Abstract:
Based on the ideal structure of flat ultrafiltration membrane element and balance equation of transmission process,the mathematical model of differential equation for ultrafiltration membrane element running has been established. The boundary conditions of the differential equation is confirmed by analyzing the operating parameters of the component,so as to confirm that the differential equation has the unique solution. The establishment of membrane element differential equation model provides a theoretical foundation for the structure and operation analysis of ultrafiltration membrane elements and a mathematical foundation for programming simulated software for ultrafiltration membrane system running.
