Electrocoagulation (EC) treatment can be used as an effective alternative to the existing treatment methods. It is a distinct, economical and an environmental friendly choice for meeting water treatment discharge standards and compliance requirements. Due to improved material of construction and process design, the EC process is widely accepted. Presently, this process has gained attention due to its ability to treat large volume of effluent with low cost. The EC process includes the in-situ generation of coagulants via the electro-dissolution of a sacrificial anode, which is usually made up of iron or aluminum. This paper presents a review of the research works available in the open literature on the electrochemical treatment of industrial effluent such as textile, pulp and paper, paint, food, electroplating, distillery, etc. The mechanism and design consideration for electrochemical treatment of wastewater is also presented.
