Dow Filmtec NF90-2540 Nanofiltration Commercial Membrane - 2.5

Dow Filmtec NF90-2540 Nanofiltration Commercial Membrane - 2.5"X40", 680 GPD, 97% Salt Rejection

Regular price $369.57 Sale



DOW FILMTEC™ Membrane NF90 Nanofiltration (NF) Elements for Commercial Application.

Nanofiltration < 4" Elements allow selective separation of organics and salts for small industrial water treatment plants that produce less than approximately 1 gpm (230 L/h) of permeate.

Nanofiltration is a separation process characterized by organic, thin-film composite membranes with a pore size range of 0.1 to 10nm. Unlike reverse osmosis (RO) membranes, which reject all solutes, NF membranes can operate at lower pressures and offer selective solute rejection based on both size and charge.

ADVANTAGES

  • 680 GPD Water production capacity
  • 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 municipal drinking water
  • Commercial water demineralization
  • Water reuse
  • Surface water
  • Groundwater

The DOW FILMTEC NF90 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.
