SW30HRLE-440i

Summary

Product identification

The FilmTec™ SW30HRLE-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.

Key benefits and features include:

• Sustainable lower life-cycle cost for medium- and high-salinity feedwater.
• High NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
• Very high guaranteed active area of 440 ft² (41 m²), maximizing productivity.
• A thick feed spacer (28 mil) allows low cleaning frequency and high cleaning efficiency.
• Utilization of iLEC™ Interlocking Endcaps, which help reduce operating costs and the risk of O-ring leaks.
• Sustainable high performance over the operating lifetime, as oxidative treatments are not used in membrane production, allowing effective cleaning over a wider pH range (1–13).
• Effective use in permeate staged seawater desalination systems without impairing downstream performance.

Performance 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.

Typical Properties (for SW30HRLE-440i):

• Active Area: 440 ft² (41 m²)
• Permeate Flowrate: 8,000 gpd (30.2 m³/d)
• Stabilized Boron Rejection: 92%
• Stabilized Salt Rejection: 99.80%

Notes:

• Permeate flows for individual elements may vary ± 15%.
• Stabilized salt rejection is generally achieved within 24–48 hours of continuous use.
• The active area is guaranteed ± 5%.
• Discard permeate obtained from the first hour of operation.
• The use of this product does not necessarily guarantee the removal of cysts and pathogens; this is dependent on the complete system design, operation, and maintenance.
