If you want to work for Bishop Water, our CEO says you need some attitude

DATE POSTED: May 9, 2023

When it comes to building a successful clean-tech company, technical skills are typically thought to be the most desirable trait for new hires. However, according to Kevin Bossy, CEO of Bishop Water, while technical skills are important, it’s heart and desire that help find new innovations and really engage with customers. Low-energy solutions are often found by those with a high-energy attitude. This philosophy has helped Bishop Water achieve extraordinary progress in developing and optimizing simple, low-energy treatment technologies.

In a recent interview on BioTalent Canada’s “The Science of Talent” podcast, Kevin discusses with host Rob Henderson about how Bishop Water’s focus on attitude has enabled the company to achieve major milestones. Over the past 15 years, the company has experienced tenfold growth, attracted and retained top talent, and commercialized industry-leading solutions.

“Having an entrepreneurial spirit, that sort of inquisitiveness, those kinds of things, in my mind are somewhat more important than the technical.”  – K. Bossy

Free up space fast in sludge storage tanks with our mobile dewatering system.

DATE POSTED: April 27, 2023

How much space is left in your sludge storage tank this spring? If it’s nearly full and seasonal restrictions or wet weather are preventing removal and land application, we have a fast and affordable way to solve the problem on a temporary or permanent basis.

Our Mobile Dewatering System (MDS) is a simple, low-energy system that enables operators to pump sludge from storage tanks into 20 m³ Geotube® units that have been set roll-off bins for dewatering and containment. This modular system enables operators to remove from the storage tank and safely store it onsite until arrangements can be made for disposal.

Low maintenance, high performance 

The system is easy to set up at any wastewater treatment plant and can be operated without disrupting ongoing plant operations. Within a few hours, this low-complexity, low-energy dewatering system can achieve dry solids as high as 15 to 18 percent. The filtrate, which seeps from the microscopic pores of the Geotube® container, typically contains TSS below 10 mg/L. As dewatering occurs, the volume of material in the Geotube® will decrease, enabling more sludge to be added until full. Once the sludge has been dewatered, the Geotube® containers can be removed to a landfill, or the solids can be removed and land applied in accordance with regional regulations. 

Design and operation of the system 

Setup is easy and a simple test will ensure the system is optimized for the sludge characteristics and the anticipated volume of material. In the initial stage, Bishop Water Technologies conducts simple jar tests and rapid dewatering tests of the sludge to determine the best polymer and optimal dose for maximum sludge dewatering in the Geotube® container. During the sludge removal process, a containerized system mixes polymer and injects it directly into the feed pipe, eliminating the need for a mix tank. The conditioned sludge is then pumped into Geotube® containers.

Lower dose, less sludge, more savings with ClariPhos™ coagulant


How much money could your wastewater treatment plant save if you could reduce the amount of coagulant you’re using for phosphorus removal by 35%? What about 50%?

It may sound impossible, but a new rare earth coagulant can help dramatically reduce annual coagulant consumption and add many other benefits such as lower sludge production, better sludge dewaterability and improved clarifier performance.

Why does ClariPhos work so well to remove phosphorus?

ClariPhos is made with the rare earth elements lanthanum and cerium, which have a very high affinity for phosphorus. These elements form a tight ionic bond with phosphorus to create rhabdophane, a dense and insoluble precipitate that settles up to two times faster than conventional Al- or Fe- based coagulants. The results are improved clarifier performance and reduced risk of carryover of suspended solids.

Up to 50% less sludge with improved dewaterability

ClariPhos forms a tight preferential bond with phosphorus, which means far less coagulant is needed to achieve regulatory requirements—typically 30 to 70% dose reduction over alternatives. This lower dose rate results in significant reductions in sludge volume; as much as 34% less sludge than alum and 50% less sludge than ferric coagulants. ClariPhos also helps improve sludge dewaterability, enabling up to 40% increase in attained solids.

Reports have estimated some wastewater plants may spend up to 40% of their operating budget on sludge management, so reduced sludge production and improved dewaterability can help significantly reduce sludge management costs.

Watch the video to see the faster settling and reduced sludge volume from ClariPhos compared to alum and ferric to remove an equivalent amount of phosphorus.

ClariPhos provides several other benefits that improve other aspects of plant operation and provide additional savings. These include:

Low acidity – reduced impact on pH

ClariPhos is 100 times less acidic than alum- or ferric-based coagulants and is typically dosed at a much lower rate. That means it is far less likely to lower pH of the wastewater system and require pH adjustment with alkaline chemicals.

Extensive operational and economic benefits

Wastewater treatment plants throughout the US and Canada have switched to ClariPhos or are evaluating its ability to comply with stringent phosphorus discharge limits. In addition to the advantages above, ClariPhos also provides many more operational benefits that include:

  • Low freeze temperature (-40°C); eliminating the need for heated storage and pipe heat tracing
  • Safer to handle than alum- or ferric-based coagulants
  • Inhibits struvite buildup
  • Repeatedly passes whole effluent toxicity testing at 100% effluent concentration
  • Doesn’t stain or discolour structures and equipment
  • Sludge is suitable for land application – rare earth elements have low toxicity and are not bioavailable to plants

Technical paper: The journey to select, design and install a BioCord condominium for bacteria in a far north lagoon

DATE POSTED: April 26, 2023

Presented by Tony Kobilnyk, Sales and Marketing Executive, at the 2023 WEAO Technical Symposium

In the cold and snowy terrain of Canada’s far north, traditional wastewater treatment lagoons face a daunting challenge: efficiently removing pollutants like ammonia and BOD from wastewater during the frigid winter months. The Gift Lake Metis Settlement in Northern Alberta is situated 400 km northwest of Edmonton, where temperatures can drop to -30°C. Traditional treatment lagoons suffer from decreased microbial activity in cold weather, leading to reduced effectiveness in removing ammonia and BOD from wastewater. To address this issue, Bishop BioCord™ Reactors offer optimal conditions for microbial growth and metabolism. The rope-type media and fine bubble aeration create a stable biofilm that insulates microorganisms, reducing the washout of bacteria and allowing for continuous treatment in winter conditions.

In the case study presented at the 2023 WEAO Technical Symposium, BioCord™ was evaluated against mechanical options, and was selected as the ideal upgrade option for Gift Lake Metis Settlement’s wastewater treatment lagoon. The BioCord™ system can be installed directly into the lagoon, eliminating the need for infrastructure additions and other costly components needed for post-lagoon systems like tanks, pipes, pumps, and blowers. The full-scale demonstration project, funded substantially by the Federation of Canadian Municipalities (FCM), Green Municipal Fund, involves the installation of nine reactors and baffle curtains directly into Cell 3 near the outlet, creating a compact, in situ treatment cell that will help the lagoons comply with WSER discharge limits consistently.

BioCord™ has demonstrated its ability to achieve and maintain cold-weather ammonia removal. BioCord™ Reactors can be shipped to site fully assembled and installed in just a few days, while the lagoon remains in operation.

The BioCord™ system offers several advantages, including low capital and operating costs, a semi-passive process that requires minimal operator oversight, and a modular design that allows for simple and affordable expansion. With the implementation of the BioCord™ technology, the Gift Lake Metis Settlement can upgrade their wastewater treatment system, improve ammonia and BOD removal in cold weather conditions, and keep costs affordable for the community. Bishop Water is grateful for the opportunity to present a case study of this technology during the 2023 WEAO Technical Symposium.

ClariPhos™: A less acidic coagulant that improves phosphorus removal and operator safety

DATE POSTED: March 31, 2023

Aluminum and iron-based coagulants are acidic, which means the more you add for phosphorus reduction, the more likely you are to lower the pH of the wastewater system. Consequently, wastewater plants must have pH adjustment measures in place to protect microbial populations from unfavourable conditions and to ensure the pH of treated effluent complies with discharge regulations. For operators, it means handling dangerous chemicals, more rigorous testing and monitoring, and unfortunately, increased exposure to safety risks when completing those tasks. 

ClariPhos™ Rare Earth Coagulant can dramatically reduce or even eliminate pH swings caused by chemical phosphorus precipitation and help improve operator safety at the same time. This unique, non-hazardous coagulant is up to 100x less acidic than Al- or Fe-based alternatives and can achieve better phosphorus removal with a far lower dose—anywhere from 30 to 70% lower dose, depending on the P removal requirement.  

By simply switching coagulants, operators can gain several health and safety benefits:

  • Lower ClariPhos dose rate enables operators to dramatically lower the volume of coagulant that is stored and handled in the plant.
  • Reduced impact on pH allows operators to decrease or eliminate the use, handling and storage of dangerous pH adjustment chemicals.
  • Non-hazardous, non-toxic rating reduces PPE requirements and the potential for operator injury. 
  • Low ClariPhos freeze temperature (-40°C) permits outdoor storage in totes or bulk tanks
  • Inhibits struvite buildup on pumps and staining of equipment, decreasing maintenance requirements and the associated risks of injury or exposure to pathogens 

ClariPhos also provides significant improvements in phosphorus removal and sludge management. Treatment plants using ClariPhos can: 

  • Achieve P level as low as 0.07 mg/L or better without the need for tertiary filtration 
  • Reduce sludge production by 30 to 50%
  • Improve sludge dewaterability by 40% 
  • Improve clarifier performance. ClariPhos precipitate settles up to two times faster than alternatives.

Switching to ClariPhos is easy. In most cases, the existing dosing equipment can be used for ClariPhos. So far, we’ve only encountered one issue—occasionally a smaller pump must be installed to ensure precise control of the low ClariPhos dose rate! 

Watch the video to see how ClariPhos performs against alum and ferric to remove an equivalent amount of phosphorus.

Shoreline erosion protection. How do Geotubes® stack up against other methods?


Does a massive Geotube® geotextile structure provide better shoreline protection than rip rap, armor stone or the other hard stabilization methods that are typically used to prevent erosion at waterfront properties?

There’s a lot of evidence to show that it can. Hundreds of kilometres of shoreline in more than 50 countries are using Geotube technology to protect against erosion caused by storms, waves, flood waters, ice and human activity. Many of these installations have been protecting shorelines for decades and face some of the toughest waves and weather on the planet.

Geotubes provide a resilient and cost-effective way to protect shorelines from erosion. The size, shape, materials and versatility of Geotube systems all contribute to their success in providing superior shoreline protection.

Here’s how:

1) Virtually immovable mass
Geotube containers can measure 100 feet (30.5 m) in length or more and when filled with sand can weigh in excess of 150 tons (136 tonnes). The Geotube and the consolidated sand inside of it, behave as a single, massive structure that is nearly impossible to be moved by waves or ice.

2) Durable, impact-resistant technology
Geotube containers are designed for long-lasting shoreline protection and are manufactured using high-strength polypropylene multifilament yarns that have been rigorously tested for fabric strength, seam strength, and resistance to UV exposure, souring and punctures. In extremely demanding applications, Geotube containers can be further protected with polyurea coatings or even conventional barriers such as riprap or armour stone.

3) Establish a softer, living shoreline
The tri-composite material traps soil and seeds, which helps to establish a covering layer of vegetation. Geotubes are often used in hybrid engineering approaches that combine soft or green nature-based methods with the structural properties of the Geotubes to create living shoreline stabilization systems.

4) Deflective elliptical shape
As ice advances towards the shoreline, the elliptical shape of the Geotube® containers can deflect it and prevent movement of the strucutre. Conventional barriers made of materials such as armour stone or timber face the ice head-on and can be dislodged or heaved up.

5) Simple installation
Geotube containers are filled in-place with a slurry mix of sand and water or locally dredged material. This simple process enables Geotube® containers to be installed much more quickly than conventional approaches such as armour stone or concrete. Once filled and installed, Geotube® containers with crimpled fibers enable soil to become entrapped and help establish vegetation that can further stabilize landscape as part of a “living shoreline” approach.  

A success story:
High water, waves and storms washed away much of the vegetation and sand dunes around a home on the shore of Lake Huron. See how our Geotube Shoreline Protection system provides a massive, virtually immovable structure that defends against erosion, enables beach restoration, and over time, can become a natural-looking living barrier.

What’s that smell? Diagnosing springtime lagoon odours.

DATE POSTED: February 28, 2023

Spring is almost here, which means lagoons will soon warm up and return to more efficient operation.

But as this happens, non-aerated lagoons, can experience benthal feedback—a process where the turbulence of the warming water stirs up the sludge blanket and releases hydrogen sulfide gas along with nutrients that have accumulated in the settled sludge.

The result can be wafting odours and complaints from the community. Unfortunately, the turbulence in the sludge can also cause elevated concentrations of TSS, BOD, phosphorus and ammonia in treated effluent. In severe cases, the concentrations can be higher in the effluent than the influent and cause non-compliance until the sludge settles again.

So, what can an operator do to prevent the situation from happening again?

An excessively thick sludge blanket can often be the cause of lagoon malodours.

Once the lagoon has undergone the smell test, an accurate diagnosis can be completed with a little time, observation and sampling.

The most obvious sign is sludge that is floating in the lagoon, or large deposits of sludge that rise close to the surface or above it. Samples of the lagoon effluent may exhibit a change in colour, reduced clarity and an abnormally high or non-compliant TSS level.

As sludge accumulates, storage capacity and retention time diminish, which can adversely impact nutrient removal. This can cause algae blooms and significant increases in TSS and BOD, potentially to
levels that are higher than that of the influent.

Short circuiting is another symptom of excess sludge that can also contribute to high effluent TSS. When this occurs, channels form in the sludge that cause wastewater to travel relatively quickly through the lagoon from the inlet to the outlet, rather than dispersing and remaining for the optimal residence time. The shallow depth of the lagoon may also cause poor settling and carry over of sludge into the effluent.

Sludge removal often solves the problem

Removing some, or all, of the sludge blanket can quickly restore lagoon capacity and eliminate performance issues. In some cases, the installation of baffles, aeration and/or fixed-film biological treatment can also provide a significant, cost-effective improvement to lagoon performance.

A sludge survey is an important first step to measure the thickness of the sludge blanket and how it’s distributed throughout the lagoon cell. Following that, Bishop Water can discuss important sludge management considerations and actions including:

• Current lagoon capacity vs. design capacity
• Depth and distribution of sludge
• Location and volume of recommended sludge removal
• Available budget and operational objectives
• Partial vs. total lagoon sludge cleanout

Depending on the results, urgency and budget availability, a total cleanout might be the right approach, or a partial cleanout to remove sludge only from areas of concern and defer the full cost to a future fiscal year.

Once a plan is ready, our team can begin mobilizing sludge removal equipment and the Bishop Solids Management Solution. This process provides a simple and cost-effective way to collect, dewater and contain sludge and achieves a high level of dry solids using only polymer conditioning, Geotube™ containers and gravity.

Compared to alternatives like centrifuges and belt presses, the Bishop Solids Management Solution is less complex, more energy efficient and can collect and dewater sludge at a significantly higher rate, which means projects can be completed faster and more affordably.

Read our case study to learn how a lagoon sludge cleanout enabled the O’Leary WWTF in PEI eliminate exceedances of TSS, BOD and coliform bacteria as well as blue-green algae blooms.

Is your lagoon suffering from washout?


Every wastewater plant can experience washout—a condition where high hydraulic loading causes microorganisms to be flushed out of a treatment cell at a faster rate than they can be replenished. It happens during periods of peak sanitary flow or during wet weather and its occurrence may be on the rise as we experience more frequent and extreme precipitation due to climate change. Inflow and infiltration can compound the problem adding more water to the sanitary system and further diluting the treatment process.

Diagnosing washout at your plant

Reducing retention times in treatment cells is the most common approach to enable lagoons to accommodate high hydraulic loading and avoid the need to bypass one or all of the treatment steps. But due to the faster flow, operators may see a decline in the treated effluent quality.

The telling sign of washout is that even after the influent flow returns to normal levels, the quality of treated effluent may continue to suffer days or even weeks after the event. This lag in performance indicates that a significant portion of the microbiological population has been lost to washout and the remainder is unable to provide adequate nutrient removal. The condition will continue until the microbiological population is re-established to the optimum level. 

In the warmer months, the microbial population can rebound fairly quickly. But since temperature plays a major role in the growth rate of nitrifying and heterotrophic bacteria, a washout in the fall or winter can have serious long-term consequences to lagoon performance. If temperatures drop after a washout event, the microbial population may not fully recover until the spring, which means the plant could have to operate at reduced capacity or face compliance issues through the cold-weather period. 

Build a better home for bacteria

BioCord™ Reactors are a simple, low-energy, fixed-film treatment technology that can help prevent the washout problem. BioCord is like a condominium for bacteria that adds a massive amount of surface area to a lagoon cell and provides the ideal environment for preferred, naturally occurring bacteria to thrive. Even though suspended bacteria may be lost to washout, BioCord retains its productive biofilm. The biofilm continues providing treatment, while also helping the lagoon return to optimum performance following the high-flow event.

BioCord boosts cold-weather performance too

The BioCord Reactor system is also designed to provide reliable removal of ammonia and BOD in cold weather. One way BioCord does that is by increasing the inventory of bacteria needed for wastewater treatment far beyond the capabilities of ordinary suspended sludge systems. More bacteria, means more nitrification and BOD removal.

BioCord Reactors can be installed directly into a treatment lagoon. They quickly establish a robust, stable biofilm that is resistant to washout and enhances plant performance in cold-weather conditions. 

Another way is that the BioCord biofilm develops in layers, which helps insulate inner microorganisms from cold water. This enables nitrifiers to maintain ammonia removal and respond to loading rates even when the wastewater temperature is as low as 0.5°C. BioCord biofilm has repeatedly demonstrated its ability to tolerate and thrive in cold conditions with observable changes in biofilm growth and greater ammonia removal rates as loading increases.

Case studies: Innovative, low-energy treatment to remove contaminants from process wastewater and ML/ARD

DATE POSTED: January 30, 2023

Presented by Tyler Anderson, Senior Project Manager, at 2022 Tailings and Mine Waste Conference

Mines, whether active or non-operational, can generate significant volumes of wastewater from mineral extraction / processing and from surface water that infiltrates the mine and comes into contact with contaminants. Waste streams of particular concern are high strength ammonia and metal leaching/acid rock drainage (ML/ARD), which must be collected and treated to prevent adverse impacts to surface and groundwater resources. Regulations limiting these contaminants continue to be strengthened, such as recent changes to Canada’s Metal and Diamond Mining Effluent Regulations (MDMER) that took effect in June 2021 and limit the monthly mean concentration of un-ionized ammonia in effluent discharge to 0.5 mg/L.

Tyler Anderson, our Senior Project Manager, presented a paper at the 2022 Tailings and Mine Waste Conference that introduced two of our simple, low-energy treatment technologies and provided case study examples where they have been cost-effectively installed and operated to address challenging waste streams from active and non-operating mines.

BioCord Reactors prove their ability to improve cold-weather ammonia removal

He first covered BioCord™ Reactors, a fixed-film (biofilm) technology that can be installed directly into wastewater treatment ponds to improve cold-weather ammonia removal and enable a mine site to meet more stringent discharge limits and increase the discharge rate from the plant. Then, a case study was presented to illustrate the results of a containerized pilot system that operated at a gold mine from August to December 2021. The system operated in two phases, receiving influent from two different cells of the wastewater system. This allowed the pilot system to demonstrate cold-weather nitrification at highly variable ammonia loading rates. The BioCord system successfully demonstrated its ability to remove up to 80% of the influent ammonia and achieve compliance with MDMER.

BioCord demonstrated its ability to achieve and maintain cold-weather ammonia removal. The first phase of a full-scale system is shown during installation.

Geotube dewatering systems simplify sludge management and enable permanent onsite storage

From there, Tyler presented two case studies about the permanent and long-term use of chemical conditioning and Geotube geotextile dewatering bags for solids capture and dewatering. This technology is particularly useful in situations where there is continuous and unpreventable drainage from resource extraction sites. These systems require little to no additional disturbance to existing sites and can accommodate a wide range of flowrates, covering seasonal fluctuations and thereby reducing the need for large pre- and post-treatment storage capacity. In some cases, the retained solids have proven to contain elevated concentrations of marketable compounds that can be considered a secondary benefit to utilizing these treatment systems.

One case study demonstrated the treatment of acid rock drainage using geotextile technology that has led to the recovery of valuable rare earth elements while preventing adverse impacts to downgradient waterbodies. A second similar case study described the collection and dewatering of sludge produced from the treatment of arsenic-laden groundwater that continually infiltrates a gold mine.

Robust cold-weather performance and lower cost make BioCord™ ideal choice for lagoon upgrade in Northern Alberta

DATE POSTED: November 30, 2022

BioCord lagoon upgrade for cold-weather biological treatment

Bishop BioCord™ Reactors have been chosen for a unique demonstration project to improve cold-weather biological treatment and effluent quality of the wastewater lagoons serving the Gift Lake Metis Settlement in Northern Alberta. The full-scale project will validate the ability of BioCord’s simple, low-energy treatment process to enhance the removal of ammonia and biochemical oxygen demand (BOD) in the lagoons during winter conditions and produce effluent that meets regulatory requirements for spring discharge to a nearby creek.

“As part of our assessment of the sewage treatment facility, we identified that the lagoons were not adequately treating the effluent as it progressed from one cell to another,” said Glen Pitt, P.L. (Eng), Principal of TeckEra Consulting. “Several upgrading options were evaluated. Bishop Water was engaged to provide technical guidance to improve the system performance without having to re-construct new lagoons or consider a mechanical treatment plant. The BioCord system was ultimately selected as the most cost effective and practical solution. Their personnel were fantastic to deal with and guided us through the initial testing and analysis phase to preparation of the funding application.”

The easy-to-operate, fixed-film reactors will be installed directly into a facultative lagoon cell while the plant remains in operation. BioCord’s in-situ design eliminates the need to expand the plant footprint or to add costly process infrastructure that post-lagoon or sidestream systems require, such as tanks, pipes, and blowers. Modular components will enable the BioCord system to be expanded as the community grows, which will help keep capital and operating costs aligned with near-term treatment needs and fiscal capacity.

BioCord provides a massive surface area on which biofilm thrives.
The BioCord media provides a massive surface area on which preferred, naturally occurring bacteria can attach and grow to produce a robust biofilm and improve year-round lagoon performance.

“BioCord Reactors are like a condominium for bacteria that supports a robust biofilm and increases the population of nitrifying bacteria far beyond what can be achieved in an ordinary suspended growth lagoon,” said Kevin Bossy, CEO of Bishop Water Technologies. “We are grateful for the opportunity to work with the Gift Lake Metis Settlement and TeckEra Consulting on this project and for funding support from the Federation of Canadian Municipalities to demonstrate BioCord’s cold weather performance and lagoon upgrade capabilities.” The Federation of Canadian Municipality Green Municipal Fund is providing a grant of up to $500,000 to cover up to 80% of eligible project costs.

BioCord Reactors will be installed directly into the lagoon cell, near the outlet, and will occupy less than two percent of the lagoon area.

The BioCord Reactors system will occupy a compact footprint of only 80 m2; just a fraction of the total lagoon area of nearly 6,000 m2. Despite the small size, the BioCord system is designed to handle the average flow of 190 m3/day and reduce BOD to less than 5 mg/L, ammonia to less than 1 mg/L and unionized ammonia to less than 0.1 mg/L.

A BioCord Reactors system can also achieve treatment targets using significantly less energy than alternatives, such as MBBR. This is possible because BioCord media is attached to a frame and does not require energy-intensive blowers to provide suspension and circulation of free-floating carrier media. Instead, each Reactor is equipped with an integrated fine-bubble aeration system powered by low-energy compressors. These components provide high oxygen transfer and can achieve the same or greater dissolved oxygen as other systems, while delivering approximately half the air.

“In coordination through our engineering consultant, Bishop Water has assisted our community on two major projects,” said Roger Higgins, Project Manager for Gift Lake Metis Settlement. “The first project was the installation of an OctoAir system and aeration lines. This significantly improved the quality of our drinking water by reducing the manganese levels in the raw water. Our second project is the design and construction of the BioCord system for our sanitary sewage treatment lagoon, which will be installed in early 2023. We are very pleased with the attention to detail and expertise from Bishop Water’s personnel.”

Once installation is completed, the BioCord system will have ample time to establish a robust biofilm and achieve steady-state nitrification for ammonia and BOD removal throughout the following winter.
