Product Description

UltraClean UC NF90 series nanofiltration membrane elements can achieve high water production and have excellent removal performance of monovalent and divalent salts removal rates, such as pesticides, herbicides and THM precursors, etc., have high removal capacity for natural organic matter. In the process of water treatment, it can reduce the hardness of water, and can also effectively remove toxic and harmful substances in water, and remove turbidity, chromaticity and organic matter. In addition, high-priced salts and small-molecule organics with economic value can be recovered. It requires low net driving pressure, and can effectively remove impurities or recover useful substances under very low operating pressure. The system has low energy consumption and good economy. Suitable for papermaking, printing and dyeing industries and municipal water treatment systems.

 

Product Highlights

1.Excellent removal of monovalent and divalent salts
2.Suitable for removal of TOC and THM precursors
3.System for removing salts at ultra-low pressure with low operating energy consumption
