Treatment of Textile Dye Effluent by Electrochemical Method

This chapter discusses the electrochemical aqueous solution-based breakdown of synthetic textile colours. Several dyeing and finishing industries produce a significant amount of dye wastewater. For the treatment of effluent water, the electrochemical technique is being studied. The discharge of textile wastewater likewise rises as there are more textile industries. So, in recent years, the electrochemical degradation of industrial effluents has gained popularity. Conductivity, pH, process detention times, total suspended solids (TSS), heavy metals, emulsified oils, bacteria, and other pollutants from water are operating factors in electrochemical treatment. Utilizing cyclic voltammetry (CV), reactive synthetic textile dyes' electrochemical behaviour has been reviewed. Studies on chemical oxygen demand (COD), UV-Vis, and CV are chosen to assess the effectiveness of degradation. There are numerous additional businesses that require electrochemical technologies for purifying effluent water. Metal recovery, tanneries, electroplating, dairies, textile processing, oil and oil in water emulsion, and other businesses are among them.
