    With breakthroughs in membrane materials and element structure, Ochemate Advanced Material Technologies Co. Offers NÜF® N80-6040 nanofiltration membrane elements with hollow fiber structure for industrial and municipal application. NÜF® N80-6040 has super-high permeability under extremely 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 removal rate of organic matte, efficient removal for small molecular organic matter (such as antibiotics, endocrine disruptor, etc.) and reduce COD in water.
    • Under 3.0 bar operating pressure, the membrane flux can exceed 30 LMH. Compared with the competitors, N80-6040 has 35% lower operation pressure under the same flux.
    • Outside-in structure of NÜF® N80-6040 makes elements high anti-fouling and easy to clean.
    Hollow fiber nanofiltration membrane NÜF® N80-6040 NF element can efficiently remove hardness and achieve partial desalination for industrial applications. For municipal application, NÜF® N80-6040 NF element can efficiently remove hardness, sulfate, fluoride, heavy metals, small organic molecule and PPCPs to ensure the safety of water supply. Compare with competitors, NÜF® N80-6040 NF element has higher flux, lower energy consumption, high fouling resistance and is easy to clean.
    NÜF® N80-6040 NF element has the typical characteristics of all NÜF® product series:
    • Unique hollow fiber structure.
    • Low operating pressure, high permeate flux.
    Product Types
