A study was made at pilot scale of a variety of processes for dewatering and stabilization of waste activated sludge from a pure oxygen activated sludge system. Processes evaluated included gravity thickening, dissolved air flotation thickening, basket centrifugation, scroll centrifugation, aerobic digestion, and anaerobic digestion (mesophillic and thermophillic). In addition combinations of processes were evaluated including: scroll centrifugation after anaerobic digestion, basket centrifugation after anaerobic digestion, centrifugation of mixtures of anaerobically digested primary sludge and anaerobically digested waste activated sludge, centrifugation after thermal conditioning and composting after digestion and centrifugal dewatering. Data are presented on all of the processes above and optimum economic combinations are identified.
