Treatment of Leachate by Electrochemical Oxidation using Graphite and Titanium Electrodes

Abstract

Leachate originating in landfills where municipal solid wastes are disposed is a wastewater with a complex composition that could have a high environmental impact.The study aims to treat the landfill Leachate by electrochemical oxidation process in order to render the Leachate reasonable for inland disposal. Electrochemical oxidation of organic compounds from Leachate is a compelling method of breaking down pollutants which are resistant to biological degradation. The electrodes used in the process are graphite and titanium electrodes. At optimum conditions, the percentage removal by Graphite electrodes areCOD, TDS, Ammonia and Chloride were 52%, 57%, 60% and 45% respectively. The percentage removal by Titanium electrodes are COD, TDS, Ammonia and Chloride were 68%, 80%, 65% and 58% respectively.
