Advanced oxidation process treatment method has been adapted to olive oil mill wastewater (OMW) for treatability in conventional plants by the aim of sludge minimization. Lots of olive oil mills have facilities in the Aegean Region, Turkey. Wastewater, used in this study, was collected from these factories. Because of the advanced and expensive treatment methods of this wastewater, regulations and limitations are ignored. 95 °C temperature and 10 bar pressure conditions were used with H2O2 as an oxidant in wet oxidation method. Over 96% of oil-grease and 48% of chemical oxygen demand (COD) removal were achieved using wet air peroxidation in conditions with 2.5 mL H2O2/100 mL in 1 h. The influence of hydrogen peroxide with temperature and pressure makes the oil in wastewater soluble and in that way can be treatable in conventional plants.
