Permeate flux prediction by integral osmotic-pressure model for ultrafiltration of macromolecular solutions

摘要

A novel and precise model has been proposed to predict the permeate flux for the ultrafiltration of macromolecular solutions, The pressure declination in the membrane module and a diffusion coefficient of concentration dependence are considered for the derivation of this model. The fluxes of permeate calculated by this model show a better agreement with the experimental data than those calculated by the model in previous work. [References: 13]
