Refineries in the cycle of fuel and energy supplying have an incomparable role. Continuous production with attention to non contamination of environment needs to optimization of wastewater and disposal treatment processes and using of new techniques in wastewater treatment plants. Amount of excess biological sludge in Bandar Abbas refinery is 40-50 ton/month. Estimations show that the cost of sludge management in this plant is about 40-60% of total cost. Addition to disposal of this sludge with oily contaminates maybe cause to damage of environment. For minimization of excess sludge in this research used advanced oxidation processes. Results show that using of hydrogen peroxide in compare with ozonation and peroxone had better results. In optimized condition, amount of excess sludge and COD can reduce up to 73.33% and 56.97% respectively.
