FILMTEC™ SW30HR LE-440i
The DOW™ FILMTEC™ SW30HRLE-440i element offers sustainable lower lifecycle cost for medium and high salinity feedwaters by combining high rejection and low energy performance with the highest active area and thickest feed spacer of the Dow membranes.

The above values are normalized to the following conditions: 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8 and 8% recovery.
- Permeate flows for individual elements may vary +/-15%.
- Product specifications may vary slightly as improvements are implemented.
- Active area guaranteed +/-5%. Active area as stated by Dow Water & Process Solutions is not comparable to the nominal membrane area figure often stated by some element suppliers. Measurement method described in Form No. 609-00434.
