Efficient Electrochemical Advanced Oxidation Process for Water Treatment

Stanford researchers have developed an efficient electrochemical pathway for hydroxyl radicals (*OH) production for advanced treatment trains for purification of municipal wastewater for potable reuse. Current method of OH production uses UV light splitting of H₂O₂ which is less efficient due to the low absorption coefficient of H₂O₂ and only about 10% use of H₂O₂. This new electrochemical advanced oxidation process (AOP) requires lower H₂O₂, uses the H₂O₂ more efficiently and can avoid the use of expensive electrode materials. Demonstration of electrochemical dissociation of H₂O₂ has been demonstrated with a low-cost stainless steel electrode.
