Energy-softening Nanofiltration (NF) Series

 

 

  
Introduction
The new coating technology, which applied in all nanofiltration membrane elements, has the advantages of efficient selectivity and filterability in separation processes without any chemical reaction, heating, phase transition, destroying biological natures or lower pressure than RO process. It has been applied in healthy drinking water and separation & concentration and purification process in food, medicine and biology more and more widely.
