Nano Filtration is a pressure driven separation process. The filtration process takes place on a separation layer formed by an organic semi per-meable membrane. The driving force of the separation process is the pressure difference between the feed (retentate) and the filtrate(permeate) side at the separation layer of the membrane. However, because of its selectivity, one or several components of a dissolved mix-ture are retained by the membrane despite of the driving force, while water and substances with a molecular weight less than 200D (daltons) are able to permeate the separation layer. Because nano filtration membranes also have a selectivity for the charge of the dissolved components, monovalent ions will pass the membrane and divalent and multivalent ions will be rejected.
