General Information
TaFlux NF90 series TFNF90-8040-34PRO nanofiltration membrane elements offer molecular weight cut-off (MWCO) of 90 Da for precision separation, enabling tailored selectivity for divalent ion retention, organic molecule fractionation, or monovalent salt permeation.
Operating at 50-80% lower pressure than traditional RO systems, these membranes achieve energy-efficient separation with minimal operational costs and lower lifecycle cost.

Standard test conditions:
The above performance is initial (data record after 30 minutes of operation), based on the following conditions:
2,000 ppm MgSO4
70 psi (4.8 bar) operating press ure
25°C (77°F) operating temperature
15% permeate recovery
*Permeate flow for individual elements may vary but will be no more than ±15%.
**Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending on feed water characteristics and operating conditions.
Element Dimensions
* Each 8040 membrane element supplied with one interconnector (coupler) with four O-rings.
All 8040 elements fit nominal 8.0 inch (203.2 mm) I.D. pressure vessels.
