For municipal wastewater sludge, SUEZ's municipal sludge solutions include advanced anaerobic digestion, upgraded digestion tanks, mixed digestion, and Class A municipal sludge.
Advanced anaerobic digestion adopts a hydraulic retention time design of 18 to 22 days to improve the conversion rate from sludge to energy. Upgrading the digestion tank can maximize the amount of biogas produced from the existing sludge flow, helping the factory move towards the goal of energy balance.
