*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 10% recovery. Permeate flows for individual elements may vary +/-15%.
**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.
