BQE Water Successfully Completes Pilot for Joint Sulphate and Selenium Removal from BC Mine Water

VANCOUVER, BC – BQE Water Inc. (TSX-V: BQE), a leader in the management of mine wastewaters and metallurgical bleed streams, has successfully completed a pilot demonstration for a project in BC requiring the simultaneous removal of sulphate and selenium from mine water to comply with provincial water quality regulations. In the pilot, sulphate was reduced to as low as 30 mg/L and selenium to less than 1 ug/L, exceeding current provincial limits of 120 to 400 mg/L and 2 ug/L respectively.

The project required BQE Water to complete an assessment of possible treatment options that would meet water quality targets while minimizing waste by-product generation and disposal. The outcome of the assessment was a treatment approach that combined nanofiltration with the selenium electro-reduction circuit that forms the Company’s Selen-IX™ process technology.

David Kratochvil, President & CEO of BQE Water, commented, “The ability to manage sulphate and selenium simultaneously is of interest to a number of mining projects in BC and this pilot confirms to both industry and regulatory agencies that an effective treatment process is available. The success of this pilot builds on BQE Water’s prior experience with sulphate removal using nanofiltration and selenium removal by electro-reduction to create an important new tool in our technological toolbox.”

Adds Farzad Mohamm, Director of Technology for BQE Water, “The significance of this pilot project is threefold: it provides the mining industry with a single treatment process to meet sulphate and selenium regulations simultaneously, it broadens the applicability of BQE Water’s electro-reduction know-how and its application to other target constituents of concern, and it enables the application of nanofiltration in mining without generating a waste liquid brine.”

In addition to confirming the ability of the treatment process to comply with regulatory limits, the pilot also demonstrated the ability of the process to adapt to fluctuations in water quality and generate stable non-hazardous solids for convenient disposal at site.

About Sulphate
When sulphide minerals are exposed to oxygen, sulphate is released into mine water in quantities that greatly exceed typical levels found in surface or ground water. Although not usually toxic, sulphate can have negative impacts on downstream environments and several jurisdictions around the world have started to regulate sulphate.

About Selenium
Selenium is a naturally occurring element essential to all life forms in trace amounts. It is transferred into water through the weathering of plant life, soils and bedrocks. Selenium is also released into water as a by-product of mining activities. When selenium is present in water at higher concentrations, it is harmful to most fish and other aquatic life. As a result, selenium management has been identified as an important environmental issue by regulators and the industry in North America.
