W-NF Series

W-NF series membrane element

8-inch NF membrane element

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 excellent ability to remove pesticides, viruses and bacteria. It has high ability to remove natural organic substances and medium ability to remove total hardness. Through innovative technology, the product has a stronger film surface, strong anti-oxidation performance, and the use of ultralow pressure mode of operation can significantly improve the system and operation economy.
