Summary
Product identification
The FilmTec™ SW30HRLE-400 Element is a seawater reverse osmosis (RO) element featuring a spiral-wound design with a polyamide thin-film composite membrane.
It is designed to offer a combination of high rejection and low energy requirements, leading to lower total costs for systems with medium- and high-salinity feedwater.
Benefits include:
- Optimized operating cost through lower energy consumption or optimized capital cost through higher productivity at lower operating fluxes.
- High NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
- Effective use in permeate-staged seawater desalination systems without impairing downstream stage performance.
- High performance over the operating lifetime without the use of oxidative posttreatments, allowing for cleaning over a wider pH range (1 – 13).
- Automated, precision fabrication with a greater number of shorter membrane leaves, reducing the effect of overall fouling and maximizing element efficiency.

Typical Properties:
| FilmTec™ Element | Active Area (ft²) | Active Area (m²) | Feed Spacer Thickness (mil) | Permeate Flowrate (gpd) | Permeate Flowrate (m³/d) | Stabilized Boron Rejection (%) | Stabilized Salt Rejection (%) |
|---|---|---|---|---|---|---|---|
| SW30HRLE-400 | 400 | 37 | 28 | 7,500 | 28 | 92 | 99.80 |
These values are normalized to the following conditions: 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.
- Permeate flows for individual elements may vary ± 15%.
- Minimum Salt Rejection is 99.65%.
- Stabilized salt rejection is generally achieved within 24–48 hours of continuous use.
- Active area is guaranteed ± 5%.

Additional Important Information
- The use of this product alone does not necessarily guarantee the removal of cysts and pathogens from water; 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.
