DOW RO Membrane BW30HR-440i

Model:BW30HR-440i
Price:0US$
The DOW™ FILMTEC™ BW30HR-440i element is a high-performing, high productivity element combining the highest active membrane area available in the industry today with the maximum rejection brackish water reverse osmosis (RO) membrane. It incorporates Dow's innovative BW30HR membrane sheet technology, designed to deliver the highest quality RO permeate. This is combined with the cleanability of a 28 mil feed spacer, to minimize capital expenses in high-purity industrial water applications, without increasing operating flux.

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