Anaerobic digestion is a bacterial process that is carried out in the absence of oxygen. The process can either be thermophilic digestion in which sludge is fermented in tanks at a temperature of 55 °C or mesophilic at a temperature of around 36 °C.Though allowing shorter retention time (and thus smaller tanks) thermophilic digestion is more expensive in terms of energy consumption for
