SW30HRLE-370-34i

Summary

Product identification

The FilmTec™ SW30HRLE-370/34 Element is a seawater reverse osmosis (RO) element designed for high-quality water production and reduced capital/operation costs in seawater RO systems. It is a spiral-wound element utilizing a polyamide thin-film composite membrane.

Key features include:

• A wide 34-mil feed spacer to minimize pressure drop and enhance cleaning.
• An active area of 370 ft² (34.4 m²) for maximized productivity.
• Effective use in permeate-staged seawater desalination systems.
• Durable performance with a wide cleaning pH range (1 – 13).
• Automated, precision fabrication with shorter membrane leaves to reduce fouling effects.

Product water

The typical properties are normalized to conditions of 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, and 8% recovery.

• Permeate Flowrate: 6,700 gpd (25 m³/d)
• Stabilized Boron Rejection: 92%
• Stabilized Salt Rejection: 99.80%
• Minimum Salt Rejection: 99.65%

Permeate flows for individual elements may vary ± 15%. Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 1,200 psig (83 bar)
• Maximum Element Pressure Drop: 15 psig (1.0 bar)
• pH Range (Continuous Operation): 2 – 11
• pH Range (Short-term Cleaning, 30 min): 1 – 13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm (removal of free chlorine by pretreatment is recommended due to potential for premature membrane failure)

Mechanical / hydraulic

The element is designed to fit a nominal 8-inch (203 mm) I.D. pressure vessel.

• Active Area: 370 ft² (34.4 m²)
• Feed Spacer Thickness: 34 mil

Dimensions (inches / mm):

• A: 40.0 in (1,016 mm)
• B: 1.125 ID in (29 ID mm)
• C: 7.9 in (201 mm)
