- Abstract
- The anode of a two-chamber methane-producing microbial electrolysis cell (MEC) was poised at +0.200 V
vs. the standard hydrogen electrode (SHE) and continuously fed (1.08 gCOD/L d) with acetate in anaerobic
mineral medium. A gas mixture (carbon dioxide 30 vol.% in N2) was continuously added to the cathode
for both pH control and carbonate supply. At the anode, 94% of the influent acetate was removed, mostly
through anaerobic oxidation (91% coulombic efficiency); the resulting electric current was mainly recovered
as methane (79% cathode capture efficiency). Low biomass growth was observed at the anode and
ammonium was transferred through the cationic membrane and concentrated at the cathode. These findings
suggest that the MEC can be used for the treatment of low-strength wastewater, with good energy
efficiency and low sludge production. (literal)
