Water borne wastes generated in the electroplating and metal finishing industry include: Rinse waters from plating, cleaning, and other surface finishing operations; Concentrated plating and finishing baths that are accidentally or intentionally discharged; Wastes from plant or equipment clean up; Sludges, filter cakes, etc.; Regenerants from ion exchange units; and Vent scrubber waters. Control measures discussed include in-plant control measures for waste reduction, as well as chemical, physical, and biological detoxification techniques for the various waters to be treated. The methods presented were developed for use by the large scale manufacturing operations and are now presented for the benefit of the small operator. Evaluation and cost estimation of these techniques as applied to smaller operations will be a major objective of investigations in subsequent phases of the program.
