How it Works

The Waterloo Biofilter ® system is a single-pass aerobic filter designed for the biological treatment of wastewater. The patented process utilizes an absorbent synthetic filter medium designed to optimize the biological degradation of wastewater. Natural microbial action in the filter medium is enhanced by its high porosity, large available surface area, excellent air flow characteristics and ease of microbial attachment. The filter medium has optimized flow characteristics which allow for high loading rate and compact size. Allowable loading rates are typically 10 times greater than sand filters or soils. The Biofilter typically removes 90-95% BOD, 85-98% TSS, 20-50% TN and 90-99% coliform bacteria.

  The Waterloo Biofilter ® synthetic filter medium allows separate flow paths for air and wastewater. The result is effective treatment and high loading rates.
  Traditional trickling filters (sand) rely on solid particles as a filter medium. This limits the airflow and wastewater flow to the biomat and the filters' effectiveness.
