Electrochemical Treatment of Arsenic-Polluted Waters by Electrocoagulation Process

Arsenic is naturally a toxic metal and is found in surface and ground water of many parts of the world. Due to the low efficiency of conventional treatment methods for achieving the standard of level (10 pg/l), it is necessary to find a new and economical method to reach this standard. Electrocoagulation process is the distinct economical and environmental choice for water and wastewater treatment. In a typical electrocoagulation process, a sacrificial electrode (Anode) is decaling to release coagulant precursors into solution. In this paper, electrocoagulation process and its affecting factors has been discussed as an effective method for arsenic removal from drinking water. The desired results were obtained by iron electrodes, which are the safest electrodes in this treatment process.
