Influence of pretreatment and pH on the enhancement of hydrogen and volatile fatty acids production from food waste in the semi-continuously running reactor

Abstract In this study, FW effluent was used as a substrate for both hydrogen and volatile fatty acids (VFAs) production by a lab scale set up of the semi-continuously running reactor system with a mesophilic fermentation to examine the influence of pH and pretreatment. Repeated measurement analysis showed that the factors (pH and Pretreatment) significantly influenced H2, VFAs concentration, VFA/soluble chemical oxygen demand (SCOD), and H2/SCOD traits (P
