Optimization of Engineering and Process Parameters for Electro-Chemical Treatment of Textile Wastewater Sachin Koshti, Abhinav Rai, S. Arisutha, Prerna Sen and S. Suresh 1 Introduction The textile industry is one of the prevailing industry practicing enormous amount of dyes, fibers and other chemicals in different production practices including dyeing, bleaching and finishing. Approximately 100,000 dyes are commercially available with an estimated annual production exceeding 700,000 tons, and nearly 30 % of these dyes are gone astray along with wastewater. So it becomes a necessity to treat the wastewater before discharge. More than 2500 textile weaving industries and 4200 textile finishing factories are established in India. The major pollutants from textile wastewater mainly including surfactants, finishing agents, metal complexes, inhibitor compounds, ionic compounds, dyeing substances, phosphates, dissolved and suspended solids. Textile wastewater has been observed to have high COD values, strong color, immense TDS and varying pH. Therefore, due to large quantities of pollutants present in wastewater, textile industries suffer a lot of problems in discharging the same. Various methods have been proposed for ef fluent treatment, including Fentons method, ozonation, photochemical treatment, coagu- lation, adsorption, biological method and electrochemical treatment (Khandegar and Saroha 2013). Due to use of numerous chemicals in the physical, chemical and biological methods these are inef ficient for effective treatment. Hence the industrial operators are searching for better methods to solve their wastewater treatment problems. S. Koshti Á A. Rai Á P. Sen Á S.
