Abstract

See full text

A system and method for treating high-strength organic liquid waste. Generally, the method includes feeding influent high-strength organic liquid waste including organic molecules to an anaerobic digester, converting at least a portion of the organic molecules in the liquid waste to acids using acid forming bacteria, converting at least a portion of the acids in the liquid waste to methane using methanogenic bacteria, separating the liquid waste after treatment with the methanogenic bacteria into alkaline sludge and effluent, and using the alkaline sludge to adjust the pH of the liquid waste in the anaerobic digester. In the case of acidic high-strength organic liquid wastes, a portion of the acids produced by the acid forming bacteria may be recirculated to the front of the anaerobic digester and combined with influent high-strength organic liquid waste.
