Mathematical Modeling and Numerical Simulation of Fouling Processes of Polymeric Ultrafiltration Membrane
Based on the fouling mechanism of polymeric ultrafiltration membrane, the mathematical model to describe the fouling process of polymeric surface active layer is established according to resistance equation, Darcy’s law, convection-diffusion equation and dynamic adsorption equation. The effect of solution concentration on permeating flux is investigated by means of finite element simulation, and the validity of the research approach is verified. The reasons why the flow flux declines are analyzed quantitatively, which gives a vivid description of the fouling process.
