PREDESIGN REPORT
1 Introduction
1.1 Background
The Town of Lumsden is a community of approximately 1700 people situated next to the
Qu'Appelle River in southern Saskatchewan. The Saskatchewan Ministry of Environment (MOE)
has imposed development restrictions on the Town until it upgrades its existing lagoon wastewater
treatment system which is operating beyond capacity. The Town has identified a new mechanical
wastewater treatment facility (WWTF) as the long term solution. Associated Engineering (AE)
completed the preliminary design of a WWTF in December 2011 and the Town hopes to proceed
with detailed design and construction so that the facility is in operation in 2015. In order to allow
land development to proceed in the interim before the WWTF is operational, the Town of Lumsden requires a short term wastewater strategy.
1.2 Project Understanding
Local developers are planning to construct homes immediately upon regulatory approval.
Depending upon housing demand, housing starts could approach 100 houses by 2014.
The MOE has required that the Town offset extra volumetric and organic loading from new
construction . To offset volumetric loading, the Town plans to implement bylaws requiring the use of
low flow toilets, faucets and showerheads and sump pumps to discharge weeping tile flows to the
surface in new homes. Existing households' toilets will be required to be upgraded to low flow
toilets. The toilet replacements will offset the volumetric loading into the lagoon facility.
The Town of Lumsden has retained AE to develop short term solutions to offset organic loading.
This preliminary design report evaluates chemical and physical treatment methods for oxidizing the
excessive organic loading at the existing lagoons. The methods are evaluated based on lifecycle
costs and the most suitable method is recommended as the preferred short term wastewater management strategy.
2 Chemical Treatment
2.1 Chemical Requirements
According to "Guidelines for Sewage Works Design (January 2008)" a typical BODs for raw sewage
from domestic sources is 77 grams/capita-day. A value of 2 .6 people per household, based on the
Lumsden Community Profile from the 2006 Canada Census, is used to determine chemical
requirements.
The BODs generated for a lot is equal to 77 grams/capita-day multiplied by the population of 2.6
people. This equals 200 grams of BODs per day.

Predesign Report Short Term Wastewater Management Strategy
Usually the quantity of chemical which is added to a liquid is measured in parts per million (ppm).
In water based liquids 1 mg/L is equal to 1 ppm because 1 liter of water has a mass of 1 kg. In order to neutralize 1 mg/L BOD, 1 mg/L or 1 ppm of 0 2 is required. To determine the dosage of
chemicals, generation of 0 2 or equivalent oxidation potential in the reaction is considered .
2.2 Chemical Characteristics
Numerous oxidizing chemicals have been used in the wastewater industry. The six chemicals
identified and discussed are commonly used in water and wastewater treatment plants. The two
most relevant to the current project are discussed in more detail.
From an operational point of view, dosing chemicals in solid form is more costly and operator
intensive. However, dosing chemicals in a liquid form is simpler and can be easily automated. A chemical in a liquid form is more desirable because it can be dosed with chemical pumps which
operate more predictably and require less operator attention.
2.2.1 Sodium Hypochlorite (NaOCI)
Sodium hypochlorite is used for shock chlorination of wells and water systems. The
alkalinity of the sodium hypochlorite solution also causes the precipitation of minerals such as calcium carbonate. Sodium hypochlorite is commonly used for disinfection of drinking
water. The use of chlorine-based disinfectants in domestic water is believed to result in formation of small quantities of harmful by-products such as trihalomethanes (THMs).
Sodium hypochlorite is also used to treat cyanide in wastewater. The main problems with
sodium hypochlorite are the production of harmful by-products and high alkalinity. The pH
is 7.6 in the Lumsden lagoon treatment system. Adding sodium hypochlorite will increase
the pH which is harmful to the microorganisms.
Sodium percarbonate is used for shock treatment in non-chlorine swimming pools. Sodium
percarbonate is a strong oxidizing agent. It is supplied in a solid form and dissolves in
water yielding a mixture of hydrogen peroxide, which eventually decomposes to water and
oxygen, and sodium carbonate. Released oxygen is available for use by microorganisms
to oxidize the organic matter. The main issue with this chemical is that only a small portion
of the chemical is beneficial. The larger portion of sodium percarbonate is sodium
carbonate. A better alternative to this chemical is hydrogen peroxide which comes in a liquid form and does not include the unnecessary sodium carbonate.
2.2.3 Potassium Permanganate (KMn04)
Potassium permanganate is used extensively in the water treatment industry. It is also
used as a regeneration chemical to remove iron and hydrogen sulfide (which creates a
rotten egg smell) from well water when used in conjunction with a manganese greensand
2 P:\2011 4865100 _Lumsden_ Con_ Study\Engineering\03.02 _ Conceptuat_Feasibility_Report\Final Report\rpt_ short_ term_ 20120131 .doc
Predesign Report Short Term Wastewater Management Strategy
filter. Also as an oxidant, potassium permanganate can act as an antiseptic. The main
reason for using a chemical in this project is to remove organic loading. Potassium
permanganate is not suitable for this project since it does not provide dissolved oxygen
(DO) and will kill microorganisms.
2.2.4 Sodium Nitrate (NaN03)
Sodium nitrate is used in the wastewater industry to increase the number of facultative
microorganisms. These microorganisms consume nitrate in preference to oxygen,
therefore more oxygen is available to oxidize organic material.
Sodium nitrate has been used to address odour issues in both City of Weyburn and Town
of Lumsden. This chemical is added to lagoons to maintain the aerobic condition of the
lagoon (Munoz et. al, 2008). This chemical is added in a large enough amount to shock
the system which temporarily addresses the odour issues.
Sodium nitrate indirectly addresses the organic loading problem since it does not break
down the organic waste itself, but rather provides nitrate to microorganisms, increasing
their population and the rate at which they neutralize waste. Also, sodium nitrate forms nitrosamines, a human carcinogen known to cause DNA damage and increased cellular
degeneration. Sodium nitrate also comes in a solid form.
2.2.5 Oxy Sparkle (Oxone®)
Oxy Sparkle, marketed by Canadian Tire, is a product for pool cleaning which contains
peroxysulfate. It is similar to a US product called Oxy-Brite, also used for pool cleaning.
Oxy Brite's active ingredient is a chemical provided by DuPont under the trade name
Oxone®. The chemical is known formally as pentapotassium bis(peroxymonosulphate)
bis(sulphate) , and more simply as potassium monopersulfate.
This chemical has a number of different uses, including odour control and specialized
treatment at wastewater treatment plant's (WWTP). It is promoted as an oxidizing agent in laundry detergents where chlorine is not desired. It has a high oxidizing potential of
1.85 eV , so it can oxidize a wide range of chemicals including odour causing compounds.
For comparison, chlorine has an oxidation potential of 1.4 eV, and hydrogen peroxide 1.8 eV. The oxidation by-product of Oxone® is sulphate sludge which is claimed to be
environmentally safe.
According to DuPont's chemists, Oxone® is not a significant source of DO and they suggest
using hydrogen peroxide which has a much greater DO potential and significantly lower
price per kg of active oxygen. Oxone® might lower chemical oxygen demand (COD) via
direct oxidation, which could indirectly reduce BOD. Rivas et. al. (2005) and Sun et. al.
(2009) compared Oxone® and hydrogen peroxide oxidation processes in high COD content

Predesign Report Short Term Wastewater Management Strategy
landfill leachate. The results showed that a greater reduction in COD occurred when using
Oxone® as an ox idizing agent. Concentrated Oxone® comes in a solid form reducing its
appeal.
2.2.6 Hydrogen Peroxide (H20 2)
Hydrogen peroxide (H20 2} has been used to reduce BOD, COD, and offensive odour in
domestic wastewater for many years (Ksibi M., 2006). The use of hydrogen peroxide is
recommended because it supplies supplemental DO when biological treatment systems
experience temporary overloads. Many biological treatment facilities dose H20 2 into
aeration basins or lagoons when they have poor BOD removal rates.
Hydrogen perox ide can detoxify a broad range of organic and inorganic wastes, including
sulfites, cyanides, aldehydes, and organic loading. Sufficient amounts of hydrogen
peroxide can oxidize many organic wastes down to carbon dioxide (C02). Usually that is
not necessary because a relatively small amount of hydrogen peroxide can cleave organic
molecules, reducing toxicity to acceptable levels, or making the molecules more easily
managed by a biological treatment system.
Hydrogen peroxide addresses the organic loading problem by providing supplemental DO
to the wastewater system which aerobic microorganisms use to increase the rate of
degradation of the organic loading. The oxidation potential of hydrogen peroxide is 1.8 eV.
This is comparable to the oxidation potential of Oxone®, which is 1.85 eV. Hydrogen
peroxide comes in a liquid form which is more convenient from a dosing point of view. The
dosing process requires only a small dosing pump and a barrel of hydrogen peroxide.
2.3 Selection of the Most Suitable Chemicals
Based on the evaluation of six chemicals hydrogen peroxide and Oxone® emerged as the best
choices. Hydrogen perox ide does not harm the environment. Also, it is less complex and less
costly to set up an automated dosing system which means that less labour is required. Hydrogen
peroxide addresses the organic loading problem by providing supplemental DO to the wastewater
system which aerobic microorganisms use to increase the rate of degradation of the organic
loading.
Table 2-1 shown below identifies the two most suitable chemicals and the cost per lot per year. On
this basis hydrogen peroxide is the recommended chemical. When compared with Oxone®,
hydrogen peroxide is a better ox idant of BOD, favours microorganism growth, has no harmful by
products and is one tenth of the cost. Costs shown below are set out on a cost per lot basis.
These costs do not include time and operating effort by the Town of Lumsden operating staff. Also
there is an administration effort required to order chemicals, work with developers to fund their
program and in general to ensure compliance with regulatory requirements.

Table 2-1 Cost of Providing Selected Chemicals per Lot for One Year
Chemical Cost per Lot per Year
Oxy Sparkle (Oxone~ $ 4,800
Hydrogen Peroxide $500
Table 2-2 shown below illustrates costs for hydrogen peroxide per year taking into account
increments of 10, 50 and 100 lots. The Town will need to approve the number of lots and therefore
the dosing requirements as land development proceeds.
Table 2-2 Cost of Hydrogen Peroxide for a Number of Lots per Year
Number of Lots Cost per Year
10 $5,000
50 $25,000
100 $50,000
The estimated cost of providing Oxone® for Lumsden is $4,800 per lot per year (Table 2-1 ). This is
significantly higher than the estimated cost of hydrogen peroxide which is $500 per lot per year. Also, from an operational point of view, dosing chemicals in a solid form is less favourable.
Concentrated Oxone ®comes in a solid form while hydrogen peroxide is in a liquid form.
2.4 Chemical Treatment Implementation
2.4.1 Dosing Location
Effective mixing of chemicals and wastewater is crucial to successfully treating BOD
loading using a chemical process. Effective mixing can be achieved in the pumping station by dosing hydrogen peroxide directly into the pipe downstream of the main pump. The
pumping station is heated in winter, is powered, and has ventilation fans, plus the Town's
foreman runs a daily inspection on the pumping station, providing the opportunity to
monitor and service the dosing system.
A shed adjacent to the pumping station would be needed to store chemicals. The number
of barrels to be stored in the shed for 30 days consumption in the first, second, third, and
5 P:\20114865100 _Lumsden_ Con_ Study\Engineering\03. 02_ Conceptuai_F easibility _Report\Final Report\rpl_ short_term_20120131 .doc
Predesign Report Short Term Wastewater Management Strategy
fourth years would be three, six, nine, and twelve barrels, respectively. Due to space
limitations at the pumping station, there would only be one barrel of hydrogen peroxide
allowed in the pumping station at any given time to feed the dosing pump. When all of the
hydrogen peroxide in the barrel is depleted, that barrel will be replaced with a full barrel of
hydrogen peroxide from the shed.
2.4.2 Dosing Options
2.4.2.1 Chemical Dosing Pump
Hydrogen peroxide can be dosed into the lagoon using a small chemical resistant
dosing pump described in Table 2-3. The pump would be connected to a hydrogen
peroxide barrel and the outflow would be pumped through a tee connection . The
tee connection would be tied into the air release valve which is located at the
downstream pipe of the main pump at the wastewater pumping station.

2.4.2.2 Full Package Hydrogen Peroxide Dosing System
An alternative full package option is available which would be implemented and
maintained by a commercial chemical provider called US Peroxide. US Peroxide
could lease both a dosing system and a storage tank. They supply hydrogen
peroxide (50% concentration) at the site plus they provide maintenance service as
shown in Appendix A.
2.4.3 Chemical Handling
Handling hydrogen peroxide requires consideration of a number of safety measures as
described in the hydrogen peroxide material safety data sheet (MSDS), which is included in
Appendix B. Hydrogen peroxide is considered to be non-combustible. However, on
decomposition, it releases oxygen which may intensify fire. Inhalation of hydrogen
peroxide mist or vapours may severely irritate the nose, throat, and lungs. It would be
6 P:\20114865100 _Lumsden_ Con_ Study\Engineering\03.02 _ Conoeptuai_F easibili ty _Report\Final Reportlrpt_ short_ term_20120131.doc
.l
Predesign Report Short Term Wastewater Management Strategy
necessary to implement a mechanical ventilation system and to provide a sufficient supply
of replacement air to make up for air removed by the exhaust system. Proper equipment for lifting and transporting containers would also be necessary. The
barrels would need to be stored in a cool, dry, well-ventilated location. Containers should
be tightly closed and out of direct sunlight. The barrels should not be stored on wooden
pallets; plastic pallets should be used instead. It is necessary to have a containment
system under the barrels.
Appropriate protective equipment for handling hydrogen peroxide would include chemical
goggles, a full-face shield , impervious gloves of a chemically resistant material, body suits
and/or coveralls of a chemically resistant material, and impervious boots of a chemically
resistant material. Emergency shower and eyewash stations should be in close proximity.
3 Physical Treatment
3.1 Blower Aeration System
This type of mechanical aeration system includes a blower, a header, connection pipes, and
diffusers. The system uses a grid of lateral piping equipped with diffusers to inject fine or medium
sized bubbles into the wastewater. The diffusers could be suspended slightly above the lagoon
floor, or they could rest on the bottom. Flexible airlines or a weighted air hose would be used to supply air to the diffuser unit. See Appendix C for a more detailed description.
3.2 Surface Aerators
A 2.2 kW (3 hp) surface aerator as described in Appendix D could be implemented. In a surface
aeration system, the aerator serves two functions: it transfers the air required by the
chemical/biological oxidation reactions into the lagoon, and it undertakes the mixing required to
disperse the oxygen into the wastewater. The surface aerators are rated to transfer 0. 7 to 1.5 kg 0 2/kWh under typical field conditions.
Low temperatures in winter can adversely affect the performance of surface aerators. In the
Lumsden project the amount of BOD loading from 50 lots is not enough to require the aerator to run
all the time. When the aerator stops, the water starts to freeze, wh ich may damage or otherwise
impede the aerator the next time it begins operating. However, there are anti-freezing kits and
attachments that could be used to prevent such potential issues.
3.2.1 Surface Aeration Design
BOD loading could be addressed by using surface aerators at the Town's existing lagoons.
A 2.2 kW (3 hp) or 3.7 kW (5 hp) surface aerator unit would be able to transfer enough
oxygen to the wastewater for aerobic biological organisms to oxidize organic compounds in the wastewater and address the BOD loading.
7 P:\20114865100 _Lumsden_ Con_ Study\Engineering\03.02_ Conceptuai_F easibility _ Report\Final Reportlrpt_ short_lerm_20 120131.doc
Predesign Report I Short Term Wastewater Management Strategy
A high-speed 2.2 kW (3h p) or 3.7 kW (5 hp) surface aerator as described in Appendix D
could be implemented. In a surface aeration system, the aerator serves two functions: it
transfers the air required by the chemical/biological oxidation reactions into the lagoon, and
it undertakes the mixing required to disperse the oxygen into the wastewater. The surface
aerator described in Appendix D is rated to transfer 0. 7 to 1. 5 kg 0 2/kWh under typical field
conditions.
Low temperatures in winter can adversely affect oxygen transfer into the lagoons. Using
the oxygen transfer equation from Section 5-12 of 'Wastewater Engineering Treatment and
Reuse, Fourth Edition' (Metcalf and Eddy, 2003), it is determined that an oxygen transfer
rate of 0.44 kg 0 2/kWh is applicable for winter time in Lumsden.
The Ministry of Environment's 'Guidelines for Sewage Works Design' (EPB 203) states that
a typical five-day biochemical oxygen demand (BOD5) for raw sewage from domestic
sources of 77 grams/capita-day (0.17 lbs/capita-day) may be considered for design of
wastewater works in Saskatchewan.
According to Community Profiles from the 2006 Census by Statistics Canada, the average
household size in Lumsden is 2.6 people. Table 3-1 shows the number of lots which could
be addressed by a 2.2 kW (3 hp) or 3.7 kW (5 hp) surface aerator. Note that the surface
aerator needs to operate 24 hours a day, 7 day a week.
Table 3-1 Estimated Number of Lots which could be Addressed by Using a Surface Aerator
Surface Aerator Number of Lots
2.2 kW (3 hp) 117
3.7 kW (5 hp) 196
When a surface aerator stops in subzero temperatures, the water around it starts to freeze,
which may damage or otherwise impede the aerator the next time it begins operating.
However, there are anti-freezing kits and attachments that could be used to prevent such
issues.
When using a surface aerator, it should be recognized that there are risks associating with
servicing such a unit in winter. The aerator maybe surrounded by thin layer of ice making it
essential to take precautions when approaching it. The Town has previous experiences
with surface aerators and it is understood that they are aware of these risks. However,
necessary safety measures should be taken when servicing the unit.

Cost Analysis
4.1 Comparison of Chemical and Physical Treatment Costs
Table 4-1 presents a comparison of the conceptual capital costs, engineering fees, annual operating costs, and four-year lifecycle costs for four treatment options. The conceptual cost estimates in Table 4-1 are meant to provide a basis for differentiating between options and should
not be taken as budgeting costs .

Blower Aeration System Package $51,100 $ 10,000 $18,000 $120,000
From Table 4-1, a surface aerator system is the most cost effective option .
4.2 Refinement of Surface Aeration Costs
From Section 4.1, a surface aerator system is the most cost effective option. The surface aerator
cost estimate is further refined in Table 4-2. Table 4-2 presents the estimated capital costs, annual operating costs, and four-year lifecycle costs for two surface aerators. Engineering fees are included in the capital cost and includes contacting suppliers, evaluating their proposals, submitting the required technical documents to the Ministry of Environment, and resident engineering during installation. The Town suggested that they have the resources to install the surface aerator .

From Table 4-2, a3.7 kW surface aerator provides the lowest cost per lot for reducing organic
loading at the wastewater treatment lagoons.
5 Conclusions and Recommendations
Based on the evaluation of chemical and physical treatment processes, a surface aeration system
is the most cost effective method of reducing organic loading on the Lumsden wastewater
treatment lagoons. Further analysis of surface aerators indicates that a 3.7 kW (5 hp) surface
aeration system is the most cost effective option.
Associated Engineering recommends that:
• The Town proceed with the detailed design and installation of a surface aeration system
including a 3.7 kW (5 hp) surface aerator at the existing wastewater treatment lagoons.
• AEon behalf of the Town apply for a Permit to Construct, Extend or Alter Existing works for
the installation of the surface aeration system.

NELSON ENVIRONMENTAL INC.
Proposal for:
Design, Equipment Supply and Installation for:
Lumsdon, SK OPTAER Wastewater Treatment System
July 27, 2011
Project Reference: cd356.03
1.0 Project Overview
An upgrade using Nelson Environmental Inc.'s OPTAER™ lagoon based wastewater treatment system is proposed for the town of Lumsdon, SK. A floating lateral with six (6) fine bubble diffusers will be installed. The proposed upgrade will increase the treatment capacity of the existing aerated treatment cell.
The following technologies will be constructed and/or implemented:
• Implement OPTAER™ fine bubble aeration with a floating lateral in cell1. • Install a blower with insulated shelter and control panel to supply air to the diffusers.
2.0 System Design Parameters
The OPTAER system is sized to contribute adequate oxygen to treat the following:

3.0 OPT AER Treatment Process
The primary purpose of the aerated ponds is to provide oxygen, residence and contact time to natural bacteria, which ultimately convert the wastewater contaminants (BODs, ammonia, and TSS) to carbon dioxide, water, and inert ash and nitrates. Aerated ponds effectively control odours and provide internal sludge digestion.
I. Partial Mix (PM) Cell/ Settling Cell
With aerated partial mix cells , the diffuser density is based upon oxygen demand. The OPTAER rM system does not rely on algae or natural surface aeration to provide oxygen to the wastewater.
The diffusers are suspended near the bottom of the cells. Through the rise of the bubbles and subsequent mixing, convection cells are created between the diffusers. Not only does the water rise with the bubbles, the solids settle out through the downward motion of the water between the diffusers where the circulation loop is completed. This combined with the slow rate of bubble rise contributes to the overall efficiency of the system.
When the solids reach the bottom of the lagoon, additional oxygen for biodegradation is provided through the diffusers near the cell bottom. This process results in minimal organic bottom sludge accumulation. Aerobic digestion takes place within the aerated cells at the sludge water interface. Because of low sludge production in the system, retention time is retained for long term BODs removal.
4.0 Aeration Processes
I. HA-16 Fine Bubble Membrane Diffusers (Partial Mix Cells)
HA-16 fine bubble membrane diffusers are used to provide oxygen to the wastewater. The diffusers are constructed with a HOPE air distribution body with individual tubular micro-porous membrane fingers extending outwards in a horizontal plane. This unique design prevents bubbles from coalescing, and results in an exceptional oxygen transfer rate with minimal head loss.
The diffusers are suspended with a marine grade rope directly under the lateral, at a uniform depth. The rope is attached to the floating header for ease of diffuser retrieval. Each diffuser is attached to a small concrete weight, encased in HOPE pipe. Diffuser assemblies can be retrieved from a boat with no special equipment.
11. OPTAERTM Header System (Aerated Cells)
Galvanized metal manifold/discharge piping is used to dissipate the heat produced by the blowers. The metal piping is connected to the HOPE floating lateral. With floating laterals, there are no concrete weights required to be in contact with the bottom of the lagoon. Laterals are secured against wind action with a stainless steel cable system. The cables are fastened to anchors in the lagoon berm using a self-adjusting lateral tensioning assembly. All header and lateral piping, joints, and fittings are thermally fused HOPE.
Page 3 of 4
With floating laterals the cells do not have to be dewatered or taken out of service for system installation or maintenance. All maintenance can be performed from a boat with a 2-person crew.
I. Positive Displacement Blowers
Air supply for the OPTAER™ Lagoon aeration system will be provided by one (1) 5 hp positive displacement blowers capable of providing 60 SCFM at a discharge pressure of 6.0 psi. The blower would operate at 3.4 bhp. The blower is equipped with an outdoor sound attenuating enclosure.
