Performance Parameters & Strict Quality Assurance
As a high-efficiency, high-rejection BWRO membrane element, DuPont FilmTec™ BW30HRLE-440 boasts industry-leading performance parameters validated by rigorous quality control processes. It features a 440 ft² (41 m²) active membrane area, delivering a stable permeate flow rate of 12,000 gpd (45 m³/d) under standard test conditions (2,000 ppm NaCl, 225 psi/15.5 bar, 77°F/25°C, pH 8, 15% recovery). With a typical stabilized salt rejection of 99.7% and a minimum salt rejection of 99.5%, it efficiently retains dissolved salts, silica, and other impurities—critical for meeting strict industrial water purity standards [1][3]. Each element undergoes strict factory testing to ensure performance consistency, adhering to DuPont’s stringent quality benchmarks for global deployment.
