FILMTEC™ SW30XLE-440i

DOW™ FILMTEC™ SW30XLE-440i offers medium salinity and medium temperature feed waters an advanced combination of high productivity and high rejection through extra-low energy consumption and single-pass design. It is also an ideal choice for two-pass seawater designs or high salinity brackish water applications. The combination of highest active area and thickest feed spacer of the Dow FILMTEC membranes results in higher productivity and lower cleaning frequency which enable sustainable lower lifecycle cost.

  1. 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.
  2. Permeate flows for individual elements may vary +/-15%.
  3. Product specifications may vary slightly as improvements are implemented.
  4. 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.
