Textile waste water generating from dyeing and finishing processes is categorized as high strength waste water due to its strong color and high COD. It is a growing as a major source of environmental pollution. The variability in composition of textile effluent has become hard to treat for conventional treatment processes. Electrocoagulation process can be considered as a reliable, safe and economically feasible method for treating textile effluent. Electrocoagulation treatment of textile waste waters have been analyzed on a bench scale by several researchers and found good results with regard to removal of COD, color, turbidity and dissolved solids at varying operating conditions. In the present review electrocoagulation principle and its application in textile waste water treatment were discussed.
