INFLUENCE OF CURRENT DENSITY ON LEACHATE TREATMENT EFFICIENCY BY ELECTROCOAGULATION WITH ZEOLITE ADDITION

The electrocoagulation with zeolite addition was used to treat compost leachate. The effects of different current densities and zeolite particle sizes on electrode dissolution, electrode surface condition, and removal efficiency were investigated. The surface of the electrodes was analysed by optical microscope, while the consumption of the aluminium electrodes was investigated by weighing. The results confirmed that the removal efficiency could be improved by conducting the experiment at higher current densities, but the electrodes used were significantly more damaged. Significant damage was also observed on the electrode used in the experiment with larger zeolite particles, which can be related to the stronger abrasion effect.
