FilmTec™ SW30HRLE-370/34(i)

Summary

Product identification

The FilmTec™ SW30HRLE-370/34 Element is a seawater reverse osmosis (RO) element designed to produce high-quality water, reduce capital, and lower operation costs. It is a durable, high-rejection, high-productivity element suitable for high-fouling or challenging feedwater conditions.

Benefits include:

• A wide 34-mil feed spacer to lessen the impact of fouling on pressure drop and enhance cleaning effectiveness.
• An active area of 370 ft², maximizing productivity and enabling accurate and predictable system design.
• Effective use in permeate-staged seawater desalination systems without impairing downstream stage performance.
• High performance over the operating lifetime without oxidative posttreatments. These elements are more durable and can be cleaned 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.

Product Type: Spiral-wound element with polyamide thin-film composite membrane.

Typical Properties

• FilmTec™ Element: SW30HRLE-370/34
• Active Area: 370 ft² (34.4 m²)
• Feed Spacer Thickness: 34 mil
• Permeate Flowrate: 6,700 gpd (25 m³/d)
• Stabilized Boron Rejection: 92%
• Stabilized Salt Rejection: 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%.
