Abstract

Advanced oxidation processes are an efficient method of treating many industrial wastewaters. This study investigated the treatment of olive mill wastewater with the electro-oxidation method. This study investigated data obtained from chemical oxygen demand (COD), total organic carbon (TOC) and total phenol (TP) removal efficiencies for this wastewater. The anode material was Ti/Pt while the cathode material was Ti. The experiments using a batch reactor examined the effects of mixing rate (0–600 rpm), dilution factor (1/5-5/5), pH (2–8), type of support electrolyte (Na2SO4, KCl and NaCl), concentration of support electrolyte (0.25–1.25 M) and current density (2.5–15 mA/cm2) on COD, TOC and TP removal efficiencies. The study found the COD, TOC and TP removal rates under optimum conditions were 100%, 78% and 100%.
