The post treatment water from pulp and paper mill effluent that usually tends to remain some of recalcitrant compounds was treated by advanced oxidation <br /> <br /> <br /> process (AOP). In this research, O3, H2O2 and O3/H2O2 have been chosen as the alternative AOP to be used in the system. This research conducted in a lab-scale <br /> <br /> <br /> reactor made from cylinder-acrylic glass with 1.5 L as its operational volume. The examination of organic (measured as COD) and chloride ion concentrations <br /> <br /> <br /> were conducted to know the effect of oxidants used to the removal efficiency of organic and recalcitrant compounds found in the post treatment water. Experiment started by determining an appropriate cutting time needed for the treatment process. Experiment continues by determining an optimum O3 and H2O2 concentrations which then will be combined in one treatment process. Results shown that treatment by ozonation alone (O3) has been proven to be more effective compared to treatment by O3/H2O2 and H2O2. It was also shown that treatment by using O3 for the post treatment water which studied in this research will be better performed in the neutral condition compared to acid and alkaline condition. The treatment results from the most optimum condition of all variation done have found to be in accordance with the 2nd class criteria in government regulations No. 82/2001 about Water Quality Management and Water Pollution Control.
