PCDD/F EMISSION CONTROL BY INTERMEDIATE DUST REMOVAL AT MEDICAL WASTE INCINERATORS

A 1 tonne day-1 medical incinerator that meets the new national emission standards for PCDD/F of less than 0.1 ng TEQm-3 was installed in Eger, Hungary in January 1994. The unit is batch operated and is charged once or twice a day. It has an intermediate dust control filter between a pyrolysis chamber and an afterburner. Dry lime is inserted before this filter. Two polishing filters using zeolite and coke, respectively, follow a waste heat boiler. © 1996 ISWA Key Words—Dioxin control, PCDD/F, medical waste, hospital waste, batch in-cinerator, hot gas filter, Hungary. The implementation of regulations regarding the emissions of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs and PCDFs) from waste in-cineration has resulted in a need for control technologies. There are plenty of methods based on filter techniques. This paper gives information of another possible solution which has been used for preventing formation of PCDD/Fs and other toxic organic micropollutants (TOMPs). This study was conducted recently, so it is only possible to give a brief summary surveying the results
