BW30HRLE-440

Summary

Product identification

The FilmTec™ BW30HRLE-440 Element is a spiral-wound element with a polyamide thin-film composite membrane.

It is described as 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.

Key features include:

• Good salt-rejection with 33% lower pressures.
• Delivers excellent silica, boron, nitrate, IPA and ammonium rejection.
• Provides increased active area with effective cleaning performance, robustness and durability due to its widest cleaning pH range (1-13) and chemical tolerance.

Product water

The following typical properties are based on standard test conditions of 2,000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, and 15% recovery:

• Permeate Flow Rate:
  • 12,650 GPD
  • 48 m³/d
  • Flow rates for individual elements may vary but will be no more than ± 15%.
• Typical Stabilized Salt Rejection: 99.3%
• Minimum Salt Rejection: 99.1%
  • Stabilized salt rejection is generally achieved within 24-48 hours of continuous use, depending upon feedwater characteristics and operating conditions.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 600 psig (41 bar)
• Maximum Element Pressure Drop: 15 psig (1.0 bar)
• pH Range:
  • Continuous Operation: 2 – 11
  • Short-Term Cleaning (30 min.): 1 – 13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure.

Mechanical / hydraulic

• Active Area:
  • 440 ft²
  • 41 m²
  • Active area guaranteed ± 3%.
• Feed Spacer Thickness: 28 mil
• Element Dimensions (BW30HRLE-440):
  • A: 40.0 in (1,016 mm)
  • B (ID): 1.125 in (29 mm)
  • C: 7.9 in (201 mm)
  • Element to fit nominal 8-inch (203-mm) I.D. pressure vessel.
