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: -Digested sludge contains an association of anaerobic fermentation and methanogenic bacteria producing carbon dioxide and methane.
Detailed explanation-4: -Sludge gas production During this time fermentation of the sludge takes place due to the action of naturally occurring methanogenic bacteria, which results in the formation of a gas rich in CH 4 and also containing carbon dioxide (CO2), nitrogen (Nz) and a trace of hydrogen sulphide (H2S).
