💧 DuPont FilmTec™ SW30-4021 Seawater RO Element

Product Description

The DuPont FilmTec™ SW30-4021 is a compact, high-performance Seawater Reverse Osmosis (SWRO) element built for reliable operation in small-scale desalination and marine applications (watermakers). This element utilizes FilmTec's robust thin-film composite (TFC) technology, which is engineered to maintain exceptional productivity and salt rejection under high operating pressure.

At the standard test condition of $800\text{ PSI}$, the SW30-4021 delivers a nominal permeate flow of $800\text{ Gallons Per Day (GPD)}$ with a stabilized salt rejection of $99.4\%$. Its small size and high flux capabilities make it the preferred choice for yachts, boats, and small land-based desalination units requiring high-quality potable water from a seawater source. The element is also able to operate at a lower pressure, which can reduce overall energy use.
