The Site 2 plant treats 38 MGD of municipal and to a lesser degree industrial wastewater. The blended primary/secondary sludge (approx 65-86% primary) is dewatered using centrifugation to about 18 to 25 percent solids. Sludge is fed to an eight-hearth incinerator at approximately 7.0 wet tons per hour. Emissions are controlled by a variable-throat venturi/impingement scrubber which uses secondary effluent as the scrubber liquor. Tests were conducted to determine particulate, metals, and organic emissions. In addition to sampling flue gases at the scrubber inlet and outlet, sludge feed, incinerator ash and scrubber inlet and outlet water was also sampled. Lead had the highest scrubber inlet flue gas concentrations during both short-term and long-term tests. Emission rates of cadmium, nickel, chromium and arsenic were also detected. Average scrubber removal efficiencies exceeded 53 percent for all metals. All of the target volatile organics except 1,2 dichloroethane were detected in the flue gas samples. The species detected in the highest concentrations were acrylonitrile, toluene, benzene, and vinylchloride. Up to seven target semi-volatile compounds were detected in the flue gas samples with phenol being the most prominent.
