Filmtec (NF90-2540) NANO Filtration Membrane 700 GPD 2.5"X40"
Filmtec NF90-2540 Technical Data
| Model Number | NF90-2540 |
| Dimensions | 2.5" x 40" |
| Permeate Flow Rate | 680-700 GPD (2.6 m³/d) |
| Active Surface Area | 28 ft² (2.6 m²) |
| Salt Rejection Rate | >97% (MgSO₄) |
| Operating Pressure | 70 psi (4.8 bar) |
| Test Conditions | 2000 ppm MgSO₄, 77°F, 15% recovery |
| Application Class | Commercial Nanofiltration |
Membrane Installation Protocol
- Inspect the membrane element for shipping damage and verify the brine seal is intact and properly seated before installation into a 2.5" commercial housing.
- Insert the NF90-2540 element into the pressure vessel with the feed direction matching system flow, ensuring the brine seal engages fully with the housing endcap.
- Flush the system at low pressure (25-30 psi) for 30-60 minutes to remove preservatives, then gradually increase to operating pressure while monitoring permeate TDS.
- Adjust system recovery rate to 15% or lower as specified for optimal rejection performance and membrane longevity in your specific water chemistry.
- Monitor differential pressure across the element and schedule cleaning when pressure drop increases by 10-15% over baseline readings.
System Requirements
The Filmtec NF90-2540 membrane fits standard 2.5" x 40" commercial pressure vessels and is designed for systems treating municipal or well water containing pesticides, herbicides, THM precursors, and moderate hardness. This nanofiltration element operates at significantly lower pressures than brackish RO membranes, making it ideal for applications where organic compound removal is required without complete demineralization. Compatible with most commercial NF system configurations rated for 70 psi operating pressure and 680-700 GPD capacity. Individual element flow rates may vary -20% to +30% from nominal specifications based on actual feed water conditions and system design.
