Polycyclic Aromatic Hydrocarbon (PAHs) presence is detected through various medium in Malaysia, however there is no regulation on limitation of PAHs disposition to the water system. Conventional biological treatment are not able to completely remove the pollutants from the water system. Photo-Fenton chemical oxidation treatment which utilizes hydroxyl radical are able to degrade recalcitrant chemicals such as aromatic compounds. A photo-Fenton reactor is designed with immobilization of Fe on Nafion membrane for PAHs removal from supply water and performing assessment based on its effectiveness and efficiency. Assessment was done to obtain the optimum settings including hydrogen peroxide concentrations, UV light, and retention time. Total Organic Carbon and Chemical Oxygen Demand is taken as the observance parameter to determine the degradation of PAHs. PAHs presence were determine using UV-VIS scanning spectrophotometer. TOC degradation is observed at 94.6% pollution reduction with optimum reaction time of 85 sec and H2O2 concentration of 0.3 mg/L. COD degradation is observed at 87.7% pollution reduction with optimum treatment time of 70 sec and H2O2 dosage of 0.3 mg/L.
