Electrochemical Water Treatment

 Electrochemical oxidation (EO) as electrochemical method is different by three aspects. The first is that is the most versatility process in water treatment area and covers: various industrial effluent treatment including, amongst others, distillery, agrochemical, pulp and paper, textile dyes, oilfield and metal plating wastes; hazardous effluent treatment including hospital wastes; removal of pathogens and persistent, pharmaceutical residues and biological from municipal wastewater treatment plant; removal of organic micro-pollutants such as pesticides and heavy metals such as arsenic and chromium from water. Electrochemical oxidation is complementary with most other methods: chemical or electrochemical, and is often combined with one or more of them. And finally, this procedure is the most interdisciplinary of all. It includes: material science, (micro) biology, (electro) chemistry, environmental protection, water supply systems, etc. The most usual water treatment processes are electrocoagulation, electro flotation, electrochemical oxidation, electrochemical reduction and electro deposition. Alkaline water electrolysis (AWE) is classified and influenced by four factors of anode, cathode, separator and cell structure of electrolyze
