🧪 FilmTec BW30XFRLE-400/34 Brackish Water RO Membrane
The FilmTec™ BW30XFRLE-400/34 is an industry-leading, high-performance reverse osmosis membrane designed for challenging brackish water applications. This element is specifically engineered for operators seeking a balance of high permeate quality, exceptional energy efficiency, and superior resistance to biological and organic fouling. By utilizing DuPont’s advanced low-energy membrane chemistry, the BW30XFRLE-400/34 delivers stabilized salt rejection of 99.3% while operating at significantly lower pressures than standard brackish water elements, reducing overall system energy consumption by up to 30%.
What sets this model apart is the integration of an optimized 34 mil feed spacer. This extra-thick spacer reduces the impact of fouling and enhances cleaning effectiveness by improving hydrodynamics within the element. With a massive 400 square feet of active membrane area, this 8-inch diameter element allows system designers to maximize productivity or reduce the total number of membranes required in a system. Its robust fiberglass outer shell and wide cleaning pH range (1–13) ensure long-term durability and the ability to withstand aggressive cleaning cycles, making it the premier choice for industrial water demineralization and municipal water reuse projects.
