HRLE-440i

Summary

Product identification

The FilmTec™BW30HRLE-440i is a spiral-wound element with a polyamide thin-film composite membrane. It is designed for reverse osmosis plant managers and operators who require advanced membrane treatment with good water purity and low energy consumption, especially with controlled-pre-treatment waters.

Key features include:

• Offers 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.
• Includes iLEC™ interlocking end caps, which reduce system operating costs and the risk of o-ring leaks.

The element is designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

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

Feed water

• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure, as oxidation damage from free chlorine and other oxidizing agents can cause premature membrane failure and is not covered under warranty.

Product water

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

Mechanical / Hydraulic

• Active Area: 440 ft² (41 m²)
  • Active area guaranteed ± 3%.
• Feed Spacer Thickness: 28 mil
• Element Dimensions (BW30HRLE-440i):
  • Overall Length (B, with iLEC™ endcaps): 40.5 inches (1,029 mm)
  • Net Length (A, when connected): 40.0 inches (1,016 mm)
  • Diameter (C): 7.9 inches (201 mm)
  • Permeate Tube ID (D): 1.125 inches (29 mm)
