DuPont FILMTEC™ BW30 PRO-2540 Brackish Water Reverse Osmosis Membrane Element (Direct Replacement for DOW FilmTec BW30-2540) FILMTEC BW30 PRO-2540 Elements are an industry standard for reliable operation and production of high quality water. They are designed for systems smaller than 1 gpm (0.2 m3/h). DuPont FilmTec(Formerly DOW FILMTEC) BW30 PRO-2540 elements offer a hard shell exterior for extra strength and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning. FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations. FILMTEC BW30 PRO-2540 is the direct replacement for FilmTec 
DOW FilmTec vs DuPont FilmTec & Membrane Compatibility Notes: - DowDuPont merger was completed in 2017 and FilmTec Corporation was moved to DuPont. DOW Water Solutions and DOW FilmTec Membranes are now DuPont Water Solutions and DuPont FilmTec Membranes.
- FilmTecMembranes BW30-2540 has been discontinued by DuPont in 2022 and is replaced by FilmTec BW30 PRO-2540 which is the direct replacement with superior performance specifications.
