This paper explores the performance of Photovoltaic cell Electro-Fenton oxidation during the treatment of methyl orange wastewater. The treatment setup comprises a photovoltaic cell, a battery, DC to AC inverter and an electrooxidation reactor. Throughout the Photovoltaic cell Electro-Fenton oxidation experiment, the effect of operating parameters like current, H₂O₂, rotation speed and electrolysis time on the total organic carbon and energy consumption were examined. The optimization study was performed by varying the current (0.5-2 mA), hydrogen peroxide (25-100 mg/L), rpm (100- 200), and the electrolysis time (5-15 min) using response surface methodology (RSM) and Minitab-17. The pH and the amount of NaCl in the solution were maintained as 3, 0.2g respectively. The optimization study shows that 98% removal efficiency is achievable, consuming 39.4 kWh/m³ energy.
