The FilmTec NF90 Membrane 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 NF90 membrane allows the removal of these compounds at low operating pressures.
Applied Pressure – 70 psig (4.8 bar)
Permeate Flow Rate – 2,00 gpd (7.6 m3/d)
Minimum Salt Rejection – 98.7%
