Abstract
In order to estimate the effects of fouling layer and osmotic pressure on the performance of membrane separation system quantitatively, the concentration polarization equation and the membrane transport equation based on nonequilibrium thermodynamics are applied to membrane processes for liquid foods, and new mathematical models are proposed. The efficiency of the membrane processes could be expressed by the new models precisely. By using these models, some membrane processes for food industry are optimized and their feasibility evaluation is described.
