Advanced oxidation processes (AOPs) and membrane operations are composed of advanced oxidation followed by membrane filtration, where the former decomposes dissolved organic matter and the latter removes particulate matter. Advanced oxidation process (AOP) is the uncontrolled, destructive action of hydroxyl radicals generated from ozone, H2O2, ultraviolet radiation, Fenton reaction, electrolysis, sonolysis, and photocatalysis (e.g., TiO2). AOP is most widely used for the decomposition of nonbiodegradable organic contaminants present in industrial and municipal wastewaters. It can be also applied for the degradation of micro-contaminants and taste- and odor-causing compounds in drinking water sources, such as pesticide, pharmaceuticals, endocrine disruptors, microcystins, geosmin, etc. This combined process can compensate the weak point of each process, but the oxidants left over should be quenched before their contact with polymeric membranes. This is because oxidants can deteriorate...
