Leachate is a complex solution of contaminants produced from municipal waste compacting stations, being primarily comprised of household waste. In this research, leachate was treated in an electrochemical batch process with a dissolved air floatation system using aluminium as the anode with cathode electrodes. Conditions such as pH, current density (i), contact time, and air flowrate were varied and tested to determine their effects on the removal efficiency in terms of Chemical Oxygen Demand (COD), Oil, and Turbidity (Turb.). Under the best conditions, the removal efficiencies for oil, COD, and turbidity were 78.7%, 77.5%, and 98.6%, respectively, suggesting that this method can be considered an efficient and effctive treatment for leachate.
