1) Sea Water Reverse Osmosis Membrane
2) Size: 4" x 40" inches
3) Flow / GPD: 1950
4) Stabilized Salt Rejection (%): 99.4
Improved Filmtec seawater reverse osmosis elements offer the highest productivity while maintaining excellent salt rejection.
*The above benchmark values are based on the following test conditions: 32,000 ppm NaCl, 800 psi (5.5 MPa), 77°F (25°C), pH 8 and 8% 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).
