Abstract Full scale combined sludge generation from a treatment sequence consisting of lime clarification, nitrification, and denitrification was studied. Pilot scale studies were conducted to wet-classify and dewater the combined sludges by means of two-stage solid bowl centrifugation. Anaerobic digestion of first stage centrate was also studied on a pilot scale. (Modified author abstract)
