    Feature

              

    With breakthroughs in membrane materials and element structure, Ochemate Advanced Material Technologies Co. Offers NÜF® N90 

    membrane elements with hollow fiber structure for industrial and municipal application. NÜF®  N90 has high permeability under low

    pressure and provides unique comprehensive advantages for industrial and municipal users.

    • High hardness removal, high efficient toxic metals removal such as copper, cadmium, chromium, lead, mercury, antimony and arsenic.
    • High small organic molecule removal (such as antibiotics, endocrine disruptor, etc.) and reduce COD in water.
    • High removal rate for monovalent salt.

    Hollow fiber nanofiltration membrane NÜF® N90 element can effectively remove impurities from water in commercial applications:

    harmful substances such as colloids, bacteria, viruses, and organic matter retain beneficial minerals and trace elements. It can be widely used for drinking water in commercial office buildings, canteens and catering institutions, hotels and clubs, hospitals and schools, airports and stations, and other public places. It can achieve a balance between safety and health in drinking water purification technology - creating "better drinking water, healthier membranes".

    NÜF® N90 element has the typical characteristics of all NÜF® product series:
    • Unique hollow fiber structure.
    • high anti-fouling capacity
    • Low operating pressure, high permeate flux.

    General Information


    • At the first use, it is suggested that rinse the protective agent from NÜF® membrane through connecting water for one hour. Please discharge the permeate water from this one hour.

    • Membrane elements should always be kept moist after initial use.

    • Membrane elements have a short-term resistance to free chlorine and other oxidants. Long-term contact may lead to damage of membrane fibers. Continuous exposure of membrane components to free chlorine or other oxidants should be avoided.
    • Back pressure on the permeate side should be avoided at all times.
