BI Pure Water Receives IRAP Grant
for the low cost remediation of
Refractory Organic Contaminants

For immediate release – June 5, 2017
BI Pure Water, Inc. has been approved for an IRAP grant (National Research Council Canada’s Industrial Research Assistance Program) to pilot its low cost remediation solution for Refractory (difficult-to-oxidize) Organic Contaminants. BI Pure Water’s in-house master chemist Ian Wylie has been personally working on the chemical problem for a decade and he believes he’s found a low cost solution.

“There are so many unaddressed industrial chemicals in our environment, I find this a very exciting and promising market,” says Ian Wylie, R&D Project Manager. “This process should be able to treat refractory wastewaters at an operating cost 5-20 times lower than existing oxidation processes and other environmentally unsound methods, such as incineration.”

BI Pure Water’s Advanced Oxidation Process (AOP) in combination with biological treatment will greatly expand the range of wastewaters treatable by biology. AOP used in combination with MBR/MBBR or biogas generation is cheaper, more effective and ‘much greener’ than competing processes.

The process is particularly useful for refractory wastes with aromatic functionality and many other difficult to treat organic chemical contaminants, such as: phenol from refineries and chemical synthesis, polychlorinated biphenyls, creosotes, naphthenic acids from oil/gas extraction, drugs and synthetic hormones from the pharmaceutical industry and a wide range of difficult to treat industrial wastewaters.

BI Pure has found its first pilot project with leachate from a Canadian landfill. We are seeking more partnerships with potential customers that have “challenging waters” that need a practical way to reduce harmful waste. To pilot and demonstrate the technology the project is seeking partners that spend more than $ per m3 to dispose of their difficult waste.

MBRs allow water reuse of sewage treatment

Subdivisions continue to multiply in Calgary. Developers routinely contact us for proposals for communities that are ‘outside the water treatment grid’ and are sourcing water and wastewater treatment systems. Water is a scarce resource in 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.
