Advanced Treatment Units - Presby Environmental EnviroFin

EnviroFin from Presby Environmental is a passive onsite wastewater treatment and dispersal system designed with a small footprint, to ship easily, and to exceed NSF/ANSI Standard 40 treatment. The effluent enters a fin distribution unit, or FDU, where it settles and breaks down suspended solids. Skimmer tabs located at the FDU’s perforations prevent grease and suspended solids from leaving the FDU. The FDU distributes the effluent into the treatment fins, which are filled with coarse green plastic fibers, creating a massive bacteria treatment area. Perforated air duct pipes run across the top of each treatment fin, providing oxygen to promote bacterial growth. 800-473-5298;
