This study has been attempted to generate electricity, while simultaneously treating artificial organic wastewater using both batch and continuous microbial fuel cells (MFCs). In the batch MFC, current-voltage curve showed an onset potential of -0.69 V vs. Ag/AgCl. The 486 mg/L glucose solution showed the maximum power of 30 mW/m2 and the maximum current density of 75 mA/m2 shown in the power curve. Discharging of the cell containing COD 423 mg/L at the constant current density of 60 mA/m2 showed a continuous electricity generation for about 22 hours that dropped rapidly due to dissipating of organic material. Total electric energy production was 18.0 Wh. The COD treatment efficiency was found to be 72%. In the continuous MFC, COD removal tends to increase as the hydraulic retention time is increased. At one day of hydraulic retention time as the maximum value reaches the COD removal efficiency, power production rate and power production rate per COD removal that were obtained were 68.8%, 14 mW/m2, and 20.8 mW/m2/g CODrm, respectively. In the continuous MFC, the power production rate per COD removal increases as the hydraulic retention time is increased and decreases as the organic loading rate is increased. At the values lower than an organic loading rate of 1 kgCOD/m3/d, the values higher than about 18.1 mW/m2/g CODrm could be obtained.
