A pilot-scale electrostatic precipitator (ESP) was evaluated for its removal performance of 23 metals and for sulfur-containing particles when fitted to a multiple hearth incinerator burning sewage sludge. The small-scale ESP was installed to take a slipstream of about 3% of the total incinerator emissions. Particle size fractions were collected from the gas streams entering and leaving the ESP. Each particle was evaluated for overall removal efficiency, size-fraction removal efficiency, and selective removal of specific metals. Total concentrations of each element in the controlled emission stream was determined as well as the proportionate concentration of species in the solid and volatile states. Concentrations of each metal in the emission stream were compared with the concentration in the sludge residue. To obtain comparisons of ESP performance with a more typical emission-control device, the performance of the incinerator's full-scale wet scrubber was also evaluated.
