Description:
The Site 1 plant treats 36MGD of wastewater and the blended primary/secondary sludge is dewatered to approximately 16 to 2O percent solids. ludge is incinerated by a six-hearth unit at approximately 6.0 wet tons per hour. missions are controlled by a three tray impingement scrubber using either a mixture of primary and secondary effluent or just secondary effluent as the scrubber liquor. ests were conducted to determine particulate, metals, and organic parameters of sludge, inlet scrubber water, and scrubber exhaust gases. ead was the most prominent metal emission while beryllium was below the detection limit in the flue gas. hromium had the highest concentrations in the sludge and arsenic was below the detection limit. ll target volatile organics were detected in the flue gas samples, while only 2 of the 14 species were detected in sludge feed and scrubber water samples. he most concentrated species found in the flue gas were benzene, acrylonitrile and tetrachloroethane. nly four of the target semi-volatile organics were found in the flue gas samples while none were found in sludge feed and scrubber water samples. is(2-ethylhexyl)phthalate and three dichlorobenzenes were the compounds detected.
