Description
HSRO-390-FF 8″ FilmTec DOW membrane: Reverse osmosis disinfectable with hot water.
Discover DuPont (Dow) FilmTec HSRO-390-FF 8″ x 40″ membrane, a heat disinfection reverse osmosis (HSRO) element that offers high purity water and resistance to hot water disinfection. This feature reduces the use of chemical disinfectants and saves operating costs in applications such as sterile water for injection and dialysis.
Manufactured with advanced automated equipment, the HSRO-390-FF membrane features a high active membrane area, allowing system designers to opt for a lower operating flux to minimize fouling or achieve desired performance with fewer membrane elements, saving costs and reducing the systems footprint. In addition, its full-fit design minimizes stagnant areas, which is optimal for applications requiring a sanitary design.
All components of the HSRO-390-FF membrane meet U.S. Food and Drug Administration (FDA) standards. The elements are available in wet and dry versions.
Take advantage of the benefits and applications of the FilmTec HSRO-390-FF membrane in the production of sterile water for injection, dialysis and other applications requiring high purity water and heat disinfection. Choose DuPont for innovative and efficient reverse osmosis solutions to improve water quality in your projects.
