哈曼汽车公司经营一个定期排污的溶剂喷漆室。每隔2-3个月，油漆间的污水坑就被完全排干，10000加仑的水被卡车运出现场进行处理。启动了一个项目，以降低与零件拒收和喷漆室水处理相关的成本。对固定膜生物反应器的可行性进行了评估，以允许零水排放涂料系统连续运行。

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.
