SW30XHR-440i FilmTec DuPont / DOW Membranes

DuPont FilmTec SW30XHR-440i Seawater RO Membrane

The DuPont FilmTec SW30XHR-440i is the Extra High Rejection (XHR) Seawater Reverse Osmosis Element, specifically engineered to produce the highest quality permeate water available from a single-pass system. As the premium "High Rejection" model in the FilmTec lineup, it offers an industry-leading 99.82% stabilized salt rejection, making it the definitive choice for applications with stringent water quality standards, such as high-purity industrial processes or municipal drinking water where boron removal is critical.

This 8-inch diameter element features a massive 440 ft² active surface area, allowing for high productivity despite its tight rejection characteristics. It comes standard with iLEC™ (Interlocking End Caps) technology, a distinct coupling system that eliminates the need for sliding o-rings. This ensures a leak-tight mechanical seal between elements, preventing permeate contamination and significantly reducing maintenance requirements. The SW30XHR-440i is designed to withstand high-pressure operation while delivering exceptional durability and fouling resistance thanks to its 28-mil feed spacer.
