UltraClean UC NF90 series NF membranes provide high flux and excellent performance of removing monovalent and divalent salts. It also has high removal rate of organic compounds, such as pesticides, herbicides and THM precursor, etc.
It also has high removal of natural organic compounds. In the water treatment process, it can not only reduce the hardness of the water, but also effectively remove the toxic and harmful substances in the water, remove turbidity, color and organic matter. In addition, it can also recover valuable multi-valent salts and small molecular organics. It requires low net driving pressure, and can effectively remove impurities or recover useful substances under very low operating pressure. The system runs with low energy consumption and cost. It is suitable for papermaking, printing and dyeing industry and municipal water treatment system.
Excellent removal of salts
Suitable for removing TOC and THM precursors
Salt removal under ultra-low pressure and low energy consumption

It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard.
The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation.
Keep elements moist at all times after initial wetting.
To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.
The membrane shows some resistance to short-term attack by chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.
