Abstract

The influence of pore wall surface property on the flux of a novel cylindrical-shaped nanoporous filtering membrane is analytically studied by using the flow factor approach model for a nanoscale flow. Across the thickness of the membrane are manufactured two concentric cylindrical pores with different radii. The smaller nanoscale pore is for filtration, while the other larger pore is for reducing the flow resistance. It was found that when the larger pore wall surface is hydrophobic, the interaction between the filtered liquid and the smaller pore wall surface has a very significant effect on the value of the optimum ratio of the radii of these two pores which yields the smallest flow resistance and thus the highest flux of the membrane; In the optimum working condition, the smaller pore wall surface property greatly influences the flow resistance of the membrane. It was found to be possible to manufacture the membrane with specific pore wall surface property used for filtering one liquid out of other liquids; In this membrane, the pore wall surface should be hydrophobic to the filtered liquid, while it should be highly hydrophilic to the other liquids.
