Product Description
UltraClean UC NF500 series nanofiltration membrane elements have the characteristics of extremely high flux, high salt rejection, high retention of divalent ions and good passing performance of monovalent ions, achieving high water production and moderate removal performance. , can effectively cut off molecular weight above 300~500D. Organic matter, with excellent decolorization performance. The element utilizes the latest element manufacturing techniques to minimize filter dead space and bypass. Suitable for reuse of reclaimed water, municipal water, etc. Available in 4" and 8" sizes.
Product Highlights
Excellent removal of salts
Suitable for removing TOC and THM precursors
Salt removal under ultra-low pressure and low energy consumption
