|Title:||COMMERCIAL LAUNDRY WASTE WATER TREATMENT SYSTEM|
The present invention provides a method of treating a commercial or industrial laundry wastewater stream. The method and apparatus treats a commercial laundry waste stream from a commercial washing machine or machines wherein the waste includes total suspended solids, chemical oxygen demand, biological oxygen demand, turbidity, and bacteria. The waste stream is transmitted to a first treatment unit that has a membrane filter that filters particles of between about 6 and 40 nanometers. At the first treatment unit, the waste stream is separated into a permeate stream and a retentate component. The retentate component is transmitted to a second treatment unit that filters particles of between about 3 and 10 nanometers. The permeate stream is then transmitted to a permeate holding vessel after treatment in the second treatment unit. The retentate component is placed in a mixing vessel where it is mixed with a polymer to form a solid waste.
