Nanofiltration membrane is a roll film specially prepared by organic materials. The raw material liquid would flow in the membrane under external pressure, and the micromolecule substances, water and monovalent salt, would pass though the membrane whereas the macromolecule substances would be blocked in order to achieve the concentration of the liquid.
