Applied Membranes Inc. Membrane Elements Water Treatment RO UF NF
4" x 40"  Nanofiltration Membrane | NF9 - 90% Salt Rejection | 97% Hardness Rejection

Applied Membranes NF9 spiral wound nanofiltration elements provide high productivity performance while removing a high percentage of salts, nitrate, iron and organic compounds such as pesticides, herbicides and THM precursors. The low net driving pressure of the NF9 membrane allows the removal of these compounds at low operating pressures.

AMI NF Membranes are Made in the USA in their ISO 9001:2015 Certified Facility and are 100% Quality and Performance Tested.
