FilmTec™ Nanofiltration 8" Elements


FilmTec™ NF270-440


FilmTec™ NF270-440 presents an ideal solution for utility managers and operators dealing with surface and groundwater and seeking a technology that removes a high percentage of total organic carbon (TOC) and trihalomethane (THM) precursors while having a medium to high salt passage and medium hardness passage.

Our latest NF innovation enables end-users to reduce CAPEX of nanofiltration systems and simplify the overall system design by offering a 10% more active membrane area. It also delivers 10% energy saving and improvement on biofouling resistance. 

Benefits of the FilmTec™ NF270-440 Element include:

  • Reduction in feed-side pressure drop by up to 50%, improving system energy efficiency and hydraulic balance*.
  • Fouling-resistant design, reducing the number of chemical cleanings by more than 20%*.

*Relative to a leading fouling-resistant product currently available in the market.
