Two-Phase Anaerobic Digestion System
This unique two-phase anaerobic digestion system produces Class A Biosolids, which can be land - applied without restrictions in accordance with the EPA’s 40 CFR Part 503 regulations. Our innovative process separates the acid - and methane - forming digestion phases (acidogenesis and methanogenesis), increasing the efficiency of both and, combined with the high temperature, destroys the pathogens to below detectable limits. A two - year pilot study confirmed the effectiveness of the 2PAD System to meet EPA requirements for Class A Biosolids. In fact, the 2PAD System has been granted “PFRP Conditional National Equivalency” by the Environmental Protection Agency, as recommended by the Pathogen Equivalency Committee.
