The present work evaluated the biohydrogen production from a 0.4 L upflow anaerobic sludge blanket reactor type (UASB) operating at psychrophilic temperature (21 ±2 °C) at different feeding strategies varying hydraulic retention times (HRT) and sucrose concentration in the feeding. First strategy (24h/31c) fed semi-continuously 31 gsucrose L-1 at 24 h HRT; second strategy (12h/19c) fed semi-continuously 19 gsucrose L-1 at 12 h HRT; third strategy (4h/8c) fed continuously 8.3 gsucrose L-1 at 4 h HRT. After 70 days of operation, the UASB accumulated 65.44 L H2. The average HY for the whole operation during the three strategies was 62.6 NmL H2 gsucrose-1 , and average hydrogen content was 69.04%. In general terms, the best operation strategy was 12h/19c since it presented good set of results, the best HY (70.6 NmL H2 gsucrose-1) and a comparable hydrogen production rate (2.6 L (L d)-1) to that obtained in 4h/8c strategy (3.17 L (L d)-1). The average gross energy potential rate from the 12h/19c strategy was 46.21 kJ (L d)-1 , whereas energy heating losses were circumvented due to operation at psychrophilic regime. Indeed, psychrophilic or room temperatures should be broadly regarded as an effective alternative towards net energy gains in biohydrogen production.

“…Different studies on the effects of volatile fatty acids (VFAs) [56], pH [57] and organic loading rate (OLR) [58] using POME were also done, either using single stage or integrated reactors. Studies using a single-stage reactor revealed that the biogas production rate could be accomplished at a HRT of 1.5 days and the system was capable to effectively treat POME [40].…”

In recent years, production of biohydrogen and biomethane (or a mixture of these; biohythane) from organic wastes using two-stage bioreactor have been implemented by developing countries such as Germany, USA and the United Kingdom using the anaerobic digestion (AD) process. In Thailand, biohythane production in a two-stage process has been widely studied. However, in Malaysia, treating organic and agricultural wastes using an integrated system of dark fermentation (DF) coupled with anaerobic digestion (AD) is scarce. For instance, in most oil palm mills, palm oil mill effluent (POME) is treated using a conventional open-ponding system or closed-digester tank for biogas capture. This paper reviewed relevant literature studies on treating POME and other organic wastes using integrated bioreactor implementing DF and/or AD process for biohydrogen and/or biomethane production. Although the number of papers that have been published in this area is increasing, a further review is needed to reveal current technology used and its benefits, especially in Malaysia, since Malaysia is the second-largest oil palm producer in the world.

“…[ 8 ] Dark fermentation can result in a relatively high hydrogen production rate (HPR) considering that the conversion occurs at almost ambient conditions. There is also the option of using a wide range of carbohydrate‐rich organic wastes including discarded molasses, [ 9 ] dairy effluent, [ 10 ] sewage sludge, [ 11 ] and palm oil mill effluent (POME), [ 12,13 ] thus enabling treatment to reduce pollution levels while generating high‐value hydrogen gas. [ 14 ] These favorable aspects make dark fermentation a promising technology to produce hydrogen gas.…”

“…The fixed‐film (FF) that was positioned at the top section enhanced the bioreactor in addressing setbacks of up‐flow anaerobic sludge blanket (UASB), by helping to retain a high concentration of biomass and prevent sludge washout in the reactor. [ 12,24,25 ] Experimental data are used in modeling the biological processes, which is essential in understanding the kinetic process. This would provide a basis for process control and optimizing the operational and environmental parameters on the substrate consumption rate.…”

A start-up study for biohydrogen production from palm oil mill effluent (POME) is carried out in a pilot-scale up-flow anaerobic sludge blanket fixed-film reactor (UASFF). A substrate with a chemical oxygen demand (COD) of 30 g L −1 is used, starting with molasses solution for 30 days and followed by a 10% v/v increment of POME/molasses ratio. At 100% POME, a hydrogen content of 80%, hydrogen production rate of 36 L H 2 per day, and maximum COD removal of 48.7% are achieved. Bio-kinetic coefficients of Monod, first-order, Grau second-order, and Stover-Kincannon kinetic models are calculated to describe the performance of the system. The steady-state data with 100% POME shows that Monod and Stover-Kincannon models with bio-kinetic coefficients of half-velocity constant (K s) of 6000 mg COD L −1 , microbial decay rate (K d) of 0.0015 per day, growth yield constant (Y) of 0.786 mg volatile suspended solids (VSS)/mg COD, specific biomass growth rate (max) of 0.568 per day, and substrate consumption rate of (U max) 3.98 g/L day could be considered as superior models with correlation coefficients (R 2) of 0.918 and 0.989, respectively, compared to first-order and Grau's second-order models with coefficients of K 1 1.08 per day, R 2 0.739, and K 2s 1.69 per day, a = 7.0 per day, b = 0.847.
