Pengaruh pH Umpan dan Rasio COD/H2O2 terhadap Penurunan COD pada Limbah Cair Rumah Sakit Melalui Metode Fenton

Hospital wastewater is accumulative wastewater originating from hospital activities, both medical and non-medical. This hospital wastewater has a high enough COD level of 580.65 ppm so it needs to be treated so as not to pollute the environment because the hospital wastewater quality standard that can be discharged is 80 ppm. The Fenton reaction is one of the advanced oxidation processes (AOP) methods that have been widely applied for the treatment of wastewater containing organic pollutants and contaminants. This method utilizes hydroxyl radicals (OH*) produced from the reaction of H2O2 with the catalyst Fe2+ or Fe3+. Hospital wastewater treatment is carried out to determine the ability of the method of Fenton in reducing levels of Chemical Oxygen Demand (COD) and determining conditions. optimum for hospital wastewater treatment using the Fenton method. The parameters that are considered to affect the Fenton process are the COD / H2O2 ratio, and pH. From the results of the research conducted showed that the optimum conditions in this Fenton process are at pH 3 and the COD / H2O2 ratio is 10 (g / g) where the reduction in efficiency decreases in COD levels to 55.07%
