For MFC-Anaerobic Fludized Bed (AFBMFC) hybrid system,
fluidized media such as graphite-granule particles were used as a
comparison as a fluidized media in the MFC [50]. It was observed
that the use of both material can shorted the start-up time, as well as enhances power density and removal of COD. The start-up time
was shortened and removal of COD was higher when activated
carbon was applied in the AFBMFC because of its higher specific
surface and the wearability is better comparatively. In terms of
power generation, maximum power density production of
granule-graphite AFBMFC was 530 mW/m2
, much higher than
410 mW/m2 using a granular activated carbon AFBMFC in the same
reactor. The schematic diagram of an anaerobic fluidized bed with
MFC (AFBMFC) hybrid is as shown in Fig. 5a
