Executive Product Summary
The FilmTec™ BW30HRLE-440 is an advanced, high-performance brackish water reverse osmosis (RO) element engineered by DuPont for demanding industrial and municipal water treatment applications. Fabricated utilizing a state-of-the-art automated manufacturing process, this 8-inch diameter element features a highly durable polyamide thin-film composite membrane. This precision material science allows the BW30HRLE-440 to deliver exceptional water purity while operating at a 33% lower pressure requirement compared to standard brackish water elements, significantly reducing energy consumption and overall operating expenses (OPEX). With a substantial active membrane area of 440 square feet (41 square meters) and an optimized 28-mil feed spacer thickness, this element maximizes throughput, yielding an outstanding permeate flow rate of 12,650 gallons per day (48 cubic meters per day) under standard 150 psi testing conditions.
In addition to its immense flow capacity, the FilmTec™ BW30HRLE-440 guarantees exceptional separation performance, boasting a stabilized salt rejection rate of 99.3% and a minimum salt rejection of 99.1%. This precision filtration capability ensures excellent rejection of difficult-to-remove constituents, specifically including silica, boron, nitrate, isopropyl alcohol (IPA), and ammonium. Such advanced rejection parameters make it a critical component for high-stakes environments like ultrapure water systems, semiconductor manufacturing, and complex second-pass reverse osmosis configurations. The element is structurally fortified with a robust fiberglass outer wrap and is equipped with a high-integrity U-cup brine seal and durable end caps to withstand rigorous, high-flow operational environments without mechanical deformation.
Operationally, the BW30HRLE-440 is designed for maximum resilience and extended lifecycle performance, decisively lowering the Total Cost of Ownership (TCO) for facility operators. It accommodates a continuous operating pH range of 2 to 11 and provides the industry-leading widest short-term cleaning pH range of 1 to 13. This extraordinary chemical tolerance facilitates highly effective clean-in-place (CIP) procedures, allowing maintenance teams to utilize robust cleaning agents to remove stubborn biological, organic, and mineral scaling without degrading the membrane matrix. The element safely handles maximum feed flows up to 75 gallons per minute (17 cubic meters per hour) and extreme operating pressures of 600 psi (41 bar). It sustains operational temperatures of 113°F (45°C), though operators must restrict temperatures to 95°F (35°C) when processing feedwater above a pH of 10. To safeguard the polyamide layer from severe oxidative degradation, the feedwater must strictly maintain a free chlorine tolerance of < 0.1 ppm. By deploying the FilmTec™ BW30HRLE-440, plant managers secure an ultra-reliable, compliant, and highly energy-efficient filtration component.
Applications & Industry Use-Cases
- Industrial Water Demineralization: Utilizes the powerful 99.3% stabilized salt rejection rate to extract trace minerals from process water, protecting heavy manufacturing machinery from scaling and corrosion.
- Second Pass RO Configurations: Serves as an excellent polishing stage in dual-pass RO systems due to its superior capability in rejecting stubborn ions like boron, silica, and nitrate.
- Food & Beverage Processing: Fully compliant with USA FDA 21 CFR § 177.2550, enabling safe processing of liquid foods and the production of highly purified water for food manufacturing.
- Ultrapure Water (UPW) Generation: Essential for the microelectronics and pharmaceutical industries where extremely low ionic loads are required, relying heavily on the element's rejection of ammonium and isopropyl alcohol (IPA).
- Seawater Desalination Polishing: Operates highly effectively as a secondary filtration unit in large-scale seawater desalination plants to bring final product water up to stringent municipal and industrial quality standards.
- Large-Scale Utility Water Generation: Specifically designed for large commercial systems producing over 10 gpm, maximizing total water throughput per pressure vessel with its massive 440 ft² active area.
Cross-Compatibility & System Integration
The FilmTec™ BW30HRLE-440 is manufactured to standard 8-inch industrial sizing conventions, measuring 40.0 inches (1,016 mm) in overall length and 7.9 inches (201 mm) in outer diameter. This standard geometry ensures seamless cross-compatibility and allows the element to act as a drop-in replacement or high-efficiency upgrade for existing standard 8-inch reverse osmosis pressure vessels used across commercial water treatment facilities.
For direct and immediate system integration, DuPont supplies connection hardware with every membrane. Each BW30HRLE-440 element ships with a specialized central coupler (DuPont part number 313198), which includes two 3-912 EPR O-rings (DuPont part number 151705) seated to seal the 1.125-inch inner diameter permeate tube securely. This ensures leak-free coupling between membranes when arrayed sequentially within a multi-element pressure vessel.
When engineering multi-element pressure vessel configurations, operators should note that the BW30HRLE-440 produces a maximum pressure drop of 15 psi (1.0 bar) per individual element. When loaded into a pressure vessel with a minimum of 4 elements, system architects must account for a maximum pressure drop of 50 psi (3.5 bar) per vessel. Compatibility with existing high-pressure pumps and feed manifolds should be verified against the maximum allowable feed flow of 75 gpm to ensure long-term, damage-free operation.
