REDUCTION OF COD AT SOURCE USING ADVANCED OXIDATION PROCESS IN AN ACTIVE PHARMACEUTICAL INGREDIENT EFFLUENT

ENVIRONMENTAL ENGINEERING

Advanced Oxidation Process (AOP) is the emerging technology used for Wastewater treatment. This study has been carried out on lab scale test and lab scale pilot plant to the effectiveness of the Advanced Oxidation Process (AOP) technology. AOP is basically the delivery of strong chemical oxidants to the subsurface for the purpose of treating organic contaminants and COD. The objective of this paper is to evaluate the potential of Advanced Oxidation technology to remove COD in wastewater and also provides an overview of two different oxidants that are mainly used in AOP: Hydrogen peroxide as (Catalyzed Hydrogen peroxide) (i.e. modified Fenton’s reagent) and Sodium Persulfate. Each of these oxidants used has their own unique characteristic and the ability to react with contaminants in subsurface; for example, CHP which is a non-selective oxidizing and reducing agent shows degradation results with almost all types of sorbed and non-aqueous contaminants but has lowest stability inside subsurface when injecting for treatment. Persulfate is the latest and least investigated oxidant. It has the potential of both stabilizing and widespread reacting with the contaminants in the subsurface. . Since, these oxidants are reliable enough to treat the contaminants, so, while wastewater treatment with AOP the problem of COD in Wastewater could be sorted out. Although none of these oxidants are ideal to use for Wastewater treatment, but still, have the ability enough to treat the contaminants appropriately than any other AOP technologies being used.
