ABSTRACT
Textile dyes are the molecules designed to impart colour to the textile fabrics. Wastewater generated by the textile industry is known to have most polluting in terms of quality and quantity. Electrocoagulation proves to be an effective technique for textile wastewater. There are several processes viz. physical, chemical, biological which are widely used for the color removal. Currently, number of absorption process are used for removal of different classes of pollutant especially which are not easily biodegradable. Most widely used process used adsorbent is activated carbon. In this review paper, a comparison of different types of absorbent such as activated carbon, orange peel + banana peel and chitosan along with the conventional electrocoagulation technique is made for removal of color along with COD.
