Abstract
Effects of different pretreatment methods on sludge inocula were evaluated with respect to hydrogen (H 2) production enhancement using palm oil mill effluent (POME) in a batch system. The experimental results showed that the pretreatment methods (chemical, acid, heat-shock, freezing and thawing, and base) at 35 °C and initial pH 5.5 had a positive influence on H 2 production yield and chemical oxygen demand (COD) removal efficiency during the fermentative H 2 production as compared to the control experiments (without pretreatment). Heat-shock pretreatment method was shown to be a simple and useful method for enhancing both H 2 producing and COD removal processes from POME with highest H 2 yield and COD removal efficiency at 0.41 mmol H 2/g COD and 86, respectively. © 2011 Elsevier Ltd.
