*Permeate flow and salt rejection based on the following test conditions: 2,000 ppm NaCl, applied pressure of 225 psig (15.5 bar), 77F (25C), and 15% 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).
