In this study, the effectiveness of the processes of ozon (O3), ozon + hydrogen peroxide (O3 + H2O2) and fenton (Fe2 + H2O2) in the treatment of olive oil supplied from an olive oil production facility operating in the Fishesir province was studied. Initially, the O3 generator was operated with a capacity of 10% and the ozonization process was carried out for 6 hours at 3 different pH values (4.75, 10 and 11), and the maximum yield was calculated at 15.27% when the pH values were set to 11. Secondly, the O3 generator with 10% capacity was run and 500 mg L-1 H2O2 was added to the medium. After 6 hours of this trial, the output was 9.8%. Finally, different Fe2+ (2.014 g L-1 and 4.028 g L-1) and H2O2 (19.05, 44. When the effects of the concentrations of 44 and 80 g L-1) were studied in the fenton process, the concentrations of Fe2+ and H2O2 increased, the COI concentrations remaining in the environment continuously decreased at the end of the test. The Fe2+ concentration is 4.029 mg L-1 and the H2O2 concentration is 80 mg L-1 and the COI reduction is 81.94%. The results found that the fentanyl process was much more effective than other processes.

In this study, the effectiveness of ozone (O3), ozone+hydrogen peroxide (O3+H2O2) and fenton (Fe2++H2O2) processes were investigated in the treatment of olive mill wastewater obtained from an olive oil production facility operating in Balıkesir province. Firstly, the ozone generator was operated with a 10% capacity. Ozonation was performed for 6 hours at three different pH values (4.75, 10 and 11) and the maximum removal efficiency was calculated as 15.27% when the pH value was 11. Secondly, the ozone generator was operated with a 10% capacity and an avarage of 500 mg L-1 H2O2 was added. After this 6 hour experiment, the removal efficiency was obtained as 9.8%. Finally, in the fenton process, where the effects of Fe2+ (2.014 g L-1 and 4.028 g L-1) and H2O2 (19.05, 44.44 and 80 g L-1) concentrations were examined for the treatment of olive mill wastewater, the remained concentrations of COD decreased continuously at the and of the experinent when Fe2+ and H2O2 concentrations increased. The concentrations of Fe2+ and the H2O2 were set at 4.029 mg L-1 and 80 mg L-1 respectively, and COD removal was achieved at the rate of 81.94%. The results obtained from the experiments revealed that the fenton process has much more effeciency than other processes.
