Summary

Product identification

• Product Name: FilmTec™ BW30 PRO-400/34i
• Membrane Type: Polyamide Thin-Film Composite
• Key Features:
  • Delivers consistent water quality, higher rejection, and flow compared to previous generation BW30.
  • Based on historical BW30 industry-standard RO membrane with decades of proven performance.
  • Excellent durability for stable, long-term performance.
  • Enhanced fouling protection due to a 34 mil feed spacer.
  • Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks.
• Key Applications:
  • Demineralization for industrial applications: Power Generation, Steel & Metal, Chemical & Petrochemical.
  • Municipal water purification.

  • Note: Oxidation damage is not covered under warranty; DuPont recommends removing residual free chlorine by pretreatment.

Product water

Permeate flow and salt rejection are based on standard conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, and 15% recovery.

• Permeate Flow Rate: 11,000 gpd (42 m³/d)
  • Note: Flow rates for individual elements may vary but will be no more than 15% below the value shown.
• Stabilized Salt Rejection: 99.6%
• Minimum Salt Rejection: 99.4%

Mechanical / hydraulic

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

General Information

• Elements must be kept moist at all times after initial wetting.
• Failure to strictly follow operating limits and guidelines will void the warranty.
• For prolonged system shutdowns, elements should be immersed in a preservative solution.
• The customer is responsible for the effects of incompatible chemicals and lubricants.
• 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 inherently guarantee the removal of cysts and pathogens; effective reduction depends on complete system design, operation, and maintenance.

Regulatory Note
