Toxicity Remediation of Petroleum refinery Wastewater by Electrooxidation Techniques Using Graphite Electrode

Abstract The present experimental study used a successful advanced electrochemical oxidation process (AEOP) and parallel-plate reactor to investigate the potential of (EO) treatment method for real produced wastewater by Al-Samawah petroleum refinery. In oxidation, several electrodes type were employed, with carbon felt graphite plate serving as anode. Tests total organic compounds chemical oxygen demand have confirmed this. influence numerous operational factors on performance, such current density, supporting electrolyte, distance between electrodes, temperature, has been investigated, well energy consumption. After 1 hour treatment, results obtained at 40°C, 15 mA/cm 2 using anode, that COD removal was 77.509%. And TOC 68.13%, direct Electrooxidation technique 86.802%, 70.662% indirect Electrooxidation.
