SU-620F

Summary

Product identification

• Model: SU-620F
• Membrane Type: Cross Linked Polyamide Composite
• Element Configuration: Spiral Wound

Performance Specification

Performance is measured as an average value for 100 elements after 1 hour of operation, under specific test conditions.

Test Conditions:

• Pressure: 3.5 kg/cm² (50 psi)
• Temperature: 25 °C (77 °F)
• Feed Concentration: 500 ppm as NaCl or MgSO₄
• Brine Flow Rate: 80 l/min (21.1 gpm)
• Feed pH: 6.5

NaCl Solution Performance:

• Salt Rejection: 55.0 % (45.0 % minimum for any single element)
• Product Flow Rate: 22.0 m³/day (5,810 gpd)

MgSO₄ Solution Performance:

• Salt Rejection: 99.0 % (98.0 % minimum)
• Product Flow Rate: 18.0 m³/day (4,760 gpd) (16.0 m³/day (4,230 gpd) minimum for any single element)

Operating limits

• Recommended Operating Pressure: < 10 kg/cm² (143 psi)
  • Maximum: 15 kg/cm² (214 psi)
• Feedwater Temperature: < 35 °C (95 °F)
  • Maximum: 45 °C (113 °F)
• Feedwater Turbidity (SDI₁₅): < 4 (measured according to ASTM D4189)
  • High flux operation with feedwater turbidity greater than 3 or 4 SDI₁₅ generally results in frequent cleaning requirements.
• Feedwater Chlorine Concentration: < 1 ppm
  • Product flow rate declines 25 - 30% when feedwater contains Chlorine.
• pH Range, Continuous Operation: 3 - 8 (both feed and brine water must meet this range)
• pH Range, Chemical Cleaning: 2 - 10
• Feed Flow Rate per Vessel: < 200 l/min (52.8 gpm)
• Brine Flow Rate per Vessel: > 40 l/min (10.6 gpm)
• Brine/Permeate Flow Ratio: > 6 (flow ratio for each single element)
• Pressure Drop (per Element): < 1 kg/cm² (14 psi)
• Pressure Drop (per Vessel): < 2 kg/cm² (29 psi)
  • Pressure drop figures may be reduced when there is hardly any fouling and scaling.
  • Element(s) must be cleaned when pressure drop increases to 1.5 times of the initial value.
