ABSTRACT

The aim of this study is to investigate the usability of sewage sludge, a waste from waste water treatment facility, at constant temperature and different pH conditions in the hydrogen production by dark fermentation. It was understood from the results that hydrogen production varies according to the characterization of activated sludge. In the experiments performed at different pH values (pH 4-8) at 35℃, maximum hydrogen production was achieved within the first 24 hours. Except for one performed at pH 8, hydrogen gas release was observed at other pH values within 2 hours. However, according to the results obtained at the 24th hour, maximum hydrogen production (2489 mL/m3H2) was observed at pH 8.
