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.
Product Specifications
E-MEM? Element | Active Area | Feed spacer Thickness（mil） | Permeate Flow GPD （m3/d） | Salt Rejection （%） |

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.

1. Refer to the design guidelines for E-MEM when designing multi-component systems。1 inch=25.4 mm
2. The components are fitted with pressure vessels with nominal inner diameter of 8 inches (203 mm).
Operating limit
Maximum operating temperature | 113℉（45℃） |
Maximum operating pressure | 600 psig（41 bar） |
Maximum pressure drop | 15 psig（1.0 bar） |
pH range, continuous operation | 3-10 |

a When pH > 10, the maximum allowable temperature for continuous operation is 95 ℉ (35 ℃).
b For more information, please refer to the "Cleaning Steps" in the E-MEM Guidance Manual.。?
c Under certain conditions, the presence of free chlorine and other oxidants will lead to premature failure of membranes. Therefore, it is recommended that the membrane be pretreated to remove residual free chlorine before water comes into contact with membranes.
