BW30XHR PRO 400-34i

Summary

Product Identification

The FilmTec™ BW30XHR PRO-400/34i is an Extra High Rejection Brackish Water Reverse Osmosis Membrane Element.

Key features include:

• Exceptional permeate quality
• Excellent silica, boron, nitrate, TOC, and ammonium rejection
• Excellent durability for stable, long-term performance
• Enhanced fouling protection due to a 34 mil feed spacer
• iLEC™ interlocking end caps, designed to reduce system operating costs and the risk of o-ring leaks

Key applications for this element include:

• Demineralization for industrial uses (e.g., Power Generation, Steel & Metal, Chemical & Petrochemical)
• Municipal water purification
• Applications requiring stringent permeate quality

Operating Limits

• Membrane Type: Polyamide Thin-Film Composite

  • Note: Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 600 psig (41 bar)
• Maximum Pressure Drop:
  • Per Element: 15 psig (1.0 bar)
  • Per Pressure Vessel (Minimum 4 Elements): 50 psig (3.5 bar)
• pH Range:
  • Continuous Operation: 2 - 11
  • Short-Term Cleaning (30 min.): 1 - 13
• Maximum Feed Flow: 75 gpm (17 m³/hr)
• Maximum Feed Silt Density Index: SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • Note: Oxidation damage is not covered under warranty; removal of residual free chlorine by pretreatment is recommended.

Product Water

• Stabilized Salt Rejection: 99.8%
• Minimum Salt Rejection: 99.6%
• Typical Permeate Flow Rate: 11,500 gpd (43.5 m³/d)

Performance is based on standard conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8 and 15% recovery. Flow rates for individual elements may vary but will be no more than 15% below the value shown.

Mechanical / Hydraulic

• Active Area: 400 ft² (37 m²)
• Feed Spacer Thickness: 34-LDP mil
• Dimensions:
  • A (Net length when elements are connected): 40.0 inches (1,016 mm)
  • B (Individual element length with iLEC™ Interlocking Endcaps): 40.5 inches (1,029 mm)
  • C (Diameter): 7.9 inches (201 mm)
  • D (ID): 1.125 ID (29 mm)

General Information

• Elements should be kept moist at all times after initial wetting.
• To prevent biological growth during prolonged system shutdowns, immersion in a preservative solution is recommended.
• Avoid static permeate-side backpressure at all times.
• Permeate from the first hour of operation should be discarded.
• The use of this product does not guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
