HARMAN AUTOMOTIVE OPERATES A SOLVENT PAINT SPRAY BOOTH WITH PERIODIC BLOWDOWN. EVERY 2-3 MONTHS THE PAINT BOOTH SUMPS ARE COMPLETELY DRAINED AND 10,000 GALLONS OF WATER IS TRUCKED OFF SITE FOR TREATMENT. A PROJECT WAS INITIATED TO REDUCE COSTS ASSOCIATED WITH BOTH PARTS REJECTS AND PAINT BOOTH WATER DISPOSAL. THE FEASIBILITY OF A FIXED FILM BIOREACTOR WAS EVALUATED TO ALLOW CONTINUOUS OPERATION OF A ZERO AQUEOUS DISCHARGE PAINT SYSTEM.
