In the preparation process of UltraClean UC NF150 series nanofiltration membrane elements, a unique formula and process are used. It is specially developed and produced for the special solute concentration and separation process, with stable and reliable performance and strong anti-pollution. It fills the blank range of molecular weight cutoff of existing nanofiltration membranes. It is suitable for separation of fine materials, removal of TOC and THM precursors, salt separation of monovalent and multivalent ions, decolorization, separation and concentration of small molecular organics, etc.
Advanced membrane technology with innovative thin layer composite membrane design.
More consistent performance with less fouling requiring less frequent cleaning and change-outs.
100% dry-stored membrane maximizing shelf life.

Permeate flow for individual elements may vary ±15 percent from the value specifed.
Active membrane area guaranteed ±4%.
Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
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.
