FilmTec™ BW30HRLE-440 Membrane element

Typical Properties

• Active area – 41 m²
• Feed spacer thickness – 28 mil
• Permeate flow rate – 48 m³/d
• Typical Stabilized Salt – 99.3%
• Minimum Salt(ft Rejection – 99.1%

a. Permeate flow and salt (NaCl) rejection based on the following standard test conditions: 2,000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, 15% recovery.

b. Flow rates for individual elements may vary but will be no more than ± 15%.

c. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.

d. Sales specifications may vary as design revisions take place.

e. Active area guaranteed ± 3%. Active area as stated by DuPont Water Solutions is not comparable to nominal membrane area often stated by some manufacturers.
