WaterSolutions DOW FILMTEC SW30HRLE-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 high active area and thick feed spacer of the Dow membranes.

Nominal Active Surface Area ft² (m²)	Permeate Flow Rate gpd (m³/d)	Stabilized Boron Rejection (%)	Stabilized Salt Rejection (%)	Minimum Salt Rejection (%)
440 (41)	8,200 (31)	92	99.80	99.65

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 is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
