Laboratory and pilot scale studies were carried out on the feasibility of applying the PACT system (involving addition of powdered activated carbon to the aeration tanks in the activated sludge process, and wet-air oxidation of the sludge to recover carbon) to the treatment of wastewaters from the Lurgi/Mobil M process, which produces synthesis gas, and a coal liquefaction process. The PACT system provided continuous, reliable treatment. A 2-stage process gave the best overall removal of COD and DOC. Both single and 2-stage systems achieved consistent nitrification of the wastewaters, producing effluents containing < 1 mg NH/sub 3//l.
