SU-720L

Summary

Product identification

• Model: SU-720L High flow RO element for brackish water
• Membrane Type: Cross Linked Fully Aromatic Polyamide Composite
• Element Configuration: Spiral Wound

Performance Specification

• Salt Rejection:
  • Average: 99.0 %
  • Minimum: 98.0 % (for any single element)
• Product Flow Rate:
  • Average: 22 m³/day (5800 gpd)
  • Minimum: 20 m³/day (5280 gpd) (for any single element)

Test Conditions (for performance specifications):

• Feed Water Pressure: 1.0 MPa (150 psi)

• Feed Water Temperature: 25 °C (77 °F)

• Feed Water Concentration: 1500 mg/L as NaCl

• Brine Flow Rate: 80 L/min (5.3 gpm)

• Feed Water pH: 6.5

• Note: Average values are for 100 elements after 1 hour of operation.

• Membrane Surface Area: Nominal 28 m² (300 ft²)

  • Note: The membrane area stated is a nominal value and is not a guaranteed specification.

Operating limits

• Feed Water Pressure:
  • Recommended: 1.5 MPa (220 psi)
  • Maximum: 4.1 MPa (600 psi)
• Feed Water Temperature:
  • Recommended: 35 °C (95 °F)
  • Maximum: 45 °C (113 °F)
• Feed Water Turbidity (SDI): 4 (measured according to ASTM D4189)
  • Note: High flux operation on feed water turbidity greater than 3 or 4 SDI generally results in frequent cleaning requirements.
• Feed Water pH Range (Continuous Operation): 3 – 9
• Feed Water pH Range (Chemical Cleaning): 2 – 10
• Feed Flow Rate per Vessel: 200 L/min (53 gpm)
• Brine Flow Rate per Vessel: 40 L/min (11 gpm)
• Brine/Permeate Flow Ratio: 6 (at last element)
  • Note: This figure is reducible when there is less possibility of fouling and scaling.
• Pressure Drop (per Element): 0.10 MPa (14 psi)
• Pressure Drop (per Vessel): 0.20 MPa (29 psi)
  • Note: Element(s) must be cleaned when pressure drop increases up to 1.5 times of initial value.

Mechanical / hydraulic

• Dimensions: All dimensions are shown in millimeters in the official PDF. The element has an overall length of 1016 mm. Diagrams indicate permeate and concentrated brine flow directions.
