Detailed explanation-1: -Anaerobic digestion, widely used as a source of renewable energy is the process that takes place in an anaerobic sludge digester. The process produces biogas, consisting of methane, carbon dioxide and traces of hydrogen sulfide and ammonia.
Detailed explanation-2: -Anaerobic Digester Outputs Anaerobic digestion produces two valuable outputs: biogas and digestate.
Detailed explanation-3: -High sulfur content in excess sludge impacts the production of biomethane during anaerobic digestion, meanwhile leads to hydrogen sulfide (H2S) formation in biogas.
Detailed explanation-4: -In the anaerobic digesters the organic matters are degraded by anaerobic bacteria. In the absence of oxygen the sulfate is converted to hydrogen sulfide (H2S) which is a gas. Thus, after the anaerobic digestion process, the sulfur compounds present in the inlet stream leave the reactor through the biogas as H2S.
