FilmTec™ BW30XFRLE-400/34 Membrane Element
Ideal for: reverse osmosis plant managers and operators dealing with challenging waters and wastewaters who are seeking anadvanced membrane treatment with good water purity, improved fouling resistance and low energy consumption.
Product type
Spiral-wound element with polyamide thin-film composite membrane
Typical properties
- Nominal active surface - 37 m²
- 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), 77°F (25°C), pH 8 and 15% recovery.
2. Flow rates for individual elements may vary but will be no more than ±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 ± 3%. Active area as stated by DuPont Water Solutions is not comparable to nominal membrane area often stated by some manufacturers.
