FILMTEC™ SW30XHR-440i

The DOW™ FILMTEC™ SW30XHR-440i element is the highest rejection seawater RO element in the DOW FILMTEC element portfolio, enabling stringent water quality requirements to be met reliably with single pass seawater systems in most situations. In addition, the combination of highest active area and thickest feed spacer 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, 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.
