-
High active area (400 square feet) for more productivity without increasing the operating flux.
-
High rejection DOW FILMTEC RO membrane that has a wide pH cleaning range (pH 1-13) that allows for effective cleaning of scale, organic compounds, and biofilm.
-
Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.
These features offer system operators some of the best long-term economics and most trouble-free operation for RO membrane purification of fouling water.

- Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.5 bar), 77°F (25°C), pH 8 and 15% recovery.
- Permeate flow rates for individual elements may vary, but will be no more than 15% below the value shown.
- Sales specifications may vary as design revisions take place.
- Active area guaranteed +/-3%. Active area as stated by Dow is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
