Engineering summary from PDF text extraction for ESPA2-LD-4040. Verify every value with the OEM datasheet.

Summary

Product identification

  • Membrane Element: ESPA2-4040 (Low Fouling Technology)
  • Type: Low Fouling Spiral Wound
  • Membrane Polymer: Composite Polyamide
  • Membrane Active Area: 80 ft² (7.43 m²)
  • Feed Spacer: 34 mil (0.864 mm) with biostatic agent

Performance

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

  • Salt Rejection: 99.6 % (99.4 % minimum)

Note: Permeate flow for individual elements may vary +25 or - 15 percent.

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): 2-11 (1-13)
  • Maximum Pressure Drop for Each Element: 10 psi

Feed water

  • Maximum Feedwater Turbidity: 1.0 NTU
  • Maximum Feedwater SDI (15 mins): 5.0
  • Maximum Feed Flow: 16 GPM (3.6 m³/h)
  • Minimum Ratio of Concentrate to Permeate Flow for any Element: 5:1

Mechanical / hydraulic

  • A: 40.0 inches (1016 mm)
  • B: 3.95 inches (100.3 mm)
  • C: 0.75 inches (19.1 mm)
  • Weight: 8 lbs. (3.6 kg)
  • Core tube extension: 1.05 inches (26.7 mm)

Packaging and Guarantees

  • 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.
  • All elements are guaranteed 99.4% minimum rejection.
