Using Vibrating Membranes to Treat Oily Wastewater from a Waste Hauling Facility

A unique membrane filtration system has been installed at several major waste oil hauling operations and manufacturing plants that handle or produce oily wastewater. The system manufactured by New Logic, of Emeryville California near San Francisco, is also being used to process used crankcase waste oil and produce filtrate that can be sold as a higher value bunker oil. The V✧SEP, (Vibratory Shear Enhanced Process), system uses a membrane module with special construction for service with high temperature solvents and waste oils and is able to recover up to 90% of the oily wastewater as clean water. The use of high temperature polymeric membranes has many significant advantages over the conventional methods of oily water treatment. There are dozens of methods used for oil water separation. Each technique has advantages. No one technique is suitable for all situations. V✧SEP has very good overall usefulness. Membranes have the advantage of being simple efficient separating devices to hold back oil, grease, metals, BOD, and COD. They can provide clear permeate which can be sewered or re-used.
