:: Technology : Advantages 

  Waterloo Biofilter ® is robust, compact, efficient and cost-effective.

  The compact nature of the Waterloo Biofilter ® reduces the impact of the septic system on the surrounding environment and preserves the natural landscape, waterfront, and minimizes tree-cutting.

  Dense clay soils, bedrock areas, high water tables, and space limitations/lot size are domestic wastewater problems that the Waterloo Biofilter ® can easily solve.

  The quality of the treated effluent is high enough that large and space-consuming traditional tile beds are not needed. Discharge of treated effluent typically can be discharged into a short shallow trench in sand or clay.

  Easy to operate, low maintenance and primarily passive.

  Suitable for cold weather (-40°C) and seasonal operation.

  The system can be easily scaled for different sized applications (1,500 L/day to >100,000 L/day) by increasing medium depth and by adding Biofilter modules.

  The system is very effective for communal applications such as campgrounds, resorts, and rural sub-divisions.

  Both underground and above ground configurations are available.

  The system can also effectively treat industrial and municipal wastewater including but not limited to:

• on-site treatment and disposal of landfill leachate
• sewage lagoon effluent polishing
• nitrification and polishing of municipal wastewater
• food processing wastewater
• reducing BOD5 levels in industrial sewer discharges

  The Waterloo Biofilter ® is a proven technology that is becoming accepted by regulators and health departments in Canada and the United States. Years of detailed monitoring of field units by independent agents have proven the system to be effective and reliable.
