LFC3-LD-4040

Summary

Product identification

• Membrane Element: LFC3-LD-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

• Permeate Flow: 2,100 gpd (7.95 m³/d)
• Salt Rejection: 99.7% (99.5% minimum)

Performance is based on the following test conditions (initial data taken after 30 minutes of operation):

• 1500 PPM NaCl solution
• 225 psi (1.55 MPa) Applied Pressure
• 77 °F (25 °C) Operating Temperature
• 15% Permeate Recovery
• 6.5 - 7.0 pH Range

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

Operating limits

• 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 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
• Maximum Pressure Drop for Each Element: 15 psi

Note: The limitations shown are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane.

Mechanical / hydraulic

Dimensions:

• Core tube extension = 1.05" (26.7 mm)
• 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.
