Summary
Product identification
- Product: FilmTec™ SW30XLE-440i Element
- Description: Seawater Reverse Osmosis Element with iLEC™ Interlocking Endcaps
- Product Type: Spiral-wound element with polyamide thin-film composite membrane
- Applications:
- Medium-salinity and medium-temperature feedwaters, offering high productivity and high rejection through extra-low energy consumption and single-pass design.
- Suitable for two-pass seawater designs or high salinity brackish water applications.
- Key Features:
- High active area of 440 ft² (41 m²) for low system capital cost and high productivity.
- Thick feed spacer (28 mil) allows for low cleaning frequency and high cleaning efficiency.
- iLEC™ Interlocking Endcaps help reduce operating costs and O-ring leak risks.
- Sustainable high performance over the operating lifetime; not produced with oxidative treatments, leading to greater durability and effective cleaning over a wider pH range (1–13).
- Effective use in permeate staged seawater desalination systems.
