Pilot scale microbial fuel cells using air cathodes for producing electricity while treating wastewater

Degradation of phenolic compounds in wastewater using a conical-shaped packed-bed microbial fuel cell in continuous flow with recycling

“…Pharmaceutical industries, petrochemical plants, dye processing plants, and textile industries are the potential users of such a device for treating their aqueous organic effluents. 3,4…”

“…Pharmaceutical industries, petrochemical plants, dye processing plants, and textile industries are the potential users of such a device for treating their aqueous organic effluents. 3,4 The use of expensive noble or precious metal-based electrodes and the Naon proton-exchange membrane (PEM) are the major hindrances in scaling up SCMFCs. In this context, the focus of many recent studies is on the development of new electrode materials, including transition metal-carbon nanocomposites, as a potential substitute for the expensive noble metal-based electrodes.…”

Simultaneous removal of organic matter and nitrogen compounds by partitioned aeration in a 226 L-scale microbial fuel cell

“…MFCs are capable of successfully treating domestic wastewater without aeration, even at a > 100 L scale. 6,[12][13][14][15][16][17][18][19] However, the COD of the effluent from anaerobic MFC was higher than 81 mg L À1 with less than 43 h of HRT and rarely met discharge standards. 6,[12][13][14][15][16][17][18][19] However, there have been few exceptions; dualchambered MFC with an aerated cathode chamber yielded an effluent with a COD 25 mg L À1 .…”

“…20 Thus, MFCs generally require post or partial treatments such as aeration, 21 anaerobic membrane ltration, 22 and activated carbon ltration. 19 Furthermore, partial or post-aeration conferred external oxidizing power for nitrogen removal. The aerated cathode chamber of dual-chambered MFCs 20 successfully removed nitrogen from municipal wastewater.…”
