Dow Filmtec BW30-365 Reverse Osmosis (RO) Membrane
9,500 GPD industrial / commercial replacement reverse osmosis (RO) membrane element
For years, the Filmtec BW30-365 has been the element of choice for system designers, OEMs and system operators requiring consistently high performance and maximum element life when treating difficult feed waters. This element offers proven performance, high rejection and outstanding robustness and durability across a wide range of feed conditions where unit price is a key driver.
- Features the industry's thickest feed spacer (34 mil) to lessen the impact of fouling.
- May be cleaned over the widest pH range (pH 1-13) for the most effective cleaning.
- The BW30-365 is best suited for systems operating on challenging feed streams, where reliable pretreatment is not an option, or where maximum cleanability delivers value.

*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.
