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.
