ABSTRACT: Electrocoagulation (EC) is a very efficient process in dealing with effluent streams and separating complicated contaminants prior to the discharge of the treated water. Attention to such a technique augmented thanks to its large set of utilizations, zero—or minimal—chemical dosing demands, low waste formation, and low price. EC appears as an efficacious option to traditional water treatment techniques for the separation of a large collection of contaminants. This work examines the theories of the EC method and its application for the separation of contaminants from wastewater streams. Such a technique depends on the integration of electrochemical and coagulation methods. Basic parameters that touch the effectiveness comprise the electrode material (Fe or Al), current density, the electrical charge per unit volume, and solution pH. Electrode fouling could constitute a hard running dare even if it could be reduced by the alternating current operation. Next studies have to follow the routes of the EC technique for numerous kinds of pollutants at a set of working parameters, in particular for continuous mode, and the expansion of convenient models that could be utilized for scale-up and techno-economic evaluation of EC is required. Running as a destabilization agent and aiding to separate contaminants from the wastewater, the electric field should attract more attention to highlight its key contribution.
