NF90-400/34i DuPont FilmTec™ 10,000 GPD at 70 PSI 8 x 40 inch Nanofiltration Membranes

DuPont FilmTec NF90-400/34i High Rejection Nanofiltration Membrane with iLEC (10,000 GPD)

The FilmTec NF90-400/34i is a high-performance 8-inch nanofiltration element engineered for large-scale municipal and industrial water treatment. It is specifically designed to deliver high-quality permeate while selectively removing contaminants such as salts, nitrates, iron, and organic compounds like pesticides and herbicides. Utilizing advanced polyamide thin-film composite technology, this membrane provides a high level of productivity at low operating pressures, making it an energy-efficient solution for water softening and demineralization.

A standout feature of the NF90-400/34i is the inclusion of iLEC™ interlocking end caps, which significantly reduce the risk of O-ring leaks that can compromise water quality. The element features a 34-mil feed spacer that provides enhanced fouling protection and improves the efficiency of cleaning cycles. With an active membrane area of 400 square feet, it delivers a substantial permeate flow rate of 10,000 gallons per day, ensuring reliable and cost-effective performance for utility managers and system operators.
