Regarding pollutant removals, when operated in 0.1 kg COD/m3-d and 0.02 kg NH3-N/m3-d, the MFCs-algae achieved removals in COD 75 % and ammonia 39 %, whereas the MFCs without algae gave removals in COD 68 % and ammonia 72 %. It appeared that the MFCs-algae exhibited better performance in removing organics, supplying oxygen, and energy efficiency than the MFCs without algae. These findings suggest that membrane-less microbial fuel cells with algae growth in cathode is a promising sustainable technology, which has potential application in water resource management.

碩士 === 國立臺灣海洋大學 === 河海工程學系 === 101 === In this study, both the pollutant removals and electricity generation were examined in two parallel membrane-less microbial fuel cells (MFCs), one having algae growth in cathode chamber and the other one without growing algae. Artificial wastewater contained COD 150 mg/L and ammonia 25 mg/L was continuously discharged into the two MFCs, loaded under 1000 Ω external resistance, and operated at light/dark cycles and hydraulic retention time of 1.4 days.
