ADVANCED OXIDATION PROCESS: A remediation technique for organic and non-biodegradable pollutant

Abstract

Pollutants are big threat for the environment. Their imperil nature have disturbed the balance in the ecosystem and have also endangered the existence of the life on the earth. Advanced oxidation process is one of the emerging approach for the treatment of recalcitrant pollutants in nature. The process mainly involves the generation of a strong oxidant, which can easily degrade the pollutants produced from different sources. This review manifests the need of advanced oxidation process, and gives an outline of the different types of advanced oxidation process. It discusses the mechanism, advantages and disadvantages of the various forms of advanced oxidation process. Parameters for a sustainable technology such as technical and economical feasibility of the process, toxicity level and degradation effectiveness of the medium have also been discussed in detail to profess the sustainability of the process. It has potential and efficacy in removal of organic, toxic and non-biodegradable pollutants with minimum harmful effects. The future perspectives provide the room for modification and development and motivates us to overcome the present challenges and achieve better outcomes in future.
