BW30 PRO-400 DuPont FilmTec™ 11,000 GPD at 225 PSI 8 x 40 inch 99.6% Rejection Membranes

DuPont FilmTec BW30 PRO-400 Brackish Water RO Membrane (11,000 GPD)

The DuPont FilmTec BW30 PRO-400 is an industry-standard 8-inch brackish water Reverse Osmosis (RO) element, representing the evolution of the classic BW30 series. Designed for large-scale industrial and municipal water treatment, the PRO-400 delivers high performance and robust durability for challenging feedwaters.

This high-rejection element provides a superior stabilized salt rejection of $99.6\%$ and a nominal flow rate of $11,000\text{ GPD}$ when tested at $225\text{ PSI}$. The BW30 PRO-400 is constructed with a wide cleaning pH range tolerance (pH 1–13), giving operators maximum flexibility and confidence in cleaning procedures to maximize element longevity.

A key feature of the modern PRO series is the incorporation of the iLEC™ interlocking end caps (optional), which streamline element loading, reduce potential for O-ring leaks, and ultimately reduce operating costs and system downtime. The BW30 PRO-400 is ideal for plant managers seeking reliable, consistent water quality with the durability and performance trusted from decades of FilmTec development.
