SYSTEM AND METHODS FOR IMPROVED ANAEROBIC DIGESTION

Abstract:

The present disclosure relates generally to systems and methods for improving performance of anaerobic digestion by post-anaerobic digestion processing. The post-anaerobic digestion processing includes introducing a digestate to post-anaerobic digestion microorganisms downstream of an anaerobic digestion process, wherein the digestate is a product of anaerobic digestion and the post-anaerobic digestion microorganisms hydrolyze and ferment the digestate to produce hydrolysis and fermentation products. In some instances, the systems and methods further include introducing the hydrolysis and fermentation products to anaerobic digestion microorganisms, wherein the anaerobic digestion microorganisms convert the hydrolysis and fermentation products into biogas.
