Dow Filmtec BW30-400 Reverse Osmosis (RO) Membrane
10,500 GPD industrial / commercial replacement reverse osmosis (RO) membrane element
The Filmtec BW30-400 is the product of choice when the highest quality permeate is required. It was the first 400 square foot membrane element on the market and continues to be widely used in new equipment and retrofits where system capital and productivity are factors.
- Filmtec's superior automated manufacturing technology results in the most consistent performance element-to-element and year-after-year.
- BW30-400 elements deliver high flow and high rejection without being chlorinated during the manufacturing process. This is one reason why Filmtec elements are more durable and may be cleaned over a wider pH range (pH 1-13) than other RO elements.
- With more than a decade of proven performance, BW30-400 is the product you can rely on for years of trouble-free operation.

*Permeate flow and salt rejection based on the following standard conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77F (25C), pH 8 and 15% recovery. Flow rates for individual elements may vary but will be no more than 7% below the value shown.
**Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow recommends removing residual free chlorine by pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.
***Maximum temperature for continuous operation above pH 10 is 95F (35C).
Note: Active surface area guaranteed +/-3%. Active area as stated by Filmtec is not comparable to nominal membrane area often stated by some manufacturers.
