In this study, two fibrous carbon anodes (namely (PNWG) and carbon brush (CB) made from artificial carbon) and bamboo charcoal (BC) were evaluated for current recovery from sewage wastewater. When these anodes were polarized at 0.2 V vs. Ag/AgCl in sewage wastewater, CB produced a maximum current of 2.9 1.5 1.4 A/m 2 . This exceeded that produced by PNWG ( A/m 2 ) and BC ( A/m 2 ). The CB was superior to those achieved with the accumulative charge recovery achieved with other two 1.6-2.2-NWG BC ( and fold higher than that with P and , respectively). During the cyclic voltammetry analysis, CB demonstrated the highest catalytic current with maximum -0.6 0.4 potential in the range of to V vs. Ag/AgCl and the smallest anode resistance (0.20 Ω that the fibrous anodes (CB and PNWG) m 2 ). Direct cell counting revealed attached most the anodes (80%), whereas BC the proportion of of the cells in did not. In contrast,Geobacter species, a representative electrogenic microorganism in the total bacteria, was similar among the three anodes (4.4-5.8%). The observed to be tubular microbial fuel cell (ϕ 5.0 cm core wrapped with an anion exchange ) equipped with an air-chamber membrane A/ 2 . This is higher than those reported in the (AEM) and the CB delivered a current of 1.8 m existing literature for the same microbial fuel cell (MFC) configuration. This indicates that the anode from planar the current the alteration of to brush can contribute toward improving recovery The BC needs improvement to have more through the air-cathode-AEM-MFC. specific surface area, whereas it showed superiority in cost efficiency considering material and processing.
