SC-4101

Summary

Product identification

• Model: SC-4101
• Membrane Type: Modified Cellulose Acetate
• Element Configuration: Spiral Wound

Product water

• Salt Rejection: 97.0 % (96.0 % minimum for any single element)
• Product Flow Rate: 6.8 m³/day (1800 gpd) (5.5 m³/day (1460 gpd) minimum for any single element)

Operating limits

• Performance Test Conditions:
  • Feed Water Pressure: 3.0 MPa (440 psi)
  • Feed Water Temperature: 25 °C (77 °F)
  • Feed Water Concentration: 1500 mg/L as NaCl
  • Brine Flow Rate: 20 L/min. (5.3 gpm)
  • Feed Water pH: 6
• Recommended Design Conditions:
  • Feed Water Pressure: 30 kg/cm² (430 psi)
    • Maximum Feed Water Pressure: 4.1 MPa (600 psi)
  • Feed Water Temperature: 30 °C (86 °F)
  • Feed Water Turbidity (SDI): 4
    • SDI is measured according to ASTM D4189.
    • High flux operation with feed water turbidity greater than 3 or 4 SDI generally results in frequent cleaning requirements.
    • Feed and brine water must meet this range.
  • Feed Water Chlorine Concentration: 0.1 - 0.7 mg/L
  • Feed Water pH Range, Continuous Operation: 4 - 6.5
  • Feed Water pH Range, Chemical Cleaning: 3 - 8.5
  • Feed Flow Rate per Vessel: 50 L/min. (13.2 gpm)
  • Brine Flow Rate per Vessel: 10 L/min. (2.6 gpm)
  • Brine/Permeate Flow Ratio: 6 (ratio at last element; 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)
  • Cleaning: Element(s) must be cleaned when pressure drop increases up to 1.5 times of initial value.
  • Sterilization: Must follow guidances in Toray's technical bulletin.
  • Note: Operating outside the recommended design range may reduce the effective membrane life.

Mechanical / hydraulic

• Dimensions:
  • Overall Length: 1016 mm
  • Other dimensions observed from diagram: 15 mm, 22 mm.
  • See the official PDF for detailed dimensional diagrams illustrating Feed (F), Permeate, and Brine (B) flow directions. All dimensions are shown in millimeters.
