Theory and method of application-oriented ceramic membranes design (II) Prediction of effects of membrane structure parameters on microfiltration of particle suspension

Based on the established model of microfiltration for separating particle suspensions, which described the relation between membrane structure parameters and its permeability, the influences of membrane structure parameters such as pore size, thickness and porosity on its performance were theoretically predicted and discussed under the ideal conditions that membrane pore size and particle size distribution are normal. The simulated results showed that there was an optimum pore size in the filtration of suspensions which maximized permeate flux, and the optimum pore size was influenced by the size and size distribution of the particulates.
