ESPA2-8040

Summary

Product identification

• Membrane Element: ESPA2-8040
• Type: Spiral Wound
• Membrane Polymer: Composite Polyamide
• Membrane Active Area: 400 ft² (37.1 m²)

Performance Data (Test Conditions)

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

• 1500 PPM NaCl solution
• 150 psi (1.05 MPa) Applied Pressure
• 77 °F (25 °C) Operating Temperature
• 15% Permeate Recovery
• 6.5 - 7.0 pH Range

Performance:

• Permeate Flow: 9,000 gpd (34.1 m³/d)
• Salt Rejection: 99.6 % (99.5 % minimum)

Note: Permeate flow for individual elements may vary ± 15 percent. Membrane active area may vary ± 4%.

Operating limits

• Maximum Applied Pressure: 600 psig (4.16 MPa)
• Maximum Chlorine Concentration: < 0.1 PPM
• Maximum Operating Temperature: 113 °F (45 °C)
• pH Range, Continuous (Cleaning): 2-10.6 (1-12)*
  • *The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane.
• 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

Mechanical / Hydraulic

• A: 40.0 inches (1016 mm)
• B: 7.89 inches (200 mm)
• C: 1.125 inches (28.6 mm)
• Weight: 36 lbs. (16.4 kg)

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.
