Using an anaerobic digestion tank as the anodic chamber of an algae-assisted microbial fuel cell to improve energy production from food waste

Microbial fuel cells present an emerging technology for utilizing the metabolism of microbes to fuel processes including biofuel, energy production, and the bioremediation of environments. The application and design of microbial fuel cells are of interest to a range of disciplines including engineering, material sciences, and microbiology. In addition, these devices present numerous opportunities to improve sustainable practices in different settings, ranging from industrial to domestic. Current research is continuing to further our understanding of how the engineering, design, and microbial aspects of microbial fuel cell systems impact upon their function. As a result, researchers are continuing to expand the range of processes microbial fuel cells can be used for, as well as the efficiency of those applications.

Main Components

The microbial fuel cell (MFC) constructed by a modified Continuous Stirred Tank Reactor (CSTR) which was used as acidification-phase of two-phase anaerobic digestion system. The experiment was operated as batch mode at mesophilic condition (35°C) to evaluate continue voltage output using cattle dung as substrate in hydrolysis-acidification process. The results illustrated that electricity generation increased noticeably to 300mV after 3 days operation, reached 430mV after 20 days and stabilized electricity generation from 420mV to 470mV in the following 70 days. The pH decreased from 7.15 to 6.65 after 15 days operation and maintained stability from 6.4 to 6.8. The main components of VFA in anode chamber were acetic, propionic and butiric acids. The dominating VFA was acetic acid that predominated untile day 50 and the maximum propionic acid concentration was 15% of total VFA.
