Experimental verification of the shear-induced hydrodynamic diffusion model of crossflow microfiltration, with consideration of the transmembrane pressure axial variation

摘要

A model based on the shear-induced hydrodynamic diffusion theory, with the consideration of the axial variation of the transmembrane pressure drop, was developed for a hollow fiber crossflow microfiltration module. The model predictions agreed closely with experimental data obtained for a commercial hollow fiber microfiltration module used for a monodisperse latex particle suspension forming a stagnant particle layer at the membrane surface.
