Summary
Product Identification
- Model: ESPA1
- Configuration: Spiral Wound
- Membrane Polymer: Composite Polyamide
- Membrane Active Area: 400 ft² (37.2 m²)
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.
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 +25 / -15 percent from the value specified.
- Permeate Flow: 12,000 gpd (45.4 m³/d)
- Salt Rejection: 99.4% (99.2% minimum)
Test Conditions:
- NaCl Solution: 1500 ppm
- Applied Pressure: 150 psig (1.03 MPa)
- Operating Temperature: 77 °F (25 °C)
- Permeate Recovery: 15%
- pH Range: 6.5 - 7.0
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.
- Maximum Applied Pressure: 600 psig (4.14 MPa)
- Maximum Chlorine Concentration: < 0.1 ppm
- Maximum Operating Temperature: 113 °F (45 °C)
- pH Range, Continuous (Cleaning): 2-10 (1-12)
- Maximum Feed Flow: 75 gpm (17.0 m³/h)
- Minimum Brine Flow: 12 gpm (2.7 m³/h)
- Maximum Pressure Drop for Each Element: 15 psi (0.10 MPa)
