In Europe and the United States, both wet and dry (including semidry) scrubbing systems are being used for control of emissions from all types of waste incinerators. In terms of the effectiveness of controlling particulates and acid gases, both types of scrubbing systems are capable of meeting US Environmental Protection Agency and European Community limits. Two of the more difficult emissions requirements for an incinerator air-pollution-control system to meet are the metals and the dioxin/furan limits. The dioxin/furan emissions requirement is especially stringent, calling for levels below 1 ng (10{sup {minus}9}) per cubic meter toxic equivalency. The differences between wet and dry scrubbing systems are discussed in this paper, as well as the advantages and disadvantages of each in its application to the control of emissions from incinerators. Particular attention will be paid to control of metals and dioxin/furan emissions and to the sampling and analysis techniques used to measure these emissions. Toxic equivalency factors will be explained, and in particular, the international toxic equivalency factor proposed as the US and European standard will be discussed. This paper will also address some of the techniques being employed to minimize the emissions of toxic compounds and discuss the use of combined wet and dry scrubbing systems for increased assurance of compliance.
