WaterSolutions DOW FILMTEC HRLE-440i

Featuring breakthrough membrane chemistry, the DOW™ FILMTEC™ HRLE-440i element delivers the same 99.5% nominal NaCl rejection as traditional brackish water elements but at 33% lower pressures.

Nominal Active Surface Area ft² (m²)	Permeate Flow Rate gpd (m³/d)	Stabilized Salt Rejection (%)	Minimum Salt Rejection (%)
440 (41)	12,650 (48)	99.5	99.3

Permeate flow and salt (NaCl) rejection based on the following standard conditions: 2000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8 and 15% recovery.
Flow rates for individual elements may vary, but will be no more than 15% below the value shown.
Sales specifications may vary as design revisions take place.
Active area guaranteed +/-3%. Active area as stated by Dow Water & Process Solutions is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
Specific solute typical rejections based on the following standard test conditions: 2000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 7 and 15% recovery, 50 ppm SiO₂, 5 ppm B, 100 ppm NO₃^-, 100 ppm NH₄⁺, or 100 ppm IPA.
