SWC4-plus

Summary

Product identification

• Membrane Element: SWC4+
• Configuration Type: Spiral Wound
• Membrane Polymer: Composite Polyamide
• Nominal Membrane Area: 400 ft²

Performance

• Permeate Flow: 6,500 gpd (24.6 m³/d)
• Nominal Rejection: 99.8 %
• Minimum Rejection: 99.7 %

Performance is initial (data taken after 30 minutes of operation), based on the following conditions:

• 32,000 ppm NaCl
• 800 psi (5.5 MPa) Applied Pressure
• 77 °F (25 °C) Operating Temperature
• 10% Permeate Recovery
• 6.5 - 7.0 pH Range

Operating limits

• Maximum Applied Pressure: 1200 psig (8.27 MPa)
• Maximum Chlorine Concentration: < 0.1 PPM
• Maximum Operating Temperature: 113 °F (45 °C)
• Feedwater pH Range: 3.0 - 10.0
• Maximum Feedwater Turbidity: 1.0 NTU
• Maximum Feedwater SDI (15 mins): 5.0
• Maximum Feed Flow: 75 GPM (17.0 m³/h)
• Minimum Ratio of Concentrate to Permeate Flow for any Element: 5:1
• Maximum Pressure Drop for Each Element: 10 psi

The limitations shown are for general use; values may be more conservative for specific projects.

Mechanical / hydraulic

• A (length): 40.0 inches (1016 mm)
• B (diameter): 7.95 inches (201.9 mm)
• C (interconnector ID): 1.125 inches (28.6 mm)
• Weight: 36 lbs. (16.4 kg)

Packaging

All membrane elements are supplied with a brine seal, interconnector, and o-rings. Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite solution, and then packaged in a cardboard box. Permeate flow for individual elements may vary ± 15 percent.
