The Characteristics of Continuous Hydrogen Fermentation with Membrane Bioreactor

説明

This study investigated the characteristics of continuous hydrogen fermentation with a membrane bioreactor (MBR) under mesophilic condition of 35°C. A continuous flow chemostat-type reactor (CTR) was also operated at the same condition for a comparison. The stable hydrogen fermentation without methane production was successfully achieved for 35days in the both reactors at the hydraulic retention time of 9hrs. The following stoichiometric equation was obtained for the stable hydrogen fermentation in the MBR: Glucose→0.86H₂+0.34CO₂+0.1formate+ 0.04succinate+0.25acetate+0.16lactate+0.19propionate+0.5butyrate+0.035biomass (C₅H₉O₃N). The hydrogen production rate in the MBR was 2.45-2.56l/l/day, which was higher by around 2.25 times than 0.95-0.97l/l/day in the CTR. The specific hydrogen and VFAs production rates in the MBR were very lower than that of CTR, indicating that the MBR has more loading capacity. For the MBR, the membrane fouling was found after a continuous operation of 35 days. Based on the results of the batch filtration test and the measurement of extracellular polymer substances (EPS), it could be considered that the decrease of permeate flux was mainly caused by the deposition of EPS on the membrane surface.
