*Permeate flow and salt passage based on the following test conditions: 500 mg/l CaCl2, 70 psi (0.48 MPa), 77ºF (25ºC) and 15% recovery. 2,000 mg/l MgSO4, 70 psi (0.48 MPa), 77ºF (25ºC) and 15% recovery. Flow rates 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).
