Ultra-Pure Water System for Car Painting Process

Auto Parts Manufacturer Reverse Osmosis System
May 9, 2024When an auto manufacturer chose to end its engine block casting operations and continue its engine block manufacturing operations, wastewater treatment at the facility needed to reflect the change in effluent. Historically, effluent from the facility met levels that allowed it to be conveyed to the local publicly owned treatment works (POTW) for final treatment. The standard treatment of the oily wastewater from engine manufacturing is oil skimming, coagulation, flocculation, and floating. This physical/chemical treatment reduced oil and grease levels, but without the dilution water from casting operations, the new effluent would not adequately meet POTW requirements. Teaming with the automotive maker’s engineering team, Kleinfelder Water Technologies and membrane vendor-partners determined that engine manufacturing wastewater could be filtered with ultrafiltration (UF) membrane technology under the proper conditions. If the oils used for lubrication of machining, grinding, and cutting are maintained in an emulsion, they will be retained by ultrafiltration membranes. The emulsion is dewatered through this technology, concentrating oils to a marketable product, and producing high quality effluent meeting the POTW’s standards.
