What does the Trump presidency mean for the environment and for Canada?


ike it or not, Canadians have to accept it that Donald J. Trump is now the 45th President of the United States. So many long-standing political issues are now in flux, including infrastructure, water, climate change, etc. With control of the Presidency, Congress and likely the Supreme Court, President Trump and the Republican Party will have the opportunity to make sweeping changes in the next four years. Based on his proficient use of Twitter, countless speeches and his campaign website, it’s fairly clear where the new president stands on key environmental issues. As far back as 2012, Trump tweeted that “the concept of global warming was created by and for the Chinese in order to make US manufacturing non-competitive.” Since then, he has tweeted dozens of times about how he does not accept that climate change is real. (@realDonaldTrump) He has stated he wants to dismantle the Paris Agreement that some 200 countries agreed to last year. Its goals are to reverse the worst effects of global warming. Trump has been quoted as saying that the United States shouldn’t waste “financial resources” on climate change and should instead use them to ensure the world has clean water, eliminate diseases like malaria, increase food production, or develop alternative energy sources. The President has said that clean water may be the “most important issue we face as a nation for the next generation. We must make the investment in our fresh water infrastructure to ensure access to affordable fresh water solutions for everyone.” He said on ScienceDebate: “We must explore all options to include making desalinization more affordable and working to build the distribution infrastructure to bring this scarce resource to where it is needed for our citizens and those who produce the food of the world.” (www.sciencedebate.org) Trump has said he wants to keep public lands in the control of the federal government. “In a Trump administration, there will be shared governance of our public lands and we will empower state and local governments to protect our wildlife and fisheries,” he also said on ScienceDebate. “Laws that tilt the scales toward special interests must be modified to balance the needs of society with the preservation of our valuable living resources.” During the first few days of his term, President Trump issued an Presidential Memorandum to restart the Obama-blocked Keystone XL pipeline from Hardisty, Alberta, to Steel City, Nebraska, as part of his plan to expand the oil industry. However, he wants financial compensation from TransCanada Corp. to the US Treasury in exchange for approval. Also, he wants the pipes to be manufactured in the United States. Canada’s Natural Resources Minister Jim Carr believes that, despite President Trump’s protectionist stance, TransCanada can work out a deal that allows much of the work, such as assembling the pipe, to be done in Canada. Prime Minister Justin Trudeau welcomed the President’s move to revive Keystone, saying: “I’ve been on the record for many years supporting it because it leads to economic growth and good jobs for Albertans”. It should be noted that under President Obama’s “Buy-American” policy of 2009, Canadian companies also faced challenges when dealing with the US. Free and fair trade between our two countries, as well as other mutual concerns like water supplies, cross border air quality, environmental protection, etc., have always been up for debate and negotiation. Canadians can only hope that our leaders feel as passionate about our interests, as US leaders do about theirs. Steve Davey is editor and publisher of ES&E Magazine. Email: steve@esemag.com

A new report released by the Forum for Leadership on Water (FLOW) urges the federal government to make innovative and sustainable urban water infrastructure a top priority for its 10-year, $180 billion infrastructure plan. “Smart, Strategic Investments for Urban Water Sustainability: Seizing Canada’s Infrastructure Moment” cites findings of the 2016 Canadian Municipal Infrastructure Report Card, which found that 35% of Canada’s wastewater infrastructure and 29% of drinking water infrastructure is in ‘fair to very poor condition’. The report’s recommendations include: • Prioritizing climate readiness and solutions that get the most out of existing infrastructure – Project proposals should be screened to ensure that planned infrastructure can withstand extreme weather conditions such as the heavy rain events as a result of climate change, and

WE PROVIDE: New AUMA Intelligent Actuators

to prioritize solutions that maximize the capacity of existing water and wastewater treatment facilities before investing in new, large-scale expansion. • Dedicating funding for sustainable solutions – Specific funding streams should be created to support sustainable solutions, including water conservation and efficiency programs, optimization of wastewater facilities, living green infrastructure such as urban stream restoration and retention ponds, and technologies that generate energy and recover valuable resources such as nutrients from wastewater. • Updating regulations – Existing federal wastewater regulations should be updated to strengthen environmental performance, address new contaminants, including pharmaceuticals and micro-plastics, and promote uptake of innovative Canadian technologies and practices. www.flowcanada.org


The Town of Windsor, Nova Scotia has completed its new wastewater treatment facility. According to Infrastructure Canada, the new plant incorporates the latest technologies to meet the standards of the federal Wastewater Systems Effluent Regulations and improve reliability. It will greatly reduce the amount of effluent released into the St. Croix River and eliminate combined sewage overflows. The new facility has more capacity, servicing approximately 780 additional households and allowing for future growth. Funding came from the Government of Canada ($2.9 million), the Town of Windsor ($169,510 from federal Gas Tax funds) and the Government of Nova Scotia ($3.8 million).

Work at the three plants involved expanding and renovating buildings to accommodate new and upgraded equipment designed to improve filtration, decantation and disinfection efficiency. The pumping and automation systems were also upgraded to ensure greater control over water treatment processes. Upon completion, the governments of Canada and Quebec will have each contributed $46,820,000, for a total of $93,640,000. The City of Laval will have contributed $100 million to complete this project. The City of Regina, Saskatchewan, recently announced that upgrades to its wastewater treatment plant are substantially complete and all new process systems are in service. The upgrade project increases the plant’s capacity from 70 ML/D to 92 ML/D and converts the treatment process to a biological nutrient removal process, according to engineering consulting firm Stantec. The project was completed by EPCOR

These programs involve SaskPower, the Water Security Agency and multiple watershed groups across the province. In total, 70 water bodies were included in the sampling and monitoring program. In addition to the monitoring and educational programming, provincial regulations allow conservation officers to inspect, quarantine and decontaminate watercraft, known or suspected to contain aquatic invasive species.

New study examines the effectiveness of different ozone dissolution methods


zone systems commonly use either fine bubble diffusion (FBD) or sidestream injection (SSI) for gas-liquid mass transfer of ozone into water. In the early 2000s, SSI emerged as an alternative to FBD, due to easier access to process components, lack of diffuser maintenance, improved transfer efficiency, and reduced capital costs associated with deep ozone contactors. However, SSI has some limitations, including the operating cost of pumping and the potential for water condensation and nitric acid formation in sidestream components. Most newly constructed ozone systems are now using SSI, and some existing FBD systems have been retrofitted with SSI. In manuals related to the Surface Water Treatment Rule (SWTR) and Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR), the US Environmental Protection Agency (EPA) has provided guidance for calculating disinfection credits for viruses, Giardia, and Cryptosporidium. The typical contactor configuration in these guidance manuals involves gas-liquid mass transfer in the first dissolution chamber (FBD), followed by ozone exposure (CT) determination in subsequent chambers (disinfection zone). Under this scenario, there is no disinfection credit received for ozone exposure in the bubble column (referred to in this study as Dissolution CT). The significance of Dissolution CT in full-scale treatment has not been extensively studied. Similar guidance can be used for SSI systems with degas, where disinfection CT credit can be calculated, beginning at the point of blending the sidestream flow with the full water flow. Differences between these methods of ozone dissolution (FBD or SSI) were found to have a significant effect on ozone disinfection credit and bromate formation at the Regional Municipality of Halton in Ontario. During an investigation of three full-scale treatment facilities operated by 18 | February 2017

Ozone (O3 ) is one of the strongest disinfectants and oxidants available in drinking water treatment and has been used continuously for over 100 years.

Halton, the SSI facility provided greater CT and less bromate compared to the two FBD facilities when operated under similar ozone dose conditions. Full-scale observations at Halton prompted more questions regarding the design and operation of both FBD and SSI systems. Ozone industry experts determined that further investigation of several design and operation issues at pilot scale was warranted. This resulted in a study initiated by the Water Research Foundation. Pilot-scale testing of FBD was recommended to further investigate the significance of Dissolution CT and corresponding bromate formation under counter-current and co-current flow conditions. Pilot-scale testing of SSI systems was recommended to further investigate the effect of design (e.g., gas to liquid ratio, pressure, contact time, ozone concentration) and water quality (i.e., bromide) parameters on mass transfer efficiency and bromate formation in the sidestream and blended flow. The results are intended to further the understanding of design and operation of the systems by design engineers and utilities.

FINE BUBBLE DIFFUSION SYSTEMS At design flow, FBD systems are typically designed so the first contactor chamber has 1-3 minutes of contact time and a diffuser depth of around 18-22 ft, resulting in a hydrostatic pressure of around 10 psi. However, full-scale plants are rarely operated at design flow. If parallel contactors are not taken out of service, the contact time increases in the dissolution chamber. This operating condition can result in higher detention time in the dissolution zone, resulting in significant ozone exposure and bromate formation that are not considered in the regulatory CT calculation for disinfection. Pilot-scale results showed that ozone exposure (0.31 mg-min/L) and bromate formation (0.8 μg/L) are minimized in the dissolution chamber when operating at design flow (25 gpm, t=2 min). When reducing the flow rate to 10 gpm and 6 gpm, contact time increased to 5 min and 8.5 min, respectively. The reduction in flow increased the Dissolution CT to 1.45 and 2.85 mg-min/L and bromate formation to 5.6 and 9.1 μg/L, respectively. Similar results were observed, whether continued overleaf...

the contactor was operated under counter-current or co-current flow conditions. Testing was also completed to investigate the effect of bubble size on ozone mass transfer. Results showed no significant differences between bubble diameters of 2 and 15 μm. Under the EPA guidelines for determining disinfection credit, CT in the dissolution chamber is not included in the CT value for compliance. For FBD systems it is recommended to operate the plant under conditions near design flow to minimize the contact time in the dissolution chamber. Also, operators should consider taking parallel contactors out of service in order to minimize contact time in the dissolution chamber.

SIDESTREAM INJECTION SYSTEMS Pilot-scale testing of SSI systems (with and without degas separation) was performed to investigate the effect of various design and water quality parameters on mass transfer efficiency and bromate formation. Increasing gas to liquid (G/L) ratio did not impact transfer efficiency for sidestream-without-degas (SSIwo-dg), likely due to mass transfer occurring at both the venturi and pipeline flash reactor (PFR). Dissolved ozone residuals increased after blending the sidestream with the full flow at greater G/L ratios, indicating that more transfer is taking place at the PFR. Increasing G/L reduced the transfer efficiency during sidestream-with-degas (SSIw-dg), likely due to mass transfer occurring only at the venturi. The dissolved oxygen (DO) concentration following SSIwo-dg (20 mg/L) was greater than SSIw-dg (14-17 mg/L). Bromate formation remained below 10 μg/L in the sidestream when operating with either SSIwo-dg (sidestream ozone dosages up to 10 mg/L) or SSIw-dg (sidestream ozone dosages up to 18 mg/L). After blending with the full-flow, the contribution of bromate was <2 μg/L under the conditions tested. Water pressure downstream of the injector did not appear to impact transfer efficiency (TE) under the conditions in this study. However, water pressure upstream of the injector did appear to impact transfer efficiency during both 20 | February 2017

During an investigation of three full-scale treatment facilities operated by Halton, the SSI facility provided greater CT and less bromate compared to the two FBD facilities when operated under similar ozone dose conditions. SSIw-dg and SSIwo-dg. The decrease in TE with reduced injector upstream pressure was more apparent in SSIw-dg. Upstream pressure was reduced from 60 psi to 35 psi. Increasing water pressure from 1 to 12 psi at the point of blending (i.e., PFR) increased the dissolved ozone residual up to 0.70 mg/L. Increasing the ozone feed gas concentration (6%-13%) did not appear to impact the transfer efficiency in either SSIwo-dg or SSIw-dg. However, all other operating parameters were kept constant during pilot testing (e.g., G/L ratio), which is likely not the case in full-scale installations. In full-scale systems, increasing ozone concentration will reduce G/L ratio, and reduction in G/L ratio did result in an improvement in TE. Increasing the raw water bromide concentration from 70 to 170 μg/L resulted in nearly double the amount of bromate formation in both the sidestream flow and blended flow. A contact time of up to 10 minutes was simulated in the sidestream flow, using a batch reactor. Results showed that bromate formation can be significant if exceeding the design recommendation of <5 seconds in the sidestream flow. When operating SSIwo-dg at lower G/L ratios (<0.10), the majority of mass transfer occurs at the injector and less mass transfer is required at the flash reactor. When operating SSIwo-dg at higher G/L ratios (>0.10), mass transfer occurs at the injector; however, additional mass transfer is required when combining the sidestream with full water flow (e.g., pipeline flash reactor) to achieve high transfer efficiency. When high mass transfer is achieved in SSIwo-dg at higher G/L ratios (>0.10), then greater initial residuals may exist, entering the disinfection zone for potentially greater “Compliance CT.” Increasing the water pressure upstream of the venturi may improve ozone mass

transfer efficiency. Increasing the water pressure at the point of blending (i.e., PFR) may improve mass transfer efficiency when operating with SSIwo-dg. Equally, or probably more, important is the need for good mixing in the full-flow in order to develop small bubbles that are necessary for ozone transfer at that location. Finally operators should minimize the exposure time in the sidestream flow as much as possible to minimize the ozone exposure and corresponding bromate formation. Typical design of sidestream flows is less than 5-6 seconds. www.waterrf.org

For it to operate, there must be solid particles or air bubbles in the stream to reflect the ultrasonic beam. The motion of particles shifts the frequency of the beam, which is received by a second transducer. The flow meter measures the frequency shift, which is linearly proportional to the flow rate. This value is multiplied by the internal diameter of the pipe to derive volumetric flow. As the Doppler ultrasonic flow meter relies on particles flowing in the liquid to operate, consideration must be given to the lower limits for concentrations and sizes of solids or bubbles. In addition, the liquid must flow at a rate high enough to keep the solids suspended.

A portable Doppler ultrasonic flow meter.

Understanding the differences between Doppler and transit time ultrasonic flow meters


ltrasonic flow meters are non-intrusive devices that use acoustic vibrations to measure the flow rate of liquid. There are two types: Doppler and transit time. Both are designed to clamp onto the outside of the pipe without breaking the line or interrupting flow. This also eliminates pressure losses and prevents leaking. In addition, the flow meter does not come in contact with the liquid, thereby preventing corrosion or deterioration of the sensors. Although Doppler and transit time flow meters operate on a similar principle, the technology varies significantly. To obtain accurate measurements, it is 22 | February 2017

important to know which flow meter to use for your application.

DOPPLER ULTRASONIC FLOW METERS Doppler ultrasonic flow meters operate on the principle of the Doppler Effect, which was documented by Austrian physicist and mathematician Christian Johann Doppler in 1842. He stated that the frequencies of the sound waves received by an observer are dependent upon the motion of the source or observer in relation to the source of the sound. A Doppler ultrasonic flow meter uses a transducer to emit an ultrasonic beam into the stream flowing through the pipe.

TRANSIT TIME ULTRASONIC FLOW METERS Transit time ultrasonic flow meters measure the difference in time from when an ultrasonic signal is transmitted from the first transducer until it crosses the pipe and is received by the second transducer. A comparison is made of upstream and downstream measurements. If there is no flow, the travel time will be the same in both directions. When flow is present, sound moves faster if traveling in the same direction and slower if moving against it. Since the ultrasonic signal must traverse the pipe to be received by the sensor, the liquid cannot be comprised of a significant amount of solids or bubbles. This is because the high frequency sound will be abated and too weak to travel across the pipe. The difference in the upstream and downstream measurements taken over the same path is used to calculate the flow through the pipe. The transit time ultrasonic flow meter has three possible transducer configurations: Z, V and W. All are recognized as a single measuring path, whereas the ultrasonic beam follows a single path. In all three configurations, the output produced by the transducers is converted to a current, frequency or voltage signal. The preferred configuration is determined by factors such as: pipe size; space available for mounting the transducers; condition of the intercontinued overleaf...

buildup of scale on the interior walls of the pipe. It should be avoided for installations on small pipes, where the accuracy of its measurements tends to degrade. The “V” configuration is recommended for most installations. This arrangement places the two transducers on the same side of the pipe within approximately a diameter of the pipe from each other. A rail attachment clamps on the pipe and allows the transducers to be moved horizontally to position them the calculated distance apart. A “W” configuration is most often used for installations on pipes with dia​meters of 12 mm – 40 mm. In this arrangement, the ultrasonic signal rebounds from the wall three times; therefore, it must travel a greater distance. High turbidity liquids and built-up scale or deposits on the interior of the pipe wall can diminish accuracy.

FACTORS INFLUENCING ACCURACY The accuracy of ultrasonic flow meter measurements relies on proper mounting. Large temperature changes in the pipe or a significant amount of vibration may affect the alignment of the transducers and acoustic coupling to the pipe. These factors must be accounted for during installation. In addition, to provide an accurate volumetric flow rate, all ultrasonic flow meters require that the pipe be full. A Doppler ultrasonic flow meter on a partially filled pipe will continue to generate flow velocity measurements if both transducers are mounted below the fluid level in the pipe. The two types of ultrasonic flow meters, Doppler and transit time, each function by way of two different technologies. An understanding of how each operates enables the selection of the appropriate flow meter. For more information, email Kathleen Kwiatkowski,Omega Engineering, Inc., kkwiat@omega.com

Using anaerobic moving bed biofilm reactors for brewery wastewaters By Alessandro di Biase, Tanner R. Devlin, Maciej Kowalski and Jan A. Oleszkiewicz


he market is hot for a cold one and the brewing industry is experiencing unprecedented growth. The number of licensed breweries in Canada has more than doubled to some 640 in the last five years. In spite of 70% of the market by produced volume allocated to macro-breweries such as Anheuser​ -Busch and Molson Coors, craft breweries are flooding the national market. Most breweries that have emerged since 2010 would be considered small, with 200 m3 – 500 m3 of annual beer production. With production increasingly spread across small-scale breweries, there is a challenge to efficiently and cost-effectively address wastewater treatment. Craft brewing involves several unit processes, with some generating unique waste streams. For instance, “whirlpooling” is a solids separation process usually performed in the brew kettle. It removes undesirable components such as hops and coagulated proteins from sugar-rich wort that will be converted to beer during fermentation. The waste from whirlpooling is collectively known as trub and contributes significantly to oxygen demand and suspended solids in brewery wastewater. Other sources of waste include spent grains from lautering, another form of trub from fermentation (heavy fats, proteins, and inactive yeast), as well as acidic and caustic cleaning agents. The amount of potable water required to generate one litre of beer ranges from 4 – 10 litres as noted in the 2011 Brewers Association’s report on water and wastewater. Subtracting one litre for the beer produced and considering a 10% reduction for evaporation and minor losses, the estimated range of wastewater production would be 2.6 – 8 litres per one litre of beer produced. The actual quantity of water consumed by individual breweries will depend on the type of brewing process used, size 26 | February 2017

of the brewery, packaging system, and water conservation measures. Packaging generates the largest volume of wastewater, depending on the type of packaging and technology employed. Between breweries, the characteristics of combined, “end-of-pipe” wastewater vary widely. The Brewers Association provides typical ranges for total chemical oxygen demand (COD) at 1,800 mg/L – 5,500 mg/L, biochemical oxygen demand (BOD) at 600 mg/L – 5,000 mg/L, total suspended solids (TSS) at 200 mg/L –

1,500 mg/L, and pH at 3 – 12. The latter is dependent on chemicals used for cleaning and washing operations, including packaging. Concentrations exceed these ranges for breweries with low water consumption. This was observed at a local Manitoba brewery with average BOD of 5,400 mg/L, as well as by ECONSE in Toronto, who treated an average BOD of 6,900 mg/L craft brewery wastewater. These concentrations elicit methods continued overleaf...

to meet sewer by-laws before discharge. For small craft breweries, addressing the sewer by-laws can be as simple as pH adjustment and payment of municipal fees per kg of discharged pollutant (COD, nitrogen, phosphorus, etc.). For larger breweries, full biological pretreat-

ment may be implemented to avoid fees altogether. The decision as to the extent of pretreatment depends on the size of the brewery and the magnitude of discharge fees. In Winnipeg, for example, these are $910/t TSS above the concentration

limit, $1,120/t BOD over the limit, and $5,000/t phosphorus discharged over the limit of 10 mg/L. Among the pretreatment options for brewery wastewater, anaerobic processes have been prominent for larger breweries. In the case of discharge to a natural receiver, they would be followed by an aerobic process. A relatively new option for pretreatment is offered by an anaerobic moving bed biofilm reactor (AMBBR).

ANAEROBIC MOVING BED BIOFILM REACTOR Moving bed biofilm reactors rely on synthetic carrier material, such as thin polyethylene matrices, to support biofilm growth. Biofilm carriers are retained in continuously mixed basins by effluent retention screens. This decouples solids retention time of the biofilm from the hydraulic retention time of wastewater flowing through. This makes the moving bed biofilm reactor ideal for intensifying biological processes, dependent on slow growing microorganisms such as the methanogens utilized under anaerobic conditions. There is no need for biomass recycle, or sludge age monitoring/control, since the biomass grows on carrier material that is physically retained in the reactor. The AMBBR is an energy efficient, high-throughput, low maintenance on-site brewery wastewater treatment option. An AMBBR can also facilitate biogas recovery for larger installations.

IMPLICATIONS FOR DESIGN More than two years of extensive research has been carried out at the University of Manitoba’s Environmental Engineering Group to develop unit design parameters. Wastewater from a Manitoba brewing company producing 50 m3/d beer and 150 m3/d wastewater was used. Cubical AC920 biofilm carriers (Headworks BIO, CA) were used with total and protected surface areas of 920 m2/m3 and 680 m2/m3 respectively. Protected surface area refers to the area available for biofilm formation, while total surface area includes the outer surface that is subjected to abrasion from mixing and contact with other biofilm carriers. It was initially demonstrated that the process was capable of handling volumetric loadings up to 20 kg sCOD/(m3/d) at 35°C when a continuously stirred-tank reactor was filled with 25% AC920 media by volume. A relationship between surface area loading rate (SALR) and corresponding percent soluble sCOD was developed. When investigating percent removal as a function of increased organic loading rate (by decreasing hydraulic retention time) a “tipping point” in performance was observed. The transition from good to poor performance corresponded to biofilm outgrowing the protected surface area and causing diffusion limitation. The biofilm had essentially clogged the media’s interior channels, resulting in an active surface area more or less equivalent to the outer surface areas of the channels, instead of the protected surface area. Although the media contained a significant amount of biomass, only a portion of it was available for treatment. Thus, it was concluded that SALR should not exceed 50 g sCOD/(m2/d) at 35°C in order to avoid mass transfer limitations on the AC920 media. The AMBBR had also proven to be flexible at different continued overleaf...

operating temperatures. Biofilm initially developed in 35°C was then acclimated to 25°C and 15°C in two parallel continuously stirred units. A control reactor was also operated in parallel at 35°C, to monitor the impact of external changes apart from temperature. Surface area loading rates varied from 10 g – 20 g sCOD/(m2/d) as a result of fluctuating characteristics in the brewery wastewater. Once the biofilm had acclimated to the new temperature and quasisteady state was achieved, average sCOD removal was 89%, 75%, and 65% at 35°C, 25°C, and 15°C respectively. It was also observed that changes in SALR at lower temperatures had a more significant impact on percent sCOD removal than at higher temperatures. Overall, these results indicate that the AMBBR is a robust technology capable of meeting the needs of small breweries to provide effective treatment within reduced footprints, with potential for biogas recovery.

THE CHASER As the industry continues to expand with proliferation of small to medium sized craft breweries, there will be a need to address its impact on sewerage systems and the cost of pretreatment versus payment of sewer discharge fees. Next generation wastewater treatment technologies should provide reliable on-site pretreatment within smaller footprints. Ease of operation and high throughput, along with the potential for biogas recov-

ery, place the AMBBR as a competitive option for treating high organic strength wastewater typical of breweries across Canada. Alessandro di Biase, Tanner R. Devlin, Maciej Kowalski and Jan A.

Customizing water efficiency solutions for industrial manufacturers By Alyssa Cerbu and Eric Meliton


he manufacturing sector in Canada faces many challenges related to international competition. To remain competitive, companies must seek viable solutions while still complying with industry standards, such as Good Manufacturing Practices for food and beverage and pharmaceutical manufacturers. One such challenge is the rising costs of production due in large part to the costs of inputs, such as energy and water. For a small to medium sized business especially, these strains can hurt profit and overall security. Therefore, it becomes more important to try to minimize costs and maximize resource productivity in a way that is feasible for the business, remains in line with their existing operations and ensures compliance with their industry’s regulations. Partners in Project Green, a group within the Toronto and Region Conservation Authority, works with businesses in the Greater Toronto Area to help customize solutions for their various environmental challenges. It has been developing a series of capital projects to showcase best practices in water stewardship and what is feasible for any set of operations.

PARTNERS IN SUSTAINABILITY PROGRAMMING Partners in Project Green works with the Region of Peel, York Region and City of Toronto to increase the effectiveness of existing municipal water efficiency programs. Through enrollment in these municipal programs, commercial and industrial manufacturers can obtain capital efficiency recommendations they can implement to realize savings on their utility bills. Frequently, however, businesses do not know where to start and find that water efficiency is not a concern for all internal stakeholders. Through the Innovative Water Technologies Program, member organizations can gain access to a network of experts www.esemag.com

WATER TREATMENT Table 1. System retrofits at Dextran Products Ltd.




Temperature regulating valve for vacuum pump: The process utilizes a sludge machine that filters out iron from wastewater utilizing a vacuum pump, which requires cooling water.

System did reuse some water, but a large volume of water going down the drain had additional cooling capacity.

A new temperature regulating valve allows the flow to be regulated to remove only the necessary amount of heat from the vacuum pump. Cooling water is now sent to a storage tank to be reused by the scrubbers, thereby halving the amount of water going down the drain.

Connecting reactors to cooling tower: The reactor vessels are where production takes place and require cycles of heating and cooling.

Municipal water went straight down the drain after cooling phase.

Through connecting three reactors to the cooling tower, they will be reducing water consumption associated with cooling tower.

Cooling tower sump: Water utilized for their cooling tower.

Cooling tower was using a large volume of make-up water and sump was constantly overflowing.

Working to increase blowdown setpoint to reduce the volume of make-up water used by their cooling tower. Float valve was fixed to stop overflow of the cooling tower sump.

Resin regeneration: A resin tank is used in a production step that utilizes water in various stages.

A lot of the water was unsuitable for reuse and sent down the drain due to its acidic or basic properties.

Through installing controls and piping, acceptable water will be sent to the scrubber water make-up tank for reuse.

Condensate recovery system: Reactor vessels in the process are heated with steam that is generated in a boil and, later, condenses.

Condensed water was sent to drain at each reactor.

The hot, condensed water is used to preheat the make-up water for the boilers thereby reducing energy and water consumption.

Reverse osmosis system: A significant step in production process is distillation.

Process water, a mixture of water and sugar, was sent to drain after distillation.

A reverse osmosis system filters the water and sugar so that water can be reused as scrubber make-up and the remaining, concentrated sugar can be potentially sold.

Pump cooling: A pump in the boiler room requires water for cooling and to maintain a seal.

Cooling water was going to the drain.

Cooling water will be sent to the scrubber water make-up tank for reuse.

applications include: adjuvants, emulsifiers, carriers and stabilizers in pharmaceutical and cosmetic preparations. The company was paying extremely high water bills, upwards of $230,000 on average per year. Although this excessive cost was a primary motive for their capital project installation, they also wanted to promote themselves as a greener, more ethically responsible company which complied with regulations and participated in programs with the City of

Toronto (i.e., Sewer Use By-Law, Industrial Water Rate and Sewer Surcharge Rebate). Through its retrofits, Dextran Products wanted to also capitalize on monetary incentives available from Partners in Project Green, as well as Enbridge, for reducing water and natural gas usage in their processes. Additionally, these efforts would ensure Dextran Products were compliant with water quality pharmacopeia standards for its products around the world, thereby

allowing them to ship globally.

HOW DEXTRAN’S SYSTEM WORKS According to different global pharmacopeia standards, Dextran Products, as a compliant pharmaceutical manufacturer, cannot reuse water in their product. By customizing their manufacturing process, however, they are able to reuse water in other processes within their operations (i.e., boilers, rinse systems and systems that do not require fresh-

water), without directly impacting the purity of the final products. They are, therefore, able to cut down on their resource use and save money while still maintaining and complying with industry and sector standards. A customized solution to process water and wastewater challenges can really work with an organization’s existing infrastructure needs, which, in this case, involved compliance with restrictive pharmaceutical manufacturing regulations. Their intricate system went through several design phases with Enviro-Stewards Inc. and is incredibly interconnected. It is a good example to showcase that several small changes in one’s manufacturing process can equate to large, overall water and energy cost savings. Details of their overall system retrofits are provided in Table 1. Overall, through closing these loops and adjusting their process, Dextran Products are able to save 45,450 m3 of water annually, which had an equivalent cost savings in 2016 of $109,760. They

also directly benefited from an additional $10,000 worth of natural gas saving and $600 in cooling tower treatment chemicals. Should they be able to filter some of the sugar from the water, they will be able to benefit from an approximate $8,800 from the sale of concentrated fructose.

Innovative Water Technologies project was facilitated through the support of the vendor network. The ultimate goal is to utilize Dextran Products’ success to showcase to other manufacturers in the Greater Toronto Area that it can be beneficial to enroll in municipal water efficiency programs. LESSONS LEARNED Also, this project can help encourage Through customizing their system, other businesses to explore water reuse Dextran Products were able to directly and energy efficiency improvements benefit from small process changes within their own facilities. that had low costs and risks associated Process water and wastewater effluent with implementation that added up to improvements in a facility do not have a larger water and energy cost savings to be complex and expensive to add impact.

Water Research Foundation project creates biofiltration knowledge base


iological filtration (biofiltration) is the operational practice of managing, maintaining, and promoting biological activity on granular media in a filter to enhance removal of organic and inorganic constituents before treated water is introduced into the distribution system. Biofiltration systems are widely operated throughout North America by surface water facilities that utilize bacteria to treat and enhance their finished water quality. Some utilities have varying levels of unintentional biofiltration occurring without the process being fully accepted (e.g., granular activated carbon filter caps). Together, these facilities have a number of different design configurations and treat a wide range of water qualities. To date, there has been no complete summary of the existing biofiltration facilities in North America and the context in which they operate. One of the major barriers to more widespread acceptance of biological filtration is the lack of recognized fullscale experience and accepted design and operating parameters. A recent Water Research Foundation project has created an interactive Knowledge Base tool to aid water utilities in the evaluation of biofiltration as a viable and proven approach for drinking water treatment. The tool was designed to provide facility design, operating details, and industry-wide experience of biofiltration systems so users can analyze the information presented and determine the best approach for implementing and operating biofiltration facilities. The Knowledge Base contains current industry terminology, a technical reference list, links to WRF-funded biofiltration research reports, full-scale case studies and frequently asked questions. It also contains a relational database containing planning, evaluation, design, and operating information from utilities across Canada and the US. This database provides downloading options, as well as a survey portal for uploading new information. The 34 | February 2017

basic design of the Knowledge Base is comprised of an input module (e.g., survey), a warehouse module (e.g., database) and an output module (e.g., reports). Through the survey, utilities can enter relevant data into the Knowledge Base and query stored information. The warehouse module houses biofiltration utility information, case studies, links to reports, frequently asked questions, and other downloadable resources. It also serves as the source for the reporting module, which generates downloadable utility information reports, based on reconfigured queries by geographic region, phase, or facility size. The reporting module also allows for comparison of the user’s data entries to the industry and a download of industry data to various software formats. To obtain information from participating utilities for the Knowledge Base, an initial survey structure was assembled, reviewed, and optimized to create a balanced questionnaire that addressed key factors for implementing biofiltration. To summarize the results of the Knowledge Base and participant surveys, a Current Practices Manual was assembled to create a resource that addresses design, operation, and monitoring of biofiltration systems.

PLANNING To identify motives for biofiltration implementation, key drivers for biofiltration at water utilities were evaluated for initial planning stages. Enhanced treatment performance and finished water stability were widely recognized as benefits of biofiltration. Other advantages, such as energy and chemical cost savings and process sustainability, were also reported. Regulatory support and public perception were also factors considered as limitations. Taste and odour concern was reported as the most common driver, followed by improving filter performance and total organic carbon removal. In addition, several facilities indicated that disinfection byproduct removal and water quality in the distribution system were strong drivers for implementing biofiltration. Conversely, consideration was also given to the negative impacts of investing in biofiltration systems, such as uncontrolled biological fouling and failure of associated biofiltration equipment.

Changing characteristics of wastewater means using different pumping options By Michael Blundell


re-moistened personal wipes and related fibre-based products, such as baby wipes, disposable diapers and hygiene products, have become very popular with consumers and an important growth area for manufacturers. Personal wipes alone are a $6-billion industry in North America. It is projected to grow by 6% annually for at least the next five years. However, for operators of municipal wastewater treatment systems, the accelerating use of these fibre products, which are often marketed as being “flushable”, is a growing problem. Unlike traditional toilet paper, which breaks down relatively quickly in the waste stream, the new products are tough and durable. They remain largely intact in the sewer system, where they can form large masses which can obstruct and clog pumps. The Municipal Enforcement Sewer Use Group (MESUG), made up of 25 Canadian communities, has estimated that efforts to deal with blockages from the new fibrous products are costing Canadian ratepayers at least $250-million a year.

Reduced water flow in sewer systems from conservation measures has compounded the problem of clogging prone materials by resulting in a "thicker" wastewater flow.

Anti-clogging impeller designs: These offer reduced sensitivity to clogging, thanks to specially contoured leading edges that are shaped to avoid catching fibrous material and the elimination of the troublesome gap between the impeller shroud and the volute casing. These impellers have generous clear passages and can pass reasonably large chunks of solid waste.

that has the best chance of dealing with these specific challenges. While appropriate impeller selection can drastically reduce the occurrence of clogs, it is still recommended to have a plan in place to address clogs when they do occur. One option is to run the motor backwards, reversing the flow and clearing the blockage. The “deragging feature” can be helpful in the short term, but, of course, the tangled mass of solid waste that caused the initial problem remains in the sump where it must be addressed. Otherwise, it will likely grow and cause additional problems.

back most solid chunks and fibrous material. The relatively solids-free water then continues to a holding tank. When the control system senses that the tank is nearly full, it turns on pumps that reverse the flow back through the screening chamber. Check valves prevent flow back through the inlet pipe, so that the water, which is once again carrying the solid materials in suspension, is forced through the outlet piping, downstream to the next stage in the wastewater processing cycle. Since the pumps only have to handle pre-screened water, there is much less risk that they will become jammed with SPECIAL SOLUTIONS solid materials.

Because the solids separation system is largely self-cleaning, due to the reverse flow cycle, these units require relatively little maintenance. When work is required, the separation chamber and booster pumps are conveniently located on the exterior of the unit where access is easy. In addition, since the pumps and impellers can be optimized for hydraulic performance, these units can deliver significantly lower energy costs. They are especially useful in situations where flow volumes are low, head requirements high and the likelihood of encountering significant amounts of solid and fibrous wastes is also high. These conditions can often occur in semi-rural areas and vacation properties. Michael Blundell is with KSB Pumps Inc. For more information, visit www.ksb.ca

Alternative COD monitoring tool helps pulp and paper operations By Stephanie Horner, Maggie Grierson and Robert Menegotto

Recalcitrant COD is composed of organics that do not readily oxidize under biological conditions and are problematic in pulp and paper effluents. © Igor Groshev – stock.adobe.com


he EUREKA Cluster for Water provides transnational collaboration for innovative projects in water and environment. “Novel Concepts for the Reduction of Recalcitrant COD in Water Intensive Industries” is a recent project that focuses on the pulp and paper industry. (www.acqueau.eu) Recalcitrant COD can also be referred to as hard COD in some industries. It is composed of organics that do not readily oxidize under biological conditions and are problematic in pulp and paper effluents. MANTECH’s photoelectrochemical Chemical Oxygen Demand (peCOD) method was used to evaluate COD reduction by new technologies used at various stages of the pulp and paper wastewater treatment process. The peCOD method eliminates the use of mercury, dichromate and concentrated acid, and generates COD results in 15 minutes. The core of the peCOD

42 | February 2017

technology utilizes the high oxidation potential of UV irradiated TiO2 nano-particulates to fully oxidize all present species. The testing range is 0.7 mg/L-15,000 mg/L of COD. Incorporating dilution can extend this range. The peCOD method is approved by the Ontario Ministry of the Environment and Climate Change (MOECC Method E3515). It is also an approved ASTM International method for drinking water treatment plants (raw and treated water). Through the pulp and paper project, MANTECH is working with a variety of international research partners to evaluate and verify the correlation of peCOD to conventional dichromate COD. FPInnovations, located in PointeClaire, Quebec, is one of the Canadian research partners working with MANTECH. FPInnovations compared MANTECH’s

automated L100 and online P100 peCOD analyzers to the conventional dichromate testing method. A variety of samples from both kraft and mechanical pulp mills across Canada were collected and sent to their lab for analysis. Both filtered and unfiltered samples were run in triplicate for COD, on each of the peCOD models, and using the dichromate method. The automated L100 peCOD is a benchtop model for analyzing multiple grab samples. Sample preparation, such as filtering, is completed by the operator, with the remainder of the peCOD analysis running unattended. The online P100 peCOD is fully automated to analyze one sample stream at a time. It can filter, and connect directly to Supervisory Control and Data Acquisition (SCADA) system. Both systems were operated at FPInnovations to verify their variability and robustness, using an abrasive sample matrix.

Environmental Science & Engineering Magazine

A recent report from FPInnovations concluded that solids in wastewater effluent do not significantly contribute to total COD. From a variety of primary and secondary treated effluent samples, including both kraft and mechanical pulp mill operations, COD from solids typically represented less than 2% of the total. This will not impact the overall COD result obtained with the peCOD, as the technology requires sample filtering of at least 50 ¾m. A strong correlation between the standard dichromate and peCOD method confirmed this with r2 values ranging from 0.92-0.99 on both peCOD models. On average, where differences existed, the peCOD method gave slightly higher COD results than dichromate. This could be due to the peCOD more effectively oxidizing recalcitrant COD present in treated effluent samples. Results obtained from FPInnovations were also confirmed by two research partners in Finland that are part of the Novel Concepts for the Reduction of Recalcitrant COD in Water Intensive Industries project. In Finland, research partners are utilizing all peCOD models in two separate pulp and paper labs. They are also using an online P100 peCOD, installed at the influent stage of a mechanical pulp and paper mill’s wastewater treatment plant. With the data currently being collected

MANTECH's automated L100 peCOD analyzer.

from all pulp and paper research partners, MANTECH is working on the next generation online P100 peCOD analyzer that has the capability to operate remotely through a web-based platform. Outside of the recalcitrant COD project, there is a full scale pulp and paper facility utilizing the peCOD to minimize cost and increase performance. A Chilean mill laboratory has installed a peCOD unit, which provides results to process engineers 2.5 hours faster than the dichromate method. This led to a reduction in hypochlorite used for bleaching, no loss of product quality, lower organics in the waste water plant and reductions in chemical and energy use for treatment. The total savings over 12 months was $3 million

dollars (US). The return on investment on the peCOD unit was a mere three days.

CONCLUSIONS The strong correlation between peCOD and conventional dichromate suggests there is potential for peCOD as an online monitoring tool to help both in-mill operation and wastewater treatment optimization. It is also a safer, faster, and greener procedure to perform than conventional dichromate testing. Stephanie Horner, Maggie Grierson and Robert Menegotto are with MANTECH.

Thermal flow meters chosen for WWTP cogeneration system By Ray Heulitt and Art Womack


large regional wastewater treatment Waste and natural gas blended system. plant recently launched a project to build a cogeneration waste-toenergy project. It was intended to power a portion of its operations, including a new ultraviolet disinfection system, which was needed to help the plant meet discharge limits. The plant performs primary, secondary, tertiary and sludge treatment processes and serves over 250,000 residential customers and 3,000 industrial and commercial customers. A maximum peak flow of 380 ML can be processed daily. The facility’s management team wanted to achieve both environmental and cost savings goals with the cogeneration system. Four large 1.5 MW cogeneration power production engines, fueled in part by digester gas, were installed. Large gas reciprocating engines, like these, have high electrical efficiency rates with a relatively Installed FCI ST98 thermal mass flow meters. low environmental impact. By providing energy directly from the load source for use in the plant, there is very little energy loss due to transportation and distribution. The team chose to power the engines with natural gas. This would sustain the BTU levels required by the engines in the event that digester gas production was too low. The blended waste gas and natural gas system was necessary because the plant didn’t always produce enough waste gas to operate at least two of the four cogeneration engines at 70% of the load needed for plant operations.

CONTROL PROBLEM The team needed a solution to meet the cogeneration engines’ control system requirements for independent flow measurement of both the digester gas and the natural gas lines, in order to blend the mixed gas properly. To minimize training and service/support costs, they wanted to use the same flow meter technology from a common vendor for both the digester 44 | February 2017

150 mm lines and measure a flow rate of up to 14 Normal Cubic Metres per Minute (NCMM). Temperature conditions ranged from 10°C - 38°C at a pressure of 4 bar[g]. The flow meters needed to work accurately at a pipe straight-run of 120 pipe diameters.

SOLUTION After consulting with the applications team at Fluid Components International (FCI), treatment plant engineers chose the FCI Model ST98 thermal mass flow meters. These were then installed on both the digester gas and the natural gas lines at the plant. The flow meter’s standard 4-20 mA analog output of flow rate was wired into the wastewater treatment plant’s four-engine control system. FCI’s thermal dispersion sensing technology provides direct mass flow measurement. It places two thermowell protected platinum resistance temperature detectors (RTD) in the process stream. One RTD is heated while the other senses the actual

process temperature. The temperature difference between these sensors generates a voltage output, which is proportional to the media cooling effect and can be used to calculate the mass flow rate. An additional benefit of FCI’s direct

mass flow sensor technology is that the meter also includes built-in temperature compensation to ensure repeatable and reliable measurement even in extreme environments, such as those found in outdoor wastewater treatment plants. This temperature compensation technology adjusts automatically for accuracy to changes in seasonal temperatures, such as cold winters, hot summers and periods of high humidity. The ability to measure both digester and natural gas with the same meter has allowed for significant cost savings. The cogeneration system is now running at the highest level of efficiency, in large part thanks to flow meters. Ray Heulitt and Art Womack are with Fluid Components International.

Operators turn to alternative technologies to deal with ‘flushable’ wipes By Kevin Bates


n the past 15 years, disposable wipes have found their way into our daily routines. Once the industry began marketing them for household cleaning and “flushable” bathroom use, their sales and adoption steadily increased. When the wipes industry began pushing their products into the marketplace, they were simply resized baby wipes made of a stretchy synthetic material called spunlace, which resisted breaking apart in water by design. The wipes you pick up in the store today, however, are likely made of cellulose substrate, which disperses only slightly better than spunlace. It still requires intervention to fully break down. What this means is that the wipes flushed down the toilet don’t break apart like toilet paper, and won’t unless they are mechanically agitated.

In the consumer’s mind, if something has “yucky stuff ” on it, then into the toilet it goes. The sewer professional’s hope is that the treatment plant’s headworks screens can deal with the debris once it arrives. The reality is that the disposed-of wipes often do not even have a chance to reach the screens, before they weave together in the collection systems and clog pumps, valves and pipes. In recent years, large cities have reported “fatbergs” in their systems. These are balls of fats, oils and greases that have congealed with sanitary items and wipes to block the pipes.

LABELS AND LAWS The ultimate solution to the “war on wipes” is to keep them from finding their way into the waste in the first place. This means educating the public and changing their behaviour. Many municipalities and WIPES IN THE WASTE STREAM nonprofit groups have taken on public With the flood of wipes products being awareness campaigns, including humoremployed in households and businesses ous commercials and parody game shows, Disposed-of wipes often weave into massive around the world for myriad cleaning and about what can and can’t be flushed. ragballs in collection systems, clogging pumps, hygiene purposes, toilets have become the Unfortunately, public outreach has proven valves and pipes. natural trashcans for these used products. to only have a temporary effect on the

amount of debris flushed into the system. So, some cities and industry officials are trying legal tactics to combat the wipes epidemic. New York City, for example, is introducing a bill that would fine any store selling wet wipes that don’t comply with stiff new regulations. Those regulations include strict limits on which products non-woven manufacturers can label as flushable. The International Organization for Standardization (ISO) is also tackling the term “flushable,” and is currently working to develop an international standard for labeling wipes. Manufacturers would only be able to add “flushable” to their labels if the wipes endured and passed specified flushing tests. While these steps will help with wipes specifically designated safe for flushing, the disposable wipes problem is much bigger than just a label. A study conducted by the Maine Wastewater Control Association found that 90% of the products

pulled from the waste stream during their tests were never designated as flushable in the first place. Flushability standards, like those proposed by ISO and New York City, will only address 10% of the problem typically found in today’s sewage.

CHALLENGE OF MODERN SEWAGE Pump stations and collection networks are seeing a new kind of sewage-filled debris that they were never designed to deal with. The heavy solids loading in today’s sewage easily overwhelms traditional pumps, including solids handling pumps, and can create problems for size-reduction equipment, like sewage grinders. The Santa Margarita Water District in California has firsthand experience with today’s more challenging sewage. When the Santa Margarita reclaimed water facility installed a CMD singledrum Channel Monster® sewage grinder from JWC Environmental in the 1990s, they were sure they’d put in place adequate

pump protection against tough debris for years to come. For many years, that proved true, until the early 2000s when the composition of influent became heavily loaded with disposable wipes. The ever-increasing number of wipes and rags in the wastewater stream began proving too difficult for their original Channel Monster to handle. While it would process the waste, the wipes would become long, stringy bits of debris that would twine together and build up in the wet well. “We have a bank of four VFD controlled pumps at the facility. Typically, we run an alternating cycle, with two pumps operating and then switching to ensure equal runtime,” said Ron Johnson, the senior supervisor at the facility. “This operating sequence, with the pumps modulating around 50 Hz, kept up with plant flow requirements. But, starting in about 2012, the pumps would begin to lose efficiency as the wipes’ loading increased. We would have to run all four pumps to

Pump stations and collection networks are seeing a new kind of sewage-filled debris that they were never designed to deal with. maintain plant production. Once they reached 60 Hz, we would need to shut down the plant to derag the pumps.” The deragging process started to become necessary every two to six weeks. It required two operators for about two hours each time. And, due to some aging isolation valves that leaked, the plant needed to be entirely shut down during deragging. These unplanned shutdowns were costing the district an acre-foot of reclaimed water production per month. Labour costs added up to about $15,000 per year.

HANDLING WIPES IN THE WASTE STREAM Since the likelihood of wipes being

eliminated from our waste streams anytime soon is not high, operators are turning to alternative technologies to address the challenge. One proven strategy is preconditioning all of the solids before they reach the pumps. Grinding wipes along with other waste before it gets to the pumps has shown to be a very effective method for preventing damage, eliminating risks, and reducing the time and energy costs associated with clogging. Grinding wipes, along with other solids, reduces the matter to a size that can pass through pumps and collections systems without reweaving. Dual-shafted grinders, which use low-speed, high-torque grinding to break down troublesome solids, are one of the

Environmental Science & Engineering Magazine

most effective means of shredding wipes. With two rows of hardened steel cutters that rotate toward one another, cutter teeth will actively grab solids and pull them through the cutter stack, shredding the debris into smaller pieces. JWC has introduced Wipes Ready Technology for their Muffin Monster models, which use new cutters, screening drums and operating technologies to improve debris capture rate and cut wipes into smaller squares. Testing showed that these enhancements eliminated the formation of long strips and rag balls.

SOLUTION FOR A WATER DISTRICT The Santa Margarita Water District began looking for a long-term solution to their ragging problem, since both the cost and safety concerns were not sustainable. “We considered changing out the current pumps to a new set of chopper pumps. But, this option would cost $100,000 and wasn’t really going to solve the problem,” said Johnson. “We still needed to maintain our inlet Channel Monster to take care of


larger debris the pumps couldn’t handle.” Johnson ultimately decided to upgrade the facility’s Channel Monster to a new Wipes Ready perforated drum configuration. The coil drums of the original Channel Monster were designed to capture large debris and push it into the grinder’s cutter stack for size reduction. “This upgrade cost significantly less than purchasing a whole new set of pumps,” Johnson said. “Plus, this is a solution that will completely eliminate the pump clogging problems we were having.” Since the new Channel Monster drums were installed in 2014, the district has had zero pump-clogging issues at the facility, and has returned to using two pumps at a time instead of all four. Pumping energy costs have decreased $78,000 per year and manual pump deragging has been eliminated. Kevin Bates is with JWC Environmental, who are represented in Canada by ACG Technology Inc.

Agricultural lands can adversely impact groundwater quality by increasing the levels of certain chemicals such as nitrates. © Leonid Eremeychuk – stock.adobe.com

Monitoring nitrate levels in groundwater vital to protection of public health By Kerim Kollu


onpoint sources of pollution, such as agricultural lands and fertilized lawns and gardens, adversely impact groundwater quality by increasing the levels of certain chemicals and nutrients such as nitrogen. The main concern about nitrogen-containing compounds is nitrate, due to its high prevalence in fertilizers. Because nitrate is highly soluble it tends not to get filtered out like other contaminants, as the water seeps through soil layers down to the groundwater level. How much nitrate reaches the groundwater zone from agricultural applications is governed by varying levels of crop watering and irrigation, as well as changing rainfall levels. Other sources of nitrates in groundwater are unmaintained septic tanks and leaking sewer pipes. It is therefore important to monitor nitrates as often as possible in groundwater, since levels can be difficult to predict and may 50 | February 2017

potentially indicate presence of other contaminants.

HEALTH EFFECTS OF NITRATES IN DRINKING WATER When nitrates enter the bloodstream, they reduce the ability of red blood cells to carry oxygen, which has serious health effects. This is particularly important for infants under the age of six months where excessive levels of nitrates lead to methemoglobinemia, or “blue baby syndrome.” Prevention of the blood from providing enough oxygen to cells in the body gives the skin a characteristic blue colour, and leads to very serious health problems. Studies have indicated that people who have heart or lung disease, certain inherited enzyme defects or cancer, may be more sensitive to the toxic effects of nitrates than others. In addition, some experts believe that long-term ingestion

of water high in nitrates may increase the risk of certain types of cancer. For these reasons nitrate is a regulated water quality parameter. Smart water management requires reliable and quick detection of nitrates to allow water utilities to provide a timely response in order to better protect public health.

PROBLEMS WITH ANALYSIS When nitrate analysis of water involves sending samples to a third party laboratory, certain issues are encountered. Laboratory methods are lengthy and expensive, and samples may be compromised during transportation. The length of time it takes to report back to the client inhibits the usefulness of the information, and the extra costs associated with laboratory testing reduce the frequency of sampling. Monitoring of nitrates in drinking

water on-site and in real time is straightforward with the use of Real Tech’s nitrate analyzers. Nitrates have a characteristic absorbance curve in the UV region which makes them an excellent candidate for detection by spectrophotometry. However, organic compounds, nitrites, iron, manganese and suspended solids also absorb UV light and interfere with nitrate detection. To compensate for these potential interferences, Real Tech’s nitrate analyzers are equipped with proprietary algorithms that use absorbance information from strategically selected wavelengths of light. In addition, the Real Clean automatic cleaning system ensures that the sensor is kept free of fouling and drift. This saves time and labour as manual cleaning and calibration are not typically required, while accurate readings are maintained. One water utility, that provides groundwater to residents from hundreds of wells in a rural area, requires online monitoring to ensure that nitrate levels are maintained in compliance with drinking water regulations. Some of the wells have high nitrate concentrations in the water, while others do not. The water utility manages this situation by blending waters from clean wells with nitrate contaminated wells to ensure that the finished product water has nitrate levels well below the regulatory limit of 10 mg/L NO3 as N. Before the treated water is pumped into the distribution network, it is monitored for pH, residual chlorine and nitrates. Real time monitoring is a much needed decision-making tool for this utility as it provides the required water quality information within minutes and allows for immediate action to protect the public from exposure to high levels of nitrate in their drinking water. The utility participated in a four month study of Real Tech’s nitrate analyzer, to test accuracy and demonstrate the effect of fouling. Results showed it maintained a steady baseline close to 0 mg/L, thanks to the automatic cleaning system, and was able to accurately report nitrate events.


CONCLUSIONS Real time monitoring is an excellent tool for ensuring public safety by providing vital information in a timely manner. It provides data, both spatially and temporally, by continuously analyzing the water on-site, as opposed to laboratory testing methods which analyze small volumes that are widely spread over time. This allows for better

trend and event monitoring, optimizing the decision-making processes. Finally, real time monitoring can be used for optimizing the water blending process, saving energy and costs in water stressed regions. Kerim Kollu, PhD, is with Real Tech Water. Email: kerim@realtechwater.com

Anaerobic reactors for cold climates must be specially engineered By Shannon Grant


naerobic reactors for cold climates must be engineered to mitigate low ambient temperatures. Fluctuating temperatures either stimulate or inhibit microorganisms, affecting biological treatment performance and biogas generation. In the microbiological world, temperatures ranging between 40°C – 60°C are referred to as thermophilic; temperatures ranging between 20°C – 40 °C are known as mesophilic. Thermophilic methanogenic bacteria are much more sensitive to temperature fluctuations. This means they require a longer period to adapt to changing temperatures to achieve maximum biogas production. Scientific research suggests that thermophilic biomass is more sensitive to process upsets. This sensitivity, plus the additional energy required to maintain the higher temperature, may not be worth the increased biological activity. Mesophilic bacteria, on the other hand, can endure wider temperature fluctuations without significant impact on biogas production.

INSULATING FROM THE GROUND UP In winter, heat naturally wants to transfer from warm reactors to colder surroundings. Seasonal variations in air and soil temperatures affect this significantly. The depth to which the ground freezes depends on how cold the air temperature is, how long temperatures stay below freezing, and the depth of the insulating cover (such as snow). If there is persistent snow cover, the ground may only freeze to a few centimetres below the surface. Long cold spells with no snow cover can cause the ground to freeze much deeper. Heat loss must be minimized to maintain proper operating conditions in biological systems. Without the right 52 | February 2017

This meant that process stability and the ability to handle variations in hydraulic and organic loads were important factors when selecting an anaerobic digestion system. The mill also needed a wastewater treatment solution that could stand up to cold temperatures. From October to April, northern Alberta experiences freezing temperatures and many winter days do not rise above 0°C. Since both the wastewater treatment process and biogas production are temperature dependent, it was important to find the right solution. With assistance from the Climate Change and Emissions Management Corporation and the Government of Alberta, Slave Lake Pulp embarked on a biomethanation and power generation project that would anaerobically digest pulp mill effluent to generate biogas to be used as green energy.

the mesophilic range. The system includes an insulated cover to provide thermal protection to aid in anaerobic digestion. The cover captures methane that is produced during the process. Biogas generated in the system migrates to the reactor cover’s perimeter, where blowers pull it through the scrubbing system, boost the pressure, and transmit the scrubbed biogas to a set of three 3 MW gensets designed for biogas applications. This methane-rich biogas is used to reduce the mill’s dependence on fossil fuels.

THE RESULTS The wastewater treatment and wasteto-energy system is helping the mill improve the quality and consistency of final effluent and biogas production, despite cold temperatures.

Analyzing wastewater digester heating requirements By Ivan Drako, Ron Cariglia and Sean Hutchinson


he anaerobic digestion process that maintains suspended-growth treatment for the stabilization of organic materials and biosolids is widely utilized as a method for handling of solids produced from various treatment operations at a wastewater treatment plant. This is a continuation of a previous article in the September/October 2015 issue of Environmental Science & Engineering Magazine (www.esemag. com/digester-heating), which presented an analysis of anaerobic digester heating requirements. Conclusions summarized in the previous article stated that approximately 75% – 95% of the total digester heat loss is attributed to the non-insulated below grade digester structure. If the below grade structure of the digester had been furnished with thermal insulation, a reduction in the heat loss might have been in the range of 35% – 40% of the total heating needs. These conclusions were not reviewed in detail previously. This article is an attempt to present several aspects of digester heating requirements, when the below grade structure is furnished with thermal insulation. For these analyses, a primary digester with similar physical dimensions to those in the first article is utilized. The 33.5 m diameter digester has a fixed concrete roof and conical floor slab, each connected by 12.2 m high side walls, with an operating liquid depth of 10.8 m. The above grade wall height and below grade wall depth of the digester structure is approximately equal. The above grade structure has been thermally insulated, and the below grade has thermal insulation installed to the frost line depth only. The following assumptions were applied: • For the analyses, the digester structure was divided into areas with similar heat transfer characteristics, including the roof, above grade walls, below grade walls and buried floor slab. • The outdoor temperature was assumed to vary from -35°C – +40°C for winter and summer, respectively. • The soil temperature is assumed steady at any depth of the buried digester structure located below the frost line. 54 | February 2017

• The sludge recirculation pump flow is assumed to be constant over the entire review period. • For mesophilic digestion, sludge temperature is being maintained between 36°C – 38°C. Target temperature is achieved by transferring heat from hot water to sludge via a heat exchanger, followed by recirculation of the heated sludge back to the digester tank, in order to prevent stratification of the solids and to maintain homogeneous temperature in the digester reactor. • For these analyses, the thermal characteristics of rigid cellular glass insulation were used. Insulation thickness considered for the analyses varied from 25 mm to 100 mm (in 25 mm increments) or as a combination of different thicknesses applied to below grade structural elements.

The heating requirements of the primary digesters at Toronto’s Ashbridges Bay WWTP were recently examined.

Environmental Science & Engineering Magazine

ANALYTICAL RESULTS Thermodynamic analyses were conducted on the digester structure, using several different thermal insulation scenarios, including the installation of thermal insulation on the digester below grade walls only, and also on the below grade walls and floor. Heat losses calculated for each season’s temperature and for each below grade insulation scenario were presented as sludge temperature rises that should be maintained in the heat exchanger, in order to compensate for heat dissipation. Figure 1 presents the overall digester temperature rise required to be maintained for various scenarios of thermal insulation applied to the below grade structure, including insulation of the buried walls only and also the buried walls and floor. For comparison purposes, and in order to understand heat loss trends, the digester temperature rise for the existing non-insulated below grade structure scenario was also provided, i.e., a “no insulation” scenario. Heat loss distributions between the above grade and below grade structures of the digester were estimated for various thermal insulation scenarios of the buried digester structure. The chart shows variations of the below grade structure heat loss as a percentage of total digester heat loss throughout the year. (See Figure 2) Overall heat loss reduction as a result of the insulation of the digester’s below grade structure was calculated and is presented in Figure 3. The chart shows the heat loss reduction as a percentage of the total heat demand needed to be maintained throughout the year for a digester with a “no insulation” below grade structure. Heat demand of the existing “no insulation” scenario equals 100% for each scenario and is not shown in the chart. In order to demonstrate practically heat demand reduction as a result of thermal insulation applied to the below grade structure, the mitigated heat loss (via insulation) was converted to the volume of natural gas that would have been needed to operate the digester

boiler. This was for the generation of hot water as the energy source for heating digester sludge in the heat exchanger. Reductions in the major combustion products emitted to the atmosphere as a result of less boiler operation were also estimated.

CONCLUSIONS The results are useful for new digester design and operation purposes. • Digester reactor heat loss decreases if thermal insulation is installed on the buried structures. It is obvious that the more area of the digester structure that is thermally insulated, the less heat dissipating outwards occurs. • It appears that the insulation thickness is a secondary factor and less significant for overall heat loss reduction than the extent of insulated area of the buried surface. For example, a 25 mm thermal insulation applied to the entire below grade structure provides substantially

more reduction of overall heat demand than 100 mm of insulation applied to the buried walls only. • Regardless of year-round variations of the outdoor temperature, insulation applied to the buried structures provides constant heat loss reduction. • Cost savings presented are calculated based on fuel savings. By operating the boiler for lower heat generation, the life of the equipment may be extended, and there will be a reduction in maintenance costs. If there are several digesters at a plant (usually located close to each other), a smaller boiler may be designed and installed, providing some reduction in capital cost. (See Table 1) • Combustion of reduced quantities of natural gas will also result in reduced GHG emissions, including carbon dioxide and water vapour. Other combustion products, such as particulates, carbon monoxide, sulphur dioxide and oxides of nitrogen, will also be reduced.

• The estimated payback period (based on fuel savings) for cellular glass thermal insulation installed on the below grade structure of the digester may be in a range of 8 – 12 years, depending on site conditions, digester design and thickness of insulation. The analyses presented should be considered primarily for the design and construction of new digesters. Upgrading existing digesters with thermal insulation installed in the below grade structural elements, may be not cost-beneficial. Ivan Drako, Ron Cariglia and Sean Hutchinson are with WSP.

Effectively using BAF technology in cold climates for high level nitrogen, TSS reduction By John He, Glenn Thesing, Hong Zhao, Rich DiMassimo, Luke Wood, Louis Ortenzio, Mark Drake, Mathew Edds, Meg Hallowed and Pia Prohaska


iological active filters (BAFs) are the most successfully and widely used biofilm-based nitrification or nitrification and denitrification system for simultaneous NH4-N oxidation, NOx-N reduction, and suspended solids removal through the media bed. BAFs, operating either in down-flow or upflow hydraulic conditions, have evolved from a biological nitrogen removal (BNR) treatment option to a fully mature and accepted biological wastewater technology. The key distinguishing characteristic of the BAF process is that the microorganisms live in a biofilm attached to a media surface, rather than being freely suspended in the wastewater. The solid surface is fixed in space with the wastewater flowing over it in media beds. The media bed has a very high specific area (> 1,000 m2/m3) and relatively low void space (35% – 40% of porosity). This allows the process to develop and maintain a large biomass population per unit volume for biodegradation of carbon, ammonia and nitrate. This ensures that filtration and clarification can achieve very low effluent TSS (less than 10 mg/L). Hydraulic retention times (HRTs) can be extremely low when support media of high specific surface area are utilized. For example, both downflow with sunken media and upflow with floating media, BAFs with a specific surface area greater than 1,000 m2/m3 can give HRTs of less than two hours for complete BNR. The biofilm-based BAF process has a few distinct advantages over conventional activated sludge (CAS) technology for nitrogen removal. Accumulation of biofilm attachment on media surface 58 | February 2017

eliminates volume constraints imposed by a settler, so the physical footprint is significantly smaller than a clarifier-coupled CAS system. Simultaneous ammonia removal or NOx-N reduction on media surface, with TSS removal through pores and interstitial void spaces in the media bed, eliminates the need for a separate liquid-solids separation unit. The presence of a large population of biofilm prevents washout of microorganisms. This allows substantial BNR even at HRTs well below those that would cause washout in a CAS bioreactor. Thus, the performance of BNR removal is always guaranteed, regardless of water temperature. Finally, nitrogen stripping and re-oxygenation of mixed liquor prior to entering the secondary clarifiers are not required, so re-aeration is not mandatory for the tertiary post-denitrification system. BAF technology has been successfully in use for at least two decades for BNR. But, it is commonly believed that it is not possible to achieve ultra-low

substrate concentrations, especially ammonia and nitrate concentrations in the effluent, due to the mass transfer limitation across the mass transfer layer and within biofilm. Design, upgrade, and successful operation of complete nitrogen removal to achieve less than 1.0 mg/L TN, with HRTs ≤ 2 hours in cold climates (≤ 10°C), has not been previously demonstrated in the field. Three plants were used in a recent study. Plant A was originally a secondary carbon removal biological activated sludge plant that had to meet total nitrogen (TN) limits of 3.0 mg/L on an annual average basis and 2.0 mg/L over the summer months. To help ensure that the stringent TN requirement was being met consistently, Plant A commissioned a full scale Kruger tertiary nitrification and denitrification (N-DN) BIOSTYR® system in August 2006. The system was designed to treat 12 MGD secondary effluent to achieve a TN concentration less than 2.0 mg/L and 3.0 mg/L for summer and winter, continued overleaf...

Does primary treatment have to take up so much space? Traditional primary wastewater treatment has required large, energy-hungry settling tanks, but this need not be the case. Technological advancements now mean that the same capability can be achieved in a much smaller footprint and at a much lower energy requirement – freeing up space and cutting costs.

respectively, in tertiary effluent. The influent wastewater temperature typically varies from 7°C – 20°C. Plant B was originally constructed in the 1950s and was facing the challenge of meeting its permit for total suspended solids, carbonaceous chemical oxygen demand, ammonia nitrogen, and TN. To address this challenge, Kruger’s tertiary N-DN BIOSTYR was chosen. The system was designed to treat 53.6 MGD of secondary effluent from the existing high pure oxygen (HPO) plant to achieve advanced wastewater treatment standards and produce less than 0.5 mg/L NH4-N, and less than 1.0 mg/L NOx-N in tertiary effluent on a monthly average basis. Minimum design water temperature during the winter is 10°C. Plant C was also a secondary carbon removal CAS system with trickling filters and aeration basins. Due to short solids retention times of less than two days and low water temperatures, the

existing secondary CAS was incapable of oxidizing NH4-N and meeting the new TN limits of 3 mg/L. In order to meet the TN requirements, Plant C chose Kruger’s tertiary N-DN BIOSTYR system and upgraded its existing secondary carbon removal only CAS plant to an advanced municipal wastewater treatment plant. This provided tertiary-level BNR and TSS removal. The system was designed to treat 14.2 MGD of secondary effluent from the existing CAS plant to achieve advanced wastewater treatment standards and produce less than 3 mg/L TN in effluent, with approximately 2.0 mg/L of the total represented by refractory dissolved organic nitrogen (RDON).

At temperatures around 20°C, the NH4-N removal rate was directly proportional to applied NH4-N VLR, with applied NH4-N VLR less than 55 lb NH4-N/1,000 ft3/day. In these ranges, the NH4-N removal rate increases as applied NH4-N VLR increases, and it is a first order reaction with respect to applied NH4-N VLR. The applied NH4-N VLR cannot be increased indefinitely. At a temperature equal or less than 10°C, once applied NH4-N VLR exceeds the 40 lb/1,000 ft3/ day, the NH4-N removal rate has reached NITRIFICATION PERFORMANCE a plateau.

NH4-N concentration. But rather, it is limited by the rate of oxygen transfer to the biofilm.

DENITRIFICATION PERFORMANCE Operation and performance guarantee data from Plants A, B, and C also indicated that denitrification performance is good and consistent for post-denitrification, as long as the flow distribution condition is acceptable; sufficient external carbon source is available; and/or unexpected media bed clogging does not occur very often. HRTs in the post-denitrification BAF can be as short as 20 minutes. In addition, eliminating oxygen transfer relieves the biggest limitation on the sludge volume loading rate (SVLR). Thus, SVLR can be much higher than for aerobic biofilm processes. The fullscale results from Plants A, B, and C indicated that monthly average NOx-N concentration has been consistently lower than 0.5 mg/L at applied NOx-N

Edmonton evaluates LID stormwater management in cold climate conditions By Xiangfei Li, Kerri Robinson, Danlin Su, Ross Bulat and Andrew Liu


ow impact development (LID) is a stormwater management and land development approach that mimics the natural hydrological cycle to manage stormwater at its source(s). Bioswale LID features have been increasingly applied in green field development and redevelopment to treat stormwater and enhance aesthetics of the communities. Bioswales are open channels with dense vegetation specifically designed to attenuate, treat and convey stormwater runoff. Stormwater volume and flow rate are reduced as the water moves along bioswales. Contaminants are settled, filtered, absorbed and/or biodegraded as the water slows down and percolates through the vegetation layer into the ground. Bioswales can green a community, improve air quality, provide wildlife habitat, and contribute to flood mitigation. Bioswales are being applied in Edmonton as part of the City’s LID implementation plan and environmental initiatives. The City promotes bioswale application and has developed design guidelines and provided training to LID practitioners. The use of bioswales is encouraged but not yet mandated. For them to become the norm, further understanding of how to address cold climate challenges is critical. The City keeps track of bioswale facilities, conducts demonstration projects, and monitors their performance to understand what would and would not work in Edmonton’s cold climate conditions. The City maintains an LID facility inventory map that includes seven types of LID features installed around Edmonton. Explore the map and LID features at www.esemag.com/bioswale-edmonton. Bioswales in different land use settings were inspected, including parking lots, middle of roadways, and around buildings. Properly locating bioswales with consideration of traffic and snow removal/ 62 | February 2017

storage is important for the success of the bioswale application. Bioswales located along a bus route faced the most challenges related to snow plowing and storage. This is particularly important in a municipality like Edmonton, where winter conditions necessitate the extensive use of street sands along arterial roads and bus routes.

FLOATING MULCH Mulch plays an important role in plant health and stormwater water quality treatment. It can prevent weeds, keep moisture in the soil, and strain pollutants in stormwater. On the other hand, mulch was observed to float in the channel of a few bioswales after storms. Mulch is a landscaping product that is not typically considered in drainage designs. Specifications rest with landscape architects by default. It is therefore important that landscaping architects understand the functions and limitations of mulch related to its role in LID facilities. Mulch should be tested in water before being installed due to the lack of mulch specification for LID application

and field experience.

FLOW BYPASS Field inspections observed that flow bypassed curb-cut inlets due to improper grading and/or overgrowth of grass that can block flow coming into bioswales. This can be a design or construction issue. SIDE SLOPE INSTABILITY Steep side slope and lack of energy dissipation can cause side slope instability. PHYSICAL DAMAGE Parking lot bioswales accepting sheet flow are prone to vehicle damage. Curbs or chains around the bioswale should be considered to protect the bioswale facilities. In addition, snow should not be stored on a bioswale unless the facility is specifically designed to take it. Sand and gravel applied during winter maintenance can clog the soil mix of the bioswale during snowmelt and reduce its permeability. This can in turn cause ponding during storm events. Salt in the snow can harm plants and vegetation in the bioswale. To mitigate

Environmental Science & Engineering Magazine

snow impact, designers need to properly size the bioswale and locate it so that there are other spaces left for snow storage. Prioritizing street sweeping operations in areas upstream of bioswale facilities prevents highly concentrated sediments and sand from entering, avoiding potential soil clogging issues.

SEDIMENTATION CONTROL DURING CONSTRUCTION Sedimentation control is critical to achieving the designed infiltration rate of bioswales. Field observations noted that bioswales on public lands were generally protected from sediments released as a result of construction activities. Bioswales located in the middle of the road in a greenfield development faced the most challenges because there are typically multiple contractors and home builders working in the stripped catchment area. It takes years for full build-out to occur and for the catchment areas to be completely

stabilized with vegetation.

SEDIMENTATION CONTROL POSTCONSTRUCTION A common issue in established bioswales is the accumulation of sediments around bioswale inlets or even caking on the bottom of the facilities. Post-construction sediment control is an integral part of maintenance that affects the long term health and functionality of a facility.

RECOMMENDATIONS Based on monitoring results and field inspection information, future work to improve bioswale implementation should include the following: • Start to clean up sediments accumulated around the inlets or in the bioswales. • Enforce implementation of sedimentation control measures and reporting and include reports on sedimentation control LONG TERM MAINTENANCE into project acceptance inspection.

Using geothermal energy for heating and cooling could drastically cut GHG emissions By Bill Eggertson


ccording to the federal Comprehensive Energy Use Database, Canada consumes 8,707 petajoules (PJ) of energy each year, which is equivalent to 2,400 billion kilowatt-hour. Of this total, the vast majority involves the combustion of natural gas, oil, propane, diesel or other fossil fuels which emit the most greenhouse gas (GHG). Until now, discussion over how to constrain the rise in temperature to less than 1.5°C has focused on increasing our reliance on the 20% of energy that is transmitted as electricity. Efforts to eliminate coal-fired power and to increase output from solar panels and wind turbines have resulted in a greening of our grid. If we avoid the debate over methane emissions from large hydro dams, ignore that natural gas emits half the GHG of burning coal, and sidestep the sensitivity of including nuclear in the “clean energy” category, the overall policy target is clear: electrify

everything. The climate change plan in Ontario, which generates 60% of its electricity using nuclear power, has set the scene for large amounts of power to fuel electric vehicles and to displace natural gas in space heating. With two-thirds of Canada’s power currently coming from large hydro-electric facilities, and construction underway from Muskrat Falls in the east, to Site C in the west, our national commitment to electrification will not dim anytime soon. There will be significant challenges to increasing generation capacity and to increasing the share from non-combustion sources. This will result in opposition from western provinces whose economies are based on fossil fuels, and complaints that renewable energies cannot be turned on and off, and can destabilize the grid. Industry consumes the most energy (40%) of any sector, and it will be difficult to

wean factories off combustion technologies. Transportation consumes another 30%. Solar photovoltaic systems and wind turbines can be located close to load, but it is unpopular for large generating facilities to be situated close to population centres. Much work is being done to develop a wide range of engineering solutions to reduce Canada’s GHG emissions from industrial processes and transportation. However, the third-largest energy consuming sector (27%) is buildings. Here, there is much opportunity for planners, builders and occupants to seize the potential of geothermal heating. Ground source heat pumps were highlighted as a potential silver bullet in the “trial balloon” climate change plan released by the Ontario government in 2016. They can supply 100% of a building’s space and water heating, as well as space cooling. These three uses represent 84% of the energy load in our residential sector and 69% in commercial-institutional (CI). Collectively, these consume 21% of Canada’s energy. Integrating a sustainable space conditioning technology offers the easiest solution for building owners and occupants to control costs, comfort levels and environmental footprint. A heat pump needs electricity to run compressors and pumps, but these components transfer renewable thermal heat out of the ground and upgrade it for space heating and water heating demand. In summer (or throughout the year in many CI facilities), the circuit is reversed to provide space cooling. Over the past 25 years, energy intensity in buildings has slowly decreased as insulation improves, LED lighting increases, and appliances become more efficient. But, the consumption of energy for space cooling continues to rise at double-digit levels as weather patterns change. A ground source heat pump can transfer from four to seven units of thermal

Environmental Science & Engineering Magazine

energy from the ground for every unit of electricity that is used by its working components. That net delivery (co-efficient of performance) is all renewable energy. Geothermal’s inherent energy efficiency dramatically lowers the need for new generating capacity (solar or wind, nuclear or gas) and significantly reduces infrastructure costs to transmit power from the generation site. Other benefits include complete dispatchability (it runs when you touch the thermostat), climate resiliency (tornadoes and ice storms cannot damage a buried ground loop), suitability for district heating and cooling (common in Europe), hybrid applications (such as Toronto’s deep lake water cooling), and the ability to avoid peak rates. Geothermal has been available for many years and thousands of systems have been installed in homes and offices across Canada. They are buried in over-burden or granite, sunk in harbours or lakes, used to isolate foundations from

costs can be minimized for both creation and transmission of power. With the burgeoning market in solar panels and other distributed generation, tied with the increased efficiency of battery storage, ground source heat pumps are a logical option to reduce the 500 billion kWh currently used each year to heat and cool buildings. The climate change plan in Ontario specifically states that new buildings will be required to have net-zero emission by 2030. So, gas heated homes will need to install solar panels or another carbon-offsetting option to comply. Of the total energy bill for the average home in Canada, six units are consumed for space heating in winter, two units for water heating, two units for plug load throughout the year, and a growing fraction for space cooling in summer. A geothermal home would still require two units for plug load but its efficiency means that only two units of energy would be required for all space

heating, cooling and domestic hot water demand. This is a 60% power saving. Adding solar panels to the roof would allow a geothermal house to surpass the concept of net-zero and become a “carbon sink” by emitting no GHG (in regions where the grid is used to transmit clean power). This is because it is supplying renewable energy into the grid. The primary objective of the Canadian Chapter of the International Ground Source Heat Pump Association

is to roll out a new training curriculum for dealers in the geothermal industry, with a focus on installations in the CI sector. Residential installations are relatively easy to design. Office buildings have far more variables which, if optimized, can result in higher efficiencies and lower costs. Canada’s changing climate, and the resulting changes in environmental policies to mitigate the impacts, will require an unprecedented level of commitment from all sectors. It will demand even more creativity to reach the requisite targets. While new and different sources of energy will be needed, all applications and end uses need to be re-engineered. Also, conservation and efficiency must always be at the top of the list. Bill Eggertson is with the Canadian Association for Renewable Energies.

Collecting a sample as part of Canada’s Chemical Management Plan.

How effective are WWTPs at removing harmful chemical substances? By Shirley Anne Smyth


unicipal wastewater is recognized as an important pathway for harmful chemical substances to enter the environment. In 2009, the Government of Canada’s Chemicals Management Plan (CMP) was expanded to include monitoring and surveying chemical substances in municipal wastewater treatment plants across Canada.

SAMPLING AND ANALYSIS OF MUNICIPAL WASTEWATER Sampling points for the wastewater monitoring program provide information on levels of substances in raw influent, primary effluent after physical settling of solids, and final effluent after biological treatment, phosphorus removal, filtration and disinfection. Sampling also includes primary sludge (PS), waste biological sludge (WBS), and treated biosolids, to 68 | February 2017

determine which substances partition to solids and their fate during the solids treatment process. (See Figure 1) Raw influent, primary effluent, and final effluent samples were collected as 24-hour composites from all mechanical WWTPs and lagoons where possible. Primary sludge, waste biological sludge, treated biosolids, and lagoon effluent samples were collected as grabs. Each WWTP was sampled for three consecutive days during warm and cold seasons.

ing program has generated data on a wide range of PPCPs. The results include: • Limited removal capacity by primary treatment and trickling filter treatment. Moderate removals (mean 30%) from activated sludge, biological aerated filter (BAF), and biological nutrient removal (BNR) processes. Parent compounds were removed more effectively than metabolites. A few compounds showed strong sorption to solids. • Mixed removal capacity by a membrane bioreactor plant.

tion, some by sorption to solids, and some remained in effluents. Removals higher than 80% were observed at temperatures above 13°C, hydraulic retention time (HRT) longer than 15 hours, and solids retention time (SRT) longer than six days. Removals were correlated with COD removal and degree of nitrification.

BROMINATED FLAME RETARDANTS Flame retardant (FR) residues have been measured in many organisms, human tissue, serum and milk. The polybrominated diphenyl ether (PBDE) family of FRs was heavily used in foams and household plastics. However, because of their persistent, bioaccumulative and toxic characteristics, their use was phased out from 2004 to 2013. PBDEs, along with four other brominated flame retardants (BFRs) that could become replacements in industry, were one of the first substance groups included in the wastewater monitoring program. continued overleaf...

PBDEs and BFRs were detected in all samples at levels ranging up to 1,000 ng/L in influent and 260 ng/L in effluent, and up to 6,000 ng/g in treated biosolids. They were >90% removed in all wastewater treatment processes, except chemically-assisted primary treatment where removal was 70%. Removal from water occurred through partitioning to solids, not through biodegradation, and was not dependent on temperature. Optimal conditions for removal from water were >2,000 mg/L mixed liquor suspended solids (MLSS), >9 days SRT, and >10 hours HRT. Levels of BFRs in biosolids increased due to destruction of volatile solids during anaerobic digestion, but decreased due to dilution during alkaline treatment.

BISPHENOL A Bisphenol A (BPA) is used in polymer manufacture for protective coatings on electrical and electronics equipment, and as a liner and coating in food and beverage containers. BPA is a xenoestrogen that can disrupt the endocrine system and its use in polycarbonate baby bottles has been prohibited in Canada. BPA was monitored in the same treatment systems as the PBDEs. It was always detected in influents, sludge and biosolids. It tended to be removed during biological treatment processes, with BAF, membrane bioreactor and BNR systems showing the best removal. Chemically-assisted primary treatment showed minimal removal. Better removal was observed at higher temperatures in aerated lagoons, secondary treatment and BNR treatment. Greater than 80% removal of BPA could be achieved with HRT 13 hours, SRT 7 days, and MLSS 1,600 mg/L at warm temperatures. HRT 13 hours, SRT 17 days, and MLSS 5,300 mg/L would be needed to achieve the same removal at cold temperatures. BPA was always detected in solids. Levels in anaerobically digested biosolids were higher than those in PS, WBS, alkaline treated biosolids, and aerobically digested biosolids. Partitioning of BPA from water to solids was minimal. Biodegradation under aerobic conditions was an important removal mechanism. No biodegradation appeared to occur under anaerobic conditions. 70 | February 2017

NONYLPHENOL ETHOXYLATES Nonylphenol ethoxylate (NPE) surfactants have been used extensively in cleaning products, degreasers, textile processing, protective coatings, and pulp and paper processing. In 2001, NPEs were added to the List of Toxic Substances under CEPA 1999 because of their potential for endocrine-disrupting effects. In response, Environment and Climate Change Canada required a 95% reduction of NPEs in soap and cleaning products, and processing aids in the textile and pulp and paper industries by the end of 2010. These source reductions were intended to reduce levels of NPEs in wastewater effluents. Therefore, in order to evaluate whether these actions were having the

intended effect, NPEs were monitored at participating WWTPs in 2010 and 2011. NPEs were monitored in raw influent, final effluent and treated biosolids, at warm and cold temperatures. They were always detected in influents and frequently detected in effluents. Influent concentrations tended to be higher, and removal tended to be better, at warm temperatures. NPEs were removed effectively in all processes that included biological treatment (median 91%) compared to primary treatment only (median 54%). Results showed a 98% reduction in effluent concentrations of nonylphenol from secondary wastewater treatment systems compared to previous data. NPEs were always detected in treated solids.

a 15% reduction below 1990 levels. An additional reduction of 9.8 Mt is expected to come from the Climate Change Action Plan, which will be funded by the GGRA. While applauding the Action Plan’s scope, ambition and valuable initiatives, the ECO is skeptical of its ability to produce 9.8 Mt in new reductions by 2020. The ECO found that the key proposal to subsidize electricity prices, which is projected to result in 3 Mt of GHG reductions by 2020, will not meet any of the key policy objectives for effective emissions reductions and should not be considered an acceptable use of GGRA funds. Similarly, the ECO found no evidence to support the claim that low-carbon technology adoption by industry can contribute 2.5 Mt in additional reductions.

Effectively using BAF technology in cold climates continued from page 61

HYDRAULIC LOADING PERFORMANCE For the design and operation of a BAF system, one very important constraint is the maximum HLR, since excessive headloss will occur if the BAF is operating at a higher HLR. The maximum HLR was determined based upon influent TSS concentration along with biodegradable carbon concentration, either internal (plant influent carbon) or external (exogenous carbon source). The HLR affects the operation and performance of a BAF in different ways, depending on the type of application. Generally, an increase in HLR causes increased headloss, more frequent backwashing and wasting a larger amount of treated wastewater for backwash. For a post-denitrification BAF, the more frequent backwashing due to a higher HLR has a detrimental effect on the denitrification performance. This is because of the introduction of excessive dissolved oxygen into the media bed from the air scouring process during backwash. CONCLUSIONS The experience with the opera-

tion of Plants A, B, and C supports the conclusion that BAF is an excellent technology for upgrading existing CAS systems, to either maintain nitrification at higher flow rates/loads or upgrade a CAS plant to meet new nitrification or total nitrogen removal requirements. Ultra-low substrate concentrations could be achieved in biofilm BAF systems and the performance of the system is highly consistent regardless of water temperature. Undoubtedly, BAF technology has demonstrated that extremely low effluent concentrations of NH3-N (less than 0.5 mg/L), NOx-N (less than 0.5 mg/L) and TSS (less than 10 mg/L) can be consistently achieved at very short SRTs in cold climates (less than 10°C). Finally, the results show that biological active filter technology is capable of achieving extremely low TSS concentrations with short hydraulic retention times.
