Nanofiltration separation is a new type of membrane separation technology, with a technical principle similar to mechanical screening. However, the nanofiltration membrane itself is charged. This is an important reason why it maintains high desalination performance even at very low pressures and can remove inorganic salts even when using membranes with a molecular weight cut-off of hundreds. Nanofiltration separation is increasingly used in the electronics, food, and beverage industries, such as ultra-pure water preparation, highly concentrated fruit juices, separation of peptides and amino acids, antibiotic concentration and purification, whey protein concentration, nanofiltration membranes-Bio-reactor coupling and other practical separation processes.Compared to ultrafiltration or reverse osmosis, the nanofiltration process is effective for single ions and molecules with a molecular weight less than200Poor retention of organic matter, but effective for divalent or multivalent ions and molecules with a molecular weight of200~500High removal rate of organic matter between. Due to these characteristics, the nanofiltration process is mainly used for water softening and purification, as well as for the separation, grading, and concentration of substances with a relative molecular weight up to hundreds (such as the grading and concentration of dyes, antibiotics, polypeptides, polysaccharides, etc. in chemical and biochemical engineering products), decolorization, and removal of odors. Mainly used for removing impurities from drinking water.Ca、MgIon hardness components, trihalomethanes, odor, color, synthetic detergents, soluble organic matter, and evaporative residue.
