Anaerobic Waste Treatment Definition: Analobic treatment is a biological process carried out in the absence of O,for the stabilization of organic materials by conversion to CH4 and inorganic end-products such as CO2 and NH3. Anaerobic microorganisms Organic materials Nutrients CH CO2 +NH3 Biomass Anaerobic processes Anaerobic fermentation Anaerobic respiration
