FilmTec™ NF90-4040

(Suggested alternatives: Hydranautics ESNA1-LF-LD-4040, FILMTEC NF270-4040, Hydranautics ESNA1-LF2-LD-4040)

FilmTec™ NF90-4040 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 NF90 membrane allows the removal of these compounds at low operating pressures.


FilmTec™ Nanofiltration 4" Elements allow selective separation of organics and salts for medium-sized industrial and municipal water treatment plants that produce less than approximately 10 gpm (2300 L/h) of permeate.
