BW30XFR-400/34

Summary

Product identification

The FilmTec™ BW30XFR-400/34 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 challenging waters and wastewaters, offering high performance, long element life, increased productivity, and high water quality with excellent fouling resistance.

Key features:

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

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
• pH Range, Short-Term Cleaning (30 min.): 1–13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm

Product water

• Permeate Flow Rate: 11,500 GPD (43.5 m³/d)
• Typical Stabilized Salt Rejection: 99.65%
• Minimum Salt Rejection: 99.4%

These values are based on standard test conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, 15% recovery. Flow rates for individual elements may vary by no more than ± 15%. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use.

Mechanical / hydraulic

• Active Area: 400 ft² (37 m²)
• Feed Spacer Thickness: 34-LDP
• Dimensions:
  • Length (A): 40.0 in (1,016 mm)
  • Permeate tube ID (B): 1.125 ID (29 ID mm)
  • Diameter (C): 7.9 in (201 mm)
• Element designed to fit nominal 8-inch (203-mm) I.D. pressure vessels.
