Treatment of petroleum refinery effluent using electrochemical techniques

Abstract

The present research was undertaken to investigate the potential of electrocoagulation and electrochemical oxidation techniques for treating petroleum refinery wastewater Different types of electrodes have been used in both electrocoagulation and electrochemical oxidation In electrocoagulation aluminium and mild steel were used as the anode While in the electrochemical oxidation ruthenium oxide coated titanium was used as the anode In electrocoagulation the experiments were conducted in a batch newlinereactor The effect of the operating parameters such as the current density pH supporting electrolyte treatment time and anode material was examined The progress of the pollutant removal was measured through COD measurement The electro coagulation mechanism was modeled using adsorption isotherms newline
