pOsItIOn and the GrOWth Of uf and mf teChnOLOGy.

Though low-pressure MF and UF membranes have been available

for 80 years, it has only been in the last 20 years that they have

made serious inroads into the market. GWI’s conclusion is that

today, by some measures, the technology has overtaken reverse

osmosis in terms of popularity. The MF/UF market developed in

three key stages. The first stage was the spread of MF and UF for

drinking water treatment in the US following the 1993

Cryptosporidium outbreak in Milwaukee. The next stage was the

emergence of low-pressure membranes as a wastewater treatment

solution during the late 1990s and early

2000s, reflecting growing interest in water

reuse, and the smaller plant footprints

offered by the membrane bioreactor for-

mat. The third stage of market develop-

ment came in the mid-2000s when the

potential for low-pressure membranes as

a seawater pre-treatment method for

reverse osmosis was realized.

The GWI research shows that the Americas

accounted for the largest market share

until 2008. Since then, the Asia Pacific and

EMEA (Europe, Middle East and Africa)

markets each outgrew the Americas main-

ly due to strong growth in the market

for desalination pre-treatment and the

continuing strength of the wastewater

treatment sector. This has changed the

competitive dynamics of the sector, much

of it in favor of Pentair X-Flow.

Two key elements are believed to be at

the basis of this market success: First,

Pentair X-Flow has launched several

unique solutions into high growth market

segments including:

SEAGUARD, the industry’s first

dedicated seawater pre-treatment

membrane module

Pentair Airlift™ MBR Megablock, a

direct sludge filtration system that

represents the most cost, space and

quality effective solution to meet

stringent wastewater treatment

directives and produce effluent with

a quality suited for water reuse

applications.

Secondly, Pentair X-Flow maintains a dual

market strategy of both directly executing

projects, primarily in Western Europe, and

being a premier membrane technology

and service supplier to a network of

design engineers and engineering, pro-

curement and construction (EPC) contrac-

tors on the other hand.

The first is crucial in order to have direct

experience in key application segments

that feed the company’s R&D agenda and

integrates our vast knowledge base.

Pentair X-Flow then uses this know-how

to support our worldwide EPC contrac-

tors with state-of-the-art membrane

technology and application expertise.

ultrafiltration is an effective barrier for microbialsprotection at the tap

FRAnK vAn Heusden what’s in your water?

Water is used from kitchen and bathroom taps

every day, but is the water really as safe, healthy

and great tasting as it could be? Unless the water

is filtered immediately before use with an

advanced technology like ultrafiltration (UF)

membranes there is no way to know for sure.

Whether a home is on city or well water, harmful

or undesirable contaminants could be flowing

from faucets every day that you cannot see or

taste. Unfortunately, throughout the world even

with stringent national and local regulations, and

due diligence by water utilities, microbiological

contamination in water supplies is a reality. Old

and deteriorating water pipes and city water

main breaks can contaminate water before it

reaches a home. Private wells can become

contaminated at any time. Without constant

self-monitoring of a well, there is no way to

know when this happens. Due to the increased

publicity consumers worldwide realize the need

to be more vigilant about the quality of water

they are consuming.

The Water Quality Association’s leadership is

working to encourage U.S. officials to understand

that the most practical solution to water related

issues is to integrate point-of-use (POU) into the

current regulatory paradigm. “Our goal is to

advance the understanding of policy makers

about final barrier treatment of drinking,” said

Peter Censky, executive director of WQA. “We

begin with a premise that within 20 years the

current paradigm – centrally treating water and

doing essentially nothing more – will no longer

work. Central treatment will not be able to cope

with the demand for higher quality water.”

Certified purification you can rely on

Pentair’s H2OK WaterPurifiers, which use Pentair

X-Flow UF membrane technology, are one of the

few POU drinking water products available in the

world certified by the Water Quality Association

(WQA) to retain 99.99 percent of viruses and cysts

and 99.9999 percent of bacteria. They carry the

WQA Gold Seal certification to both the US EPA

Standard for Microbiological Water Purifiers and

NSF P231.

“Ultrafiltration membranes are hollow fiber

straw-like structures with walls that consist of

billions of microscopic pores that are smaller

than viruses, bacteria, protozoa, and fungi,” said

Anton van de Ven, Commercial Director at Pentair

Filtrix. “They are the ideal barrier for microbio-

logical outbreaks, which is why they were chosen

for use in our WaterPurifiers.”

Pentair H2OK WaterPurifiers work on normal line

pressure, use no energy, do not generate any

wastewater in the filtering process, retain vital

minerals, and do not alter the taste of the water.

Membrane filters will block microbes up to the

expiration date making sure no contamination

can ever come through.

Clean, safe and easy

The easiest and most economical way to ensure

safe drinking water is to filter it at the tap. When

choosing an in-home water treatment system, it

is important to know that all POU filtration

products are not the same. To ensure the safest,

highest quality water possible, you should choose

a filter that is certified to protect against viruses,

cysts and bacteria, and removes chemical

contaminants while delivering great-tasting,

odor-free water The Pentair WaterPurifier+ that

combines UF membranes and activated carbon

provides this complete protection.

“Pentair H2OK WaterPurifiers are well positioned

against other POU technologies on the market,”

van de Ven said. “Overall, UF is an excellent and

sustainable way to eliminate the uncertainty of

microbiological outbreaks and ensure consistent

delivery of high-quality water, without electricity

or wasted water that other technologies require.”

Pentair Process Technology will install a turnkey state-

of-the-art beer filtration installation that includes one

BMF-18 skid with a possible second BMF skid in the

future. The brewery is integrating the expansion

into the existing filter room. The completion of the

project is scheduled for fall 2011.

Started in 1605 as a family business, Ustersbach is now

a renowned brewery with a diverse product line. The

brewery produces nine different beers including pils-

ner, pale beer, wheat beer, and strong beer, along

with a selection of soft drinks. All beers use mainly

local products, without pasteurization and in the

tradition relating to crafts following the Bavarian

purity requirement of 1516.

“The diatomaceous earth-free beer filtration is

gaining ground in the beer industry and we are

convinced that Pentair’s BMF system is in line

with our ambition to produce beer of the high-

est quality according to our family recipes while

using modern, efficient and environment-

friendly techniques,” said Stephanie Schmid,

owner of brewery Ustersbach.

Dick Meijer, Pentair Process Technology’s

Commercial Director - Beverage, added, “This

illustrates our capacity to pre-

pare breweries of all sizes for

Guinness Anchor Berhad (GAB) was founded in 1964 originally under the name “Guinness Malaysia Limited”. In 1966, the company changed its name to “Guinness Malaysia Berhad”, and in 1989, the name was again changed to GAB that it operates under today. GAB is the product of a fusion between Guinness Malaysia Berhad and Malayan Breweries (Malaya) Sdn Bhd (“MBM”), each of which are subsidiaries of Guinness Overseas Ltd and Malayan Breweries Ltd, respec-tively. The latter operates under the name Asia Pacific Breweries Limited (“APB”), based in Singapore.

GAB operates the Sungei Way Brewery in Malaysia, which was commissioned in 1965. The brewery is located in the city of Petaling Jaya in the state of Selangor, where it produces Tiger, Guinness, Heineken, Anchor Smooth, Anchor Strong, Kilkenny, Anglia Shandy, and Malta. The plant’s capacity is approximately one million hectoliter per year. GAB occupies the leading position in the Malaysian beer market with a market share of approximately 57 percent.

either Apb or GuinnessThe Sungei Way Brewery is the only one of its kind in the world. It consists of two production lines, completely separate from one another, in which only APB or only Guinness beers are brewed. The maxim here is: The products are not

allowed to be mixed, not even the gases liberated from fermentation. Consequently, the brewery has two separate CO2 systems in opera-tion that were both supplied by Pentair Haffmans approximately 20 years ago.

Chuah Chong Sheng, project engineer for the CO2 supply at GAB, shares his reflections on the past. “We simply weren’t able to produce enough of our own CO2 with the existing systems,” he said. “Each month, we had to purchase supple-mental CO2, which is complicated and expensive. Also, the refrigerant R22 was still used in this system, which is less than ideal from an environ-mental perspective.”

“we were immediately won over by this concept”In order to find an optimal solution for this problem, the brewery contacted Pentair Haffmans. Initially, several completely different concepts were developed and their respective advantages evaluated. Replacement with a new plant would have brought the highest efficiency, supplying both brewing plants at a rate of 1,000 kg/h simultaneously. However, this could not be implemented at the time due to certain aspects of the brewery’s strategic planning. Instead, the decision was made to retrofit the existing 500 kg/h systems with the alternative presented by the innovative unit known as the LiquiVap.

double duty Guinness Anchor berhad: Retrofitting with liquivap increases Co2 recovery yield and lowers costs

“We have not had to purchase any more CO2 and are operating more sustainably, as we now use less electricity.”

Chuah Chong sheng, project engineer at GAb and responsible for the Co2 supply, is completely satisfied with the results of retrofitting with the liquivap.

7K n o w H o w i 2 0 1 1 i 1

“This idea was very convincing, since the existing plants were also manufactured by Pentair Haffmans,” Chuah Chong Sheng recalled. “We were already familiar with the products they are capable of delivering and also the high level of service from Pentair Haffmans. Furthermore, we already have a LiquiVap unit at APB in Singapore, providing us with a means for comparison. It has been in operation there for more than a year.”

evaporating Co2 cools fermentation gasLiquiVap – a term created from abbreviations for liquefaction and evaporation – is an energy saving system for CO2 recovery plants. During recovery, the gaseous CO2 must be cooled and liquefied prior to storage in tanks at a temperature of -24 °C and a pressure of 18 bar. In order to be able to utilize this stored liquid CO2 in the brewing pro-cess, the liquid CO2 is heated with air or steam and evaporated.

This “energy of evaporation” can be captured very efficiently from this process with the LiquiVap system. As the CO2 evaporates, it liquefies the gaseous carbon dioxide coming from the activat-ed carbon filters and dryers. In this manner, the energy is recovered that would otherwise be elec-trically fed into the refrigeration system. Additionally, the cooling capacities required of the refrigeration systems are significantly lower. When undertaking the expansion of a CO2 recov-ery system’s overall capacity, one can forego a complete expansion of the refrigeration system’s capacity in favor of installing a LiquiVap unit.

If less energy is required for cooling, this directly results in lower total costs associated with CO2. Yet another advantage of the LiquiVap is that it does not contain any mechanical parts, making continuous operation possible over long periods without interruptions for maintenance. Reducing the hours of operation of an existing refrigeration

system as well as its maintenance costs are cer-tainly not the least of these advantages, which also include increased reliability.

optimal energy efficiency all of the timeHowever, with LiquiVap the amount of cooling that takes place directly corresponds to the amount of evaporation. To integrate it into real-world applications, system operation is impor-tant. During the cooling stage to assure opera-tions are within the most optimal range, the cooling capacity needs to adjust to production variables. For example, if the system is dimen-sioned for 500 kg/h but production only requires 400 kg/h, then only 400 kg/h can be cooled using the LiquiVap. Separate cooling capacity is required for the remaining 100 kg/h must be cooled by the existing refrigeration system. But, it is essential to understand that the control system precisely regulates the refrigeration process so that the energy required to cool the 100 kg/h is consumed – no more and no less. In this manner, energy efficiency always remains at an optimal level.

Four percent makes a differenceAt the GAB Brewery, in addition to retrofitting

double duty with a LiquiVap unit and the installation of the latest control system, the entire final stage of CO2 treatment was redesigned. The previously employed means for cooling the CO2, in which the less desirable refrigerant was used, was replaced and modernized with one designed to meet future environmental requirements. Using the innovative LiquiVap system, very low process temperatures are possible. As a result, gas at an initial purity of 95 percent can be recovered, compared to the situation before retrofitting, in which it was only feasible with gas at an initial purity of 99 percent. The difference of four per-cent means that the fermenters can be connect-ed earlier, and, therefore, a greater volume of CO2 can be recovered. “For over a year, both of our plants have proven their value under the challenging production conditions we experi-ence on a daily basis,” Chuah Chong Sheng explained in summarizing this successful project. “Since commissioning these units, we have indeed become self-sufficient and have not had to purchase any CO2 – not to mention that we have achieved this in conjunction with savings through utilizing sustainable energy as well. We are completely satisfied with all aspects of retro-fitting with the LiquiVap.”

The recovered CO2 (green line) is lique-fied in the LiquiVap unit through the evaporation of liquid CO2 (blue line) – energy savings in both the cooling and heating stages of the process are the result.

Pentair Water Asia Pacific will supply Pentair

X-Flow’s XIGA ultrafiltration (UF) membranes to

the Lower Seletar Waterworks project in

Singapore to be constructed by Sembawang

Engineers and Constructors (Sembawang), one of

the leading engineering and construction compa-

nies in Southeast Asia.

Once constructed, with a capacity to process 300 MLD

of raw water into drinking water, the Lower Seletar

Waterworks will be one of the largest drinking water

plants in Singapore that utilizes UF at the front of its

treatment process. It is also the first drinking water

plant in Singapore to use a pressurized UF membrane

system.

Pentair X-Flow XIGA UF membranes are widely used

throughout the world for large-scale drinking water

production and effluent reuse. They are horizontally

mounted membranes housed in pressure vessels.

The pressure vessels are stacked on a skid to reduce the

footprint, which makes Pentair X-Flow’s XIGA UF mem-

brane system well suited for the Lower Seletar plant’s

limited footprint. In addition, the absolute pore size of

XIGA membranes ranges from 0.025 to 0.030 microns

making XIGA one of the tightest in its class. This enables

high log removal for both bacteria and viruses.

“The use of XIGA membranes for drinking water

production could potentially reduce the cost of

downstream disinfection and provide cost savings for

the end-user,” explained Duane Schlicht, Managing

Director Pentair Water Asia Pacific.

XIGA™ - the membrane of choice around the globe

A three-phase project in Gothenburg, Sweden to

increase production capabilities of purifying sur-

face water to drinking water will use Pentair

X-Flow’s ultrafiltration (UF) technology.

Gothenburg, the second largest city in the coun-

try, is located on the west coast of Sweden. The

city’s water treatment facility must supply approx-

imately 500,000 consumers with drinking water

using surface water and river water from the Göta

älv (Gota River).

The three phases of the project will increase

water production to meet demand and high qual-

ity standards. Phase one will produce 1,800 m3/h

by 2013, Phase two, 3,600 m3/h in 2015, and Phase

three, 7,000 m3/h in 2017. In the first phase of the

project, a UF plant with four Pentair X-Flow skids,

each equipped with 36 pressure vessels containing

XIGA UF membranes, will be installed in an exist-

ing water production plant. By the end of Phase

three, 16 skids will be installed. Pentair X-Flow has

partnered with Purac, a prestigious Swedish con-

tracting firm, for this project.

In the treatment process surface water is coagu-

lated and, after settling, sent through granular

activated carbon filters. The output of the carbon

filters is transferred through the UF membrane

system.

Singapore is a land-scarce country

with limited water resources. As such,

the nation has long recognized the importance of

developing and maximizing its water resources to

sustain its economic growth and modern lifestyle

of its citizens. PUB, the nation’s water authority,

has initiated many internationally renowned proj-

ects including NEWater factories, the Tuas desali-

nation plant and the Marina Barrage (for urban

water collection). With its aim of becoming one of

the world’s hydro hubs, Singapore always wel-

comes and embraces the use of advanced water

purification technology in its quest to increase the

nation’s water supply and improve its water secu-

rity. The selection of Pentair X-Flow’s XIGA UF

membranes for drinking water production at the

Lower Seletar plant bears further testament to

the high quality and reliability of Pentair X-Flow

membrane products.

The UAE depends on desalination to

supply water. By focusing on waste-

water reuse, the UAE is responding to the need to

ensure security for its long-term water supply. In

2010, Abu Dhabi introduced new wastewater

regulations, and by doing so the Emirate estab-

lished itself as the regional leader in the water

reuse sector.

In addition to the ultrafiltration (UF) polishing of

the TSE, the plant includes a strainer and ultra-

violet protection processes. An estimated 95 per-

cent of the TSE supplied to the plant will be

recycled and recovered. This water is used for

agricultural irrigation and horizontal land-

scaping.

The Al Wathba TSE polishing plant is important in

setting the trend in the UAE for wastewater treat-

ment using UF membranes for tertiary filtration

of treated sewage. This technology provides a

credible and proven alternative to the desalina-

tion of seawater for non-potable applications. By

supplying UF technology to the ADSSC’s Al

Wathba plant, Pentair X-Flow reinforces its posi-

tion as the UF market leader in the Middle East.

Pentair Südmo engineers are constantly look-

ing for ways that help our customers ‘do

more with less’. The most recent technologi-

cal breakthrough, the 365it Complete, based

on the DSV Complete Valve, uses a standard

housing without increasing the size of the

leakage outlet port. Up to now, this was

necessary to avoid pressure build up in the

leakage area. The addition of this advantage

reduces the valve’s weight and building space

requirement, and provides easier handling

and maintenance.

Pentair Südmo’s patented deflector techno-

logy upgrades a standard DSV Complete Valve

to the 365it Complete. The deflector guides

CIP fluid directly into the leakage outlet

during seat lifting and creates a vacuum just

in front of the opposite side seal thus avoid-

ing direct impingement of the opposite seal.

With the 365it Complete Valve and the

reduced size of the leakage port, dairy plants

will experience OPEX savings due to less clean-

ing media loss during seat lifting while main-

taining maximum product safety. During daily

operations, the new radial seal compensates

for swelling, which reduces wear and provides

an extremely robust and long life resulting in

even greater life cycle cost savings.

the Pasteurized Milk Ordinance (PMO), which means

that with 3-A approval double seat/mix proof valves,

the valve can be used in U.S. dairy plants.

Firefighting pump room protects

gas and oil plant

“One pump room was installed for the end cus-

tomer OMV Petrom S.A. at its new gas compres-

sor station in Bulbuceni, Romania,” said Niels

van den Hurk, Pentair Nijhuis’ area sales mana-

ger. “Petrom is the largest corporation in

Romania and the largest gas and oil producer in

Eastern Europe. From Bulbuceni, Petrom provides

compressed gas to the national gas network.”

The pump room in Bulbuceni needed to meet

Petrom’s safety requirements and strict sound reduc-

tion demands to protect personnel and the work

area. Since the equipment is tested weekly, part of

meeting these guidelines included insulating the

pump room so that the sound level from one meter

measures less than 85 dBA.

In addition to the customer’s requirements, a num-

ber of extreme conditions that are decisive factors

for selecting the proper diesel engine were taken

into account for the pump room design. These

conditions are: the site is located at 208 meters

(682 feet) above sea level, the surroundings tem-

perature varies between minus 29 and 40 degrees

Celsius (minus 20 and 104 degrees Fahrenheit) and

the average relative humidity is 63 percent. The

pump room, consisting of four pumps and two

jockey pumps –that serve to maintain water pres-

sure in the sprinkler system–, provides the com-

plete water supply for fire protection at this loca-

tion.

“The pump room was designed according to the lat-

est directives of the National Fire Protection

Association’s (NFPA) international standard NFPA-

20,” van den Hurk said. “Besides that I am proud to

say that we were able to meet all extra require-

ments, even though the conditions were challeng-

ing.”

new power plant in venezuela protected against fire

The end customer of the second pump room, C.A.

Energía Eléctrica de Venezuela (Enelven), built two

combined cycle power plants in Zulia state, Venezuela.

These power plants will supply sufficient energy to

meet the energy demand of the entire region.

“The EPCC of this project, Ferrostaal, initially contact-

ed Pentair Nijhuis to supply separate firefighting

pumps at the location in Bachaquero,” van den Hurk

said. “But, considering the remote location, they

chose the containerized pump room option, and thus

profit from the advantages of this solution.”

The pump room contains two firefighting pumps, one

diesel driven, one electric driven pump, and one

jockey pump. All pumps comply with the latest regula-

tions of NFPA-20, and are Factory Mutual (FM)

approved. In addition, extra devices, supplied by the

customer, were successfully incorporated into the total

containerized concept.

“Constructing containerized units requires expertise

that is available within Pentair Nijhuis,” van den Hurk

said. “The firefighting equipment at both Petrom and

Enelven well prepares both locations in the event of a

fire. Studies have shown that when such units are in

place, fire damage will be restricted to less than

10 percent, thus providing lower costs and less envi-

ronmental impact.”

On deCember 9, 2010.

Pentair Nijhuis is member of a pilot group of organizations that have

started the implementation of this NEN directive. During the intro-

duction seminar on December 9, practical experiences with the appli-

cation of ISO 26000 in business and industry were presented. Pentair

Nijhuis’ Managing Director Robert Schuuring was one of the speakers.

“ISO 26000 is well suited to Pentair Nijhuis,” he said. “Our products

represent quality, high efficiency and durability. We use ISO 26000 as

a guide to integrate social responsibility into our values and practices.

We are taking an even more critical look at our purchase and produc-

tion processes and the social environment. ISO 26000 presents a very

good approach in doing so.”

ISO 26000 is a guidance standard and is

not for certification. It offers structure

to organizations for implementing SR.

The directive concerns SR core subjects

including organizational governance,

environment, fair operating practices,

community involvement, human rights,

labor issues, and consumer/customer

issues.

“NEN is soon publishing a book with

practical experiences of ISO 26000

champions, and Pentair Nijhuis is one

of them,” Schuuring added. “Together

with nine other companies, we were

the first Dutch company to implement

this directive. Our successes and learn-

ing points will help other companies

with their corporate social responsibil-

ity challenge.”

This biogas upgrading plant is the first of its kind. Pentair

Haffmans installed the plant at Bouwhuis Biovergisting BV in

Witteveen in November 2010. Bouwhuis is an agricultural com-

pany that produces biogas from corn.

The company expanded the capacity of its two running combined

heat and power (CHP) installations. The additional 350 Nm3/h

biogas are upgraded by Pentair Haffmans into 215 Nm3/h bio-

methane and 250 kg/h purified carbon dioxide (CO2).

“This a great step for Pentair Haffmans and

fits perfectly into the shift towards renewable

energy sources,” said Olaf Müller, Managing

Director Pentair Haffmans, Head of Beverage

and Niche Markets - Pentair Clean Process

Technologies. “The energy targets of the

European Union state that in 2020 20 percent

of the energy used should come from alterna-

tive energy sources.”

Biogas is a general term for gas produced

through an anaerobic fermentation process

and primarily consists of a mixture of methane

(CH4) and CO2. The upgrading technology

recovers 100 percent of the CH4 and causes no

CH4 losses. In the process the biogas is first

cleaned by a Norit activated carbon filter and

then the cleaned biogas flows through a mem-

brane installation and a CO2 recovery system.

The biomethane produced by the upgrading

system has the same specifications as natural

gas and has been accepted by Enexis for inject-

ing it into the national gas grid. Enexis is

responsible for the development, construc-

tion, maintenance and management of the

gas and energy distribution network. As such

the company is the link between 2.6 million

customers and the energy suppliers.

The recovered CO2 has a high purity and can

be used as CO2 gas in greenhouses or liquefied

and stored for use in the food and beverage

industries.

biogas upgrading installation reaches first milestone!

The iF Product Design Awards are prestigious awards that recog-

nize manufacturers and designers of industrial products exhibit-

ing superior design from around the world in a variety of

categories. Selection criteria include the quality of design, func-

tionality, degree of innovation, simplicity of operation, and

environmental impact. The Pentair Megablock is used in muni-

cipal wastewater treatment.

Specifically it is the sludge separating component of large-scale Membrane

BioReactor (MBR) systems. The compact membrane separation system within

the Megablock produces crystal-clear, bacteria-free water from a biological

wastewater treatment process that can be reused for a variety of purposes.

In addition, the membranes are in a dry and clean environment making

them quickly accessible without comprising the health and safety of plant

workers.

iF praised the Megablock for its “Lego™-Style” modular design that allows

for easy installation and system expansion. Its advanced component design

improves fluid flow and aeration, resulting in unprecedented performance.

“The Efficient Performance Technology philosophy - our guiding principle in

product development - led to the Megablock’s development,” said Rick

Rosberg, Global Commercial Director of Pentair X-Flow. “A compact, modu-

lar design flows naturally from our ambition to do more with less.”

Prompt action by the Pentair Nijhuis

service team prevented a major disrup-

tion at the Dolfinarium, a dolphin

theme park in Münster, Germany. Two

pump rooms at the facility were flood-

ed due to a water pipe leak. The leak

was repaired and the pump rooms

were drained, but the pumps needed

to be repaired and restarted to main-

tain the water in the pool where the

dolphins and other sea animals live.

This had to be done quickly to avoid

the need to move the animals 300 km

to the Dolfinarium in Harderwijk, the

Netherlands. Thanks to Pentair Nijhuis’

experienced service team the pumps

were started up in time and the move

was not necessary. A well earned

“thank you” was the result.
