Product Description

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.
