The impact of electrode material in the treatment of landfill leachate by electrocoagulation process

Abstract

This paper presents the results of the electrocoagulation treatment of leachate by the application of iron and aluminum as an electrode material. It was examined the influence of the current density and electrolysis duration on the removal efficiency of total nitrogen (N). Duration of electrolysis was 30 minutes, and based on the experimental results it was found that the optimal current density is 25 mA/cm2. The highest removal efficiency of total nitrogen, achieved under these conditions, amounts 29.58% by the application Fe-Fe electrode pair, while removal of 7.70% is achieved by application Al-Al electrode pair.
