Anodic oxidation of a biologically treated leachate on a boron-doped diamond anode

► Electrooxidation of biological pretreated landfill leachate with BDD anode. ► Influence of the leachate dilution and applied current density on the oxidation rate. ► Comparison between experimental data and theoretical kinetic models for organic mineralization. ► Organic matter mineralization improves with the dilution of the leachate. ► Samples without dilution at very low current density are the most favourable experimental conditions regarding energetic costs.
