dc.description.abstract | This study was undertaken to investigate the reduction of the hydraulic retention time (HRT) to decrease methane generation and recover hydrogen production during the long-term operation of biohydrogen production in a continuous stirred tank reactor (CSTR) using molasses wastewater. Reduction of HRT can be a simple and economic method to immediately control unfavorable methane generated during continuous operation of a hydrogen production system. The steady-state performance of the CSTR showed a hydrogen content of 41.3 +/- 3.30% and a hydrogen production rate (HPR) of 63.7 +/- 10.01 mmol-H(2)L(-1)d(-1) under an organic loading rate (OLR) of 29.7 g CODL-1 at an HRT of 24 h. Increase in the methane level above 40% during long-term operation caused decrease in the hydrogen content and HPR to 5.9 +/- 1.6% and 2.1 +/- 1.1 mmoL-H(2)L(-1)d(-1), respectively. When methane increased to a high level over 40%, the CSTR at the HRT of 24 h was operated at the HRT of 12 h. Reduction of the HRT from 24 to 12 h led to decrease in the methane content of 12.1 +/- 4.44% and recovery of the HPR value to 48.9 +/- 15.37 mmol-H(2)L(-1)d(-1) over a duration of 13-22 d. When methane is generated in a continuously operated reactor, reduction of the HRT can be an easy way to suppress methanogens and recover hydrogen production without any additives or extra treatments. | * |
