Abstract：
 The invention is a method of enhancing operation performance of nano filtering and reverse osmosis course by magnetization pretreatment. It discloses the method for prohibiting the pollution problem in the course of nano filtering and reverse osmosis and enhancing film operation flux and retention, during the course of nano filtering and reverse osmosis, makes magnetization pretreatment on the water, the applied magnetic strength 100mT-500mT, the water flow speed in the magnetic field controlled at 0.5-3m/S and the temperature controlled at 13 deg.C-40 deg.C. It enhances both the film flux and the film retention to solute. At the same time, it will have no effect on water quality and personal safety, and has low energy consumption and some particular advantages.
