Pollutants in drinking water above permissible level may prove to be hazardous to human health. The present study was carried out to assess the ability of electrocoagulation with Iron and Aluminium electrodes for water treatment process. Electrocoagulation presents a robust novel and innovative alternative in which a sacrificial metal anode doses water electrochemically. This has the major advantage of providing active cations required for coagulation, without increasing the salinity of the water Electrocoagulation is a complex process with a multitude of mechanisms operating synergistically to remove pollutants from the water. A wide variety of opinions exist in the literature for key mechanisms and reactor configurations. A lack of a systematic approach has resulted in a myriad of designs for electrocoagulation reactors without due consideration of the complexity of the system. A systematic, holistic approach is required to understand electrocoagulation and its controlling parameters. In this project, electrocoagulation with Iron and Aluminium electrodes will be carried out and a comparative study will be investigated. Several key parameters affecting the efficiency of electrocoagulation will be investigated with laboratory scale experiments in search of optional parameter values. Optimal values of parameters will be determined on the basis of the efficiency of hardness removal from ultrafine suspensions. Various parameters that would be studied are pH, chlorine content, alkalinity and Voltage. Parameters affecting electrocoagulation process, such as initial pH, applied voltage, COD and time of electrocoagulation process would be investigated
