Dow Filmtec SW30-2521 Reverse Osmosis (RO) Membrane
replacement 300 GPD seawater desalination reverse osmosis (RO) membrane element
Improved Filmtec seawater reverse osmosis elements offer the highest productivity while maintaining excellent salt rejection.
- Filmtec SW30 membrane elements have the highest flow rates available to meet the water demands of both sea-based and land-based desalinators.
- Filmtec SW30 elements may also be operated at lower pressure to reduce pump size, cost and operating expenses.
- Improved Filmtec seawater membrane combined with automated, precision element fabrication result in the most consistent product performance available.

*The above benchmark values are based on the following test conditions: 32,000 ppm NaCl, 800 psi (5.5 MPa), 77F (25C), pH 8 and 4% recovery. Permeate flows for individual elements may vary +/-20%.
**Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow recommends removing residual free chlorine by pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.
***Maximum temperature for continuous operation above pH 10 is 95F (35C).
