DuPont FilmTec SW30-2521 Seawater RO Membrane
The DuPont FilmTec SW30-2521 is a high-performance, industrial-grade seawater reverse osmosis (RO) membrane engineered for demanding desalination applications. Utilizing advanced polyamide thin-film composite technology, this 2.5-inch by 21-inch spiral-wound element is designed to provide exceptional salt rejection while maintaining high productivity. It is widely specified for continuous-duty commercial and marine watermakers, including yacht desalination systems, offshore platforms, and land-based seawater treatment facilities. The membrane's robust construction ensures reliable, long-term performance even in high-salinity feed water environments.
Designed for operational flexibility, the SW30-2521 delivers a nominal permeate flow rate of 300 GPD (1.1 m³/d) with a stabilized salt rejection of 99.4% under standard test conditions. The element operates at a test pressure of 800 PSI, allowing for efficient separation of dissolved solids from seawater. Its ability to maintain high flux at this pressure range helps minimize energy consumption for high-pressure booster pumps, providing an optimized solution for small-to-medium scale desalination systems. By combining automated precision fabrication with industry-standard membrane chemistry, this element delivers the consistent, reliable liquid purification required for mission-critical marine and industrial systems.
