DuPont FilmTec Nanofiltration Elements

DOW FilmTec Reverse Osmosis Membranes
DOW FilmTec Nanofiltration NF Membrane Elements

DOW FILMTEC™ NF Elements, available in 2.5-inch and 4-inch diameters provide exceptionally high productivity while removing a high percentage of minerals and organic compounds with low energy usage and reduced power consumption and cost. DOW FilmTec nanofiltration elements are designed to remove a high percentage of TOC and THM precursors while having a medium to high salt passage and medium hardness passage.

  • DOW FILMTEC NF270 nanofiltration membrane elements are ideal for removing a high percentage of TOC and THM precursors with medium to high salt passage and medium hardness passage. The DOW FILMTEC NF270 membrane is an ideal choice for surface water and groundwater where good organic removal is desired with partial softening.
  • DOW FILMTEC NF90 nanofiltration 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.
