Digest the organic matter
|
Detailed explanation-1: -Anaerobic digestion is the biological degradation of organic matter in the absence of free oxygen. During this process, much of the organic matter is converted to biogas (methane, carbon dioxide and water) (CPHEEO 2012).
Detailed explanation-2: -Solution : Anaerobic bacteria (Methano bacterium/Methanogenic bacteria).
Detailed explanation-3: -Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process. AD stabilises the sludge biologically in the absence of air. In doing so, it reduces the amount of volatile solids by their conversion to a biogas (methane CH4, carbon dioxide CO2 and water H2O).
Detailed explanation-4: -In anaerobic sludge digester the anaerobic bacteria the methanogen digest the flocks of bacteria and fungi in activated sludge and produce methane along with H2O and CO2 i.e. biogas which is a source of energy as it is inflammable.
