The equations of solute rejection and concentrate rate on porous membrane were deduced based on the model of absorption-diffusion.Genetic algorithm (GA) was used to simulate the performance of the membrane.The calculated parameters
such as the solute distribution coefficient
the solute diffusion coefficient and the solvent diffusion coefficient in the membrane phase for the ESPA2 membrane
were all in agreement with the measured ones of aromatic polyamide reverse osmosis composite membrane and the mean square deviation of NaCl-permeability was between 10-7 and 10-6.
