Abstract:

Based on the ideal structure model of RO membrane element, the differential equations model of the RO membrane element operation has been established. Based on analyzing the operation parameters of RO membrane element, the boundary conditions of the differential equations are confirmed. Thus, the differential equations have the unique solution. The establishment of differential equations model of the membrane element operation provides a mathematical basis for the programming of accurately simulating calculation software of the membrane element and membrane system.

Key words: RO membrane element, simulated software, mathematical model
