The effect of fenton oxidation on the quality of pharmaceutical industry wastewater: a case study of bod, cod, toc, and turbidity parameters

Abstract Chemical residues from pharmaceutical manufacturing processes possess the potential to pollute the environment, particularly the aquatic ecosystem. Environmental indicators include COD, BOD, TOC, and turbidity levels that exceed limits set by regulations. This research is focused on investigating fluctuations in the quantities of wastewater contaminant parameters from pharmaceutical manufacturing facilities before and after treatment with the fenton oxidation method, as well as examining the effectiveness of the fenton oxidation process on water quality using predetermined parameters. This study involves independent variables that included various dosages of Fe2+ and H 2 O 2 . Adjusting the pH of the water after stirring to 7 stimulates the flocculation process, which effectively eliminates contaminants, specifically variant 15g FeSO4 and 100 ml H 2 O 2 which successfully lowers turbidity by 99.55%, reduces BOD by 60%, COD removal by 98.69%, and reduces TOC by 92.94%. Control variables include initial contaminant amount, pH, temperature and pressure, fenton oxidation process duration, and instrument conditions.
