The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H2O2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe2+ concentration on Fenton system for the percentage color and Chemical oxygen demand removal has been studied. The energy per order also calculated for the advanced oxidation process. The ozone-photo-fenton system has been observed that 100% color and Chemical oxygen demand removal compared to other process studied in the present investigation with in 4 hr of treatment time. Electrical energy per order has been calculated for all the process and found that ozone-photo-fenton shows that lesser energy consumption of about 0.01 kWh/m3order1, for the complete color and Chemical oxygen demand removal.
