Emissions of metals, chromium and nickel species, and organics from municipal waste-water-sludge incinerators. Volume 6. Site 8 emission-test report. Final report, 1989-91
The Site 8 facility is a 24.1 million gallons per day (MGD) secondary biological treatment plant with a 0.1 MGD septage handling facility. The wastewater influent comes from predominantly (90 percent) domestic sour ces. The treatment facility serves a population of approximately 175,000. All 22 tons per day of sludge solids are dewatered by two belt presses to a concentration of 22 to 25 percent solids. Approximately 15 to 17 tons of solids are dewatered by one press and fed to the fluidized bed incinerator. The air pollution control system associated with the incinerator consists of a water injection venturi, and an impingement tray scrubber. A pilot-scale wet eletrostatic precipitator had been installed and was tested. The ratio of hexavalent chromium to total chromium in the emissions was very low (despite relatively high total chromium levels), probably due to the short sludge retention time in the fluidized bed incinerator and the absence of alkaline material in the sludege. The ratio of nickel subsulfide to total nickel in the emissions was extremely low, with the nickel sulfide/subsulfide species measured at the inlet and midpoint being less than the detection limit. Compared to Site 3, a fluidized bed incinerator where the only semi-volatile organic compound detected was bis(2-ethylhexyl)phthalate, several additional semivolatiles were found in the emissions at Site 8. These were 1,2-dichlorobenzene, 1,4-dichlorobenzene, benzyl alcohol, benzoic acid, and naphthalene. The volatile organic compound emission results for Site 8 were consistent with the results for Site 3 (an other fluidized-bed incinerator). Carbon tetrachloride and chlorobenzene, reported in the emissions at Site 3, were not found in the emissions from Site 8.
