ABSTRACT

Separation processes are widely used both in the minimization of hazardous wastes and in the treatment of hazardous wastes before disposal. The treatment before disposal is done to recover valuable components and at the same time remove hazardous materials from the disposed stream. In addition to separation processes, many types of conversion processes are also used to treat waste streams before or during disposal. Some examples are incineration, wet oxidation, pyrolysis, hydrolysis, dehalogenation, or photolysis. The purpose of these conversion processes is to destroy hazardous components in a waste either prior to or during disposal. Freeman (1988) gives a good discussion of these conversion processes in his Standard Handbook of Hazardous Waste Treatment and Disposal.
