DuPont FilmTec SW30-2521 (Seawater RO Membrane)
📝 Product Description
The DuPont FilmTec SW30-2521 is a high-performance Seawater Reverse Osmosis (SWRO) membrane element, designed specifically for marine (yacht/boat) and small commercial desalination systems. As a 2.5-inch diameter by 21-inch long thin-film composite (TFC) element, the SW30-2521 delivers an impressive 300 GPD of treated water at a high stabilized salt rejection rate of under standard test conditions. The element is engineered to operate efficiently at a test pressure of 800 PSI, offering reliable, high-quality potable water production. The SW30 elements are known for their high flux, allowing for potential operation at lower pressures to help reduce energy consumption and minimize wear on high-pressure pumps. This compact and robust element fits into standard 2.5-inch I.D. pressure vessels.
