Dow Filmtec SW30HRLE-4040 40 inch × 4 inch Sea Water Desalination Membrane
Filmtec SW30HR LE-4040 reverse osmosis element is a four-inch diameter version of SW30HR LE-400, the industry’s leading seawater element which offers an unprecedented combination of high salt rejection and productivity to enable the lowest total cost of purifying high salinity water.
*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).
Note: Active surface area guaranteed +/-5%. Active area as stated by FilmTec is not comparable to nominal membrane area often stated by some manufacturers.
Hours of Operation (CST): 8:00am - 4:30pm Mon-Thur & 8:00am - 3:30pm Fri
