Product description Brand name and product description

The Biofil digester is a passive decentralized wastewater treatment system that uses aerobic decomposition and macro-organisms to break down waste. The typical digester accommodates 10 users and can be scaled to meet larger waste demands. The digester can also be modified to treat waste from existing septic tanks or treat sludge from other toilet systems. Efficiency of treatment and user capacity can be maximized by adding a “microflush” option which uses hand-washing greywater for flushing.
