FilmTec™ BW30HRLE-440 Membrane Element

Ideal for: reverse osmosis plant managers and operators dealing with controlled-pre-treatment waters and seeking advanced membrane treatment with good water purity and low energy consumption.

Offers good salt-rejection with 33% lower pressures

Delivers excellent silica, boron, nitrate, IPA and ammonium rejection

Provides increased active area with the most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1-13) and chemical tolerance and the support of DuPont technical representatives

Permeate flow rate

m³/day

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.
