Textile processing units in Erode, Karur, Salem and Tirupur districts of Tamilnadu, India generates chemically toxic waste water there by polluting sub-soil and surface water of water bodies in particular River Cauvery. In Erode district, a model Common effluent treatment plant (CETP) was promoted by State Industrial Promotion Corporation of Tamilnadu Ltd, at Perundurai with 14 textile units as stake holders. Waste water from textile processing units contains a complex mixture of dyes, which are highly resistant to conventional treatment technology. As the characteristics of wash water effluent and dye bath effluent are variable, various physical, chemical and biological treatment methods are adopted for the treatment. Most of the perennial rivers in Tamilnadu have less surface flow water and dried during summer season. Due to this non-sustainability condition of water source of Cauvery River, all the processing industries are facing high production loss and necessitated treating and reusing the wash water effluent using a novel technology. In this study, Reverse Osmosis technique is adopted to treat the wash water effluent and reuse the membrane treated wash water for processing textile products there by aiming for zero discharge to protect green environment. Based on the experimental results an embedded system membrane method with biological treatment is best suited for effective recovery of permeate. 

 

Key words: Reverse Osmosis, Wash water effluent, Dye bath effluent, zero discharge
