Abstract

In this study, sludge characteristics of anaerobic sequencing batch reactor (ASBR) were investigated to improve and optimize the efficiency of the system converting starch into biohydrogen. The effect of stratification in settling phase on H₂-producing ASBR, which results in settleable and non-settleable sludge, was observed using a batch experiment. It was concluded that specific H₂ activity of decanting non-settleable sludge was higher than that of settleable sludge, which may be the reason of low yield in H₂-producing ASBR. In addition, effect of settling time on settleable sludge, which is another key operational parameter, was also analysed using another set of batch experiment. Settling time of the sludge was found to be an important parameter in H₂-producing ASBR. Specific H₂ activity varied inversely with the duration for which settleable microorganisms were contained in settling phase. Microbial species, responsible for H₂ activity in each condition, were identified using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis.
