💧 DuPont FilmTec™ SW30-2540 Seawater RO Element
Product Description
The DuPont FilmTec™ SW30-2540 is a durable, high-rejection Seawater Reverse Osmosis (SWRO) element, built for the demanding conditions of commercial and marine desalination systems. This 2.5-inch diameter element utilizes advanced thin-film composite (TFC) technology to deliver consistently high-quality permeate by achieving a stabilized salt rejection of 99.7% or better. Designed for high-pressure operation, the element is tested at 800 PSI to produce a nominal flow rate of 600 Gallons Per Day (GPD). The SW30-2540 is the standard choice for small-scale desalination, marine watermakers, and small municipal systems where space is limited and reliable removal of high salt concentrations is critical.
