Emissions of metals and organics from municipal waste-water sludge incinerators. Volume 5. Site 3 final emission-test report. Final report, 1987-90
The Site 3 plant treats 2.5 MGD (designed for 7.5 MGD) of municipal wastewater. The blended primary/secondary sludge is dewatered using 2 belt filter presses to about 22 to 24 percent solids. Sludge is fed to a fluidized bed incinerator which is designed to burn 2.75 dry tons per hour. Emissions are controlled by a variable throat venturi followed by a three-tray impingement scrubber. The scrubber uses tertiary-treated nonchlorinated plant effluent. Tests were conducted to determine particulate, metals, and organic emissions. In addition to sampling flue gases at the scrubber outlet stack, scrubber influent water and sludge feed samples were also taken. Nickel was the most prominent metal emission and also had the highest concentration in the sludge feed. Ten of the fourteen target volatile organic compounds were detected in the flue gas in at least one of the VOST runs. The most concentrated species detected were chloroform and benzene in the stack gas; toluene, tetrachloroethene and ethylbenzene in the sludge feed; and chloroform and methylene chloride in the process water. Bis(2-ethylhexyl)phthalate was detected in the flue gas, sludge feed, and process water semi-volatile samples. No other semi-volatile compound was detected in the flue gas samples.
