ESPA2-LD-MAX

Summary

Product Identification

• Product Name: ESPA2-LD MAX
• Configuration: Low Fouling Spiral Wound
• Membrane Polymer: Composite Polyamide

Specified Performance

The Specified Performance is based on data taken after a minimum of 10 minutes of operation. Actual testing of elements may be done at conditions which vary from these exact values; in which case, the performance is normalized back to these standard conditions. Permeate flow for individual elements may vary ±15 percent from the value specified.

• Permeate Flow: 12,000 gpd (45.4 m³/d)
• Salt Rejection: 99.6% (99.5% minimum)
• Test Conditions:
  • 1500 ppm NaCl solution
  • 150 psig (1.03 MPa) Applied Pressure
  • 77 °F (25 °C) Operating Temperature
  • 15% Permeate Recovery
  • 6.5 - 7.0 pH Range

General Product Description

Values listed are indicative, not specified.

• Membrane Active Area: 440 ft² (40.9 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.

Mechanical / Hydraulic

Element details are indicative, not specified.

• A: 40.0 inches (1016 mm)
• B: 7.89 inches (200 mm)
• C: 1.125 inches (28.6 mm)

Operating Limits

The limitations shown here are for general use. For specified projects, operation at more conservative values may ensure the best performance and longest life of the membrane.
