In this study, the effects of various operating conditions (reaction time, current intensity, pH and H2O2 concentration) in treatment of old municipal landfill leachates by using electrochemical processes (electroflocculation, electro-Fenton and combined electroflocculation+electro-Fenton) was compared to Fenton's reagent oxidation process. The results of this work showed that, E-Fenton technology may be used efficiently for treatment of old municipal landfill leachates by using appropriate operating conditions. The best removal efficiency was obtained when the following operating conditions were used: reaction time of 30 minutes, current intensity of 2A, H2O2 concentration of 0.5% and pH=3. In these conditions, the removal efficiencies achieved for chemical oxygen demand, colour and turbidity were, respectively: 70±2%, 92±2% and 92±2%. The results obtained by the present study revealed that the E-Fenton electrochemical process was efficient in the removal of high concentrations of chemical oxygen demand, colour and turbidity and could be an environmentally promising alternative for the treatment of mature landfills leachates. Furthermore, this process showed lower energy cost and consumption of electrodes
