FILMTEC™ NF90-400

The DOW 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.

Used in:

  • Industrial water demineralization
  • Production of drinking water
  • water reuse

Advantages:

  • High flux results in high yields, good rejection results in excellent water quality
  • Low energy usage reduces power consumption and costs
  • durable with good cleanability for long element life
  • Filmtec Performance and quality
