A novel methodology in design and simulation of membrane-based purification of organic solvents is proposed. A solution of water and alcohol served as model feed. Mass transfer and momentum transfer equations were derived and solved numerically to obtain the process output as function of process parameters. Water was taken as penetrant throughout the simulations. The studied process was pervaporation in which a nonporous polymeric membrane is used for purification of ethanol. Feed inlet concentration and velocity were considered as process input, water outlet concentration and removal efficiency as output. The Maxwell-Stefan mass transfer approach was applied for estimation of diffusion, the finite element approach for numerical simulation of the process. A lower feed velocity increased the water removal efficiency.

“…To minimize the amount of metals released into the environment, the development of selective solidphase sorbents is an essential pursuit for industrial applications and environmental remediation (2). Polymeric membranes are more effective, environmental friendly and energy saving technique in separation technology (3)(4)(5)(6)(7)(8)(9)(10)(11). Various types of polymeric membranes have been developed for gas and liquid separation (12-24).…”

Background & Aims of the Study: In this study, Metal Organic Frameworks (MOFs) were synthesized as an additive for the preparation of mixed-matrix membranes. MOFs were investigated by FTIR, XRD and FE-SEM techniques. Materials & Methods: Synthesized MOFs were prepared via the hydrothermal method. The effect of MOFs on the morphology and property of the polyethersulfone (PES) membranes was examined using scanning electron microscopy (FE-SEM). The membranes were characterized by rejection of salt solutions, removal of heavy metals and dyes rejection. Results: Results show that membrane containing 5 wt% of MOFs provides better hydrophilicity, flux, antifouling and rejection properties and change on the aforementioned characteristic properties was studied for this membrane. The results suggested that the water flux of membrane increased to 190 L.m-2 h-1 which related to 7 wt% membrane as well as the highest rejection for different heavy metals and dyes were related to 5 wt% MOFs in mixed matrix membranes. Conclusion:Based on the results, hydrophilicity, water flux, and antifouling properties were improved by hybrid membranes.
