SUMMARY REPORT: CONTROL AND TREATMENT TECHNOLOGY FOR THE METAL FINISHING INDUSTRY: IN -PLANT CHANGES. U.S. Environmental Protection Agency, Washington, D.C., EPA/625/8-82/008.
Description:
This 30 - page Technology Transfer Report ummarizes how he metal finishing industry in the United States is subject to a variety of changing business conditions. wo of the most significant factors are the increasing costs of materials, such as plating chemicals and process water, and the environmental considerations, which include the need to control the discharge of effluent waste streams and the disposal of hazardous wastes. he survival of many metal finishing companies will depend on how effectively they deal with the impact of these changes and requirements. Because of rising prices and changing regulations, it is necessary to reevaluate water pollution control techniques and costs nd to examine methods for improving raw material yields. n many cases, changing the manufacturing process can significantly alter chemical losses and water flow rates. hese in-plant changes usually involve techniques for reducing both the drag-out removed from process solutions and the amount of water used in the rinsing process. The overall effect is a reduction of: hemical purchases; ater use (resulting in lower water and sewer costs); and Wastewater treatment needs and disposal costs.
