$1,892.00 Sale




4Dow® Filmtec™ NF90-4040 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. The low net driving pressure of the NF90 membrane allows the removal of these compounds at low operating pressures.

ADVANTAGES

  • Size: 4"X40"
  • Capacity: 1850 GPD Water production capacity
  • Rejection: 97.0% Stabilized salt rejection
  • Removes high percentage of salts, nitrate, iron TOC & THM precursors
  • High flux results in high yields
  • Medium to high salt passage & medium hardness passage
  • Low energy usage reduces power consumption and costs
  • Durable with good cleanability for long element life
  • Trouble-free treatment for a wide range of difficult freed water
  • FilmTec performance and quality
  • Made in USA with advanced technology by Dow Filmtec

APPLICATIONS

  • Production of drinking water
  • Demineralization in small commercial applications
  • Not recommended for sail boats and seawater desalination  (Use SW30-4040 with 1000 psi instead)

    TEST CONDITIONS:

    • Applied Pressure: 70 PSIG (0.48 MPa)
    • 77°F (25°C) Operating Temperature
    • 15% Permeate Recovery
