Dupont FilmTec™ BW30HRLE-440 Element
Description 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.
FilmTec™ BW30HRLE-440:
l Offers good salt-rejection with 33% lower pressures
l Delivers excellent silica, boron, nitrate, IPA and
ammonium rejection
l 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
Product Type Spiral-wound element with polyamide thin-film composite membrane

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.
