FilmTec™ SW30XLE-440(i)

Summary

Product identification

The FilmTec™ SW30XLE-440i Element is a seawater reverse osmosis (RO) element featuring iLEC™ Interlocking Endcaps. It is a spiral-wound element with a polyamide thin-film composite membrane.

It is designed to reduce capital and operational costs for desalination systems, offering high productivity and rejection for medium-salinity and medium-temperature feedwaters with extra-low energy consumption in a single-pass design. It is also suitable for two-pass seawater designs or high salinity brackish water applications.

Key features include:

• High active area of 440 ft² (41 m²) to maximize productivity and enable predictable system design and operating flux.
• Thick feed spacer (28 mil) combined with high active area allows for low cleaning frequency and high cleaning efficiency.
• iLEC™ Interlocking Endcaps reduce system operating costs and mitigate O-ring leak risks.
• Sustainable high performance over its operating lifetime due to the absence of oxidative treatments in membrane production, allowing for a wider pH cleaning range (1 – 13).
• Effective in permeate staged seawater desalination systems without affecting downstream stage performance.

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: 1,200 psig (83 bar)
• Maximum Element Pressure Drop: 15 psig (1.0 bar)

Feed water

• 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
  • The presence of free chlorine and other oxidizing agents can cause premature membrane failure; removal by pretreatment is recommended.

Additional important information

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