BACKGROUND Pervaporation performance in a PDMS membrane bioreactor for ethanol recovery from model solution and fermentation broth was researched. Downstream of the membrane the permeate vapor was completely condensed by running water and air at room temperature. RESULTS Part of the permeate vapor was condensed under vacuum conditions by running water at room temperature in condenser C1, with ethanol concentration of 47.2 g L−1 obtained. The vacuum pump in the pervaporation membrane bioreactor was used to compress and pump the non‐condensed permeate vapor with ethanol concentration of 461.3 g L−1 into the condenser C2, where the vapor could be easily condensed under atmospheric conditions by air at room temperature. During the experimental ethanol recovery from model solution the total flux and separation factor were about 1100 g m−2 h−1 and 8.0, respectively, while the permeate flux of the membrane was reduced during the separation of fermentation broth. CONCLUSION Compared with a traditional pervaporation process, the cold trap condensation was eliminated in the process and enhanced ethanol fermentation was achieved since pervaporation was continuously coupled with fermentation. © 2016 Society of Chemical Industry

“…During the early 72 h of the process, the broth pH was kept in 4.0 ± 0.5 and then gradually increased to 6.5 so as to relieve the inhibition of the organic acids accumulated in the broth. The detailed procedure of the CCCF process with the pervaporation membrane bioreactor had been fully described in our previous work (Fan et al, 2014b). The first run of fermentation was terminated when the viable cell ratio decreased to about 8% and the average ethanol productivity was about 0.85 g L À1 h À1 during final 12 h. The second experiment was terminated when the viable cell ratio was about 5% and the average ethanol productivity was about 0.56 g L À1 h À1 during final 12 h.…”

“…In the recent experimental evidences, owing to the improvements for the permeate vapor condensation and recovery at the membrane downstream in CCCF process, the pervaporation separation and fermentation for ethanol were continuously coupled, so that the CCCF process was brought about a steady state and its time course profiles became relatively smooth. These recent experiments have also revealed more process features of the CCCF process, directing us to the more comprehensive acquaintance with the process (Fan et al, 2014b). Among those features, the accumulated secondary metabolites in the broth and the cell death along with the fermentation have become two focuses of the CCCF process (Chen et al, 2012;Fan et al, 2014a).…”

Pervaporation is a process that employs dense membrane to separates liquid mixtures. Various types of membranes: polymeric, ceramic, or composite can be used. In recent years there has been significant academic as well as industrial advancement in this attractive membrane process. Novel types of membranes have been reported. These include nanocomposite including nano‐sized metal, metal oxide, and graphene/graphene oxide incorporated ceramic/polymer membranes, polyamine‐based thin film composite membranes (earlier commercialized for reverse osmosis membranes), copolymer/interpenetrating network types membranes, template type membranes, polyelectrolyte complex, gold and silver nanoparticle‐based membranes for plasmon PV, and so on. In the application area, besides the well‐known alcohol dehydration PV has been investigated for recovery of aroma and flavor in the food and beverage industries, desulfurization of gasoline, intensification of chemical reactions, and so on. Further, PV is being extensively used as a low‐temperature environment friendly “green technology” for safe removal of volatile organic compounds using highly selective organophilic membranes. The advent of metal–organic framework membranes has resulted in significantly higher selectivities as compared to conventional membranes. PV is also being investigated for desalination with hydrophilic membranes. This article provides a state of the art discussion on PV that includes basic principles, types of membranes/modules, and important industrial applications.
