Fortilife XC-N

Summary

Product identification

The FilmTec™ Fortilife™ XC-N Element is a spiral-wound element featuring a polypiperazine thin-film composite membrane. It is designed for industrial applications facing difficult water challenges, such as wastewater reuse and Minimal Liquid Discharge (MLD).

Key benefits include:

• Selective and high monovalent ion passage with high divalent ion and Chemical Oxygen Demand (COD) rejection, facilitating the production of high purity salt solution in permeate while reducing concentrate waste.
• High permeability membrane chemistry for increased water recovery and/or low energy operation.
• Robust membrane and reliable long-term performance.

Performance

• Active Area:
  • 365 ft²
  • 34 m²
  • Active area is guaranteed ± 3%.
• Feed Spacer Thickness: 34 mil
• Target Permeate Flow Rate:
  • 8,375 GPD
  • 31 m³/d
• Stabilized Salt Rejection: 99.0%
• Minimum Salt Rejection: 98.0%

Performance is based on standard test conditions: 2,000 ppm MgSO₄, 70 psi (0.48 MPa), 77°F (25°C), 15% recovery. Flow rates for individual elements may vary by no more than ± 20%.
