:: Technology 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. |
