DuPont FilmTec™ BW30-PRO-2540 Brackish-Water RO Membrane Element
The DuPont FilmTec™ BW30-PRO-2540 is a fiberglassed, spiral-wound RO element built on DuPont’s industry-standard BW30 brackish-water membrane — decades of proven performance, now with higher rejection and flow than the previous generation. Its rugged fiberglass outer shell delivers outstanding durability and enhanced fouling protection for challenging and variable feed-water conditions.
Rated for 1,000 GPD (3.8 m³/day) at an industry-leading 99.7% stabilized salt rejection, the BW30-PRO-2540 is the right choice when permeate quality and membrane durability matter most. Built on a polyamide thin-film composite membrane, it fits any standard nominal 2.5-inch I.D. pressure vessel.

Frequently Asked Questions
What is the DuPont FilmTec BW30-PRO-2540?
It is a 2.5" × 40" brackish-water reverse osmosis membrane element from DuPont Water Solutions. It produces up to 1,000 GPD at 99.7% salt rejection and features a fiberglassed hard-shell build for durability in harsh, high-TDS feed water.
How many gallons per day (GPD) does it produce?
Up to 1,000 GPD (3.8 m³/day) at DuPont’s standard test conditions (2,000 ppm NaCl, 225 psi, 77°F, pH 8, 15% recovery).
What salt rejection does the BW30-PRO-2540 achieve?
99.7% stabilized salt rejection, with a minimum of 99.5% — among the highest in its class.
Does the BW30-PRO-2540 replace the older FilmTec BW30-2540?
Yes. “BW30 PRO” is DuPont’s current designation for this 2540 element and is a direct, drop-in replacement for the FilmTec BW30-2540.
What pressure vessel does it fit?
Any nominal 2.5-inch I.D. RO pressure vessel. Multiple elements are joined with FilmTec™ coupler part number 89055, which is ordered separately.
What is the price of the BW30-PRO-2540?
ForeverPure lists this element at $239.00 each. Contact us at 408-969-2688 for volume and OEM pricing.
How do the XLE-PRO, BW30-PRO and TW30-PRO 2540 elements differ?
All three are 2.5"×40" FilmTec elements producing 1,000 GPD. The XLE (extra-low-energy) runs at the lowest feed pressure (125 psi) for energy savings; the BW30 (fiberglassed) is built for brackish and harsh feed water at the highest rejection; the TW30 (tape-wrapped) is the economical choice for standard tap and municipal water. BW30 and TW30 deliver 99.7% rejection; XLE delivers 99.0% at much lower energy.

Frequently Asked Questions: BW30-2540 vs. BW30 PRO-2540
What happened to the FilmTec BW30-2540?
DuPont discontinued the original FilmTec BW30-2540 and replaced it with the FilmTec BW30 PRO-2540, its official direct successor. It drops into the same 2540 housings with no system modifications.
What is the difference between the BW30-2540 and the BW30 PRO-2540?
- Current vs. discontinued: the BW30 PRO-2540 is the element DuPont manufactures today; the BW30-2540 is no longer produced. Remaining “BW30-2540” stock on the market is new-old-stock that may have been warehoused for years.
- Performance: Higher stabilized salt rejection: 99.7% for the PRO vs. 99.5% for the original BW30-2540. The PRO is rated 1,000 GPD at its test conditions (2,000 ppm NaCl, 225 psig, pH 8); the original was rated 850 GPD at a lower 150 psig test pressure, so flow figures are measured under different conditions.
- Newer manufacturing platform: the PRO series is built on DuPont's current precision, automated fabrication line, delivering tighter element-to-element consistency than the legacy process.
- Dry-shipped element: the BW30 PRO-2540 ships as a dry element — long shelf life and quick performance stabilization at start-up.
What is the same on both elements?
- Form factor: standard 2540 size (40″ length, 0.75″ permeate tube), tape-wrapped construction — fully interchangeable in standard 2540 pressure vessels with no system modifications.
- Rated performance basis: Both share the 28 ft²-class active area of the 2540 format and the 2,000 ppm NaCl test feed.
- Membrane chemistry: polyamide thin-film composite (TFC).
- Operating limits: 600 psig maximum operating pressure, 113 °F (45 °C) maximum temperature, feed SDI ≤ 5, free chlorine < 0.1 ppm.
Can I replace my BW30-2540 with a BW30 PRO-2540 without changing my system?
Yes. The BW30 PRO-2540 is a drop-in replacement for the BW30-2540 — same dimensions, connections, and vessel fit. No re-plumbing, housing change, or pump adjustment is required for a standard installation.
Which applications is the BW30 PRO-2540 designed for?
Brackish and well water in small commercial RO systems (under ~1 gpm): well water treatment and small high-rejection installations.
