The aim of this work is the definition of a clean process for the treatment of landfill leachates by integration of efficient technologies, namely electrooxidation and selective ion exchange, that reduce the initial concentration of the pollutants and allow re‐use of the treated water. Treatment of the leachates by electrochemical oxidation using a boron doped diamond electrode led to complete removal of chemical oxygen demand and ammonium nitrogen. However, as a result of ammonium oxidation the partial formation of nitrate was observed. Ion exchange removal of nitrate was experimentally analyzed using the selective resin Purolite A520 E obtaining satisfactory results.
