WaterSolutions DOW FILMTEC BW30-400/34i


The DOW™ FILMTEC™ BW30-400/34i element is the ultimate element for durable, high-rejection, high-productivity performance in high fouling or challenging feed conditions, enabling trouble-free operation and low cost of water.

  • Features a 34 mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness.
  • Offers the proven performance and high productivity of the DOW FILMTEC BW30 membrane.
  • Delivers a lower total cost of water by enabling lower capital and/or operating expenses compared to 365 sq. ft. elements.
  • Includes iLEC™ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.

 

Nominal Active Surface Area
ft2 (m2)		 Permeate Flow Rate
gpd (m3/d)		 Typical Salt Rejection
(%)		 Minimum Salt Rejection
(%)
400 (37) 10,500 (40) 99.5 99.0
  1. Permeate flow rate 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% below the value shown.
  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).
