Treatment Technologies of Textile Dyeing Effluent A Review

Abstract

This review discusses the reuse of textile waste water meet the demand of present situation. Removal of colour and reactive dye is the major process in the treatment. Advanced oxidation process is the better treatment that uses the combination of ozone, hydrogen peroxide and ultraviolet irradiation which is eco-friendly. Since reactive dyes are easily soluble in water, so removal of dye needs activated carbon with adsorption as it has high adsorption capacity and high surface area. Optimization of electrochemical technique for treatment is also effective. In this process copper and stainless steel were chosen as the best anode and cathode. Sodium chloride is used as a supportive electrolyte. An overview of these processes is presented according to their specified features.'
