Advanced Oxidation Process (AOP) by Membrane Reactors

Advanced oxidation process (AOP) by membrane reactors is a synergistic hybrid of hydroxyl radical reaction and membrane filtration in a single reactor. 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 pesticides, pharmaceuticals, endocrine disruptors, microcystins, geosmin, etc. Although micro-/ultrafiltration membranes are almost complete barriers for particulate matter and pathogens in water, they are limited in removing dissolved organic compounds. Thus, the coupling of membrane filtration with AOP in a reactor provides multifunctionalities and...
