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.

Product Name	Nominal Active Surface Area ft² (m²)	Permeate Flow Rate gpd (m³/d)	Stabilized Salt Rejection (%)	Minimum Salt Rejection (%)
FILMTEC BW30-400-FR	400 (37)	10,500 (40)	99.5	99.0

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.

These membranes may be subject to drinking water application restrictions in some countries: please check the application status before use and sale.
