【 摘 要 】

Evaluation of Chemical Oxygen Demand (COD) removal by a dielectric barrier discharge (DBD) system to produce biogas from palm oil mill effluent (POME) was investigated in a batch experiment. The residence time was set at 1 hour. The batch experiments were observed with voltage variation at 10, 15, 20 and 25 kV. It was found that the COD removal was measured at 22.47% to 44.94% with the applied voltage was set at 10-25 kV, respectively. The results also shown that the maximum yields of hydrogen and methane by the system were 7.94 and 1.78 mL/mL of POME, respectively that were obtained at an applied voltage of 25 kV.
