In 21st century, organic and domestic wastes and discharges from varied chemical and manufacturingindustries to water bodies become a critical issue and challenge for the researchers, engineers andpolicy makers. Advanced oxidation processes (AOPs) are efficient, sustainable, economically viableand green techniques to elimination on-degradable organic pollutants by biological and traditionalprocesses. A number of research articles have been published from the past two decades on thewastewater treatment using various advanced oxidation processes. The main objective of this reviewpaper is to provide the quick view for researchers, academicians and scientists in the area of wastewatertreatment using various types of AOPs, which incorporate green principles involves in the processesfor removal of different pollutants and contaminants including dyes, phenols, pesticides, herbicidesetc. from wastewaters, with emphasis on the degradation efficiency of various photocatalysts. Theformation reactions of •OH radical and the mechanisms of degradation of various organic pollutants inthe wastewater is also discussed. This review covers various types of advanced oxidation processes,viz., ozone-based processes, photocatalysis and Fenton-based reactions.
