FILMTEC™ BW30-400-FR
Designed to purity water with high biological or organic fouling potential in systems with well-controlled pretreatment, FILMTEC BW30-400-FR reverse osmosis elements incorporate Dow's proprietary FR membrane technology that provides superior fouling resistance and cleanability. This product is an extension of the FILMTEC BW30-365-FR element that has demonstrated its value for numberous customers around the world. The BW30-400-FR element features:
-
High active area (400 square feet) 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.
These features offer system operators the best long-term economics and most trouble-free operation for RO membrane purification of fouling water.

1. Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.3 bar), 77°F (25°C), pH 8, and 15% recovery.
2. Permeate flow rates for individual elements may vary but will be no more than 15% below the value shown.
3. For the purpose of improvement, specifications may be updated periodically.
4. Active area guaranteed +/-3%. 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.
