Emissions of metals, chromium and nickel species, and organics from municipal waste-water-sludge incinerators. Volume 8. Site 9 emission-test report. Final report, 1989-91
Site 9 is a secondary plant designed for 15 million gallons per day (MGD) of wastewater flow. The sludge incinerator at Site 9 is a seven (7) hearth, multiple hearth furnace (MHF) built by Nichols Engineering in 1974 controlled by an adjustable throat venturi, with a nominal pressure drop of 20 in. w.c.. After leaving the venturi, the gases pass upward through a three (3) plate tray scrubber with a Chevron mist eliminator. A 10 ft. x 10 ft., upflow, wet electrostatic precipitator, manufacturer by Beltran Associates, Inc., was installed during the first week of testing. The ratio of nickel subsulfide to total nickel in the emission at Site 9 is extremely low, with the sulfidic nickel species being measured at less than detection limit (about 1 to 2 percent of the total nickel). The ratio of hexavalent chromium to total chromium in the emissions at Site 9 was significantly higher that had been anticipated. Site 9 had only two semivolatile organic compounds detected under normal and improved combustion conditions benzyl alcohol and benzoic acid. Several additional compounds were found in the emissions for the normal or improved combustion conditions at Site 9; these compounds were 1,4-dichlorobenzene, 1,2-dichlorobenzene, 2-nitrophenol, 1,2,4-Trichlorobenzene, naphthalene, 2-methylnaphthalene, dibenzofuran, phenanthrene, bis(2-ethylhexyl)phthalate, phenol, 4-methylphenol, and 4-nitrophenol. The volatile organic compounds detected in the Site 9 multiple hearth incinerator emissions were similar to the compounds reported for Sites 1, 2, and 4 (other multiple hearth incinerator tested). Carbon tetrachloride and carbon tetrachloride, reported in the emissions at the other three sites, were not found in the emissions from Site 9.
