Membrane biofilm reactors are a growing trend in wastewater treatment whereby gas-transfer membranes provide efficient bubbleless aeration. Recently, there has been a growing interest in using these bioreactors for industrial biotechnology using microorganisms that can metabolise gaseous substrates. Since gas fermentation is limited by the low solu...

... 24 h intervals, the OTR was measured at both the normal (steady state) intramembrane pressure (200 mbar) and also at a range of elevated intramembrane pressures (ranging from 120 to 450 mbar). Figure 9 shows the effect of intramembrane pressure on OTR corresponding to a range of different biofilm thicknesses as the experiment progressed. OTR increases linearly as intramembrane pressure increases, which is not unexpected as the driving force for oxygen transfer increases. ...
