Compact solution ideal for discharge into the environment

The Waterloo Biofilter easily adapts to even the most difficult sites, whether your lot is small, or the bedrock, water table or impervious ground layer are close to the surface, or your installation is located in an environmentally-sensitive area. 


This technology is well adapted to the Canadian climate.  It maintains a high yield even in cold weather, it eliminates a significant part of the nitrogen present in wastewater, and it does not take a lot of space on the lot.

How does it work?

The key to the Waterloo Biofilter is its patented filter medium. Wastewater is distributed evenly over the filter where it is absorbed and held just long enough to allow an efficient reduction of pollutants.


As the wastewater slowly trickles down, naturally occurring microorganisms develop on the medium, where they degrade and decompose solid and organic matter to eliminate some of the fecal coliforms to produce a clear, odorless output.


Finally, the biofilter output is sent to a UV reactor to finalize the treatment by destroying the rest of the fecal coliforms to produce a quality tertiary effluent that can be subject to different types of discharges in accordance with Québec regulations.
