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.
