Abstract

The textile production industry uses highly water intensive chemical operations. This industry produces massive levels of wastewater and therefore presents great environmental and economic challenges. In the past, the process of electrochemical (EC) has attracted much attention. It has been a cost-effective and an environmentally friendly process implemented to remove different types of pollutants, including dyes, heavy metals , and organic substances . This process is known for its simple equipment and process and for producing relatively low amounts of sludge. Study has been made to replace the chemical treatment of wastewater containing residual indigo dye from the blue denim manufacturing by electrochemical process with consideration to achieve desired water quality. Present study was conducted to investigate the applicability of the electro-coagulation technique for the treatment of indigo dye wastewater. In this study lab-scale electro-coagulation was carried out for the treatment of indigo dye wastewater at different operating time i.e 15min, 20min, 25min, 30min using Aluminum as Cathode and Mild steel as a Anode, with 15mm and 10 mm electrode spacing, supplying 24v and 10amp. It is observed that the batch which is operated at 10Amp for 30 min has maximum removal efficiency of COD &Color i.e. 95% & 86% respectively at optimum pH 8.3.
