Biperliminate to remediate legacy site in Glacier National Park

BI Pure Water has been awarded an Innovative Solutions Canada (ISC) contract for its Biperliminate™ Advanced Oxidation Process (AOP) to remediate groundwater toxins at Glacier National Park.

BI Pure Water is a BC-based designer and manufacturer of customized and modular water treatment solutions for potable and wastewater. This contract for $385,000 follows a thorough and exhaustive screening for the technology, the statement of work and the cost justifications.

At Roger’s Pass National Historic Site, the customized Biperliminate™ system will remediate poly-aromatic hydrocarbons (PAHs) such as Naphthalene (C10H8) and BTEX (Xylenes – C8H10), diesel fuel and metal contaminants to attain the most stringent fresh water specifications in Canada, i.e. the BC Freshwater Aquatic Life standard. The mobile trailer-mounted system has a capacity of 1-4 m3/hour. It is highly automated and remotely monitored by cell phone. The contaminants will be destroyed on site rather than being transported elsewhere for disposal.

The soil contamination at the site is a result of the transportation history of the area including the construction and operation of the railway through Rogers Pass in the late 1800s, followed by the construction of the Trans-Canada Highway in the 1960s, and the subsequent operation of a service station until 2009.

Biperliminate™ is a safe, low cost Advanced Oxidation Process (AOP). Difficult-to-destroy and persistent organic toxins in ground water are converted to safe end products such as vinegar and carbonate ions. Operating costs for the technology are typically $1 per cubic meter of wastewater or less.

Biperliminate™ technology has been effectively applied in the lab and at several pilot sites on other wastewaters including landfill leachates, mining waters including those contaminated with cyanide, municipal wastewater tertiary treatment, pharmaceutical, chemical and oil and gas wastewaters. There are many wastewater challenges in the world which Biperliminate™ can broadly target with this low cost on site Advanced Oxidation Process.

5 Ways To Optimize Your Sewage Treatment Plant

5 Ways To Optimize Your Sewage Treatment Plant

Some pointers to increase your plant’s capability without breaking the bank
If your sewage treatment plant (STP) has reached the limits of its hydraulic or operational capacity, or is not meeting new discharge requirements (BOD, TSS, Ammonia, TN, or TP), there are a few things you can do to avoid the capital dollars needed for a new system.

1) Convert the existing activated sludge process to IFAS (integrated fixed film activated sludge process) or MBR (membrane bioreactor)

Adding MBBR media to existing biological tanks is a “simple” method to increase the biological capacity and improve the effluent quality. Or, retrofitting the existing conventional biological system to the MBR process may be a feasible solution to meet stricter effluent quality requirements and capacity.

2) Reduce effluent TSS from 30 down to 10 mg/L with a polishing system

A wastewater filter, such as BI Pure Water’s low maintenance automatic inline filtration system, can be added as a tertiary treatment with a ballpark cost of approx $15,000 per 200 gpm. If you have a little more room in your budget and you’re looking for excellent effluent quality or even reusable water quality (TSS < 1 mg/L), ultrafiltration is an option. This should satisfy your E.coli requirement or total coliform to less than 200 — ie. final disinfection may not be needed.

3) Divert industrial stream wastewaters.

Industrial wastewaters can disrupt and/or add to load of municipal sewage plants. Pre-treatment (partial treatment) or full treatment at industrial sites either to discharge into municipal sewage system or discharge into the environment by itself or recycle the effluent can make economic sense rather than hauling away or paying full municipal disposal charges. Plus you earn full environmental credits for dealing with your own waste! A custom wastewater analysis is required for an industrial site. For the STP, a cost-efficient pre- or tertiary wastewater treatment system that targets industrial toxins can be designed with today’s advanced wastewater treatments that even addresses hormones, drugs, refinery/chemical wastes, household chemicals, pulp and paper wastes. All these hard to treat pollutants are making it difficult for the biology to do its job.

4) System analysis: evaluation from a knowledgeable STP engineer

An experienced sewage engineer will have years of experience analyzing different systems and employing the latest treatment technologies. He or she will look at performance issues, system optimization, and chemical and energy consumption. Treatment systems can benefit from some of the new technologies that improve performance or reduce consumables and energy. As the owner or manager of a sewage treatment plant, your mandate is to optimize the treatment process and keep costs low. By going directly to a sewage system provider such as BI Pure Water that has wastewater treatment engineers on staff, you can save on engineering fees.

Accu-Tab for BIPW-Chlorinators is the only NSF 61 rated

Written by Marketing on . Posted in water treatment tips

Ensure you use Accu-Tabs to retain drinking water rating NSF61

AccuTabs certified NSF61Copycat Accu-Tabs are widely available; however chlorine feeders not using the branded product, including those customers with BIPW chlorinators, are not compliant with NSF 61 (drinking water standard).

According to NSF International, “Chlorine feeders are required to be used with and only with the manufacturer’s recommended use chemicals and these chemicals need to comply with the requirements of NSF/ANSI Standard 60.”

Accu-Tabs are a specific approved chemical component (68% calcium hypochlorite) that are specifically designed to erode at the appropriate rate.

The same goes for Accu-Tabs in pools. “Chlorine feeders that are certified to NSF/ANSI Standard 50 for use in pool, spa, and recreational water facilities are evaluated and certified for use with-and only with- the manufacturer’s recommended use chemicals,” according to NSF International.

Design-build package plant versus design-bid-build for First Nations

design-build advantagesThe Assembly of First Nations provided a powerful forum Feb 6-8, 2018 for a discussion on how to resolve First Nations water issues. During one afternoon, Scott Foster of BI Pure Water proposed Design-Build of treatment plants rather than Design-Bid-Build. A productive discussion ensued. We welcome your comments.

The issues:

Potable Water Health Problems

  • Many treatment plants are outdated or are undersized for growing communities.
  • Hundreds of “Boil Water Notices” exist for the main treatment plants across Canada.
  • Boiling doesn’t remove dangerous items like Arsenic or Manganese.
  • Residents need to resort to expensive and inconvenient bottled water.
  • Small groups of residences are beyond the distribution pipeline and not served.


  • Many of the treatment plants are located in remote areas so it is difficult to bring in supplies.
  • Often the community wasn’t consulted as to their primary water needs.
  • Some plants are difficult to operate and cause water outages or downtime.
  • Operator training and plant capital maintenance is often difficult to fund.
  • Many plants don’t have remote monitoring.
  • Very high cost of Design-Bid-Build plants.

New solutions are being developed:

  • Community Circle approach to gathering information and defining the needs of the residents.
  • Cost and time savings by delivering standardized treatment systems.
  • Modern communications, remote monitoring, and new technologies make it a little easier to maintain the system
  • Design-Build approach to supplying the treatment systems vs the old Design-Tender-Build method.

Design-Build Your Water Treatment System:

  • Meet with Elders and Council to assess community needs
  • Determine Operator needs
  • Review potable water regulations
  • Engineering process, meet all requirements, consider also “Design for Resilience”
  • Specify low maintenance system
  • Review with regulators
  • Program the system
  • Remote monitoring
  • Manufacture & test in plant
  • Inspection by owner and approval
  • Deliver to site
  • Commissioning, training, servicing
  • Design-builders in general have ability to service plants over long term and provide correct replacement parts
  • Design-builders can remotely support the operator with proper electronics.

Potable Water Requirements

Water suppliers are required to provide long term plans to reach the goals of:

  • 99.99% inactivation of viruses – “Bugs”
  • 99.9% removal or inactivation of Giardia Lamlia and Cryptosporidium – “Cysts”
  • Two treatment processes for all surface drinking water systems
  • 0.1 NTU Turbidity – “Water clarity”
  • Zero tolerance for total and fecal coliforms and E.Coli – “Worst bugs”

Does your water treatment system include organics removal to prevent chlorine byproducts?

Does your water treatment system include organics removal to prevent chlorine byproducts?

“We’re not seeing all engineering consultants providing new water system designs that address organics before disinfection systems, such as chlorination and UV, and I’m concerned about it,” says BI Pure Water’s Engineering Manager, Paul Anderson. “Frankly I wouldn’t drink the water if the THMs were over 25 ppb.”

chlorine byproducts formationChlorine byproducts such as THMs (all are called TTHMs), and haloacetic acids (HAA) are formed when chlorine interacts with naturally occuring organic matter in the source water. “There are serious negative health effects with long term exposure to these disinfection byproducts. The City of Vancouver is concerned enough to lower their THMs to 25 ppb. The EPA has lowered the Stage 1 Disinfectants and Disinfection Byproducts Rule to regulate total trihalomethanes (TTHM) at a maximum allowable annual average level of 80 parts per billion (µg/L) from 100 ppb.”

“The water quality of communities, which they should have published on their websites, should indicate THMs well below the max, and we’re not seeing that. The public must demand good water treatment.”

Some UVs may even increase the problem of disinfection byproducts by breaking organic material into smaller particles with more surface area that results in even higher THMs.

BI Pure water’s senior engineer, George Thorpe, who watches the EPA studies, notes that research underway is showing that there are many more disinfection byproducts than are currently known, and long term studies on human health are underway.

MBRs allow water reuse of sewage treatment

MBRs allow water reuse of sewage treatment

Advanced Waste Systems brochure Advanced Wastewater Treatments explained
Brochure download (4pps,Zip PDF)

Subdivisions continue to multiply. Developers routinely contact us for proposals for communities that are ‘outside the water treatment grid’ and are sourcing water and wastewater treatment systems. Water can be expensive to bring to these communities and they are keen to reuse water wherever possible.

With a membrane bioreactor communities are able to both treat sewage and recover bacteria and pathogen free water for their fire stations, as well as irrigation. This can mean big environmental and promotional benefits for developers, not to mention cost savings!

At BI Pure Water we would like to see communities using MBR because it can be a completely closed loop system. Dewatered sludge can be spread on fields, recovering nitrogen and phosphorus, or mixed into compost. The MBR requires a little more skilled maintenance than a MBBR or SBR system because it requires – two or three times a year typically – a chemical clean of membranes. Also the membranes need to be monitored for breaks or fouling, though these symptoms would be monitored through the computer control system.

A budgetary price proposed for this typical subdivision is under $200,000 for the first 100 dwellings. MBR is modular so in Phase II and III of the development another MBR would be added later to defer capital costs.

MBRs are built and tested complete inside a container or steel framed building. This can save on construction costs and are hassle-free by being built and tested in the factory and shipped complete and ready for implementation in the community. The plants are by nature steel frame structures that are resistant to extreme weather events, as well as mold, wildlife and rodents.
