Biological Engineering Membrane Separation Equipment, Nanofiltration Equipment,香菇多糖Separation and Extraction, Emerging Technology

Nanofiltration is a membrane separation technology that lies between ultrafiltration and reverse osmosis, with a molecular weight cut-off ranging fromIn the range of 200-1000 nm, the pore size is several nanometers. Since this membrane retains molecules larger than 1 nm with a higher than 95% rejection rate during the filtration process, it is called nanofiltration. Owing to the superior characteristics of nanofiltration separation technology, it has shown broad application prospects in many fields, such as scientific research units, biotechnology, and food industry. A significant feature of nanofiltration membranes is that the membrane itself is charged, which is an important reason for its high desalination performance under low pressure and the ability to remove inorganic salts from membranes with molecular weight cut-offs in the hundreds. We offer a variety of compact, rolled nanofiltration membrane elements with reasonable surface area/volume ratios. By employing different channel networks (13-120 mil), the width of the feed stream channel can be adjusted to accommodate various viscosities. To meet the needs of specific industries, we can select the appropriate nanofiltration membrane based on the customer's process requirements, the characteristics of the treatment system, and related technical specifications.
