HDPE Tank Biofilters

HDPE Tank Biofilters

High density polyethylene (HDPE) Tank treatment units from Waterloo Biofilter are constructed of a very high strength, durable, and seamlessly blow-moulded high-density polyethylene tank. HDPE Tanks are pre-plumbed at our factory, filled with the Waterloo Biofilter filtration medium, and shipped to site fully assembled. Treated effluent is pumped from the HDPE Tank to a small, shallow soil disposal system. HDPE Tanks operate in recirculation mode for increased nitrogen removal. These units are lightweight for ease of transport, and come pre-assembled for an easy, ‘dig-and-drop’ installation. The only moving parts are two high-quality, energy efficient 1/2 horsepower effluent pumps that operate intermittently throughout the day.
