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 FILMTEC BW30-365 element is best suited for systems operating on challenging feed streams, where reliable pretreatment is not an option, or where maximum clean ability delivers value.
