Continuous fermentative hydrogen production from low strength sago mill effluent in a continuously stirred tank reactor (CSTR)

Abstract

The feasibility of continuous hydrogen production from sago mill effluent via anaerobic fermentation was conducted in a continuously stirred tank reactor using mixed microbial consortia under mesophilic conditions. Low strength sago mill effluent at 3 g SC/L were utilized and its effects at varied hydraulic retention time (HRT: 12, 8, 6 and 4 hours) on biohydrogen production were investigated. The maximum hydrogen production rate (HPR) was obtained at 4.6 L H2/L. day the under organic loading rate (OLR) of 26.3 g SCconsumed/day and HRT 4 hours. Hydrogen yield (HY) meanwhile was highest at 277 mL H2/g SCconsumed from HRT 8 and 6 hours corresponding to OLR of 14.2 and 18 g SCconsumed/day respectively. At optimal HPR and HY, the primary soluble metabolites were dominated by butyric acid followed by acetic acid and ethanol thus suggesting to a butyrate type fermentation pathway.
