ULTRAFILTRATION (UF) HAS BEEN AN ACCEPTED AND HIGHLY SUCCESSFUL METHOD OF TREATING METALWORKING FLUIDS FOR OVER 15 YEARS. AS WASTE WATER DISCHARGE REQUIREMENTS BECOME MORE STRINGENT, ULTRAFILTRATION ALONE MAY NOT BE ADEQUATE. MORE RESTRICTIVE LIMITS ON CHEMICAL OXYGEN DEMAND (COD), BIOLOGICAL OXYGEN DEMAND (BOD), AND OIL AND GREASE WILL DICTATE FURTHER TREATMENT SUCH AS REVERSE OSMOSIS (RO) TO POLISH UF PERMEATE AND PERMIT ITS SAFE AND LEGAL DISCHARGE. ULTRAFILTRATION AND REVERSE OSMOSIS ARE MEMBRANE-BASED TECHNOLOGIES WHICH REDUCE THE VOLUME OF INDUSTRIAL WASTE WATER. DESPITE THEIR COMPLEX MEMBRANE TECHNOLOGIES, UF AND RO SYSTEMS ARE SUPRISINGLY SIMPLE TO UNDERSTAND, OPERATE, AND MAINTAIN. THEY ARE SAFE FOR BOTH THEIR OPERATORS AND THE ENVIRONMENT.
