Abstract :In this study, Chemical Oxygen Demand insert ignore into journalissuearticles values(COD); removal efficiency from wood processing wastewaters by Fenton Process insert ignore into journalissuearticles values(FP); and Photo Electro Fenton Process insert ignore into journalissuearticles values(PEFP); were examined. Important operating parameters such as pH, Fe+2 concentration/insert ignore into journalissuearticles values(amper for PEFP);, H2O2 concentration and reaction time were optimized. Optimum operation conditions of the FP were pH 3.5, 1.4 gr/L Fe2+ concentration and 50 gr/L H2O2 concentration and 150 min. reaction time while they were pH 3.00, 9.99 mA/cm2 current density and 70 gr/L H2O2 concentration and 150 min reaction time in PEFP. At the optimum conditions, COD removal efficiency of FP and PEFP was 91% and 99%, respectively. Sludge production of FP was 20% higher than PEFP at the optimum conditions.
