ESPA-MAX-8040

Summary

Product identification

• Membrane Element: ESPA2 MAX-8040
• Configuration: Spiral Wound
• Membrane Polymer: Composite Polyamide
• Membrane Active Area: 440 ft² (40.8 m²)

Performance

• Permeate Flow: 12,000 gpd (45.4 m³/d)
• Salt Rejection: 99.6 % (99.5 % minimum)
• Boron Rejection (Typical) @ pH = 10: 93.0 % (when tested at standard test conditions with 5.0 ppm Boron in feed solution)
• Permeate flow for individual elements may vary ± 15 percent.
• Membrane active area may vary ± 4%.
• All elements are guaranteed 99.5% minimum rejection.

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)
• Maximum Feedwater Turbidity: 1.0 NTU
