| Abstract | ||
| The present work evaluated the use of photo-Fenton process (UV/H2O2/Fe2+) for the treatment of oily aqueous solution using batch system. The photo-Fenton best operating conditions, such as time, pH, oil concentration, H2O2 dosage, Fe2SO4.7H2O concentration and temperature were evaluated. The efficiency of the treatment was measured by COD (chemical oxygen demand) removal. The results showed that the optimum pH for the photo-Fenton process was equal to 3. The increase in H2O2 application resulted in an efficiency increase of the photo-Fenton process at 800 mg/l, the optimum Fe2SO4.7H2O concentration found was 60 mg/l. It was found that the optimal temperature for the Photo-Fenton processes 30oC. Oil concentrations were varied and lower concentration was removed more efficient. Photo-Fenton process gave a maximum COD reduction of 80.59 % (COD from 2684 to 521 mg/l) after the total reaction time (180 min) at optimal operation conditions. | ||
