Keywords:
Electrocoagulation, color removal, COD, textile wastewaterAbstract
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.
