Membrane Element EM-NF-8040
In the production of NF (Nano-Filtration) products, E-MEM optimizes the membrane material and strictly controls the synthesis process. The developed NF membrane not only remove the macromolecular, divalent and multivalent iron, but also do purification , concentration and separation.
1 With years of proven performance.
2 High performance and long element life.
3 Offers a nanofiltration technology that selectively removes these components,color
4 operates at low operating pressures.
5 ODM and OEM are available.

EM-NF-8040-R85 | 400 （37） | 28 | 7500 （28.4） | 98.0 |
EM-NF-8040-R40 | 400 （37） | 28 | 8000 （30.3） | 95.0 |
1. Permeate flow and salt (MgSO4) rejection based on the following standard test conditions: 500 ppm MgSO4, 70 psi (4.8 bar), 77°F (25°C), pH 7.5, 15% recovery.
2. Flow rates for individual elements may vary but will be no more than 20% below the value shown.
3. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feed water characteristics and operating conditions.
4. Sales specifications may vary as design revisions take place.
