Dupont FilmTec™ BW30FR-400/34 Element

Description FilmTec™ BW30FR-400/34 is an fouling resistant membrane

element that is suitable for dealing with highly polluted water

sources, and has fouling resistance, high rejection and high

productivity.

l Offers highly effective cleaning performance, robustness

and durability due to its widest cleaning pH range (1 – 13)

tolerance and the support of FilmTec™ technical

representatives

l A wide 34-mil feed spacer to lessen the impact of fouling

on pressure drop across a vessel and enhance cleaning

effectiveness

l Automated, precision fabrication with membrane leaf efficiencies optimized to

reduce the overall effect of fouling

Product Type Spiral-wound element with polyamide thin-film composite membrane

1. Permeate flow and salt (NaCl) rejection based on the following standard test conditions: 2,000 ppm NaCl,

225 psi (15.5 bar), 77°F (25°C), pH 8, 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 feedwater 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.
