Nanofiltration (NF) is a membrane separation technology between ultrafiltration and reverse osmosis. It can intercept molecular weight in the range of 80-1000 and has a pore size of several nanometers, so it is called nanofiltration.
Based on the excellent characteristics of nf separation technology, it shows a broad application prospect in many fields such as pharmacy, bio-chemical industry and food industry.
Membrane separation technology is known as "water treatment technology in the 21st century". Since it was applied in the water treatment field in the 1970s, it has been widely studied and developed unprecedentedly. It has been widely concerned by water treatment workers in the world and has been carried out at different levels.
Different levels of theoretical research and technology development, application.
Most widely used in the field of water supply treatment is a series of low pressure membranes, such as nanofiltration membranes and reverse osmosis membranes.
Among them, nf water treatment technology, with its special advantages, has been widely concerned by water treatment workers in the world, and has made great achievements in the research and development of water treatment technology.
