摘要：

In order to study the problem of concentration polarization in seawater diluting reverse osmosis, this article has built a new reverse osmosis LBM model, which can more conveniently solve the unstable calculation of the diffusion coefficient, and compare it with the published documents accuracy. Based on this model, the phenomenon of reverse osmosis polarization of different Renault and different cross-membrane pressure differences is simulated. The results show that increasing the number of Renault can reduce the phenomenon of polarization and increase the amount of permeability of the membrane; while increasing the cross-membrane pressure difference and increased the polarization, it also increases the infiltration flux. Therefore, in practical applications, the size of the number of Re and cross-membrane pressure differences are needed. © 2024 Science Press. All rights reserved.
