| Abstract |
This report describes the feasibility of a rinse-and-recovery system that can be installed in almost any metal finishing line and does not harm the environment because no plating solution exits to the sewer. Most toxic pollutants from metal finishing operations are associated with the water used to rinse the affected parts successive finishing operations. A typical car bumper plating operation was chosen as opposed to a barrel rolling operation. When a part emerges from the plating bath, it 'drags out' full-strength plating solution with the bumper. This drag out is tremendously diluted by following rinse steps. The diluted rinses are sent to the sewer and cause toxic deteriorization of the waste waters. The Zero Discharge System is an innovative system for use in the metal finishing industry. A conventional multistage aqueous rinsing system is replaced by a 2-stage solvent spray rinse followed by a single-stage aqueous immersion rinse. By continuously purifying and recycling the baths, appreciable savings in operating chemical costs can be realized. |
