Abstract: This study reveals comparison between electro-Fenton (EF) and electro-oxidation (EO) methods to study chemical oxidation demand (COD) removal from synthetic petrochemical wastewater. Initially 54.60% of COD removal was found by acid precipitation treatment at optimum conditions. Subsequently, electrochemical treatments such as EF and EO using graphite electrodes were imposed to the supernatant and process parameters such as time (20→80 min), current density (60.97→121.95 A/m2), pH (2→6), Fe2+concentration (1→2 mmole/L), electrolyte concentration ((Formula presented.)), and electrode gap (1→5 cm) were optimized by Box Behnken Design. Maximum removal of COD was obtained 66.23% and 56.57% with electric energy-consumption (kWh/kg CODremoved): 33.30 and 35.27 during EF and EO treatments respectively at optimum conditions. © 2020 Taylor & Francis Group, LLC.
