Treating wastewaters from manufacturing processes is mandatory before discharging them to the environment. Domestic and industrial wastewaters often contain a certain level of organic substances which need biological treatment. Microbial electrolysis cells (MECs) are especially suitable for this purpose in that both wastewater treatment and hydrogen production can be achieved simultaneously. Microorganisms immobilized on the anode surface take organic substances as substrates, decomposing into carbon dioxide, protons, and electrons. Upon some external voltage bias, protons and electrons combine to hydrogen at the cathode under the anaerobic condition. Here we show that the exclusive H2 production is possible when acetate was used as a substrate. Also, we have applied MEC technology to treat domestic wastewater for H2 production. We found that CH4 instead of H2 was produced under the low voltage bias but H2 portion increased with increasing bias. We present how the experimental conditions can change the gas composition and how to mainly produce hydrogen from wastewater.
