In recent years, hard research has been aimed to develop effective technology for the treatment of wastewater and industrial effluent containing organic/inorganic contaminants. Amongst several technologies, the advanced oxidation processes (AOPs) recently have played a major role in the treatment of wastewater. In this study, the treatment of institutional wastewater by solar-photo-Fenton (UV/Fe 2+ /H 2 O 2 ) process based on AOPs was examined in terms of % color, % turbidity, and % COD removal. The solar-UV/Fe 2+ /H 2 O 2 process has revealed a higher removal of color (91%), turbidity (90%), and COD (86%) than the other processes. The effect of various experimental parameters such as hydrogen peroxide (H 2 O 2 ) concentration (0.25 to 1.25 g/L) and Ferrous ion (Fe 2+ ) concentration (0.005 to 0.12 g/L), initial pH (2 to 10), reaction time (30 to 180 min) on the color, turbidity and COD removal has been studied to find out the optimum conditions leading to maximum removal efficiency of the solar UV/Fe 2+ /H 2 O 2 process. The best results of the solar UV/Fe 2+ /H 2 O 2 process of institutional wastewater treatment have been found using 0.75 g/L of H 2 O 2 , 0.045 g/L of Fe 2+ , pH of 4, after 120 min of reaction time. The present study revealed that the solar-UV/Fe 2+ /H 2 O 2 process in an AOPs was well efficient in the institutional wastewater treatment, accomplishing a higher pollutant removal rate. The solar-UV/Fe 2+ /H 2 O 2 process is an effective treatment technique for the removal of pollutants from institutional wastewater.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
