In this study has treated leachate with a high load organic and inorganic substances, using a electrocoagulation (EC) process with iron electrode. The treatment was preformed in a batch electrochemical reactor of 0,25 liter capacity with distance between electrodes 1,5 cm. The sample of leachate was supplied from regional sanitary landfill “Ramici”, Banja Luka. Effects of process parameters such as current density, supporting electrolyte and electrolysis duration are investigated on removal efficiencies of total disolved substances (TDS). The maximum removal efficiency is achieved in 90 minutes of treatment (34,58%), at the current density j=25 mA/cm2 and the concentration of supporting electrolyte NaCl=1 g/L.
