FAQ
  • What is better taste water?
    For better taste, the water should have small molecular clusters; The hardness is between 50-150mg / L with balanced mineral composition consisting of calcium, potassium, silicate ions, but free from odor caused by disinfectant residual products and other organic matters.
  • Is there any cost effective advantage compared with RO?

    Nanofiltration is 30-100% more expensive than RO in current market.

    We have been trying to control the cost so that consumers can accept hollow fiber nanofiltration .

    We have the whole integrated production line from upstream raw materials to membrane modules, which allows us to have a better control in cost and high value vs. performance products.

  • Can all harmful substances be removed by nanofiltration?

    According to current data, nanofiltration has a good effect on removing the most concerned harmful substances in the water, such as heavy metals, endocrine disruptors, colour , antibiotics, hormone etc.

  • Other features or advantages?

    1.   Through the copper sulfate experiment, it has a good effect on removing heavy metal copper ions. The produced water meets the limits required by NSF58.

    2.   pH experiment shows that the water produced by NÜF is very similar to feed (even more alkaline), which is like the bottled mineral water on the market.

    3.   We are in NSF applying processing. We passed MOH testing ( Chinese Healthy drinking approval).

  • Salt Rejection rate of NÜF ?
    MgSO4 91%，CaCl2 65%，NaCl 15%
  • What is the operational temperature tolerance of hollow fiber NÜF ?

    45 Celsius （113 Fahrenheits)
