摘要：
Produced water is the largest wastewater stream generated in the oil and gas industries. In this study, experiments were carried out using a bench-scale electrochemical cell using flow-by porous graphite electrode, for oxidation of organic matter in produced water which was collected from natural gas processing field (real sample). The effect of anodic current density and influent feed flow rate on chemical oxygen demand (COD) removal efficiency, and energy consumption were investigated. The maximum removal efficiency of 66.52% was obtained for a flow rate of 50 mL/min, current density of 1.41 mA/cm(2) and pH of 7.3 for an influent COD of 2845 mg O-2/L. The energy consumption at these conditions was 2.12 kWh/kg(COD).
