| Abstract: | The existing micro-filtration flux models are described in three sections.Firstly, the development of the concentration polarization model or the force balance model is reviewed based on the back-diffusion and lateral migration of particles changing with process parameters.Secondly, the blocking mechanisms, the Darcy’s law and their development are introduced based on the adsorption of particles in membrane pore or the characteristics of deposition of particles on membrane surface.Thirdly, the combined model which takes into account the interaction of different factors is reviewed.Meantime, the potential future directions of predicting micro-filtration membrane flux model are discussed. |
