n High Rejection Rate (over 98%):Provides high monovalent-divalent ion selectivity, enabling the production of high-purity salt solutions while reducing the liquid volume for down stream thermal treatment.
n Anti-fouling and Chemical Resistant: Expertly designed membrane chemistry ensures a reliable and robust element lifetime with outstanding anti-fouling properties.
n Higher Flux: Produces up to twice of flux compared to traditional TFC membranes, allowing increased water and resource recovery and/or reduced energy consumption.
n High Removal of Organic Compounds: High removal rate of Organic compounds such as pesticides, herbicides, antibiotics and THM precursors, etc.

From different standpoint and application scenario, there are different opinions on whether nanofiltration is a loose reverse osmosis.
The performance of NF98 series nanofiltration membrane directly replaces or even exceeds that of the mainstream imported membrane products, which can not only meet the Dunan effect with high selective retention of ions (FlG.4), but also desalting and COD removal performance can be differentiated accordina to the actual needs of customers. (Detailed cases and membrane products are welcome to consut senior pre-sales engineers).
