FILMTEC™ BW30-400/34i-FR

The FILMTEC BW30-400/34i-FR element is the ultimate element for durable, high rejection, high productivity performance to purify water with high biological or organic fouling tendency. With Dow's proprietary FR membrane technology that provides superior fouling resistance and cleanability, this product is an extension of the FILMTEC BW30-365-FR and BW30-400-FR elements that have demonstrated their value for numerous customers around the world since 1997.

The BW30-400/34i -FR element features:

  • A wide 34 mil feed spacer to lessen the impact of fouling and enhance cleaning effectiveness.
  • 400 square feet active area for more productivity without increasing the operating flux.
  • High rejection FILMTEC RO membrane that has the widest pH cleaning range in the industry (pH 1-13) that allows for effective cleaning of scale, organic compounds and biofilm.
  • Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.
  • iLEC™ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that compromise system integrity and cause poor water quality.

This unique combination of features offers system operators the best long-term economics and most trouble-free operation for RO membrane purification of fouling waters.

1. Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psi (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 +/-5%. Active area as stated by FilmTec is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (166KB PDF).
