“…In general, hydrogen production after the 48 hours was less and in this study higher hydrogen production was obtained at pH 8. Although in most literature, the production of hydrogen was conduction under acidic pH values [15][16][17], some researchers found higher pH could improve the hydrogen production and the volatile fatty acids [6,18]. Zhao et al [6] performed their studies in a bottle (with 400 mL of the heat pretreated sludge each).…”

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°C, 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/m 3 H 2 ) was observed at pH 8.

-An anaerobic sequencing batch biofilm reactor (AnSBBR) containing immobilized biomass and operating with recirculation of the liquid phase (total liquid volume 4.5 L; treated volume per cycle 1.9 L) was used to treat sucrose-based wastewater at 30 ºC and produce biohydrogen. The influence of applied volumetric organic load was studied by varying the influent concentration at 3600 and 5400 mgCOD.L -1 and using cycle lengths of 4, 3 and 2 hours, obtaining in this manner volumetric organic loads of 9, 12, 13.5, 18 and 27 gCOD.L . Different performance indicators were used: productivity and yield of biohydrogen per applied and removed load, reactor stability and efficiency based on the applied and removed organic loads, both in terms of organic matter (measured as COD) and carbohydrate (sucrose). The results revealed system stability (32-37% of H 2 in biogas) during biohydrogen production, as well as substrate consumption (12-19% COD; 97-99% sucrose). Conversion efficiencies decreased when the influent concentration was increased (at constant cycle length) and when cycle lengths were reduced (at constant influent concentrations). The best yield was 4.16 mol-H 2 .kg-SUC -1 (sucrose load) at 9 gCOD.L -1.d -1 (3600 mgCOD.L -1 and 4 h) with H 2 content in the biogas of 36% (64% CO 2 and 0% CH 4 ). However, the best specific molar productivity of hydrogen was 8.5 molH 2 .kgTVS .d -1 (5400 mgCOD.L -1 and 3 h), indicating that the best productivity tends to occur at higher organic loads, as this parameter involves the "biochemical generation" of biogas, whereas the best yield tends to occur at lower and/or intermediate organic loads, as this parameter involves "biochemical consumption" of the substrate. The most significant metabolites were ethanol, acetic acid and butyric acid. Microbiological analyses revealed that the biomass contained bacilli and endospore filaments and showed no significant variations in morphology between different experimental conditions.

“…Some recent works survey biological hydrogen production in membranes (Bakonyi, Nemest othy, Simon, & Bélafi-Bak o, 2014;Jeong, Cha, Yoo, & Kim, 2007;Lee, Lin, Fangchiang, & Chang, 2007;Oh, Iyer, Bruns, & Logan, 2004). The scarce number of experiences so far is mainly due to the young development of biohydrogen technology itself.…”
