Nanofiltration (NF), as a powerful

Nanofiltration (NF), as a powerful tool for separation of small molecules and salts, has attracted growing
attention in many applications such as wastewater treatment, water purification, desalination, food
processing and bio-separation. It is well known that pH and salt conditions have significant influence on
NF performance. In order to manipulate NF process and optimize its efficiency, it is very important to get
insights into the effects of pH and salt on nanofiltration.
