The DOW FilmTec™ SW30HRLE-440i RO Membrane is a high-performance seawater reverse osmosis element. We designed it for seawater desalination. Additionally, it supports high-salinity water treatment applications.
Product Overview
The DOW FilmTec™ SW30HRLE-440i RO Membrane is a high-performance seawater reverse osmosis membrane element designed for seawater desalination and high-salinity water treatment applications. It combines high water productivity with excellent salt and boron rejection for reliable permeate quality.
With a 440 ft² (41 m²) active membrane area, 8,000 GPD (30.2 m³/day) permeate flow, and 99.80% stabilized salt rejection, the SW30HRLE-440i is designed for municipal and industrial seawater desalination systems. It features a 28-mil feed spacer and iLEC™ interlocking end caps for efficient installation, maintenance, and reliable operation.
Key Features
- High Salt Rejection: Up to 99.80% stabilized salt rejection.
- High Productivity: 8,000 GPD permeate flow under specified test conditions.
- High Boron Rejection: 92% stabilized boron rejection.
- Large Active Area: 440 ft² (41 m²) helps maximize system productivity.
- Low Maintenance: iLEC™ interlocking end caps help reduce O-ring leak risks and simplify installation.
- Reliable Performance: Designed for stable, long-term operation.
- Seawater Application: Suitable for medium- and high-salinity feedwater.
