Nanofiltration is a membrane separation technology that falls between ultrafiltration and reverse osmosis, with a molecular weight cut-off ofWithin the range of 200-1000 nm, the membrane has a pore size of a few nanometers. Since this membrane retains molecules larger than 1 nm with a higher than 95% recovery rate during the permeation process, it is called nanofiltration. Thanks to the superior characteristics of nanofiltration separation technology, it shows great application prospects in many fields such as electronics, bioprocessing, and food industry. A significant feature of nanofiltration membranes is their charged nature, which is a major reason for their high desalination performance under low pressure and the ability to remove inorganic salts from membranes with molecular weight cut-offs of hundreds. We offer a variety of rolled nanofiltration membrane elements with fine molecular weight cut-offs, featuring compact structure and a reasonable surface area/volume ratio. By employing different channel meshes (13-120 mil), the width of the feed fluid channel can be adjusted to accommodate fluids of various viscosities. To meet the requirements of certain special industries, we can select the appropriate nanofiltration membrane based on the customer's process requirements, the characteristics of the treatment system, and relevant technical specifications.
