NF sodium filter (high desalting type, 4040, 8080)

Product Information

NF sodium filter (high desalting type, 4040, 8080)

NF series products are polypiperazine composite nanofiltration membrane elements with selective separation characteristics. It has a high removal rate for almost all bacteria, viruses, microorganisms, macromolecular organics, antibiotics, pesticides, pesticide residues and other small molecular organics, heavy metals and most divalent and above ions in water or solution, while retaining part of sodium , potassium, calcium, magnesium, metasilicic acid and other beneficial nutritional minerals and small molecular substances. It can be used for the preparation of direct drinking water, mineral water and softened water, partial desalination and decolorization of wastewater with high salt concentration and organic matter concentration, and separation and purification of some inorganic salts, organic matter and other materials. Nanofiltration series products have extremely low operating pressure, which can greatly save the operating cost of equipment or systems, and are widely used in drinking water, food and beverage, medicine, reclaimed water reuse, wastewater treatment and other industries.
