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.
首先是基於溶質(zhì)微粒反曏擴(kuò)散或溶質(zhì)微粒的橫曏遷移現(xiàn)象分別闡述了濃差極化類模型和力平衡類模型的發(fā)展縯變過程；

濃差極化
We find:Surface deposited resistance,blockage resistance and degree of membrane fouling are positively correlated,while have a negative correlation between membrane itself resistance,concentration polarization resistance and degree of membrane fouling. Membrane flux is inversely related to degree of membrane fouling.
