SW30XHR-440i

Summary

Product identification

The FilmTec™ SW30XHR-440i Element is a premium seawater reverse osmosis (RO) element, designed to produce high-quality water and reduce capital and operation costs for desalination systems. It is a spiral-wound element with a polyamide thin-film composite membrane and features iLEC™ Interlocking Endcaps.

Key benefits include:

• Highest NaCl and boron rejection, helping meet World Health Organization (WHO) and other drinking water standards cost-effectively.
• Highest guaranteed active area of 440 ft² (41 m²) to maximize productivity and enable accurate system design.
• A combination of high active area and a thick 28 mil feed spacer, allowing for low cleaning frequency and high cleaning efficiency.
• Utilization of the distinct iLEC™ Interlocking Endcaps to reduce operating costs and minimize O-ring leak risks.
• Sustainable high performance over its operating lifetime, due to membrane production without oxidative treatments, which allows for a wider cleaning pH range (1 – 13).
• Effective use in permeate staged seawater desalination systems without impairing downstream stage performance.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Note: Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 1,200 psig (83 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
  • Note: Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Oxidation damage is not covered under warranty, and removal of residual free chlorine by pretreatment is recommended.

Product water

Benchmark values are based on the following test conditions: 32,000 ppm NaCl, 800 psi (5.5 MPa), 77°F (25°C), pH 8, and 8% recovery.

• Permeate Flowrate: 6,600 gpd (25 m³/d)
  • Note: Permeate flows for individual elements may vary ± 20%.
• Stabilized Boron Rejection: 93%
• Stabilized Salt Rejection: 99.82%
• Minimum Salt Rejection: 99.7%
  • Note: Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use.

Mechanical / hydraulic

• Dimensions:
  • Active Area: 440 ft² (41 m²) (guaranteed ± 5%)
  • Feed Spacer Thickness: 28 mil
  • Net length (A) of elements when connected: 40.0 inches (1,016 mm)
  • Individual element length (B) with iLEC™ Interlocking Endcaps: 40.5 inches (1,029 mm)
  • Diameter (C): 7.9 inches (201 mm)
  • Internal Diameter (D): 1.125 ID (29 ID)

Additional Important Information

• Permeate obtained from the first hour of operation should be discarded.
• The use of this product in itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective reduction depends on complete system design, operation, and maintenance.
• This product may be subject to drinking water application restrictions in some countries; users should check the application status before use and sale.
