SWC6-LD

Summary

Product identification

• Product Name: SWC6-LD
• Configuration: Low Fouling Spiral Wound
• Membrane Polymer: Composite Polyamide
• Membrane Active Area: 400 ft² (37.2 m²)
• Feed Spacer: 34 mil (0.86 mm)
• Packaging: All membrane elements are supplied with a brine seal, interconnector, and O-rings. Elements are enclosed in a sealed polyethylene bag containing less than 1.0% sodium meta-bisulfite solution, and then packaged in a cardboard box.

Specified Performance

• Low Pressure Performance:
  • Permeate Flow: 6,000 gpd (22.7 m³/d)
  • Salt Rejection: 99.6% (99.4% minimum)
  • Applied Pressure: 600 psi (4.1 MPa)
• High Flow Performance:
  • Permeate Flow: 12,000 gpd (45.4 m³/d)
  • Salt Rejection: 99.8% (99.7% minimum)
  • Applied Pressure: 800 psi (5.5 MPa)

Test Conditions (for Specified Performance):

• 32000 ppm NaCl solution
• 600 psig (4.1 MPa) Applied Pressure (relevant to the low pressure performance)
• 77 °F (25 °C) Operating Temperature
• 10% Permeate Recovery
• 6.5 - 7.0 pH Range

Note: Permeate flow for individual elements may vary +25 / -20 percent from the value specified. Performance is based on data taken after a minimum of 10 minutes of operation and normalized to standard conditions.
