Abstract

The science of electrocoagulation is similar to an electrolysis. Here the anode continuously disintegrates due to the electrical current flowing though it produces cations which attract the pollutants in the wastewater. The cations released in water are produced in situ and acts as the electrocoagulant in this case. The dyes attached to the electrocoagulant either precipitates or flocculates, thereby separated. This is perhaps one of the advanced technologies where the system is very robust, efficient, and easily controllable requiring minimal maintenance. The chapter presents the details of the electrochemical science behind the electrocoagulation technique and further explains the engineering considerations in dealing with practical implementation.
