💧 DuPont FilmTec BW30 PRO-4040 Brackish Water RO Membrane

The DuPont FilmTec BW30 PRO-4040 is a high-performance Brackish Water Reverse Osmosis Element engineered for commercial and light-industrial water treatment systems. Built with DuPont's advanced PRO series polyamide thin-film composite chemistry, this 4-inch membrane is designed to deliver consistent, high-quality permeate while providing exceptional durability against fouling and chemical degradation. It is widely utilized in commercial water purification, car wash spot-free rinses, and food and beverage processing where reliable, high-purity water is critical

Operating at a standard test pressure of 225 PSI, the BW30 PRO-4040 produces an impressive nominal flow rate of 2,500 Gallons Per Day (GPD). It features an upgraded 87 square foot active surface area and a robust 34-mil feed spacer, which significantly reduces the impact of particulate fouling and minimizes the pressure drop across the element. This advanced design not only ensures a high stabilized salt rejection of 99.5%, but also extends the operational lifespan of the membrane, reducing the frequency of cleanings and lowering overall system maintenance costs.
