NF nanofiltration membrane tube (ultra-high water capacity type, 4040, 8040) (applicable to: mineral water, water filling station)
NF series products are polypiperazine composite nanofiltration membrane tube elements with selective separation characteristics. It has a high removal rate for almost all bacteria, viruses, microorganisms, macromolecular organic substances, antibiotics, pesticides, pesticide residues and other small molecular organic substances, heavy metals and most divalent and above ions in water or solution, while retaining part of the sodium , Potassium, calcium, magnesium, metasilicate and other beneficial nutritional minerals and small molecular substances. It can be used for the preparation of direct drinking water, mineral water, softened water, partial desalination and decolorization of waste water with high salt concentration and organic matter concentration, and separation and purification of some inorganic salts, organic matter and other materials. The operating pressure of nanofiltration series products is extremely low, which can greatly save the operating cost of equipment or systems, and is widely used in drinking water, food and beverage, medicine, reclaimed water reuse, wastewater treatment and other industries.
