HSRO-390-FF DuPont FilmTec 9,000 GPD at 150 PSI 8 x 40 inch Membranes

DuPont FilmTec HSRO-390-FF Heat Sanitizable RO Membrane

The DuPont FilmTec HSRO-390-FF is an industrial-grade, full-fit reverse osmosis (RO) membrane engineered for applications requiring advanced water purification and strict sanitary design. Manufactured using high-performance polyamide thin-film composite technology, this 8-inch by 40-inch spiral-wound element is specifically designed to be heat sanitizable. This advanced capability allows the membrane to withstand hot water sanitization protocols up to 185°F (85°C), effectively eliminating the need for chemical sanitizers. It is an industry standard for mission-critical operations such as pharmaceutical production, medical water, biotechnology, and food processing where stringent sanitary conditions must be continuously maintained.

Designed to maximize productivity and system hygiene, the HSRO-390-FF features a full-fit configuration that eliminates the outer shell to minimize stagnant areas where bacteria could otherwise proliferate. The element delivers a reliable permeate flow rate of 9,000 GPD with a stabilized salt rejection of 99.5%. Operating efficiently at a standard test pressure of 150 PSI, it provides 390 square feet of active membrane surface area, allowing system engineers to design for lower operating flux or achieve the desired capacity with fewer elements. Built for durability, this robust RO membrane safely accommodates a maximum applied pressure of 600 PSI and complies with U.S. Food & Drug Administration (FDA) standards, providing a long-lasting, high-purity solution for continuous-duty sanitary environments.
