Product Introduction:
The NF 90 series is a new type of nanofiltration membrane developed by Rixin Hengli. It is an efficient water treatment technology that is particularly suitable for removing organic compounds such as salt, nitrate, iron, insecticides, herbicides, and THM precursors from water. It is renowned for its high effective membrane area and low net driving pressure, enabling efficient removal of impurities at lower operating pressures. The NF 90 membrane exhibits high permeability for monovalent ions and high retention for divalent ions, demonstrating good ion selectivity. In addition, NF 90 membrane has a wide pH cleaning range and high chemical stability, making it suitable for softening treatment of various water systems and separation of large molecules in complex feed solutions.
Product advantages:
Having ultra-high throughput
Highly remove TOC and THM (trihalomethanes) precursors
