Electrochemical reactions, electrofiltration process

Apart from electrokinetic phenomena, the electrofiltration process may also be affected by the electrochemical reactions that occur at the electrodes. A typical cathodic process and anodic process in aqueous systems are the formation of hydrogen gas at the cathode and oxygen at the anode ... 

Electrochemical reactions can be harmful to the filtration processes by causing foaming or pore obstmction due to production of gas. However, anodic oxidation can also be used as a method of removing organic molecules from the effluent. It seems further studies are still needed to justify the role of electrode reactions in electrofiltration. 

Processes whereby purification results by the use of an electrical field, which is not accompanied by decomposition or destruction of the pollutant, can be divided into four different groups electrodialysis (ED), electrofiltration, electrosorption, and electroremediation. The main electrochemical reaction in these types of processes is decomposition of water.
