“…The lack of observable methanogenic activity in this study is consistent with the previous findings reported for hydrogen producing anaerobic membrane bioreactors [3]. cmHg -1 ) and practical separation selectivity of the membrane were computed according to the procedure described in our recent publication [11], except the estimation of the driving force, which was done here by Eq. 1.…”

“…Besides the traditional AnMBR arrangement relying on porous water filtration membrane modules, MBRs integrated with gas separation seem also attractive designs to enhance the feasibility of dark fermentative hydrogen production [4,11]. The concept of such systems is the in-situ recovery and purification of biologically formed hydrogen from the fermenter off-gas -containing notable amount of CO 2 beyond H 2 -in a way that it may be directly utilized in fuel cells.…”

“…The concept of such systems is the in-situ recovery and purification of biologically formed hydrogen from the fermenter off-gas -containing notable amount of CO 2 beyond H 2 -in a way that it may be directly utilized in fuel cells. Moreover, the instant and continuous extraction of hydrogen helps to keep lowered hydrogen partial pressure in the reactor which has been proven advantageous for higher hydrogen production yields [11]. The separation of hydrogen from complex biological gas mixtures is a challenging task because several compounds, such as carbon dioxide, hydrogen sulfide, water vapor, etc.…”

“…pose a threat to achieve the required enrichment efficiency [4]. Recently, our group has tested a range of gas purification membranes made of different materials such as polyimide, SAPO 34 and silicone for fermentative hydrogen concentration, using binary (H 2 /CO 2 ) mixtures [11,12]. Regardless of the membrane module, it could be concluded that the composition of the feed gas is a key factor to be considered.…”

In this work the establishment of a double-membrane bioreactor was aimed. Initially, a continuous hydrogen fermenter was coupled with a commercial Kubota ® microfiltration membrane module and the production performance of the cell-retentive design was evaluated under various hydraulic retention times. As a result, it has been observed that altering HRT influenced the rejection feature of the microfiltration module while had an inverse effect on hydrogen productivity and yield, since shortened HRTs were accompanied by gradually decreasing H 2 yields (HY) and progressively increasing volumetric H 2 production rates (HPR). The highest HY and HPR were achieved as 1.13 mol H 2 /mol glucose and 0.24 mol H 2 /L-d, respectively. Furthermore, a Permselect ® (PDMS) gas separation membrane was installed to the anaerobic membrane bioreactor and its ability to separate hydrogen from the raw fermentation gaseous mixture was assessed. The highest purity hydrogen obtained in onestep purification by the PDMS module was 67.3 vol.%, which exceeds 30% enrichment efficiency considering 51.3 vol% H 2 in the feed gas. Hence, it could be concluded that the poly(dimethyl siloxane) membrane has potential to attractively concentrate biohydrogen from fermenter off-gas and may be used for in-situ product recovery.

a b s t r a c tThe start-up of continuous biohydrogen fermentations is a complex procedure and a key to acceptable hydrogen production performance and successful long-term operation. In this review article, the experiences gained and lessons learned from relevant literature studies dealing with various aspects of H 2 producing bioreactor start-up are comprehensively surveyed. Firstly, the importance of H 2 -forming biosystem start-up including its main steps is outlined. Afterwards, the role of main influencing factors and methods (e.g. strain selection, seed pretreatment and inocula stimulation, switch-over time, bioreactor design, operating conditions) in avoiding the deterioration of starting a reactor is analyzed and presented in detail. Finally, the so far suggested applicable start-up strategies and the corresponding findings are critically discussed pointing out the advantages and disadvantages of each strategy.

Feasibility study of polyetherimide membrane for enrichment of carbon dioxide from synthetic biohydrogen mixture and subsequent utilization scenario using microalgae

In this work, the potential of utilizing a polyetherimide (PEI) hollow-fiber membrane to separate synthetic biohydrogen mixture (H 2 /CO 2 ) was studied.From the gas separation experiments, where the effects of feed to permeate pressure ratio (P feed /P permeate ) and stage-cut as key factors were evaluated, it was found that the PEI membrane had the capacity to purify either H 2 or CO 2 .It turned out that different separation settings should be chosen in accordance with the actual technological purpose, defined either as the enrichment of H 2 or CO 2 . The highest H 2 concentration (66.4 vol%) in the permeate was achieved at P feed /P permeate of 4.62 and stage-cut of 0.47, while the peak CO 2 concentration (79.2 vol%) in the retentate was obtained by applying P feed /P permeate of 4.55 and stage-cut of 0.65. The assessment and discussion of results indicated the possible utilization of the CO 2 -rich fraction (produced by the PEI membrane) for the biological sequestration using microalgae. To our knowledge, PEI membranes have not yet been tested in such a concept and thus, the results and experiences can mean a new contribution to the literature.
