Porous Membrane Separation Pilot Plant, High-Efficiency Industrial Membrane Filtration and Extraction Equipment, Compact Structure

NF membrane separation is a new type of membrane separation technology, with a technical principle similar to that of mechanical screening. Nanofiltration is a membrane separation technology that falls between ultrafiltration and reverse osmosis, with a molecular weight cut-off ranging fromIn the range of 200-1000 nanometers, the membrane has a pore size of a few nanometers. Since this membrane retains molecules larger than about 1 nanometer during the filtration process with a retention rate greater than 95%, it is called nanofiltration. Owing to the superior characteristics of nanofiltration separation technology, it shows great application prospects in fields such as wastewater treatment, biochemical engineering, and food industry. One significant feature of nanofiltration membranes is their charged nature, which is a key reason for their high desalination performance at low pressure and the ability to remove inorganic salts from membranes with a molecular weight cut-off of hundreds. We offer a variety of compact, rolled nanofiltration membrane elements with a reasonable surface area/volume ratio. By employing different channel networks (13-120 mils), the width of the feed stream channel can be adjusted to accommodate various viscosities. To meet the requirements of specific 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.
