Waterloo Biofilter designs and manufactures patented, free-draining, absorbent trickling filters ideal for residential, communal and commercial sites. Our systems are installed across Canada, the US and Korea, treating sewage on-site from numerous applications. Third-party testing over 14 years has shown consistent removal rates of 90-95% BOD, 90-97% TSS, 99% fecal coliform and up to 60% TN.

The compact Waterloo® system is discreet, modular, customizable, self-contained and very robust. High strength wastewaters, seasonal operation and weekend surge flows are easily accommodated. The lack of generation of aerobic sludge, small space, and low maintenance and energy requirements are distinct advantages over other aerobic systems. Our attractive packaged treatment plants ship easily and arrive pre-assembled and ready to plug-in. Options include water re-use for irrigation, above or below ground configurations, sub-surface or surface disposal, and remote monitoring.
