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