Application of electrocoagulation for textile wastewater treatment: A review

Abstract

The increasing development of the textile industry is always followed by the amount of wastewater produced. The textile industry uses various types of synthetic dyes, and the amount of dyes is still high in its waste. The impact of the discharge of textile wastewater into the environment without rigorous treatment will damage the environment because the dense color of the waste can prevent light penetration for aquatic organisms. Also, various metals and other harmful chemicals can contaminate soil and water sources. One promising method for treating textile wastewater is electrocoagulation. Electrocoagulation can reduce pollutants in textile wastewater efficiently, cheaply, and reliably. In this review article, an explanation regarding the basis and techniques for processing textile wastewater by electrocoagulation will be presented. Various electrocoagulation operational parameters and their relation to the quality of textile wastewater treatment will be reviewed. In addition, problems and limitations of the application of electrocoagulation as a basis for the development of textile waste treatment in the future will be explained.
