40" × 8" Nanofiltration Element for Commercial Applications

The FILMTEC™ NF200-400 nanofiltration element is a high area, high productivity element designed to remove a high percentage of TOC such as pesticides, herbicides, and THM precursors while having a medium to high salt passage; medium hardness passage.

The FILMTEC NF200-400 element is an ideal element for surface and ground water applications where good organic removal is desired with partial softening in order to maintain a minimum level of hardness for organoleptic properties and preservation of distribution networks.

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

  1. Permeate Water Flow:
    Permeate Flow Rate, gpd(m3/d) CaCl2: 8000 (30.3) Permeate Flow Rate, gpd(m3/d), for MgSO4: 6800 (25.7)
  2. Stabilized Salt Rejection:
    Stabilized Salt Rejection for CaCl2: 50 - 65%
    Stabilized Salt Rejection for MgSO4: 3%
    Stabilized Salt Rejection for Atrazine: 5%
  3. Permeate flow rate and salt rejection based on the following test conditions:
    500 mg/l CaCl2, 70 psi (0.48 MPa), 77°F (25°C), and 15% recovery.
    2000 ppm MgSO4, 70 psi (0.48 MPa), 77°F (25°C), and 15% recovery.
  4. Permeate flow rates for individual elements may vary ±15%.
  5. The above specifications are benchmark values. Please be sure to operate according to our system design guidelines.
