ABSTRACT
This study designed to enhance the energy recovery by the microbial fuel cell (MFC) fed with palm oil mill effluent. The maximum voltage output of 267.1 ± 5.5 mV and power density of 344.3 ± 8.6 mW/m2 were obtained with MFC operated at sludge retention times of 70 days, 1.25 gCOD/L/day organic loading rate, 7 g/L of activated carbon with an average particle size of 60.232 µm. It also had the relatively lower internal resistance and biogas yield at 156 Ω and 111.5 ± 11.4 mL/gCOD, respectively. It also had the highest coulombic efficiency (CE) at 3.06 ± 0.61% and the COD removal efficiency amounted to 91.90 ± 0.44%.
