| Abstract |
The report describes the waste applicability and performance characteristics of hazardous waste pretreatment processes. Pretreatment processes are those unit operations which must often be carried out on hazardous wastes to make them amenable to subsequent materials or energy recovery steps, to chemical or biological detoxification, thermal destruction or safe land disposal. The pretreatment processes covered are primarily phase separation (floatation, filtration, distillation, etc.) and component separation (adsorption, stripping, solvent extraction, etc.) techniques. Methods for selecting the appropriate pretreatment process are provided as a function of waste characteristics, treatment objective, technical adequacy, performance, and cost and energy considerations. Detailed summaries are provided for the various techniques along with relevant performance data. |
