BW30HR-440

Summary

Product identification

The FilmTec™ BW30HR-440 Element is a spiral-wound element with a polyamide thin-film composite membrane.

It is designed for reverse osmosis plant managers and operators dealing with controlled pre-treatment waters, seeking consistency, high performance, long element life, increased productivity, higher water quality, outstanding fouling resistance, and reduced footprint installations.

Key features include:

• Delivers high quality permeate water while minimizing CAPEX and OPEX.
• Offers increased active area with highly effective cleaning performance, robustness, and durability due to its wide cleaning pH range (1-13) and chemical tolerance.

Performance specifications

Typical properties based on standard test conditions (2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, 15% recovery):

• Active Area: 440 ft² (41 m²) (guaranteed ± 3%)
• 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: 99.7 %
• Minimum Salt Rejection: 99.4 %
  • Stabilized salt rejection is generally achieved within 24-48 hours of continuous use.

Mechanical / hydraulic

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

Dimensions (nominal):

• A: 40.0 in (1,016 mm)
• B (ID): 1.125 in (29 mm)
• C: 7.9 in (201 mm)

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
  • DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure, as oxidation damage is not covered under warranty.

Additional important information

• The use of this product does not necessarily guarantee the removal of cysts and pathogens from water. Effective reduction is dependent on the complete system design, operation, and maintenance.
• This product may be subject to drinking water application restrictions in some countries; check application status before use and sale.
