Wastewater is discharged to the local sanitary sewer, which is regulated by a Metropolitan Sewer District (MSD). The MSD has established discharge limits and reports have indicated that the major source of wastewater and primary area of concern is the discharge from the industrial plating shop within the plant complex. This plating shop generates /approximately/1100 m/sup 3/ (300,000 gal) of wastewater per day. Because construction of a new plating shop is currently planned, a complete renovation of the existing plating shop is not economically feasible. The sponsor demonstrated the use of innovative wastewater treatment technologies that will minimize the amount of wastewater generated from the plating processes and maintain compliance with MSD discharge limits until the new plating shop is constructed. The problems at the facility have been analyzed and a treatment system utilizing reverse osmosis (RO), with volume reduction of the RO concentrate by evaporation, has been recommended. The utilization of RO meets the specification for the demonstration of innovative technology. This paper discusses the problem analysis at the plant as well as the results of a pilot scale RO test program currently being conducted. The installation of the full scale unit is dependent on the successful completion of the RO pilot tests. 1 ref., 6 figs., 3 tabs.
