Nanofiltration

Nanofiltration

The characteristic of nano membranes is that the rejection of monovalent and divalent ions present in water is different.

It allows for selective removal. Their main applications include the recovery of special chemicals, such as developers, dyes, etc., and expensive raw materials, and the removal of some of the monovalent ions while significantly reducing the concentration of divalent ions in seawater desalination plants.
