Use of biomimetic forward osmosis membrane for trace organics removal

Open-source CFD model for optimization of forward osmosis and reverse osmosis membrane modules

“…Membrane parameters for A, B and K were estimated for the Aquaporin Inside Membrane TM (Aquaporin A/S, Denmark), which can be considered an example of a state-of-the-art commercial FO membrane, designed using a biomimetic approach [36,37]. The resulting parameters are listed in Table 1.…”

“…Membrane parameters were estimated from experiments with an Aquaporin Inside TM FO membrane, see [36,37], by using an approach similar to that described by Tiraferri et al [38]. Briefly, FO experiments were performed using the CF042 chamber at various draw concentrations, following the protocol described in [23]; the water and solute fluxes were calculated for each concentration, and then the data was fitted to Eq.…”

“…The cross-flow velocities were set at values between 2 and 512 mL/min, where the lowest cross-flows correspond to lower than normal experimental conditions. Cross-flows of $50 mL/min are common under experimental conditions where peristaltic lab-scale pumps are used [23,37], and $500 mL/min corresponds approximately to the experimental conditions obtained using gearing pumps [18]. The cross-flows used in this work represent Reynolds numbers between $1.5 (2 mL/min) and up to $450 (512 mL/min), corresponding to fluid velocities on the order of $10 À4 to 0.1 m/s, respectively.…”

Enhanced performance of a biomimetic membrane for Na2CO3 crystallization in the scenario of CO2 capture

“…In the biomimetic AIM 60 membrane, aquaporin proteins incorporated in the membrane structure can potentially facilitate gradient driven water diffusion in FO process [42]. In order to investigate how the membrane morphology is potentially affected by the crystallization process, the basic membrane morphology is characterized (see Figs.…”

Influences of mechanical pretreatment on the non-biological treatment of municipal wastewater by forward osmosis

“…Furthermore, Madsen et al [40] showed high rejections of trace organic compounds when using AIM membranes. These results imply high BOD rejections.…”
