NF Series of nanofiltration membrane elements can achieve high permeate water and excellent desalination performance. Therefore, it is suitable for large-scale industrial and municipal water treatment systems. In use, it shows an excellent ability to remove pesticides, viruses, and bacteria. It has a high ability to remove natural organic substances and a medium ability to remove total hardness. Through innovative technology, the product has a stronger film surface, and strong anti-oxidation performance, and the use of an ultralow pressure mode of operation can significantly improve the system and operation economy.
