DOW™ FILMTEC™ BW30XFR-400/34i has an optimized design and materials of construction to create a durable, high rejection and high productivity element to purify waters with biological and organic fouling tendencies. Incorporating Dow's innovative and proprietary BW30XFR membrane sheet with advanced organic fouling resistance and cleanability, this reverse osmosis (RO) element combines the best features of fouling resistance and durability, with the cleanability of an optimized 34 mil feed spacer, to improve cleaning effectiveness. All this while delivering high element performance over the life of the spiral wound brackish water RO element.

  1. Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.5 bar), 77°F (25°C), pH 8 and 15% recovery.
  2. Flow rates for individual elements may vary, but will be no more than +/-15%.
  3. Sales specifications may vary as design revisions take place.
  4. Active area guaranteed +/-3%. 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).
  5. Typical solute stabilized rejections based on the following standard test conditions: 2,000 ppm NaCl, 225 psi (15.5 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.
