FilmTecā¢ BW30XFRLE-400/34 membrane element specifications
Product type
Spiral-wound element with polyamide thin-film composite membrane
Typical properties
- Nominal active surface - 37 mĀ²
- Feed Spacer Thickness - 34-LPD mil
- Permeate flow rate - 43.5 m3/day
- Stabilized salt rejection - 99.3%
- Minimum salt rejection - 99.1%
1. Permeate flow and salt rejection based on the following standard conditions: 2,000 ppm NaCl, 150 psi (10.3 bar), 77Ā°F (25Ā°C), pH 8 and 15% recovery.
2. Flow rates for individual elements may vary but will be no more than Ā±15%.
3. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feed water characteristics and operating conditions.
4. Sales specifications may vary as design revisions take place.
5. Active area guaranteed Ā± 3%. Active area as stated by DuPont Water Solutions is not comparable to nominal membrane area often stated by some manufacturers.
