Membrane element/membrane component

Reel type nanofiltration membrane assembly

In the process of separation, nanofiltration membrane has no chemical reaction, no heating, no destruction of biological activity, no change of flavor and aroma, with many advantages such as low pressure energy saving, has been widely used in the preparation of drinking water and food, medicine, biology and other industries. Feymer membrane focusing on special physical purification, fine salt, organic matter removal, zero emissions, and the livelihood of the people drinking water, process water, and other areas of the application, research and development success NF225 selective nanofiltration membrane element, to divalent ions and above, more than 200 molecular weight of organic matters, such as virus has a high removal rate, and sodium, potassium and other monovalent ions through the performance.
 
Design characteristics of Feymer NF membrane element

  • ●High selectivity for Ion transmission, strong anti-pollution ability;
  • ●The separation process has no phase transition and does not destroy biological activity;
  • ●Membrane component specification standardization, installation/replacement simple operation;
  • ●The operating pressure is lower than reverse osmosis, which has the advantage of low-voltage energy saving;
  • ●The system is highly integrated, fully automated and easy to operate.

Remark:

  1. NF225:High selective desalting, for bivalent and more ions, molecular weight of more than 200 organic matter, has a high removal rate, and the univalent ion transmittance performance is excellent.
  2. NFR series:The high desalination rate has a good removal rate for pesticides, herbicides, TOC and transition metals.
  3. NFH series:The high degree of high price desalination rate and the medium degree of monovalent desalination rate are suitable for the field of valuable material recovery and the salt content in the water produced is not too high requirement.

Applications of NF membranes

    • ●Special substances are separated and purified
    • ●Fine salt separation
    • ●Chemical wastewater treatment
    • ●Zero waste water discharge
    • ●Organic matter removal
    • ●Municipal Drinking Water Treatment
