Electrocoagulation

In response to the growing and unavoidable need for water resources, the treatment of contaminant wastewater using different techniques offers promising solutions. Electrocoagulation (EC), as an effective physico-elctrochemical approach appears as one of the emerging technologies in this field. EC, combining the advantages of coagulation, flotation, sedimentation, and electrochemical oxidation processes, has gained considerable attention in recent years. This chapter presents a comprehensive overview of the recent literature on the EC application. It presents a theoretical background on the electrocoagulation process, which presents the interpolation complexity between the different steps of EC process mechanisms. Several hybrid processesHybrid processes incorporating electrocoagulation, electrochemical, adsorptionAdsorption and/or membrane technologies have also been described to demonstrate that the combination of several water treatment processes can improve the efficiency of the process. EC modelling is demonstrated to enhance the model and decrease equipment operation, and enable efficient coupling with different depollution techniques.
