of contaminants.

The concentrations of individual

contaminants were generally low, less

than 50 nanograms per liter, equal

to less than one drop of water in an

Olympic-sized swimming pool. Con-

centrations and compounds found near

some of the state’s sources of drinking

water were consistent with compounds

and concentrations found in other

studies throughout the nation.

The report said that when used for

drinking water, the amounts of many

of the contaminants can be eliminated

or reduced by conventional or ad-

vanced treatments at water treatment

facilities. It noted that drinking-water

standards have not been established

for the individual compounds or for

the mixtures found, so the potential

human-health risk of chemicals that

may be present in drinking water after

treatment is unknown.

Water Supply Reservoirs

American Rivers has urged South-

eastern U.S. communities to carefully

evaluate the construction of water

supply reservoirs.

The environmental group said

many local governments throughout

Georgia, the Carolinas and neighbor-

ing states are considering constructing

water supply reservoirs. Collectively,

current reservoir proposals in Georgia

could total $10 billion.

“Building a water supply reservoir

is an incredibly expensive undertaking

that carries tremendous risk and sad-

dles communities with debt, with no

guarantee they’ll receive the hoped-for

water,” said Jenny Hoffner, director of

water supply for American Rivers.

The report said reservoirs are very

expensive, their price tags tend to

increase, their fi nancing plans often

rely on infl ated population growth

projections, they depend on uncer-

tain rainfall, and competing demands

for river water make water supplies

problematic.

For example, American Rivers said

the Hickory Log Creek Reservoir

for Canton, GA, quintupled in price

during its development and the debt

burden has hurt the town’s ability to

address basic community needs.

The group said that rather than

proposing new reservoirs, government

leaders should fi rst optimize exist-

ing water infrastructure. It said they

should plan for water use to decrease

as a community grows and pursue

fl exible water supply solutions.

In other Washington developments:

-- Rep. Earl Blumenauer (D-Ore.) has

introduced a bill to raise $9 billion

per year for the federal Clean Water

state revolving loan fund, fi nanced

by taxes on consumer liquids

containers, drugs, and products dis-

posed of through sewer systems.

-- Four senators have urged EPA

not to require “inherently safer

technology” practices at facilities,

including water utilities, which use

large amounts of certain hazardous

chemicals. They were James Inhofe

(R-Okla.), Susan Collins (R-Maine),

David Vitter (R-La.) and Mary

Landrieu (D-La.).

-- Sen. Jeff Bingaman (D-N.M.) has

introduced a bill to provide federal

tax credits of up to 30% for projects

that increase water effi ciency at

manufacturing plants. They would

include water reuse, recycling, and

effi ciency investments related to

process, sanitary, and cooling water.

-- EPA said Chattanooga, TN, will pay

a $476,400 penalty and rehabili-

tate its sewer collection system to

eliminate overfl ows of untreated

sewage. It also agreed to restore

and stabilize the banks of a South

Chickamauga Creek tributary at a

cost of $800,000. WW

Selecting the best coupling type

for an application can have a positive

impact on pump, driver, and/or cou-

pling reliability and maintenance costs.

Radial and/or axial loads that are

transmitted to the pump and/or mo-

tor bearings (through the coupling)

will reduce the life of these bearings.

Further, any

transmitted

vibration will

also short

the life of the

pump me-

chanical seal.

The pri-

mary function

of a coupling

is to trans-

mit rotary

motion and

torque from

one piece of

equipment to

another. Couplings may also perform

other (secondary) functions, such

as accommodating misalignment

between shafts, transmitting (or

not transmitting) axial thrust loads

and vibration from one machine to

another, permitting axial adjustment

of the shafts to compensate for ma-

chinery wear, and maintaining precise

alignment between connected shafts.

Another secondary function pro-

vided on many pump couplings is a

separate “spacer” section that allows

the driver and driven shaft ends to be

positioned a specifi ed distance apart.

The coupling spacer on horizontal

pumps can then be removed to allow

suffi cient axial clearance to replace a

mechanical seal without moving the

pump or motor, or to allow room for

the pump “back-pull-out” element

to be replaced without moving the

motor. Also, since allowable shaft

misalignment is normally expressed

in fractions of an angle (in degrees) a

longer spacer will accommodate more

parallel shaft offset than a shorter

spacer or couplings without spacers.

Most couplings can be provided in

spacer or non-spacer confi gurations.

Couplings can be divided into two

primary groups, rigid and fl exible.

Rigid couplings are used to connect

machinery shafts, where it is desir-

able to maintain the shafts in precise

alignment, transmit torque and axial

thrust (if desired). Rigid couplings are

common on vertical turbine pumps as

well as some short set pumps. Flex-

ible couplings accomplish the primary

function of any coupling, transmitting

the driving torque between the driver

and driven machine. In addition,

they perform a secondary function

of accommodating a set amount of

misalignment between the driving and

driven shafts. Most horizontal, base-

plate mounted (long-coupled) pumps

use fl exible couplings.

The following technical information

is normally required when selecting a

coupling:

• Horsepower to be transmitted

• Operating speed

• Angular Misalignment

• Offset misalignment

• Axial travel

• Limitation on coupling generated

forces

• Ambient temperature

• Space limitations

Rigid Couplings

Rigid couplings are found in certain

short set, vertical-in-line, and verti-

cal turbine pumps applications. Since

these couplings do not compensate for

any misalignment between the pump

and motor shaft ends, failure to ensure

precise alignment of the connecting

shafts will result in increased vibration,

bearing wear, and shortened mechani-

cal seal life.

Flexible Couplings

Flexible couplings, which are used

for most horizontal pump applica-

tions, may be separated into three

basic types, mechanically fl exible,

material-fl exible, and non-contact

magnetic. Mechanically fl exible

couplings compensate for misalign-

ment between two connected shafts

by means of clearances incorporated in

the design of the coupling. Material-

fl exible couplings rely on fl exing of

the coupling element to compensate

for shaft misalignment. Modern non-

contact magnetic couplings rely on

rare earth permanent magnets which

induce current fl ow in the mating

electro magnets. They are separated

by an air gap.

Mechanically Flexible Couplings

Mechanically fl exible couplings

compensate for misalignment between

the connected shafts by means of clear-

ances incorporated in the design of the

coupling. Gear couplings are probably

the most frequently used mechanically

fl exible coupling confi guration. They

are “power-dense”, meaning that they

are capable of transmitting high torque

at high speeds in a compact size. Axial

force and moment transmission can be

quite signifi cant with gear couplings.

The axial force must be absorbed by

the thrust bearings in the driver and

driven machines. Also, these couplings

must be periodically lubricated with

coupling specifi c grease, which adds

to the maintenance cost. Further, the

gear teeth are prone to wear over time.

Material-Flexible Couplings

These couplings rely on fl exing of

one or more coupling elements to

compensate for shaft misalignment.

The fl exing element may be of any

suitable material (metal, elastomer, or

plastic), which has suffi cient resistance

to fatigue failure to provide acceptable

life. Material-fl exible couplings do not

require periodic lubrication, but the

fl exing action can generate excessive

heat (a potential problem with elas-

tomer or plastic couplings), and/or

can cause fatigue (a potential problem

with metals), if loads or misalign-

ment exceed defi ned limits. This will

shorten the life of these couplings.

The advantages of material-fl exi-

ble, non-lubricated couplings (over

mechanically-fl exible couplings) are:

1. No down time for lubrication.

2. Generally transmit low, known

thrust forces.

3. They can be designed for infi nite life.

4. Except for the rubber tire-type cou-

plings, maintaining balance is easier

than for gear couplings.

Metallic Flexible Material

Couplings

Metal-disc (or disc-pack) couplings

are the predominant type used in pro-

cess plants throughout the industrial-

ized world. They use thin, contoured,

high-strength alloy steel laminated

sheet-metal discs alternately bolted to

the driving and driven hub members.

There are numerous confi guration

variations of this coupling. Properly

selected and installed, disc pack cou-

plings with captured center members

are generally the most cost-effective

choice.

Another example of an all-metal

material-fl exible coupling is the

contoured diaphragm coupling. This

coupling is similar in function to the

metal-disc coupling in that the single

or twin disc assemblies fl ex to ac-

commodate misalignment. They are

primarily used for large pumps.

Metallic fl exible material couplings

have the following advantages:

• No downtime for lubrication

• Transmit low, known, thrust forces

• Can be designed for infi nite life

• Better balance can be maintained

• Torsionally Stiff

• Good high temperature capability

• High torque

• High speed

• Zero backlash

Metallic fl exible material coupling

limitations:

• Fatigue potential when misalign-

ment exceeds coupling limits

• Most need careful alignment

• Usually cannot damp vibration

Elastomer Material Flexible

Couplings

Material-fl exible couplings employ-

ing elastomeric materials are numer-

ous. Elastomers generally do not have

a well-defi ned fatigue limit. However,

most elastomers do suffer some form

of degradation from heat and require

de-rating at elevated temperatures.

Heat develops in the material when

the coupling fl exes, and claims that

they will operate at severe misalign-

ments are often very misleading. Any-

thing other than moderate misalign-

ment will severely limit coupling life.

Elastomeric fl exible material couplings

advantages are as follows:

• Generally do not have defi ned

fatigue limits

• Torsionally soft / good vibration

damping

• No lubrication or maintenance

• Less expensive than metallic couplings

• Lower reactionary loads on bearings

• More misalignment allowed than

metallic types

Elastomeric fl exible material coupling

limitations:

• Sensitive to chemicals / high tem-

peratures

• Larger outside diameters than me-

tallic couplings

• Diffi cult to balance as an assembly

• Some types have low overload

torque capacity

Magnetic Couplings

The same basic coupling used for

the “Adjustable Speed Permanent

Magnet Drives” spelled out in last

month’s Pump Tips Column, can also

be used in a simplifi ed version as a

constant speed pump coupling, with

some distinct advantages. The biggest

advantage is that the air gap allows the

coupling to tolerate the highest shaft

misalignment of any coupling type, to

the point that laser alignment of the

pump and motor shaft is not neces-

sary. Also, it will not transmit vibra-

tion and/or forces between the pump

and motor. This can increase bearing

and mechanical seal life in pumps and

bearing life in motors.

Advantages of magnetic couplings:

• Low maintenance, does not require

periodic lubrication

• Tolerates gross parallel and angular

misalignment.

• Eliminates vibration transfer be-

tween motor and pump

• Increases seal life

• Permits shock loading

• Overload torque protection, self-

resetting

• Cushioned starts and stops

Limitations of magnetic couplings:

• High initial cost

• Couplings will experience a 1% - 3%

slip (slight speed reduction)

• Heat sensitive:

– Induction current adds heat to

driven portion of coupling

– Excessive heat can weaken perma-

nent magnet strength.

To protect area streams and rivers,

the City of Detroit began building a

network of combined sewer overfl ow

basins 25 years ago. Today, the de-

partment operates eight such basins,

strategically sited in places where

storm runoff would otherwise reach

area rivers. By capturing and sub-

stantially treating the stormwater, the

basins play a major role in protecting

the surrounding watersheds, and the

people and wildlife living there.

In just the fi rst three months of

2011, for example, the basins col-

lected more than 5 billion gallons

of runoff that would have otherwise

escaped into waterways. While a third

was pumped to the main plant for

treatment, the rest of that water was

treated in the basins.

Each combined sewer overfl ow facility

differs somewhat in size and design, but

all basically apply the same treatment

process: retaining the overfl ow, mechani-

cally screening out solids, and disinfect-

ing the water with sodium hypochlorite

(bleach). Basins also have equipment

that operators use to monitor fl ow rate

and volume, collect samples, remove

residual water from the basins, and clean

them after a wet-weather event.

Despite their similar functions, the

basins’ process control instruments

vary widely. That’s partly because

the basins were constructed over

the course of the last three decades

at a time when automated control

technology was quickly evolving. The

comparatively slow pace of public

works projects was also an issue. From

concept to commissioning, each basin

required several years to complete be-

cause of strict municipal codes requir-

ing public planning, open bidding and

offi cial oversight. Meanwhile, federal

and state water quality standards were

becoming more stringent, adding

another layer of complexity.

“Through the years, we’ve had to

update the process control systems at

various basins to comply with chang-

ing regulations,” said Anil Gosine,

Process Control System Administrator

for the Detroit Water and Sewerage

Department (DWSD). The result is a

“myriad of different process control

systems at different locations. At one

basin, we have process control equip-

ment from four different vendors.”

Such a hodge-podge of legacy

equipment makes integration diffi cult

or impossible.

“The lack of a standardized plat-

form also hampers troubleshooting

and maintenance,” Gosine said. “In-

ventory is another problem, because

we need to keep so many different

spare parts on hand.”

In 2004, DWSD hired a consultant

to design new, more effective and ef-

fi cient control systems for two existing

Combined Sewer Overfl ow Facilities.

DWSD engineers specifi ed Rockwell

Automation as the vendor for the

process control systems after per-

forming a life cycle cost analysis.

The new system leverages the

company’s PlantPAx™ Process

Automation System, which is an

integrated control and information

system. System integrator Process

Control & Instrumentation (PCI),

LLC, was awarded the contract for

replacement of non-functional control

system instrumentation at two DWSD

CSO Basins. PCI, a control engineer-

ing fi rm with an offi ce in Detroit,

worked with DWSD on other recent

projects, giving PCI engineers a good

understanding of the DWSD overall

SCADA system.

But PCI faced a dilemma when it re-

ceived the contract to retool the basins.

The company had strategically offered

the lowest bid to win the project with

DWSD, as well as partner with Rockwell

Automation for the fi rst time. However,

PCI engineers were concerned that the

total cost of replacing the obsolete con-

trol systems would exceed the agreed-

upon contract amount.

Rockwell engineers recommended

a solution that kept the project within

budget – its PlantPAx Process Library

and Water/Wastewater Accelera-

tor toolkit. The process library is a

software application for the Logix

Control Platform that includes an

array of pre-engineered code that can

be used in various applications. It also

incorporates custom faceplates based

on specifi c plant roles, information-

laden icons and full documentation.

The Water/Wastewater Accelerator

toolkit customizes those elements to

signifi cantly reduce the time required

to design, install, operate and main-

tain a wastewater project. The toolkit

contains confi gured fi les, selection

tools and examples of how to connect

the Allen-Bradley® ControlLogix®

controller to the facility’s human

machine interface (HMI) hardware

and other devices over EtherNet/IP™

and DeviceNet™ networks. The tool-

kit also provides system architecture

drawings, basic status, control and di-

agnostic logic, as well as faceplates for

FactoryTalk® View Site Edition HMI

software from Rockwell Automation

used in the new Detroit basins.

“In the past, we’d have to program

the HMI separately from the con-

troller and then link them together.

The toolkit comes with 80 percent of

the necessary code, predefi ned and

factory-tested. So you’re free to focus

on customizing the machine control

for the customer,” said PCI’s controls

CSO Facility Replaces Obsolete Control SystemsThe new system provides integrated data from the two CSO basins, helping improve diagnostics and allowing for more preventive and predictable maintenance.

engineer on the DWSD basins project.

The Rockwell team helped train

PCI’s engineers on how to use the

process library and the accelerator

toolkit to custom confi gure the system

for the Detroit basins.

“We needed to modify the toolkit

to make the process data presentation

familiar to DWSD operating folks,”

the PCI engineer said. “Some graphic

faceplate elements didn’t align with

DWSD’s color and naming conven-

tions. For instance, they were used

to seeing a red light when a piece of

equipment was turned on, instead of

the green light built into the process

library. So we made that change and

others that created a special standard

toolkit just for Detroit.”

Results

The PCI engineer

estimated that the process

library and toolkit cut his

work in half for both basins,

saving around $120,000 in

programming and systems-

integration time. Another $90,000 was

saved in factory-acceptance testing and

startup/commissioning.

“Programming the fi rst motor took

two hours, but after that I just had

to copy and paste the code,” said the

engineer, who now is working on

his fourth project using the process

library and toolkit. “The cooperation

I’ve gotten from Rockwell Automa-

tion has been amazing. I had the op-

portunity to interface with the original

programmer of the toolkit to make

the changes as needed.”

The lead engineer on the toolkit

was also among the Rockwell experts

who traveled to Detroit to demon-

strate the advantages of the system,

and later returned to conduct project

workshops for city engineers and

wastewater operators.

DWSD offi cials estimate the new

tools from Rockwell provided a 50

percent reduction in design time,

contract oversight, and post-contract

documentation and support.

“There’s a much shorter learning

curve for the operators with the Plant-

PAx system,” said Gosine, who helped

oversee the project for DWSD. “We

also have access to a lot more data

in an integrated format at these two

basins. That has really improved the

diagnostics, allowing more preventive

and predictable maintenance.” WW

WEFTEC EXHIBITORS


New Orleans to Host WEFTEC 2012WEFTEC 2012, the annual event hosted by the Water Environment Federation, will take place Sept. 30 through Oct. 3 in New Orleans, LA. The program in-

cludes 130 technical sessions, 24 workshops and eight local facility tours, and is expected to draw thousands of water quality professionals and exhibitors from

around the world. To date, nearly 900 companies have already reserved over 290,000 net square feet of fl oor space at the New Orleans Convention Center.

For more information on the event, and details on the individual paper presentations, visit www.weftec.org.

Nutrient removal and recovery

will be among the important topics

discussed at this year’s WEFTEC con-

ference, set for Sept. 30 through Oct.

3 in New Orleans. Across the coun-

try, and especially in key watersheds,

utilities are being challenged to meet

increasingly stringent nutrient limits

for wastewater discharges. At the same

time, there is a growing interest in

recovering nutrients from wastewater,

especially phosphorus.

Ana Pena- Tijerina from the City of

Fort Worth, TX, and Rajendra Bhatta-

rai from the city of Austin, will discuss

the challenges they’ve faced in trying

to help develop nutrient criteria for

the state of Texas. Their paper, “The

Texas Two-Step: Developing the Nu-

meric Nutrient Criteria for the Second

Largest State in the U.S,” will discuss

the challenges, and frustration, they

have experienced as they’ve worked

through this process.

Bhattarai said “a dance” has been

going on between USEPA and the

Texas Commission on Environmental

Quality (TCEQ),

with EPA insist-

ing on strict

numeric criteria

for total nitrogen

and total phos-

phorus, while

Texas has put

forward surro-

gate criteria as an alternative. In 2010,

TECQ submitted criteria for 75 major

reservoirs in the state but they have

yet to be approved by EPA.

“We realize that what we are seeing

here in Texas is not really any different

from what other states are seeing or fac-

ing. The challenges are the same,” said

Pena- Tijerina. “The reason for this pa-

per was to make the point that we have a

common problem here. The challenges

are basically the same, and maybe we can

work together to solve these issues.”

One major challenge has been the

low numeric levels sought by EPA,

which would be diffi cult and expen-

sive to achieve with current technolo-

gies, Pena- Tijerina said.

“Most of the wastewater treat-

ment plants here in Texas are smaller

than 10 mgd, so having to install the

technologies needed to achieve those

very low numeric criteria is just not

possible,” she said.

Stephanie Sansom, a supervising

engineer at MWH, will present a

paper that highlights the challenges

faced by utilities trying to meet low

numeric criteria. Her paper, “TN and

TP - How Low is Low and How Do

We Get There?” highlights a series of

treatment plant projects designed to

tackle low nutrient levels.

In one example pilot project in

Florida, the treatment facility faced

two different phosphorus limits --

0.27 mg/l for reuse in wetlands appli-

cations and a very tough 0.005 mg/l

for discharge to Class 3 Outstanding

Florida Waters.

The pilot project used MBR, chem-

ical addition for additional phospho-

rus precipitation, followed by reverse

osmosis and then advanced oxidation

processes, Sansom said.

“The point of that plant wasn’t to

look at the various technologies, it

was really seeing if we could actu-

ally get to that (0.005 mg/l) level by

throwing everything at it,” Sansom

said. “We could achieve the .27 level,

but we could not achieve the .005.

We came close. We

got down to point

.007 on one or two

samples.”

The facilities in

her study were all

discharging to sensi-

tive water bodies

and had limits that

went beyond those imposed by US

EPA, she said.

“We found that MBR systems

can remove dissolved phosphorus

after chemical addition. Ultra fi ltra-

tion have been successful at rejecting

particulate sections of phosphorus

and that can be enhanced by chemical

addition, and then reverse osmosis has

various rejections,” Sansom said.

Still, few treatment facilities would

be willing or necessarily able to install

an RO system to achieve extremely

low nutrient levels, she said.

“For every additional point or ad-

ditional .5 of phosphorus or nitrogen,

you have to consider how much ad-

ditional energy does it cost, how much

additional chemicals,” Sansom said.

“Obviously, there is a limit not only on

technology but what treatment plants

are willing to spend on capital and op-

erational expenditures. And you have to

ask, at what point does the technology

or operational requirements outweigh

the sustainability of the plant?”

Nutrient Recovery

While utilities are struggling to

meet – or prepare for – tighter nutri-

ent limits, there is a growing interest

in resource recovery in the wastewa-

ter treatment industry. Recovering

nutrients for reuse can help preserve

resources and also potentially help

offset the cost of treatment, said Dr.

James Barnard of Black & Veatch.

Barnard will present a paper en-

titled “State-of-the-art Recovery Of

Phosphorus From Wastewater.” The

paper will examine both biological and

chemical recovery system and look at

work underway in the US and abroad.

Barnard is recognized for his devel-

opment of biological nutrient removal

processes. He said phosphorus is a

limited resource and will grow in value

in the years ahead. While chemical pre-

cipitation can produce a viable fertilizer

product, he prefers biological processes

for recovering phosphorus. He said the

two processes can be used in combina-

tion to help increase recovery as utilities

strive to meet lower discharge limits.

As more facilities turn to biological

phosphorus removal, a large fraction

of the nutrient becomes concentrated

Stormwater runoff has been called

the single most common cause of

pollution in our nation’s waterways,

carrying a variety of pollutants, such as

sediment, bacteria, organic nutrients,

and hydrocarbons to our watersheds

and degrading water quality. But

controlling and managing a non-point

source of pollution isn’t easy — fl ows

can be unpredictable, pollutants are

variable, and regulatory requirements

can be confusing. Couple that with

very limited funding and you’ve got a

perfect storm indeed.

This year at WEFTEC, stormwa-

ter will be covered like never before.

“Compared to previous years, there’s

been an overall increase in the topic

[of stormwater] and the program

refl ects that,” said WEF’s Stormwater

Program and Policy Manager Seth

Brown. Nearly 40 papers across seven

sessions will delve specifi cally into

stormwater and green infrastructure

topics, exploring such themes as estab-

lishing stormwater utilities; sustain-

able stormwater infrastructure design;

managing urban stormwater with

trees; and using computer modeling

to help manage the impact of rain

events on watersheds.

This is the second year WEFTEC

has planned a dedicated stormwater

track, something Brown said is a refl ec-

tion of the maturation of WEFTEC’s

programming. “In the past, storm-

water topics focused primarily on wet

weather issues like CSOs,” he said.

“While that’s still part of what we do,

we are starting to diversify and talk

about things like rainwater harvest-

ing, sediment and erosion control, and

fi nancing options for stormwater.”

In addition to the traditional Tech-

nical Sessions, WEFTEC will offer

for the fi rst time this year a number

of Featured Sessions, which follow a

somewhat different format — includ-

Spotlighting Stormwater at WEFTEC.12 By Angela Godwin, Chief Editor

The lines between stormwater,

drinking water, and wastewater are

quickly fading as we begin to embrace

the concept of holistic water manage-

ment, the idea that all of our water

resources are not only interconnected

but interdependent. It’s worth noting

that a new session at WEFTEC this

year will bring water leaders from sev-

eral different sectors together to share

their perspectives on how to work

smarter — not harder — to manage

water and meet our quality and quan-

tity needs. On Monday, October 1,

10:30 AM - 12:00 PM, join WEF’s

Executive Director Jeff Eger and fi ve

distinguished speakers for insights

into their urban water management

visions and strategies for attaining

it. Speakers include: DC Water’s

George Hawkins; American Water’s

Jeff Sterba; Xylem’s Gretchen Mc-

Clain; University of South Florida’s

Kala Vairavamoorthy; and U.S. EPA

Administrator, the Honorable Lisa

Jackson (invited).

ing a lively panel discussion — and

are put together and led by leading

industry experts.

One of those Featured Session is

titled “EPA’s Stormwater Effl uent

Limitation Guidelines: A Moving and

Disappearing Target.” Three speakers

from the International Erosion Control

association will deliver presentations,

question each other, and then take

questions from the audience. They’ll

cover some ELG history, treatment

technologies, EPA activities and re-

search on the subject, and fi nally offer

their predictions on where things are

headed.

“It’s focusing on erosion and sedi-

ment control guidelines for construc-

tions sites,” said Brown. “That’s a

new area for WEF and one that I’m

excited about.”

It’s Not Easy Being Green...

Or Is It?

Communities across the country are

doing some amazing things when it

comes to managing stormwater with

green infrastructure. WEFTEC’s ‘Big

Cities Turn Stormwater Green’ session

will highlight a few of these: Orlando,

Philadelphia, and New York City, to

name a few. One presentation will also

discuss how alternative green infrastruc-

ture can help cities save big dollars.

As water quality regulations grow

more stringent, it’s becoming clear

that traditional gray infrastructure

isn’t enough. In the ‘Gray, Green,

and Integrated Stormwater Design’

session, six presentations will outline

how municipalities were able to suc-

cessfully combine planning, outreach,

engineering and management to cre-

ate innovative designs that utilized the

best of gray and green infrastructure

to manage runoff.

Trees can bring some tremendous

benefi ts to an urban environment:

they’re not just aesthetically pleasing

but also help conserve water, minimize

erosion, support wildlife, reduce air

pollution, and mitigate greenhouse gas

effect. But urban forests are not with-

out their challenges. Industry experts in

WEFTEC’s “Urban Trees for Storm-

water Management” session will discuss

these issues and strategies for reducing

the impact of trees on urban infrastruc-

ture and improving the success rate and

overall health of urban trees.

“Cities are facing long term control

plans and consent decrees and they’re

seeing that green infrastructure can be

a cost-effective way to deal with these

issues,” said Brown. At the same time,

EPA is opening the door to green so-

lutions through their new integrated

planning approach.

“There’s more interest, even out-

side the regulatory environment, to

use a technology or an approach that

can be — and has often been shown

to be — more cost-effective that just

gray solutions,” said Brown.

There are also a number of side

benefi ts to green infrastructure:

public health improvement, aesthetic

value, and economic revitalization of

WEFTEC attendees are sure to no-

“We recognize the value and inter-

est in stormwater across the water

sector,” said Brown. “These integrated

water management issues aren’t just

rhetoric, they are real issues. We hear

you, we’re addressing it, and we’re

here to meet the rising challenge of

stormwater. Look for big things from

us.” WW


Before LaserFlow, non-contact sensors only measured surface

velocity. Now, this non-contact sensor penetrates the water with

laser technology to measure velocity at multiple subsurface points.

Simplify your collection system monitoring with these

advantages:

��No confi ned space entry with mounting hardware in place

��Multipoint subsurface velocity measurement ensures

quality reading without manual profi ling

��Advanced submerged fl ow option measures in-

pipe velocity (not single-point velocity) during

surcharged conditions

��Th is meter does all the work so you don’t have to.

The Town of Sturbridge in Worces-

ter County, MA, operates a publicly

owned treatment works that serves

more than 9,000 residents and lo-

cal businesses. The treatment plant

has experienced

steadily increasing

fl ows over the last

25 years due to

signifi cant popula-

tion growth in the

community. Plant

loading rates even-

tually increased

above design levels,

and NPDES permit

requirements

were becoming

more stringent for both nitrogen and

phosphorous. Furthermore, a limited

footprint was available for expansion.

The town and its consulting engi-

neer, Tighe & Bond, considered many

potential solutions to address these is-

sues, including a system upgrade using

Membrane Bioreactor (MBR) technol-

ogy. During an evaluation of treatment

alternatives it was recognized that,

while MBRs can provide high-level

treatment in a small footprint they can

also be energy-intensive

and relatively expensive

to own and operate.

Taking this informa-

tion into consideration,

the town decided to

explore the BioMag™

ballasted biological

treatment system, an

emerging new technol-

ogy from Siemens Water

Technologies.

The BioMag system

enhances biological wastewater treat-

ment processes by using magnetite to

ballast biological fl oc. With a specifi c

gravity of 5.2 and a strong affi nity for

biological solids, magnetite substan-

tially increases the settling rate of the

biomass. This provides the opportuni-

ty to increase mixed liquor suspended

solids (MLSS) concentration. Higher

MLSS concentration enables the

treatment of increased hydraulic fl ows

or surges and loadings, all within the

same tankage.

The town agreed to fi rst pilot this

innovative technology on one of the

facility’s three activated sludge trains.

Plant operators set several objec-

tives for the trial: demonstrate that

the new system was a cost-effective

alternative to MBRs; identify whether

converting the existing activated

sludge system to the BioMag system

could increase overall plant capacity

from 0.75 mgd to 1.6 mgd without

adding additional bioreactor or clari-

fi er capacity; and determine whether

the system would enable the plant to

meet all permit limits, achieving < 10

mg/L total nitrogen and < 0.2 mg/L

total phosphorus.

Filtration Upgrade

Concern regarding future tighten-

ing of phosphorus limits, along with a

desire to have a reliable tertiary treat-

ment process to work in conjunction

with the BioMag system, the Stur-

bridge plant then turned its attention

to expanding the existing conventional

media fi ltration system. A demonstra-

tion showed that the installed cost

of an expanded sand fi lter would be

greater than that of a smaller and

higher-performing CoMag™ system,

also from Siemens Water Technologies.

The CoMag system is a solids and

particulate removal process that produc-

es effl uent equivalent to ultrafi ltration,

at lower capital and operating costs than

conventional alternatives. It competes

effectively with all forms of media and

membrane fi ltration and conventional

clarifi cation. These benefi ts, along with

the advantages of a smaller footprint, no

loss of productivity to clogging, plug-

Operators have several options for

dealing with odor control problems

associated with wastewater treatment

ponds, from increasing the aeration

to applying chemicals to the water or

perfume to the air. But often these

solutions are expensive and not totally

effective. Another alternative—long-

distance circulators or mixers—has

emerged as a method for controlling

odors in many wastewater ponds.

These mixers are installed on the

pond’s surface and consist of a solar-

powered or grid-powered motor, an

axial fl ow impeller that pulls water up

from the intake to the surface where

is it spread out at 360 degrees, an

adjustable-depth intake hose, and a

power control system.

Long distance circulators are differ-

ent from any other reservoir equip-

ment in that the adjustable intake takes

advantage of the manner in which

water forms thin horizontal layers in

ponds, and allows a precise horizontal

cross-section of water to be circulated

throughout the entire pond footprint.

This circulated zone can be indexed to

the top of the pond, such as a setting

to circulate just the top X feet of the

pond, or the intake hose can be set to

circulate the entire depth of the pond

regardless of how full the pond is.

This article discusses how this unique

characteristic allows long distance mix-

ers to control odors in two types of

wastewater treatment ponds, equaliza-

tion ponds and anaerobic ponds.

Equalization Ponds

An equalization pond in front of a

wastewater treatment plant acts as a

shock absorber by temporarily holding

excess infl ow during rain events until

the water can go through the treat-

ment plant.

For example, an equalization basin

may be designed to hold eight million

gallons of water when full at eight feet

deep, but normally be operated with

two million gallons in the pond at a

depth of three to four feet, with one

million gallons per day entering the

pond and going through to the treat-

ment plant. During a heavy rain, the

equalization pond may quickly fi ll to

the depth of eight feet and then, a few

days later, be back down to three feet.

In this type of pond, without thor-

ough mixing, the organic solids enter-

ing the pond will tend to settle to the

bottom and, over time, the anaero-

bic digestive process at the bottom

can create ongoing odor problems.

But by keeping the solids and water

thoroughly mixed, the solids move

on to the plant instead of settling to

the bottom, and the detention time

of both the water and the solids is too

short for the anaerobic process to cre-

ate an odor problem.

In these ponds, the unique design of

a long distance circulator, set with the

intake hose all the way to the bottom of

the pond, will automatically allow full

mixing of the pond as it goes through

depth changes, without any adjustment

being needed and without damaging

the bottom of the pond in any way.

Anaerobic Ponds

Some wastewater treatment ponds,

such as waste sludge storage ponds in

activated sludge systems, are purposely

designed for anaerobic digestion and

thus produce sulfi des and odors

continuously throughout most of the

pond depth. To eliminate odors ema-

nating from these ponds, operators can

maintain an oxygenated layer of water

at the surface of the pond, sometimes

called an “odor cap.” When sulfi de

gas bubbles rise toward the surface of

the pond, they are instantly oxidized

to non-odorous sulfate as they pass

through the oxygenated odor cap.

A thin odor cap at the top of the

pond, even 1 inch thick, is all that is

required to neutralize sulfi de odors.

But a thin odor cap can be disturbed

by wind, which would then let odors

escape, so usually it is best to have a

one- to three-foot thick odor cap.

Floating circulators are ideal for

creating an odor cap on top of the

pond, because their intake hoses can be

set for a shallow water depth, usually

1-3 feet, and because one machine will

circulate to the edge of the pond in

all directions. Consequently only one

machine is usually needed per pond.

Circulators maintain the oxygen in the

odor cap through two mechanisms, (a)

capture of photosynthetic oxygen dur-

ing the daylight hours, and (b) surface

re-aeration during the nighttime hours.

Since the machine is not bringing up

any BOD loading from deeper water,

because there is no turbulence, usually

there is no problem in maintaining oxy-

gen in the odor cap 24 hours per day.

Regardless of what type of equip-

ment is used to create and maintain an

odor cap on an anaerobic pond, three

practices are crucial to proper odor

control in an anaerobic pond:

1. Infl ow to the pond should be kept

below the odor cap, so that the

infl uent BOD does not use up the

oxygen in the odor cap. If the odor

control plan calls for a three-feet-

thick odor cap at the top of the

pond, the infl ow should be brought

in horizontally at four feet deep or

deeper. If an old pond is converted

to sludge storage and the horizontal

infl ow pipe is not deep enough, than

add a baffl e or 45-degree elbow with

a short pipe extension so that the

infl ow water does come in below the

odor cap. And in ponds where the

infl uent water enters vertically at the

bottom of the pond, place a defl ec-

tor, similar in shape to a card table,

over the infl uent pipe to defl ect in-

coming water into a horizontal pat-

tern instead of allowing it to shoot

up to the surface of the pond.

2. Similarly, the effl uent should also

be drawn off the pond from below

the odor cap. This prevents the

oxygenated water that comprises

the odor cap from being drained off

the pond. If an old pond is being

converted to use for sludge storage

and it has a skimming outlet pipe,

devise an anti-skimming baffl e, or

45-degree elbow and short pipe

extension, to allow water leaving

the pond to come from below the

odor cap. WW

Using Circulators to Control Wastewater Pond OdorsBy Joel Bleth ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After repeated pump failures at

the Infl uent Pump Station for the

Williams-Monaco Wastewater Treat-

ment Plant operated by the South

Adams County Water and Sanitation

District (SACWSD), it made more

sense to replace rather than repair the

existing infl uent pumps.

The SACWSD plant, located in

Henderson, CO, receives an average

fl ow of 3.5 mgd, with 6 mgd spikes

on weekends, from more than 250

miles of 8” to 30” collection lines

serving 50,000-plus customers in the

65-square-mile service area North of

Denver.

The William-Monaco WWTP has

undergone three major expansions. In

1980, the new east side of the plant

was constructed with rotating biologi-

cal contactors (RBCs) for secondary

treatment. In 1994 a bio-tower trick-

ling fi lter system was added as well to

the east side of the plant to supple-

ment the RBCs and a shallow rock

media trickling fi lter that is located on

the old plant’s west side.

In 2004 the plant underwent yet

another expansion that involved the

demolition of the old RBC sys-

tem, the addition of a moving bed

bio-reactor, and the addition of a

new sludge digester, administrative

building and garage that enabled the

facility to comply with more strin-

gent regulations addressing nutrient,

nitrogen, chlorine, and bacterial levels

in the treated effl uent discharged

into the South Platte River. The work

increased the plant’s capacity from 4.4

mgd to 8 mgd.

Ironically, these improvements

coincided with recurring

pump problems at the

headworks. As part of the

2004 expansion, the district

had replaced a series of

1980s-vintage long-shaft

pump motors with four,

60 hp submersible pump

motors but kept the dry

pit confi guration of the old

pumps in the 27-ft. deep

basement of the three-level

infl uent station.

The pumps were de-

signed to operate individu-

ally until suffi cient fl ows oc-

curred to activate a second

unit. The pumps cycled in

an alternating sequence,

a common operations

concept intended to equal-

ize the wear on multiple

pumps in a station. It was

therefore easy to conclude

that all of the headworks

pumps began experiencing

problems around the same

time due to their age, equal wear and

other shortcomings.

Wear and

age, coupled

with vibra-

tion, sudden

jolts when

the units

shut off, air-

locking and

inadequate

cooling con-

tributed to

the utility’s

mounting

maintenance

issues. Fore-

most among

maintenance

concerns was

the erosion

of seal integ-

rity of the

pumps that

allowed leaks resulting in accelerated

bearing wear.

After repair costs had grown to

an unacceptable level, staff proposed

replacing one of the pumps. Based

upon price, performance, and war-

ranty, the Water Technology Group

of Cogent, a Denver-based water and

wastewater treatment and pumping

systems specialist, was chosen by the

district. Water Technology Group rec-

ommended replacing the 60-HP unit

with a 60-HP Flygt N-Pump.

Wastewater personnel carefully

studied the advanced features of the

new-generation pumps as they related

to the problems experienced at the

district’s infl uent pump station. Staff

also toured another plant that was

equipped with the pumps operating in

a similar dry pit installation.

The Flygt brand pump, manu-

factured by Xylem, incorporated

advancements absent in the existing

pumps, including a patented impeller

known for its clog resistance, ability

to handle modern trash, and energy

saving operation. The replacement

pump’s performance claims became

evident in the monitoring by the util-

ity’s SCADA system.

District wastewater staff noted

the N-pump immediately reduced

energy consumption, drawing 25 to

35 percent fewer amps. The energy

savings, operational performance, and

fi ve year warranty earned the district’s

confi dence and decision to replace the

rest of the existing headworks pumps

in the next budgeting cycle.

Over the course of a three-month

period, one by one the existing trou-

blesome pumps were replaced as they

failed or as the work load allowed.

Water Technology Group specialists

also noted other features that favored

the N-Pump for the remaining re-

placements. A primary feature was the

double tungsten carbide seals whose

mechanical strength would withstand

thousands of hours of high-pressure

operation under extreme conditions.

Cooling would also improve because

the pumps employed a glycol-based,

closed-loop motor cooling system,

unlike the plant water used to cool

the old pumps. Finally and perhaps

foremost, all Flygt N-pumps are

specifi cally engineered to reduce shaft

defl ection resulting in less vibration,

a nemesis the district’s staff blames

for many repairs needed by the old

pumps. The fi ve year warranty was an

added bonus appreciated by manage-

ment.

District staff partially engineered

the replacement program in-house

with the local offi ce of Burns &

McDonnell providing backup exper-

tise. The engineering fi rm modeled

and reviewed the pump curves to

verify the delivery rates of the former

pumps. They designed new header

connections for the new pumps, and

oversaw the installations and submit-

ted reviews. The fi rm also conducted

vibration tests that confi rmed the new

pumps would operate without the

vibration that had plagued the old

submersible dry-pit pumps for years.WW

Pump Upgrade Resolves Shaking, Leaking Seal Problems

South Adams County Water and Sanitation District (SACWSD) has experienced signifi cant en-ergy savings after replacing aging 60 hp long-shaft pumps with these Flygt 60 hp submersible pumps in a dry pit confi guration.

Elastomer Valves Provide Solutions in Backfl ow, Slurry ApplicationsBy Chris Raftis --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The most critical part of any valve is

its engineering and construction. Elas-

tomer valves are built to specifi cally

provide low maintenance and long life

span in the toughest applications. The

design of an elastomer valve provides

trouble-free, high wear-resistance that

outperforms and outlasts many other

valve styles.

Elastomer valves are ply reinforced,

much like an automotive tire. Special

plies of nylon, polyester and Kevlar

fabrics provide the structural support

within an elastomer valve and form

the pressure-containing vessel. The

wear surface of an elastomer pinch

valve is vulcanized to the ply and is

chosen on the basis of compatibility

with the process fl uid. Elastomer

valves can be built to suit almost any

process condition. Large-diameter and

high-pressure designs are available, as

are variations in elastomer thickness

for severe conditions.

Year after year, millions of dollars

are spent in the United States when

CSO systems allow receiving waters

to enter into sewage treatment plants

and collection systems. The unique

characteristics of elastomer valves

make them ideal for backfl ow preven-

tion in these applications.

Developed specifi cally for CSO

and diversion chamber applications,

elastomer valves such as the Tide-

fl ex® Check Valve and Tidefl ex®

CheckMate® Inline Check Valve can

eliminate backfl ow from oceans, rivers

and interceptors.

Elastomer check valves are designed

to be installed in the upstream or

downstream end of a diversion cham-

ber or pipeline. Simply insert the valve

inside or onto any size pipe and clamp

it into position. No modifi cation to

the pipe or structure is required.

The all-rubber construction of

elastomer check valves provides

trouble-free service because there are

no mechanical parts to fail or corrode.

Their unique design allows for near

100% fl ow and a tight seal to elimi-

nate backfl ow. These valves even seal

on entrapped solids. Their construc-

tion also gives the valves extremely

low headloss.

Elastomer check valves completely

drain the pipeline and are sensitive

enough to open with as little as one

inch of water.

Pinch valves are another type of

valve that use engineered elastomer

technology. At the heart of every

pinch valve is an elastomer sleeve that

can manage the toughest fl ow applica-

tions in sludge

- specifi cally

return and waste

activated sludge,

grit and lime

slurry. The sleeve

provides excellent

corrosion resis-

tance, abrasion

resistance and

pressure containment. Pinch valves are

ideal for both isolation and fl ow con-

trol applications and can be optioned

with customized “cone sleeve” trim.

When abrasive particles strike the

hard surface of traditional metal

valves, the energy of impact is ab-

sorbed by the metal surface -- prema-

turely wearing seats, weirs, rotating

discs, plugs and balls. Additionally,

these abrasive particles pack behind

the ball and plug, scoring the sealing

surface and creating leaks.

When abrasive particles strike the

elastomer surface of a pinch valve, the

impact is absorbed and defl ected back

into the particle. Extremely resistant

elastomers wear at a far slower rate than

ceramics or metal alloy valve trims.

Pinch valves are full-ported with no

crevices or seats to foul valve operation.

Another major benefi t of pinch

valves is that there is no packing to

maintain. Pinch valves provide double

containment without the need for

packing. Therefore, they are often

installed in buried service applications

and if fugitive emissions are a concern.

Accurate, repeatable linear fl ow

control and drop-tight, bi-directional

shutoff make elastomer valves such as

Red Valve Company’s pinch valves ide-

al for infl uent fl ow control and during

pretreatment as wastewater is passed

through a screen to remove grit.

Caustic and chemical solutions,

such as lime are used to equalize

wastewater. These materials present

tough problems for metal valves, but

the elastomer sleeve within a pinch

valve resists abrasion and corrosion.

The fl exing action of an elastomer

sleeve breaks apart dewatered solids

each time the valve is actuated, even

after long periods of inactivity. In

sludge, waste activated and return

activated applications where the per-

cent solids is greatest, pinch valves can

outperform all other valves. WW

Vibration Analysis Helps Identify Pump Problem

The operators at the Beaver Dam,

WI, wastewater treatment plant knew

there had to be a better way to meet

their 1.0 mg/L total phosphorus

limit. They struggled to feed enough

ferric chloride to handle the incoming

phosphorus spikes without overfeed-

ing, which would increase sludge

production and waste chemical.

To automate the process, staff

acquired a new RTC101 Chemical

Phosphorus Optimization Solution

from Hach. The new system auto-

matically feeds the exact amount

of precipitant needed to maintain

a programmed orthophosphate set

point. By measuring effl uent fl ow

and orthophosphate in real time,

the controller uses preprogrammed

algorithms to automatically adjust the

ferric chloride dose ahead of the clari-

fi ers as the phosphorus load changes.

If a real time measurement signal

is lost, the controller will switch to

previously entered data until the signal

is restored.

At Beaver Dam, the installation was

simple. The orthophosphate analyzer

measures plant effl uent every fi ve

minutes and sends that measurement

to the real time controller (RTC)

installed in a PLC cabinet along with

the measured effl uent fl ow readings.

The system then outputs the fer-

ric dosing signal through the PLC

to control the chemical feed pumps

based upon the set point programmed

into the controller.

The system was installed, confi g-

ured, and operational in less than 48

hours. The lab’s test results correlate

almost perfectly to the RTC101’s

phosphorus readings.

Even with substantial pretreat-

ment, infl uent phosphorus spikes

are common at Beaver Dam due to

industrial discharges and other unfore-

seen events. When the system senses

the load of phosphorus changing, it

increases the ferric chloride dose to

maintain the 0.60 mg/L orthophos-

phate set point.

Previously, the staff maintained an

average ferric chloride dose of 12.5

gallons per hour. After the installa-

tion, the average feed is 5.55 gallons

per hour—savings of 56% in ferric

chloride costs alone. At this rate, the

savings will have paid for the system in

less than 12 months.

Moreover, although not yet quanti-

fi ed, the staff believes that an associ-

ated decrease in sludge production

provides additional savings stemming

from reduced solids handling costs.

The water treatment facility in the

City of Fairfi eld, Ohio, uses vibra-

tion analysis as part of its condition-

monitoring planned/predictive

maintenance program to help verify

and assure equipment is operating

satisfactorily. The Water Treatment

Plant processes an average 5.1 mgd

for a population of 44,000 people

with a customer base of approximately

14,000 accounts.

Public Utilities Superintendent

Andreas Eddy initiated the vibration

analysis program as part of a cost sav-

ings measure with regard to “total”

operating cost of equipment associ-

ated with the water treatment process.

The intent was to identify potential

equipment problems at an early stage

and to allow maintenance work to be

performed on a proactive basis.

Vibration data was collected with the

Vixpert 2-channel vibration analyzer

and plotted with Omnitrend software

by Prueftechnik/Ludeca. The system

helped identify a “Severe Mechanical

Looseness” problem on a pump in-

stalled at a pumping station considered

critical to the city’s water system.

Initial baseline measurements of the

unit revealed the mechanical looseness

and a possible coupling problem with

the pump and motor assembly. The

vibration data showed severe impact-

ing with high frequency harmonics

characteristic of looseness of both

pump bearings.

It was sus-

pected that the

looseness could

be simply loose

bolts on the

bearing mounts

and fl anges, or a possible worst case sce-

nario of internal looseness of the bearing

components themselves.

The vibration analysis condition-

monitoring survey report recommend-

ed that staff check all mounting and

fl ange bolts of the bearing itself and

to inspect the condition of the “steel

grid” type motor-pump coupling.

The majority of the mounting bolts

associated with the pump-bearing fl ange

and pump supports were found to be

very loose. Inspection of the motor-

pump shaft coupling also revealed a lack

of proper lubrication around the steel

grid component. After corrective action,

follow-up vibration measurements were

taken to verify satisfactory results. WW

Process controls for water treatment

Industrial, Municipal and Wastewater Solutions

in biomass. Anaerobic digestion and

dewatering produce a sidestream with

a high nutrient content. Recover-

ing nutrients from that concentrated

stream can be more economic than

recovery from main-stream processes.

Wendell Khunjar of Hazen and Sawyer

will present a paper entitled “Economic

Evaluation of Alternatives for Sidestream

Nutrient Removal and Recovery.” He will

discusses different strategies for treating

and recovering nitrogen and phosphorus

from that sidestream.

“We will discuss four case studies

representative of treatment facilities that

are experiencing really stringent nitro-

gen limits and have to deal with a large

fraction of their nutrient load coming

back in their sidestream,” Khunjar said.

From a nitrogen perspective, he

will discuss removal of nitrogen using

conventional nitrifi cation/denitrifi ca-

tion or using novel strategies includ-

ing nitritation/de-nitritation as well as

deammonifi cation.

He will also discuss recovery of both

nitrogen and phosphorus in struvite.

“Struvite recovery allows you to

recover up to 90 percent of the phos-

phorus but also allows you to take out

about 25 percent of the nitrogen,”

Khunjar said. “In some facilities, that

25 percent reduction might be suf-

fi cient to allow that nutrient stream to

come directly around to the head of

the plant and not have an impact on

mainstream treatment.”

As plants begin to embrace biologi-

cal phosphorus removal, they often

also experience an increase in prob-

lems caused by struvite. Dealing with

that nuisance and also recovering a

marketable product can make eco-

nomic sense, Khunjar said.

“Right now there are 20-25 plants

who have done piloting or some

type of evaluation and that number

is growing,” he said. “Everyone is

very interested in understanding if it

(nutrient recovery) makes sense from

an economic perspective. Sometimes it

does and sometimes it does not.”

Conclusion

Sansom said the facilities she exam-

ined in her study were all working to-

ward a future of tight nutrient limits.

“They are looking more long-term

and how to phase in these require-

ments,” she said. “They are not ready

to stick an RO plant at the back of

their facility to achieve these limits,

but they are looking for ways to move

forward and how can they incorporate

even upstream reductions of nutrient

loading in the source water.”

The process of setting nutrient crite-

ria is slow and frustrating at times, but

it is an important process that requires

careful deliberation, Bhattarai said.

“The nutrient problem was not cre-

ated overnight and we cannot solve it

overnight,” he said. “It’s probably better

to take some initial steps and, gradually,

using an adaptive management strategy,

work toward achieving compliance.”

“The title of our paper is the Texas

Two Step. In the end, we say the

Texas Two Step still goes on,” he said.

“We’re still dancing.” WW

System offers Odor Control for Plants with High Gas ConcentrationsWastewater treatment plants often

need to control the “rotten egg” odors

resulting from their waste and sewage

treatment processes. The unpleas-

ant odors in and around wastewater

plants are mainly caused by H2S, but

other odorous

compounds can

include mercap-

tans, amines,

aldehydes, and

ketones.

In higher gas

concentration

applications,

one alterna-

tive is Purafi l’s

Biological Air

Treater (BAT),

which features

a propri-

etary fi xed-

fi lm trickling

fi lter technol-

ogy. Offered

through an exclusive license with

Honeywell Process Solutions, the

system can provide more effi cient

and cost-effective odor abatement

and VOC treatment than other bio-

logical removal systems.

Whereas other biofi lters are chal-

lenged to maintain proper moisture

and reduce pressure drops, the mixed

media of foam cubes and spacers in

a standard BAT have been proven to

accomplish more than 99% removal

of hydrogen sulfi de gas. The polyure-

thane foam cubes provide incredible

surface area per unit volume to host

microbial biofi lms.

Polypropylene spacers supply

substantial void volume and struc-

tural integrity for tall beds, as well as

enhanced mass transfer and excellent

hydraulic dispersion and distribution.

The unique mixed-media support

allows for control of surface area and

void space. Ratios of foam-to-plastic

vary with engineering design and ap-

plication, and are used to control the

biofi lm depth and pressure drop.

Purafi l provides design assistance to

the customer, to select the appropriate

equipment based on the customer’s

requirements. The BAT system can

be used to treat low and high airfl ows

with hydrogen sulfi de concentrations

ranging from 25 ppm to 1000 ppm.

The system operates on electrical

power and water supply. The water

source can be either potable or re-use

water from the wastewater treat-

ment plant with at least 60 psi. The

amount of water required to rinse out

the sulfates generated by the biologi-

cal reaction (usually 5-25 gpm) will

depend on the H2S concentration. In

a typical wastewater treatment plant

application, using secondary treated

effl uent as a water source is recom-

mended; not only is it economical,

but this type of water often carries the

nutrients needed by the bacteria in the

biotrickling fi lter.

In order to design the appropriate

biotrickling odor removal system, the

following information is required:

1) Airfl ow

2) Gas concentrations (average and

peak conditions)

3) Required removal effi ciency (normal-

ly 99% for H2S and 90% for total odor)

4) Temperature of the airstream (this

will normally be ambient but varia-

tions must be known)

5) Availability and quality of the water

(including fl ow and pressure if possible)

6) Odor source (e.g. headworks,

pump station, sludge storage, etc.)

An optional dry scrubbing polish-

ing system is available to end-users

and can increase the odor removal

effi ciency to more than 99.5%.

With any BAT sold, Purafi l provides

the vessel, media, blower and motor,

recirculation pump, nutrient pump,

complete water control cabinet, elec-

trical control panel, system start-up

and inoculation. Honeywell controls

are offered as standard equipment on

all Purafi l BAT systems. A detailed

scope of supply can be provided for

any application. WW

Earlier this year Headworks BIO

signed an option agreement with the

Texas A&M University System (TA-

MUS) that provides the company with

the right to negotiate an exclusive

license for TAMUS’ patent pending

Electron Beam (E-Beam) technology

for use in municipal wastewater treat-

ment applications.

The National Center for Electron

Beam Research (NCEBR) at Texas

A&M in College Station, TX, is the

leading academic and research or-

ganization focused on the research,

development, and commercializa-

tion of E-Beam and X-ray technol-

ogies. The activities of the NCEBR,

conducted by Texas AgriLife Re-

search, hinge around of the world’s

largest high-throughput research/

commercial grade E-Beam and X-

ray irradiation equipment.

Electron Beam processing or

electronic irradiation is a process

which involves using electrons,

usually of high energy, to treat an

object for a variety of purposes.

Possible uses for electronic irradia-

tion include sterilization, disinfection,

to cross-link polymers, and modify

materials.

This process has the ability to break

the DNA molecules in microorgan-

isms resulting in microbial death and

rendering the product or sample ster-

ile. E-Beam processing is currently in

use commercially for the sterilization

of medical products and pasteurizing

food to protect against foodborne

pathogens.

Wastewater Applications

The NCEBR is researching ways

to harness E-Beam and X-ray tech-

nologies to treat municipal drinking

water, wastewater, and industrial waste

streams. It is hypothesized that high

energy (10 MeV) Electron Beam

technology might one day be used to

disinfect municipal biosolids to Class

A standards, disinfect wastewater ef-

fl uents, reduce estrogenic activity in

sludges and effl uent, and potentially

reduce digester residence time and

enhance methane production.

E-Beam disinfection or sterilization

is powered by electricity and can be a

quick “switch-on, switch-off technol-

ogy” that can be used to treat material

that is fl owing through pipes or on

conveyor belts. It can oxidize organics

and inactivate microbial pathogens.

Studies performed at Texas A&M

demonstrate that E-Beam technol-

ogy can be used on sludges at varying

doses to obtain sludge that meet Class

A specifi cations. WW

WEFTEC EXHIBITORS


A new membrane treatment system

that will be on display at WEFTEC

features a low-pressure polymeric

membrane with fi bers specially con-

structed to never break. Not only do

these “no-break” fi bers save the end

user the cost of repairing fi bers, but

they also have higher permeability,

more resistance to fouling, and less

power/chemical requirements than

other MF and UF membranes, ac-

cording to the manufacturer.

The Aqua UltraFiltration system,

offered by Aqua-Aerobic Systems, uses

special hollow-fi ber membranes manu-

factured by inge GmbH, a division of

BASF, at their production facility in

Greifenberg, Germany. Unlike other

hollow-fi ber membranes, where each

fi ber is a thin strand with a single bore

running through it, each inge fi ber

has seven bores running through it.

In addition, this patented Multi-

bore® fi ber is made from a single ma-

terial. The result is analogous to the

strength of a rope made from several

cords put together: other membrane

manufacturers use a single membrane

fi ber, while inge has melded seven

fi bers together to form a stronger,

multibore fi ber.

Most other membrane fi bers are

manufactured using a thermally

induced phase separation (TIPS) pro-

cess, while the Aqua UF membrane

is made with a solvent-induced phase

separation (SIPS) process. While the

TIPS process creates a stronger and

thicker membrane, the SIPS process

produces a membrane with higher

permeability and lower transmem-

brane pressure (TMP), which results

in a system with fewer membranes and

lower pumping costs to treat the same

fl ow. The SIPS process weakens the

typical single-bore fi ber, but doesn’t

diminish the strength created by the

multibore construc-

tion of the inge

fi bers.

The membranes

used in the Aqua

system are made of

polyethersulphone

(PES). Most MF

and UF membranes

are made of poly-

vinylidene fl uoride

(PVDF) because

it is more fl exible

(less brittle) than

PES and is more

resistant to chlorine

and other oxidants.

However, the dif-

ference in fl exibility

between the two

materials has abso-

lutely no bearing

on the strength of inge’s multibore

fi ber. Because PES is cleaned with

caustic - and not chlorine, as PVDF is

– the difference in chlorine resistance

is no longer signifi cant.

Since material strength and cho-

rine resistance are not issues with the

multibore fi bers, PES is used because

it gives several advantages over PVDF

that result in lower O&M costs:

• PES is more hydrophilic than

PVDF, so solids have less tendency

to “stick” to the membrane surface.

This means that less backwash water

and cleaning chemicals are needed to

remove the solids.

• Pores in PES can be made smaller

and more uniform than in PVDF. As

a result, less pressure is required to

get the same fl ow through the same

membrane area. Also, more viruses are

rejected; the inge membrane is rated

for 4 log virus removal.

• PES can be cleaned at higher pHs

than PVDF. Since caustic is better at

dissolving organics than chlorine, less

chemical is needed.

Better Backwash Effi ciency

During fi ltration on most MF

and UF membranes, the feed water

fl ows from the outside of each fi ber,

through the fi ber material, to the bore

inside the fi ber. In contrast, fi ltration

on the Aqua UltraFiltration system

is from inside each multibore fi ber to

the outside of the fi ber. To make sure

the solids are fi ltered out evenly over

the full length of the fi ber, fl ow to the

fi ber is alternated between the top and

the bottom of the membrane module.

The advantage of the in-to-out fl ow

path really occurs during the periodic

backwash cycles, where the fl ow is

reversed. On standard out-to-in mem-

branes, there is a drop in pressure as

the backwash water fl ows up through

the inside of the fi bers such that the

fl ow through the bottom of the fi ber

is more than through the top of the.

In addition, compressed air is needed

to remove the solids that collect on

the outside of the fi bers at the bottom

of the module.

On the in-to-out membranes used

by the Aqua system, there is no pres-

sure difference between the back-

wash water entering the top of the

fi bers and that entering the bottom

of the fi bers, so the backwash fl ow is

even. Less backwash water is needed

to achieve the same level of solids

removal. Also, air is not required

because there is nowhere for the

solids to collect; therefore, the system

doesn’t have blowers to maintain and

uses signifi cantly less power.

Lower Plugging Tendency

While the commonly-held belief

is that in-to-out membranes have a

higher tendency to plug with solids,

the opposite is actually true of the

Aqua UF membrane. There are several

reasons for this:

• The diameter of each fi ber bore

is larger than other in-to-out mem-

branes; 0.9 mm bores are used for

waters with average infl uent turbidities

up to 50 NTU, and 1.5 mm bores are

used for waters with average infl uent

turbidities up to 200 NTU.

• The hydrophilic nature of the

membrane minimizes solids accumula-

tion on the membrane surface.

• The in-to-out fl ow path means

there are no solids to collect on the

outside of the fi bers; this is the main

reason for plugging of out-to-in mem-

branes.

• Coagulant is often injected into the

infl uent, which lowers the tendency of

the solids to adhere to the membrane.

When a small amount of coagulant

is added to the infl uent, fewer mem-

branes are required to obtain the same

system fl ow and less backwash water

and chemicals are needed to clean the

membranes. This offsets the cost of

the coagulant such that there is actu-

ally a net savings in operating costs.

Solids separation

Salsnes Filter manufactures solids

separation technologies for municipal

and industrial applications. Solids sep-

aration, sludge thickening and dewa-

tering - three critical water treatment

processes - are performed within one

compact, automated unit. Within a

very small footprint, 40-80% TSS and

20-35% BOD are removed and drier

sludge (20-30% DM) is produced.

The system can augment, enhance

or completely replace conventional

primary treatment, making it ideal for

plant upgrades/expansions. Salsnes Filter

Screening, washing

The Spiralift SL provides fi ne screen-

ing, washing, transporting and

compacting of wastewater solids while

leaving essential organics in the fl ow.

It can be installed in existing chan-

nels, reduces solids disposal costs and

protects downstream equipment.

Provided as a fully

integrated system,

it includes a shaft-

less screw screen, a

Taskmaster® Grinder

and control system

which coordinates the

system’s normal and

special functions. The

PLC driven unit uses

fl ow level data to cycle the screw to

minimize power and wear. These units

are provided standard with stainless

steel screens and screw housings.Spiralift, Franklin Miller Inc.

Odor control

OMI Industries

offers natural

odor neutraliz-

ing products. Its

Ecosorb® formula has been successful

in industrial settings dealing with year-

round malodor problems including

municipal and industrial wastewater

treatment plants. It is suited for odors

generated in varying degrees through-

out the wastewater treatment pro-

cess, including those associated with

pump stations, head works, clarifi ers,

digesters, aeration basins, lagoons and

sludge handling areas. OMI Industries

www.omi-industries.com


Submersible propeller pumps

Xylem’s Flygt Submersible Propel-

ler Pumps move large volumes of

water within low to medium

head applications. They

are smaller than non-

submersible offerings as

the motor and hydraulics

are integrated into

one compact unit,

resulting in smaller

pumping stations that

are less complex and thus more cost

effective to build. Operating sub-

merged they take up less space while

noise and motor cooling problems are

eliminated. Xylem – Flygt Products

www.fl ygtus.com


Intake screens

Delta Screens offers passive, t-shape

intake screens. When installed parallel

to the current fl ow, the proven design

effi ciently collects a consistent rate of

incoming water fl ow without plug-

ging or harming aquatic life. With no

moving parts to jam, clog or wear out,

the intake screens require little to no

maintenance. The simplistic design

maintains constant fl ow rates across

the length of the screen, which is criti-

cal to maintain average fl ow velocity.Delta Screens

www.deltascreens.com


Ductile iron pipe

The new NXT DDP product line

from U.S. Pipe takes advantage of

technology advancements to pro-

vide better joint defl ection, pumping

costs, and corrosion protection, when

compared to previous water transmis-

sion systems. Allowing joint defl ection

up to seven degrees the NXT gasket is

available in both restrained and non-

restrained versions. The unique design

allows lower insertion forces than

previous “push-on” gasket designs. US Pipe and Foundry Co.

Vortex fl ow insert

The Vortex Flow Insert from

IPEX USA helps eliminate

odorous emissions and mini-

mize corrosion in vertical sewer

drops. With no moving parts

and requiring virtually no

maintenance, the inserts have

delivered signifi cant cost sav-

ings in monthly chemical feed,

The Duperon® Washer Compac-

tor is a simple, non-batching process

machine that cleans and compacts

screenings of less than 4” at rates of

up to 60 cu. ft/hour. A self-adjusting

compaction housing allows for the

processing of all debris – from grease

and septage to rocks, clothing, and

metal. Posi- tive displacement

employed by

CORROSION CONTROL

By oxidizing dissolved H2S, a Vortex

Flow Insert in a municipal sewer

drop can significantly reduce

concrete and metal corrosion,

extending sewer life and saving the

municipality money.

CHEMICAL FREE ODOR CONTROL

By increasing dissolved oxygen

levels in wastewater and oxidizing

sulfides and other odorous

compounds, the Vortex Flow Insert

eliminates the need for costly

chemical injec�on, high‐maintenance

biofilters and air scrubbers.

LOW MAINTENANCE

With no moving parts, the Vortex

Flow Insert operates virtually

maintenance free drama�cally

reducing maintenance costs of

manholes and sewers.

BUILT‐TO‐SPEC FOR ANY SIZE

Manholes, chambers and pumping

sta�ons are built in a variety of sizes.

Each Vortex Flow Insert is custom

designed based on the peak flow

that the unit is required to handle.

Vortex Flow Inserts from IPEX are a proven method for dealing with odor and

corrosion in sewer drops. Simple, cost‐effec�ve and reliable, Vortex Flow Inserts

have been proven to deliver significant cost savings across North America.

Using the wastewater’s own flow energy to suppress turbulence, aerate the

sewage and oxidize dissolved hydrogen sulfides (H2S), the Vortex Flow’s patented

spiral design sucks odorous gases downward towards the bo�om of the

structure where they are entrained back into the sewage flow.

Nearly 80% of all electrical related

incidents in the industrial sector are

the result of arc fl ash, resulting in over

600 fatalities and 30,000 injuries a

year. An estimated 5 to 10 arc fl ash

injuries occur every day, with treat-

ment estimated to exceed $1 million

per case. Although the probability is

low of arcing occurring, the potential

damage to both employees and facili-

ties can hardly be ignored.

Until recently, electrical safety

standards primarily revolved around

preventing fi res and electrocution of

employees. Increasing arc fl ash aware-

ness in the industry culminated in a

major revision of the NFPA standard

in 2002, mandating the use of arc

fl ash hazard labels on equipment.

Employers may often falsely believe

that since arc fl ash is not specifi cally

mentioned, nor enforced, in OSHA

standards, that proper training and

labeling are not required. However,

failure to provide adequate safety

training and labels exposes employ-

ers to full liability under the OSHA

“General Duty” clause.

Arc fl ash is a fl ashover of electrical

current through the air from a live

conductor to another and oftentimes

to ground. The temperature gener-

ated can reach 35,000 F, greater than

the surface of the sun. In addition to

the extreme temperatures generated,

employees have been thrown across

rooms and suffered permanent hearing

loss due from the accompanying sound

blast from the explosion. In many

of these cases, the employee would

have been protected from harm if the

employer had stressed proper usage of

safety equipment and procedures.

Due to the nature of arcing faults,

they are inherently diffi cult to predict.

However, there are key risk factors

which can signifi cantly increase the

likelihood of an event. Unfortunately,

many water and wastewater facilities

must remain in continual operation to

keep pace with water demand and are

unable to have a complete plant out-

age. Consequently, the risk of an arc

fl ash incident occurring is substantially

greater, as employees must perform

work on energized equipment.

The moisture-fi lled environment

typically encountered in the water in-

dustry signifi cantly increases the risk of

an arc fl ash incident. If electrical equip-

ment is continually exposed to a damp

environment, it increases the likelihood

of a moisture track developing between

two electrical phases. Under ideal

conditions, this could quickly proliferate

into an electrical fault. It is thus critical

for facilities to ensure that equipment

panels located in damp or wet environ-

ments are properly rated, as well as

ensuring that all conduits are sealed.

Many of the risk factors for arc fl ash

hazards can be prevented by proper

preventative maintenance procedures.

However, with the inability to have

complete outages, regular mainte-

nance overhauls on equipment can be

diffi cult to schedule.

NFPA 70E Task Tables

Can we simply use the NFPA 70E

Task Tables in determining an arc

fl ash hazard? The “simple” answer is

yes and no. NFPA 70E defi nes many

of the typical tasks in which work-

ers will perform on electrical equip-

ment and the corresponding safety

equipment. Although this enables

employees to have a general idea of

what protection they require, the task

tables are not based on the actual

electrical system. Consequently, using

the task tables may result in employ-

ees being either under protected

or overprotected. While one might

believe being overprotected is a fi ne

idea, it prolongs the time an employee

performs tasks and their exposure to

potential hazards. The only way to ac-

curately defi ne the proper protection

is a detailed Arc Flash Hazard analysis

performed as per IEEE 1584.

Arch Flash Hazard Analysis

To coincide with a planned major

upgrade, a large wastewater facility

decided to perform an arc fl ash hazard

analysis and coordination study. Safety

of employees, as well as compliance

with national codes, was at the fore-

front of their decision.

The fi rst step toward performing an

arch fl ash calculation was to contact

the local utility and obtain short cir-

cuit information. It is critical to judge

whether they are giving “realistic” val-

ues, or just conservative maximums,

since higher short circuit values can

often result in lower arc fl ash hazards.

Similar to many wastewater facili-

ties, plant single line diagrams had

been provided for the plant on a

“contract by contract” basis for all of

its retrofi t projects. After over 50 years

of operation, the facility had accumu-

lated multiple versions of single line

diagrams, often depicting confl icting

information. Many critical locations

contained no documentation on

the existing electrical system, or any

record of their construction.

From an operations standpoint,

troubleshooting was exceedingly

complicated, as none of the drawings

could be trusted. The only real way

to gather input for the arc fl ash study

was to fi eld verify what was actually

present and reconstruct the entire

electrical system.

Keeping in line with the recommen-

dations of IEEE 1584, all cable sizes and

lengths, equipment nameplates, breaker

settings, equipment model numbers,

and motor information was gathered for

equipment greater than 50 hp at 480V.

With the exception of 120/208V panels

powered from transformers greater

than 125kVA, low voltage panels were

ignored as their available energy is not

enough to sustain an arc.

As is the case with most arc fl ash

studies, the data gathering phase was

perhaps the most costly and time

intensive. Costs associated with data

collection are often drastically reduced

if the facility cans provide the engineer

with photographs and documentation

on the equipment.

After reconstructing the plant single

line diagram and discussing operating

scenarios with operators, the system

was modeled using commercially avail-

able engineering software. Equipment

device settings were visually displayed

and interpreted by the engineer based

upon industry standards, as well as

engineering judgment.

Severe device incoordination was

immediately noted. Ideally, devices

nearest an electrical fault should oper-

ate fi rst, with the upstream device

responding only if the downstream

device failed to operate. This enables

the healthy portions of the system

to remain in operation, while the

unhealthy portions are removed. In

the example illustrated in Figure 1,

a fault on the MCC bus would have

been cleared by the blowing of the

upstream transformer after a delay of

over 50 seconds. This slow response

likely would have resulted in the com-

plete destruction of the equipment.

Device settings similar to the above

example are all too common, as con-

tractors often do not possess accurate

short circuit information at the time

of their installation. In the absence of

information, as well as to ensure the

motors supplied on their project will

start, breakers are set to the highest

possible setting. Unfortunately, doing

so can lead to signifi cant delays in

responding to faults, and substantially

increase the risks to employees.

After modeling and analyzing the

system, in this particular example, the

engineer was able to lower the dial on

the MCC breaker to clear a fault using

the MCC main breaker in less than

.1 seconds (Figure 2). This resulted

in lowering the arc fl ash hazard from

a “3” to a “0”, and still allowed the

starting of the motors.

Once the results were fi nalized and

discussed with operators, warning

stickers were printed and installed on

the equipment. Although there are

many varieties of stickers available, at

the least stickers should specify the

hazard category, and required safety

apparel for live electrical work.

At the conclusion of the overall

study, the facility possessed a complete

and accurate set of single line dia-

grams, along with safety procedures

that were permanently located near

the equipment for operator use. On

future projects at the facility, contrac-

tors will now have accurate short

circuit information to properly set

protective devices.

Conclusion

Facilities are under continual

pressure to keep pace with the latest

OSHA/NFPA regulation, as well as

deal with staff cutbacks and increased

operational demands. Arc Flash haz-

ard analysis provides a valuable insight

into system operations and provides

other peripheral benefi ts such as ac-

curate single line diagrams, protective

device optimization, and discovering

any potentially dangerous conditions.

Preventing long term outages and

promoting employee safety are the

ultimate goals of arc fl ash calculations.

While the engineer can often drastically

reduce arc fl ash hazards by modifying

device settings, recommending current

limiting fuses, zone interlocking, or

differential protection, there is never a

substitute for the value of preventative

maintenance and safety training. WW

This summer two major contracts

were awarded to upgrade San Fran-

cisco’s Hetch Hetchy Regional Water

System. This marks the beginning of

the home stretch because these con-

tracts represent the last of 81 capital

improvement projects that comprise

the San Francisco Public Utilities

Commission’s $4.6 billion Water Sys-

tem Improvement Program (WSIP).

We’re working our way toward

total completion of the program in

2016, with construction in high gear.

Although the program has been modi-

fi ed and refi ned since its inception

in 2002, when San Francisco voters

approved a bond measure to pay for

seismic improvements, the current

program includes 35 projects within

San Francisco, plus 46 other projects

between the Central Valley and the

San Francisco county line. As we

celebrate Labor Day this year, 74 of

the 81 project, across seven counties,

are either in construction or have been

completed.

This unprecedented infrastruc-

ture development and improvement

resulted in jobs at a time when they

have been needed most. In 2011,

approximately 2.7 million craft hours

were logged on WSIP projects, which

represent wages exceeding $100

million on the projects covered by a

Project Labor Agreement.

Completion of the WSIP is critical.

The devastation caused by

the historic 1906 earth-

quake and the 1989 Loma

Prieta earthquake remind

Bay Area residents that they

live in a “when” – not an

“if” – environment when it

comes to earthquakes.

The SFPUC provides

water services to 2.6 million

residential, commercial and

industrial customers in four

counties across the Bay

Area. The WSIP is a massive

and innovative effort to

prevent a major water sup-

ply disruption to its Hetch

Hetchy Regional Water

System when an earthquake

occurs. It is one of the larg-

est water infrastructure pro-

grams in the nation, and it

is the largest infrastructure

program ever undertaken by

the City of San Francisco.

WSIP projects in this race against

time vary in size and complexity, cov-

ering all aspects of the water system

– from dams, reservoirs, pipelines and

tunnels to water treatment facili-

ties, pump stations and water storage

tanks. These fi nal two recently-award-

ed projects, the Seismic Upgrade of

the Bay Division Pipelines #3 and 4

over the Hayward Fault, as well as

the Sutro Reservoir, represent the

diversity of projects being managed

by our team of engineers, consultants

and contractors. When completed in

2016, the WSIP will safeguard the

health and safety of our community

even in the most severe circumstances.

The Sutro Reservoir project, for

example, located in the heart of

San Francisco, will provide seismic

upgrades and improve reservoir cir-

culation as well as retrofi t the outlet

system to conform to the latest state

health requirements for water storage

basins. The second project, the seismic

upgrade of the two major pipelines

over the Hayward Fault, is one of the

most critical seismic reliability projects

in the WSIP. It is located near the in-

famous Hayward Fault and requires a

very innovative, state-of-the-art design

solution that includes a large under-

ground articulated concrete vault

that could accommodate a 6.5 foot

displacement of the pipeline during a

large earthquake.

While the WSIP has all major proj-

ects awarded and in construction, we

are facing our greatest challenges with

the largest and most complex projects

in construction over the remainder of

the program: the Harry Tracy Water

Treatment Plant-Long Term Improve-

ments; the Bay Division Tunnel; the

New Irvington Tunnel and the Calav-

eras Dam Replacement Project.

The Harry Tracy Water Treatment

Plant project, with an approved bud-

get of $175 million and an estimated

completion date of December 2015,

is approximately 15% complete. With

the discovery of a new trace of the

Sierra Fault during the fi nal design,

this project doubled its scope and now

consists of seismic and hydraulic im-

provements in various treatment units

including expansion of the fi ltration

process capacity by adding fi ve new

fi lters. In addition, the project was

forced to construct a new 11-million-

gallon treated water reservoir to

replace the existing two treated water

reservoirs residing over the fault trace.

The Bay Tunnel, fi ve miles long

and eleven stories below sea level, is

being created using a 600-foot earth

balancing tunnel boring machine with

trailing gear that has penetrated the

fi rst three miles and is headed through

challenging terrain that includes the

very sensitive habitat around the re-

trieval shaft in Newark, CA. As a result

of the environmental constraints, the

contractor has opted to use a frozen

shaft method to create the retrieval

shaft, and will abandon most of the

TBM underground rather than risk

disturbing this habitat to remove the

machine. The entire $307 million

San Francisco Nears End of $4.6 Billion Improvement ProgramBy Harlan L. Kelly ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

SFPUC customers are currently served by 280 miles of pipelines, 60 miles of tunnels, 11 reservoirs, fi ve pump stations and two treatment plants that bring snowmelt from the Sierra Nevada Mountains to the cities that surround the San Francisco Bay. Pipelines and tunnels from the Hetch Hetchy Reservoir cross three major earthquake faults with the potential to interrupt water service for days and weeks.

In June, the New Irvington Tunnel Project achieved a signifi cant milestone when two teams of miners met 420 feet underground to complete a major tunnel section.

The Bay Tunnel, the fi rst bored tunnel under San Francisco Bay, will be built using this 600-foot-long tunnel boring machine.

project is on schedule to be completed

in 2015. Once completed the fi nal

tunnel lining will consist of a 9-foot-

diameter welded steel pipeline.

The New Irvington Tunnel in the

Sunol region is the second of the

three tunnels being built as part of

the WSIP. This 18,660-foot-long

tunnel has a construction budget of

$238 million and is expected to reach

completion in the spring of 2015 us-

ing a conventional tunneling method.

This tunnel is horseshoe shaped with

excavated dimensions of approxi-

mately 12 feet by 14 feet. It is being

excavated through Briones Sandstone

and Tice Shale rock formations, and

through seven secondary fault zones

in four tunnel headings. Two headings

are driven from each end of the tunnel

at surface portals, and two headings

are driven from an intermediate 41

foot diameter by 115 feet deep shaft.

In June, after 13 months of digging,

miners from two of the headings met

up with each other underground.

This ‘hole-through’ allowed the road

header teams from the Irvington

Portal in Fremont and the Vargas

Shaft 4,500 feet away to shake hands

somewhere under the mountainside

and formally complete this section of

tunnel excavation.

The work on this project must be

conducted under a “gassy tunnel”

designation from the state’s health

and safety agency. Originally, the tun-

nel was designated “potentially gassy”

and then was assigned the “gassy”

designation late last year. This has

placed additional obligations on the

construction management team and

contractor for tunnel ventilation, gas

monitoring, and safety practices, but

they are performing at peak levels.

The new tunnel alignment runs paral-

lel and just south of the existing tun-

nel and will greatly assist with main-

tenance and redundancy priorities for

the agency. The fi nal tunnel lining

will be mortar lined, welded steel

pipe, resulting in an 8.5 feet fi nished

diameter.

Our fi nal WSIP project is the

rebuilding of the Calaveras Dam in

southern Alameda County, nearly 90

years old and once heralded as the

world’s largest earth dam. In 2001,

the water levels at the Dam were low-

ered to less than 40 percent of original

capacity because of seismic instability.

The storage is crucial to providing

adequate water in times of drought.

Once the new dam is rebuilt, the dam

will withstand a 7.2 magnitude earth-

quake. The new 210-foot-high earth

and rock fi ll dam will be constructed

immediately downstream of the exist-

ing dam and will have a crest length of

1,210 feet, a base thickness of 1,180

feet, and a crest thickness of 80 feet.

The total volume of the dam will be

approximately 3.5 million cubic yards.

Due to the location of the existing

Calaveras Dam in protected watershed

lands, the project faces many hurdles.

These include building the new dam

in such close proximity to an active

earthquake fault and in an area with

complex geological conditions, ensur-

ing environmental compliance in a

pristine environment with numerous

threatened and endangered species,

as well as the presence of naturally

occurring asbestos, which is found in

the Franciscan Complex mélange and

serpentinite rocks. All of these factors

have led to the implementation of

extraordinary precautions and mitiga-

tion measures to address conditions

and ensure project completion. The

$416 million project broke ground in

September 2011 and is currently 20 Circle No. 97 on Reader Service Card

percent complete.

A smaller but

just as challeng-

ing project, Crystal

Springs Pipeline #2

(CSPL2), requires

the SFPUC to re-

place and repair por-

tions of the 19-mile-

long steel pipeline

that is located within

a major commuter

thoroughfare. First

built in the 1930s,

this pipeline provides

drinking water to

several cities on the San Francisco

Peninsula. CSPL2 is also one of the

most complicated pipelines to replace

due to stringent environmental re-

views, community relations issues and

the fact that much of the pipeline lies

under the Bay Area’s oldest highway,

El Camino Real. Millions of motorists

use it annually, and more than three

miles of the CSPL2 water main is

located beneath it.

The contractor designed a cus-

tom pulley system for this project

to slipline the new pipeline care-

fully through the existing pipe. The

completion of CSPL2 construction

work in the 18 work areas within

seven Bay Area cities is scheduled for

January 2013.

All these projects have undergone

a very rigorous planning and environ-

mental review process that has taken

years. It had been a very long time

since the SFPUC directly engaged in

the types of work demanded by the

WSIP, particularly with tunnels. Our

strategy has helped infuse the entire

SFPUC with new tools and techni-

cal expertise that will pay decades of

dividends to San Francisco residents as

the agency and the City apply lessons

learned and replicate new technologies

from the WSIP to future infrastruc-

ture improvement programs. WW

Municipal and industrial water

managers have many test methods at

their disposal to analyze physical and

chemical parameters (e.g. pH, tem-

perature, turbidity, color, etc.) associ-

ated with water samples. However, the

options available for biological testing

have been signifi cantly more limited.

Conventional culturing methods

require several days worth of incuba-

tion, and even then less than 1% of

the total microbial population can be

quantifi ed with a single test.

A technology that has historically

shown promise is the measurement of

Adenosine Triphosphate (ATP). ATP

is the main energy carrying molecule

found in all living cells, thereby mak-

ing the measurement of ATP a direct

indication of total microorganisms in

a given sample. While this technology

has been historically used for surface

testing for hygiene and surface cleanli-

ness monitoring, recent advances now

allow ATP monitoring to provide fully

quantitative results in essentially any

industry where microbiological moni-

toring and control is needed. Drink-

ing water, cooling water, industrial

process streams, and wastewater are all

non-conventional ATP testing markets

that are now within reach.

This “2nd Generation” ATP mea-

surement technology offers a dra-

matic improvement on conventional

culture testing for the purposes of

microbiological condition monitoring

in water treatment and distribution

systems as well as industrial process

water systems. This test provides

more complete information on total

microorganisms in a portable pack-

age that allows for testing anywhere

while generating results in only a few

minutes after sample collection.

Rapid test results provide operators

with a tool that can not only allow

them to troubleshoot microbiologi-

cal issues on-site, but it can also guide

treatment initiatives and assess their

effi cacy. This usually eliminates the

need for subsequent troubleshooting

or validation visits, and more impor-

tantly prevents the problem from

escalating any further – microbio-

logical contamination events are most

economically solved in their earliest

states of evolution.

Other techniques that focus on the

quantifi cation of indicator organisms

such as Total Coliforms or E. Coli are

helpful to reveal when gross contami-

nation has occurred, but it would cer-

tainly be more desirable to be aware of

problems in their early stages so that

the impacts of contamination events

are minimized or avoided altogether.

While ATP monitoring should

not be considered a replacement for

regulated tests or indicator organisms,

it fi lls an important need in the form

of a rapid non-specifi c measure of the

total microbial population.

Monitoring the total microbial

population of a water system en-

ables the user to assess overall water

cleanliness, and can be used to assess

the threat of biofi lm formation. As

biofi lms develop, they may harbor

additional microbial threats such as

Legionella, Mycobacteria, and patho-

genic amoebae, anaerobic microor-

ganisms associated with corrosion and

odor issues, and nitrifi cation-related

microorganisms.

Municipal Water Applications

• Uncover system vulnerabilities –

Due to the speed that results are

made available, source-to-tap sur-

veys of water distribution systems

can be completed in a matter of

hours. When problems are identi-

fi ed, users can “trace up the line”

to identify pathways of entry or

hotspots in order to isolate and

mitigate the problem.

• Reveal and characterize accumula-

tion and regrowth hotspots – A

key defi ciency of culture tests is the

number of species that are left out

and can go undetected. A common

example of this is the emergence of

nitrifying bacteria in water systems

treated with monochloramine. Since

ATP is in all cells including those

that are not easily cultured, nitrify-

ing bacteria will be detected among

the indigenous population, thereby

detecting nitrifi cation issues in their

earliest stages of evolution.

• Optimize fl ushing cycles – The lack

of tools available for assessment of

line fl ushing can result in signifi cant

wastage of water and time since it is

diffi cult to tell how much fl ushing

is enough. When water operators

use traditional microbiological

methods, equipment can be left in

the fi eld for several days until results

are known. ATP monitoring not

only allows the operator to tell how

much fl ushing is enough, but also

permits fl ushing crews to move on

to the next location as soon as the

cycle is complete with no waiting.

This has obvious economic benefi t.

The Canadian company LuminUl-

tra (www.luminultra.com) offers ATP

test kits suited for use in drinking

water and wastewater applications. Its

Quench-Gone Aqueous (QGA) kit is

appropriate for testing source waters,

treatment process effl uents, treated

water, water tanks, water distribution

systems and point-of-use samples.

It can also be used for disinfected

wastewater effl uents and systems using

intensive tertiary treatment.

The company’s QuenchGone21

Wastewater (QG21W) kit is designed

for testing aerobic or anaerobic bio-

reactors, raw infl uents and collection

system samples. The company also

offers a Deposit and Surface Analysis

(DSA) kit suited for testing slimes

and deposits as well as quantifying

attached growth on biologically active

fi lter media.

Conclusion

2nd generation ATP technology

is a game-changer for a multitude of

industries – including the municipal

and industrial water markets. The eco-

nomic advantages of shortening test

response times from days to minutes

are many, and offer the opportunity to

dramatically improve safety, security

and environmental impact.

One of the greatest advantages to

this technology is the capability of

quantifying total microorganisms,

including those for which culture

tests are not equipped to measure (ie.

nitrifying bacteria, many corrosion-

related bacteria, some protozoa, and

Archaea). Along with other molecular

biology techniques, the fi eld of mi-

crobiological measurement is rapidly

changing, shifting away from the

old culture-based techniques to new

techniques that together operate as a

‘tool box’ that will lead to more rapid

and effective anti-microbial initiatives

in municipal and industrial processes.

Test Kits Help Quantify Microbial Populations in Water

The Water Environment Federation

(WEF) recently published the Solids

Process Design and Management

manual — a comprehensive update

of Process Design Manual for Sludge

Treatment and Disposal originally

published by the U.S. Environmental

Protection Agency in 1979.

Tim Shea, CH2M HILL Fellow

Residuals Management Technolo-

gist and Michael Moore, National

Biosolids Lead at HDR, helped lead

the effort as task force co-chairs. They

were supported by senior EPA staffers

Dr. James Smith and Robert Bastian.

“As the industry’s existing go-to

manual hadn’t been updated in over

30 years, there were a lot of new

processes, technologies, procedures

and best practices that we needed to

make sure were included in the new

WEF manual and that would remain

relevant until we update again in a few

years,” Shea said.

“This was a large undertaking—al-

most fi ve years from inception to pub-

lication—and was only made possible

by the efforts and thought leadership

provided by the Task Force,” he said.

“I applaud everyone on a job well

done in developing this document,

which will be one of the leading refer-

ences in the biosolids management

fi eld for decades to come.”

The publication is intended for

use by professionals engaged in the

design, approval, and operation

of municipal solids treatment and

disposal systems. The new manual ex-

pands the previous manual from 19 to

26 chapters, with contemporary new

material on planning, public outreach

and involvement, and solids produc-

tion and characterization.

Other topics include design ap-

proach, conveyance, conditioning,

thickening, waste minimization,

anaerobic and aerobic digestion, de-

watering, composting, alkaline treat-

ment, disinfection and stabilization,

thermal drying, thermal oxidation,

pyrolysis and gasifi cation, transport

and storage, odor management, side-

streams, instrumentation and moni-

toring, land application and product

distribution, landfi ll management,

emerging technologies, and treatment

and utilization of green gases.

The publication is now available for

purchase from WEF. WW

Above Grade Controls Minimize Confi ned Space DangersBy Mike Pindelski ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Due to the dangers associated with

entering confi ned spaces, municipali-

ties are now, more than ever, address-

ing the issues of below ground pump

stations to protect both entrants into

confi ned spaces and the investment of

systems themselves.

Metropolitan Industries of Rome-

oville, IL, recently renovated three

below ground pump stations, giv-

ing each municipality the ability to

interface with the controls without

entering the confi ned space. Potential

future projects such as submersible

pump retro-fi ts into the existing

wetwell would be the next appropriate

step to completely eliminate confi ned

space entry.

Calumet City, IL

The City of Calumet City required

an emergency rehabilitation project

following the fl ooding of a below

ground water pump station.

“It is suspected that the reser-

voir fi ll valve stuck open causing an

overfl ow condition and thus, water

fi lled the below ground pump sta-

tion,” said Metropolitan Industries’s

Keith Girup. “The existing booster

station was constructed many years

The National Water Research Insti-

tute has published the third edition of

the Ultraviolet Disinfection Guidelines

for Drinking Water and Water Reuse.

The guidelines are designed to

provide regulatory agencies and water

and wastewater utilities with a com-

mon basis for evaluating and imple-

menting ultraviolet (UV) disinfection

of waterborne pathogens such as

viruses, bacteria, and parasites like

Cryptosporidium and Giardia.

The announcement was made by

Jeff Mosher, Executive Director of

NWRI, at the “IUVA 2012 Americas

Conference” held by the International

Ultraviolet Association (IUVA) in

Washington, D.C.

“Because of its advantages demand

for UV is growing, based in part on

the use of recycled water to meet wa-

ter supply needs,” Mosher said. “The

UV Guidelines are the most com-

monly used reference by regulators,

water and wastewater agencies, design

engineers, and equipment manufac-

turers to ensure the effi cacy of UV

installations.”

The UV Guidelines were origi-

nally prepared in 2000 by a team of

water industry experts that included

university researchers, state and federal

regulators, and consultants from the

U.S. and abroad.

The revisions in the Third Edition

of the UV Guidelines refl ect experi-

ence gained from the application of

the guidelines over the years.

The “Protocols” section of the

guidelines was updated to provide a

standardized protocol for conducting

“spot-check” performance of MS-2

based viral bioassays to validate the

installed performance of full-scale UV

disinfection systems. Updates also

standardize the assignment of UV

dose when conducting MS-2 based vi-

ral assays by making use of a standard

MS-2 dose-response relationship.

Key revisions include:

• All reclamation systems must under-

go commissioning tests that dem-

onstrate disinfection performance is

consistent with design intent.

• Velocity profi les have been eliminat-

ed as an option for transferring pilot

data to full-scale facility design.

• On-site MS-2 based viral assays are

used for both the validation and

commissioning test.

• A standard MS-2 dose-response

curve is used to derive the reduction

equivalent dose.

• The design equation is based on the

lower 75-percent prediction interval

for reclamation systems. The lower

90-percent prediction interval is

used for drinking water systems.

• Commissioning tests will require

seven out of eight on-site measure-

ments exceeding the operational

design equation.

• The addition of an appendix to il-

lustrate the computations involved

in the application and evaluation of

UV disinfection systems.

The third edition of the UV Guide-

lines was revised by Robert W. Emer-

ick, Ph.D., P.E., of Stantec Consulting

Services, who was responsible for the

fi rst permitted unfi ltered drinking

water UV disinfection facility in the

U.S. and continues to regularly design

and troubleshoot reclamation-based

UV disinfection systems, and George

Tchobanoglous, Ph.D., P.E., NAE,

Professor Emeritus at the University

of California, Davis, who has authored

or coauthored over 350 publications

on water and wastewater treatment

and solid waste management, includ-

ing 13 textbooks and fi ve engineering

reference books.

Energy costs are a signifi cant part of

utility operating budgets, and a grow-

ing number of utilities today endeavor

to become energy neutral or even net-

energy producers by recovering more

energy from the treatment process

than what they use.

The Water Environment Research

Foundation (WERF) has contracted

with Black & Veatch, in partner-

ship with AECOM, the North East

Biosolids and Residuals Association,

and Hemenway Inc., to explore

energy balance, reduction, recovery

and production opportunities. The

research project – Energy Balance

and Reduction Opportunities, Case

Studies of Energy-Neutral Wastewa-

ter Facilities and Triple Bottom Line

(TBL) Research Planning Support

(ENER1C12) – will help transfer

industry knowledge and experience

among utilities and provide guidance

for achieving energy self-suffi ciency.

Co-sponsored by the New York

State Energy Research and Develop-

ment Authority, the 18-month study

will include participation by 23 utility

partners from the United States and

Australia. The research team will

identify ways for utilities to reduce

demand, increase energy effi ciency,

recover energy and produce energy

onsite by developing baseline energy

fl ows for common wastewater treat-

ment processes.

The team will also document suc-

cesses and obstacles at energy-neutral

or near-net-neutral facilities and iden-

tify sustainable options for managing

biosolids through TBL assessment of

biosolids-to-energy recovery processes

and other biosolids management

practices.

Lori Stone, Biosolids Global Prac-

tice and Technology Leader for Black

& Veatch, and Paul Kohl, Energy

Program Manager at the Philadelphia

Water Department, will lead the team

as co-principal investigators. WW

common. Metropolitan was able to

repair and replace equipment with an

above ground solution quickly and

in the process, improve the operation

and energy effi ciency of the station

by implementing variable frequency

drives for constant pressure control.”

Another new piece of equipment

included in the upgrade was a low-

fl ow shutdown bladder storage tank,

which supports water system leak

loads during low fl ow periods of time.

The pump station was also in-

tegrated into a city-wide SCADA

system for enhanced monitoring and

alarm notifi cation. A fl ood switch was

added to the pump room to provide

notifi cation in the event of a fl ood.

The pumps and valves remain below

ground and are subjected to the haz-

ards associated with such a location.

The upgrades reduced the fre-

quency of confi ned space entry and

improve overall protection of the

equipment.

South Palos Sanitary District

A similar project was completed for

the South Palos Sanitary District of

Palos Park, IL.

“In this project, the municipality

decided to keep their drywell sanitary

lift station pumps below ground, but

implemented new above grade con-

trols into a new prefabricated concrete

building with an exposed aggregate

fi nish,” said Girup.

The prefabricated building contains

the controls and generator. While

the drywell pumps will remain below

ground, the frequency of confi ned

space entry has decreased dramatically

with the implementation of above

ground controls.

Village of Burr Ridge, IL.

The Village of Burr Ridge imple-

mented an above ground traffi c box

to eliminate the frequency of entering

a confi ned space by placing all con-

trols and electrical distribution equip-

ment above ground. The municipality

plans to replace the existing pumps

with submersible pumps in a second

phase.

“In the previous confi guration, the

customer was going down into the pit

quite often to monitor controls, but

with the upgrade, they have to do so

less often,” Girup said.

Conclusion

With each upgrade, the customer

not only gained capital investment

protection by implementing above

grade control systems to protect

controls from potential fl ooding, they

also improved safety conditions by

reducing the frequency of confi ned

space entry. WW

PRODUCT INDEX

Insertion Mag Meter Offers Full Profi le Measurement A new electromagnetic fl ow meter

that will be on display at WEFTEC

combines the accuracy benefi ts of full

profi le measurement with the advan-

tages of an insertion type installation.

McCrometer’s patented FPI Mag™

- Full Profi le Insertion Mag Meter

- spans the entire internal diameter

for pipes from 4” to 138”. Along the

complete sensor length, magnetic coils

are installed internally, with stainless

steel electrode pairs installed exter-

nally. This enables fl ow data collection

from the entire

fl ow diameter and

accuracy up to ±

0.5% from 1 ft/s

to 32 ft/s and up

to ± 1.0% from 0.3

ft/s to 1 ft/s.

The FPI Mag

is precalibrated

by McCrometer

in one of its three

NIST traceable

calibration fa-

cilities. The meter

can be confi gured

for forward only

or bi-directional

measurement. The

single piece, struc-

tural stainless steel

sensor is coated in

a NSF certifi ed,

3M fusion bonded

epoxy coating and

has been rated

IP68 for submers-

ible applications.

All electromag-

netic fl ow meters use

Faraday’s Law of Electromagnetic

Induction. The principle states that a

conductor passing through a magnetic

fi eld induces a voltage. The voltage

magnitude is directly proportional to

the velocity of the conductor. Elec-

tromagnetic fl ow meters create a

magnetic fi eld within the fl ow conduit

and collect the voltage induced by the

fl owing, conductive water. A con-

verter translates the magnitude of the

voltage to an average fl ow rate. The

electromagnetic approach is inherently

reliable and can provide excellent ac-

curacy.

Electromagnetic fl ow meters are

offered in two types, fl anged spool

and insertion. Flanged spool type fl ow

meters are bolted into, and become a

segment of, the fl ow line. The alterna-

tive is the insertion type fl ow meter

which requires only a tap in the pipe

wall through which the sensor can

be inserted. This simplifi ed approach

offers substantial logistical and cost

advantages.

The typical fl ow profi le in pipes is

variable, having been disturbed by

fl ow disruptors such as elbows and

valves. Achieving optimum accuracy

requires collecting data from the full

profi le of the fl ow to account for this

variation. While spool meters are full

fl ow profi le measuring devices, they

can be expensive to procure and com-

plicated to install (pipe cutting, fl ange

welding, heavy equipment, etc.). This

is particularly true for spool meters

used in medium, large and extra-large

pipes.

In many applications, the FPI Mag

can save customers 45%+, when tak-

ing into account both the installation

and meter costs. Other insertion type

meters on the market extend only par-

tially into the fl ow stream, measuring

just the portion to which the sensor

is exposed. An average fl ow rate ex-

trapolated from this limited sample is

subject to error caused by fl ow profi le

variations.

For new water facility designs the

FPI Mag can be installed in short

pipe runs using a dry tap procedure;

this provides greater meter location

fl exibility, smaller plant footprints, less

installation time and lower cost.

For systems needing additional fl ow

meters or an existing meter perfor-

mance upgrade, the meters can often

be installed without shutting down

the line by using a hot tap / wet tap

insertion approach. In the event a

plant operator would ever want to

inspect the meter, it can be easily

removed, leaving the system fl owing

in its absence, without the need for a

surrogate spool.

The municipal market is using the

FPI Mag in raw water, fi lter balanc-

ing and backwash, UV dosing, treated

effl uent, booster stations, distribution

and totalized billing applications. The

industrial market is using it in chilled

water, cooling water, fi re water, feed

water, inlet to surge basins, and clean

effl uent applications. WW

Metering pumps

Walchem and IWAKI America Inc.

have released the new EWN-Y Series

of electromagnetic metering pumps

with an Electromagnetic Flow Sensor

(EFS). The sensor helps a “smart”

pump system accurately control the

pump fl ow rate throughout changing

operating conditions. Set point con-

trol in the pump (through a manual

setting or digital/analog proportional

inputs) sets the desired fl ow rate.

Continuous measurement and feed-

back from the sensor provides actual

output information to the pump,

allowing the pump to self-adjust its

speed and maintain the programmed

fl ow rate. If a reduction in fl ow rate

is sensed, the pump will speed up to

full 360 spm operation, resulting in

a quick re-priming of the pump. The

pump will then slow down back to set

point once fl ow is re-established.Walchem, an Iwaki America Company

general purpose PLC systems, the Flygt APP 800 is specifi cally engineered to

control water and wastewater transport systems. The new system gives customers

a better understanding of the actual cost of their pumping operations by show-

ing the volume of liquid that’s being pumped and the amount of energy being

consumed to pump that liquid. The result is a detailed analysis of kilowatt hours

per million gallons pumped, so customers know where their critical focus should

be to improve energy consumption. Flygt, a Xylem brand

water fi ltration technology to replace

support gravel in the wastewater

market and porous plates in the drink-

ing water sector. The new Leopold

I.M.S® 1000 media retainer allows

wastewater treatment plants to consis-

tently deliver higher quality effl uent

than is possible with support gravel

due to increased media depth and

available driving head. Leopold, a Xylem brand

We’ve heard of the “water energy

nexus” but few recognize its impor-

tance. If the public were fully aware

of its signifi cance, we would see many

more “green” projects than we are

witnessing now. I think full compre-

hension would result in dramatic,

concern-driven actions to address this

critical connection of two incredibly

valuable resources.

On the subject of water supply,

we look at the amount of water in

the world and breathe easy, thinking

enough water is available. To what-

ever degree this may be true, the full

cost to obtain it is not at all obvious.

We have been oblivious to this cost

due largely to government subsidies

masking the true cost of water, and

the true costs to treat wastewater. If

we removed the subsidies and paid the

true costs, our opinions would change

drastically. Water-saving and energy-

saving movements would become

widespread and urgent.

On the wastewater side, the energy

potential contained in wastewater

and its biosolids/biogases exceeds by

10 times the energy used to treat it.

(Source: Water Environment Research

Foundation) Some WWTPs produce

100 percent or more of the energy

they need to operate, and WWTPs

collectively could potentially meet

10 percent of the national electricity

demand. (Source: Water Environment

Research Foundation) This represents

a tremendous opportunity for the

wastewater industry.

In life, we reach points where

something has to change, and this

nexus of (waste)water and energy is

such a point. Our collective ability to

understand the costs and act accord-

ingly will be vital to assuring clean

water supplies well into the future.

I’ve been in the municipal water

and wastewater market for nearly

30 years. It amazes me how little

attention energy use has received

over the thousands of projects I’ve

been involved in. We in this market

understand our involvement in envi-

ronmental protection, so the recent

green movement pleases our psyche.

The implementation of the term

“green” means a lot to our mother

earth and to our children’s children.

Our responsibility is to carry the fl ame

and design away the unnecessary costs

in wastewater treatment with innova-

tive designs, which start mainly with

awareness of energy costs.

I’ve had an opportunity to ask

operators, “How much is your power

bill?” Often times I get blank stares

or replies such as, “That’s the city’s

problem”. The operator’s main re-

sponsibility is safe and effective opera-

tions of their plant and to ensure clean

drinking water or properly processed

wastewater. Energy costs are under-

standably not a priority for them.

But they need to be a priority for the

municipalities and the engineers that

design the plants.

We as environmentalists need to

determine a way we can unite both the

plant function and its energy manage-

ment. I feel that through awareness, ed-

ucation and incremental measures, water

resource management can be improved

and energy use reduced signifi cantly.

Few of us know that thermoelectric

power plants use 41% of our avail-

able fresh water to produce electricity.

(Source: National Energy Technology

Laboratory) Thermoelectric generation

is expected to increase 18% from 2005-

2030, putting even more strain on

water supplies. (Source: Water Manage-

ment in 2010 and Beyond) It’s also not

well known that a thermoelectric power

plant consumes 300—400+ gallons per

megawatt of power generated (Source:

U.S. Department of Energy, 2006 Re-

port to Congress of the Independency

of Energy and Water, Washington

D.C.) and that power plant construc-

tion in some areas is being held up due

to water scarcity. (Source: Energy Law

Journal , Vol. 30:11)

A wastewater plant’s largest energy

consumption is in aeration, by as much

as 60%. (Source: Consortium for

Energy Effi ciency, 2007) This being

the case, it is obvious that plants’ col-

lective energy costs across the country

will continue to rise with the increase

in treated volumes. Thus, the crisis of

the water energy nexus: that growing

power production places greater strains

on water supplies and more wastewater

treatment consumes more energy.

WWTP effl uent has been success-

fully used as cooling water for power

plants. It’s also known that 81% of

power plants proposed for construc-

tion have one or two WWTPs within

a 10-mile radius, and those plants

could provide a suffi cient cooling

water supply. Further, 97% could

meet their cooling needs with one to

two WWTPs within 25 mile radius.

(Source: U.S. DOE Study, Reuse of

Treated Internal or External Wastewa-

ters in the Cooling Systems of Coal-

Based Thermoelectric Power Plants)

With awareness and knowledge of

the facts, municipalities can look to

site WWTPs near existing or proposed

power plants, with the potential to

sell the clean effl uent to the plants

for cooling water. Biosolids and/or

biogases can be recovered and sold

to those same plants as fuel. Or they

could be used on site to generate pow-

er to run the WWTP. New separation

technologies are capable of extracting

phosphates from the waste stream,

which can be sold to manufacturers.

It’s also possible that power plants

could own and operate adjacently sited

WWTPs, gaining direct access to water

& fuel outputs while also relieving cit-

ies of the capital expense of building a

plant. The options are numerous.

There are also many options for

reducing energy usage within a plant.

Whether it be simple awareness,

replacing older equipment with more

energy effi cient units, or modifying

on-off cycling of equipment, sav-

ings can be signifi cant. Benefi ts from

investing in energy savings can come

from Federal and State assistance pro-

grams or simply the savings on a treat-

ment plant’s power bill, all without

impacting the treatment quality.

Energy and water are tightly con-

nected, and WWTPs are at the heart

of that nexus. Awareness of that

relationship is the starting point. We

must innovate by moving toward

zero discharge facilities, where zero

discharge for this purpose means

completely recycling/reusing a plant’s

outputs. We must educate plant

personnel on energy usage; improve

process operations; and lower a plant’s

carbon footprint.

Through all of this, our country’s

WWTPs can do much more than just

save energy, they can actually become

cash cows from the tremendous ener-

gy potential contained in wastewater.

It’s imperative that we move forward

on this process. WW

St. Bernard Parish is situated south-

east of New Orleans in the state of

Louisiana. In 2000, its population was

67,229 and expansion was underway.

Today it is only half as populated as

it was in 2000 due to the evacuation

and outmigration as a result of the

destruction by hurricane Katrina in

2005.

In the summer of 2008 the Par-

ish’s Sewer & Water Division started

to notice a drop in water quality

from their quarterly water samples

which are required by the Depart-

ment of Health. They also started to

get complaints from residents saying

that there was a chemical taste in the

water and it looked rusty and yellow

and sometimes had a septic smell to

it. In further testing by the Depart-

ment of Health they also found that

the ammonia build up was higher than

normal.

Jacob Groby, Superintendent of

Quality Control for the Parish, met

with the Federal Emergency Manage-

ment Agency (FEMA) and explained

that the poor water quality was due to

transformations in the distribution

system and the storage tanks.

“Our water quality was being

affected by loss of physical integrity

such as contaminant intrusion due

to breaks, repairs and lower than

normal fl ows, which was causing us

to show lower than normal chlorine

levels, higher than normal nitrate

levels and elevated bio-fi lm growth in

our distribution system,” Groby said.

Hurricane Katrina had not only

caused damage to the system, but

the loss of population meant low

usage, which lead to low velocities

that resulted in the accumulation of

ammonia and other sediments. There

was simply not enough population to

use the water they were producing.

In the Murphy Buy Out zone, usage

had dropped from 180 + homes to

a mere 35. Without a

formal fl ushing program,

nitrifi cation was taking

place more now than

ever.

To make matters worse,

the Department of Health

and Hospitals informed St

Bernard Parish in March

of 2010 that they were in

danger of being in non-

compliance with water

quality regulations and

were now required to sub-

mit for Initial Distribution

System Evaluation (IDSE)

monitoring.

St Bernard Parish

needed a pro-active fl ush-

ing system solution and

contacted Todd Burnett,

President of Coastal

Process, LLC, to fi nd a

suitable system.

The Singer Valve Total

Automatic Purging System

(TAPS) was chosen for its

heavy duty design, AWWA

valve compliance and its

ease of programming, Bur-

nett said. The compact size

was also an advantage for

handling and installation.

While there are a vari-

ety of different valve sizes,

St. Bernard parish used the 40mm

(1.1/2”) valve which optimizes the

fl ushing process for their pipe size

as it provides the correct velocity to

pull fresh water into each zone. This,

coupled with the pressure sustaining

feature, scours and cleans the pipes

which reduces corrosion and has dra-

matically improved water quality.

The installation process was a two-

fold operation. In order to reduce the

physical appearance of an industrial

device in front of someone’s home,

the parish purchased a valve box to

protect and conceal the fl ushing unit.

Each location has a custom poured

slab with the discharge tied directly

into the subsurface drainage system so

as not to cause unsightly or hazard-

ous conditions. Each TAPS unit

includes a water sampling port so that

onsite clarity and testing can be seen

and sampled without disrupting the

process.

Once the 50 units were installed, it

took three days to program them all.

“The programming was easy, the

hard part for us was deciding how to

set them so that we could use them

in the best manner possible,” Groby

said.

Parish staff designed the fl ush cycle

to create a weekly wave action to force

fl ush 27 miles of the distribution sys-

tem. With regulated fl ush cycles and

perfected velocity at each individual

installation point, fresh water is ef-

fectively drawn into areas where water

quality was falling below standard. In

addition, staff decided to start fl ushing

from every dead-end in the system,

which ensured the removal of poor

water.

The programming allows the Parish

to activate fl ushing at any given time

of the day or week. The best time to

do this is at night when demand is

low. This also prevents cloudy water,

low pressure and standing water

complaints that are associated with

conventional high volume, daytime

fl ushing activities. This also enables

distribution of the discharged water

over several hours, if necessary, by

programming the units to activate for

shorter multiple durations throughout

any given day.

TAPS also has a unique pressure

sustaining feature to ensure minimum

upstream pressure is maintained for

system needs and in the event that fi re

fl ow is needed.

“Unlike conventional fl ushing

valves that are either open or closed,

TAPS has a hydraulically operated

valve that introduces or releases water

from the control chamber above the

diaphragm to maintain accurate water

fl ow,” said Mark Gimson, Business

Development & Marketing Manager

for Singer Valve.

St Bernard Parish is now on track

with water quality standards and

regulations.

“Our distribution system has shown

a marked improvement on most fac-

tors with improved chlorine residu-

als, lower total Trihalomethane and

Haloacetic acid values, plus reduced

consumer complaints,” Groby said.WW


Automatic Purging System Helps Parish Comply with Water Safety

TAPS is compact and the discharge can be tied directly into the subsurface drainage system.
