Description:
Emissions of metals and organics from a series of four wastewater sludge incinerators were determined. hree multiple hearth units and one fluidized bed combustor were tested. missions were controlled with a combination of venturi and/or tray impingement scrubbers. ne site incorporated an afterburner as well. lue gas testing was conducted at the inlet and outlet to the air pollution control devices at two of the plants. eed sludge was also extensively tested for moisture, metals, and organics, as well as overall feed rate and heating value. esting operating conditions were categorized as short-term versus long term (transients, start-up, interruptions, etc.) he metals found in greatest concentrations in the sludge were lead, chromium, and nickel; and the highest metal emission rates were lead and cadmium. rganics were tested for in terms of volatile species (B.P. 30 degrees C -100 degrees C) and semi-volatile species. or the volatile species, toluene had the highest concentrations in the sludge and acrylonitrile, benzene, toluene, chloroform, and vinyl chloride had the highest emission rates. ew of the target semi-volatile compounds were detected in either the sludge feed or at the stack.
