40" × 8" Nanofiltration Element for Commercial Applications

The FILMTEC™ NF90-400 nanofiltration element is a high area, high productivity element designed to remove a high percentage of salts, nitrates, iron, and organic compounds such as pesticides, herbicides, and THM precursors.

The high active membrane area combined with the low net driving pressure of the membrane allows the removal of these compounds at low operating pressures.

Nominal Active Surface Area: 400 sq. ft. (37 m²)

  1. Permeate flow and salt passage based on the following test conditions:
    2000 mg/l NaCl, 70 psi (0.48 MPa), 77°C (25°C) and 15% recovery
    2000 mg/l MgSO4, 70 psi (0.48 MPa), 77°C (25°C) and 15% recovery
  2. Flow rates for individual elements may vary ±15%.
  3. The above specifications are benchmark values. Please be sure to operate according to our system design guidelines.
