💧 DuPont FilmTec™ NF90-2540 Nanofiltration Element
Product Description
The DuPont FilmTec™ NF90-2540 is a premier 2.5-inch diameter Nanofiltration element engineered for applications that require high rejection of dissolved organic compounds and specific divalent ions, such as calcium and magnesium, while maintaining a moderate removal of monovalent salts. This element is ideal for softening applications, the removal of specific contaminants, and general water treatment where the goal is lower total dissolved solids (TDS) without the energy cost associated with full RO. It features a high active area and is designed for low operating pressure, making it an energy-efficient choice for commercial and light industrial systems. The NF90-2540 provides a nominal flow rate of 1,000 GPD at a low test pressure of just 70 PSI and offers a stabilized salt rejection of .
