SU-720TS

Summary

Product Identification

• Model: SU-720TS High rejection RO element
• Membrane Type: Cross Linked Fully Aromatic Polyamide Composite
• Element Configuration: Spiral Wound

Performance Specification

• Salt Rejection: 99.4 % (99.0 % minimum for any single element)
• Product Flow Rate: 26 m³/day (6900 gpd) (22 m³/day (5810 gpd) minimum for any single element)

Test Conditions (for Performance Specification)

• Feed Water Pressure: 1.5 MPa (220 psi)
• Feed Water Temperature: 25 °C (77 °F)
• Feed Water Concentration: 1500 mg/L as NaCl
• Brine Flow Rate: 80 L/min. (21 gpm)
• Feed Water pH: 6.5

Operating Limits (Recommended Design Conditions)

• Feed Water Pressure:
  • Recommended: 2.0 MPa (286 psi)
  • Maximum: 4.1 MPa (600 psi)
• Feed Water Temperature:
  • Recommended: 35 °C (95 °F)
  • Maximum Sanitization Temperature: 85 °C (185 °F)
• Feed Water pH Range:
  • Continuous Operation: 3 – 9 (applies to feed and brine water)
  • Chemical Cleaning: 2 – 11
• Feed Water Turbidity (SDI): Recommended 4
  • Note: SDI = Silt Density Index 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.

Mechanical / Hydraulic

• Dimensions:
  • Length: 1016 mm
  • Other dimensions shown in diagram: 22 mm, 15 mm. (All dimensions shown in millimeters.)
  • Flow direction: Permeate, Feed Water (F), Concentrated Brine (B).
• Flow Rate per Vessel (Recommended):
  • Feed Flow Rate: 200 L/min. (52.8 gpm)
  • Brine Flow Rate: 40 L/min. (10.6 gpm)
• Brine/Permeate Flow Ratio (Recommended): 6 (ratio at last element)
  • Note: This figure is reducible when there is less possibility of fouling and scaling.
• Pressure Drop (Recommended):
  • Per Element: 0.10 MPa (14 psi)
  • 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.
• General Note: The recommended design range is for operational and design conditions under not so much fouling and scaling. Operating outside this range may reduce effective membrane life. Sterilization must follow guidance in Toray's technical bulletin. Cleaning chemicals shall be followed to Toray's technical bulletins.
