• Description: Seawater Reverse Osmosis Element
• Product Type: Spiral-wound element with polyamide thin-film composite membrane

Product water

• Permeate Flowrate: 7,500 gpd (28 m³/d)
  • Note: Permeate flows for individual elements may vary ± 15%.
• Stabilized Salt Rejection: 99.80%
  • Note: Minimum Salt Rejection is 99.65%.
  • Note: Stabilized salt rejection is generally achieved within 24–48 hours of continuous use.
• Stabilized Boron Rejection: 92%
• Normalization Conditions: Values are normalized to 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.
• Cyst and Pathogen Reduction: The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
• Initial Operation: Permeate obtained from the first hour of operation should be discarded.

Mechanical / hydraulic

• Active Area: 400 ft² (37 m²)
  • Note: Active area guaranteed ± 5%.
• Feed Spacer Thickness: 28 mil
• Element Dimensions (inches/mm):
  • A: 40.0 in (1,016 mm)
  • B: 1.125 ID (29 ID mm)
  • C: 7.9 in (201 mm)
• Pressure Vessel Fit: Element is designed to fit nominal 8-inch (203-mm) I.D. pressure vessel.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Note: 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)
