Biochar h2s anaerobic digester
WebJun 27, 2024 · 1. Introduction. Anaerobic digestion (AD) is an important biotechnological process which allows the treatment of organic wastes and production of biomethane. Mechanistically, during AD, the organic matter undergoes fermentation degradation using protons and HCO 3- as electron acceptors due to the absence of oxygen. WebThe effect of biochar addition on the anaerobic digestion (AD) of food waste was evaluated. From the five biochars tested, Fe, Co, Ni, and Mn were leached in very small quantities (less than 10 mg/kg), while a high amount of K (1510 and 1969 mg/kg) was leached from treated waste wood and willow tree pyrochar, respectively. AD batch …
