Capital and annual costs were calculated for applying six different air pollution control systems to municipal sewage sludge incinerators that were using multiple-hearth furnaces. The systems involved three principal types of air pollution equipment-wet scrubbers, fabric filters, and electrostatic precipitators-applied to three different plant sizes (plants incinerating 36, 72, and 300 tons of dry sludge per day in one, two, and eight multiple-hearth furnaces, respectively). Technical feasibility studies indicated that all three types of controls could achieve a total particulate removal efficiency of 99 percent.
