The continued increase in the costs of chemicals, energy and water makes their recovery more important today than it was years ago when separation techniques by membrane filtration were first introduced to the textile industry. The aim of introducing membrane filtration is not only to reduce water consumption and wastewater streams. The paper describes the results of research works and implementation project concerning cleaner technology and water reuse in textile dye house by TiO2 @PVC composite membrane. Fabricated membranes were characterized with various analytical and experimental techniques. Results showed that the TiO2 blend TiO2 @PVC composite membrane were nano porous in nature with improved porosity and permeability. Addition of TiO2 improved the mechanical stability and water permeability of the composite membranes.TiO2 doped membrane showed better dye rejection behavior with a permeate flux. Size and charge based exclusions along with adsorption were identified as the separating principles. Fouling analysis clearly showed that TiO2 incorporated membranes possessed better antifouling effect than membrane without TiO2 .Thus the TiO2 blended TiO2 @PVC composite membrane are promising for the treatment of dye polluted wastewater.
