EMERYVILLE, Calif.(AP) -- New Logic Intl., a leading manufacturer of proprietary membrane filtration systems, announced the successful testing of their VSEP technology on a "zero-discharge" industrial laundry application. The objective of this test was to demonstrate a more economical and environmentally sound wastewater treatment alternative which incorporates almost 100 percent water recycling and reduces sewer discharge to zero. The test was conducted with New Logic's VSEP pilot equipment on wastewater provided by California Linen Rental Co., a major industrial laundry located in Oakland, California.
The primary objective of this application test was to reduce the concentrated waste from California Linen wastewater to an insignificant quantity of disposable sludge. After processing a total of 2,757 gallons of the industrial laundry wastewater, only 1 gallon of fresh water was required for make up water. The remaining 2,756 gallons of recycled clean water is available for re-use. The concentrated waste was reduced to only one gallon of sludge appropriate for landfill disposal. No chemicals were required to facilitate the VSEP wastewater treatment process. This test demonstrated that a "zero- discharge" industrial laundry wastewater treatment with VSEP is quite feasible, an environmentally attractive and cost-effective alternative for many laundry operations.
New Logic's system uses a proprietary Vibratory Shear Enhanced Process (VSEP) which generates a shear force ten times greater than that of conventional filter equipment. As a result, VSEP can process streams containing a variety of contaminants without the fouling problems exhibited by conventional membrane systems. The system not only filters suspended solids, but it also reduces or eliminates BOD, COD, and color bodies.
