Chemical and physical aspects of natural organic matter (NOM) fouling of nanofiltration membranes
TL;DR: In this paper, the role of chemical and physical interactions in natural organic matter (NOM) fouling of nanofiltration membranes is systematically investigated, and it is demonstrated that the rate of fouling is controlled by an interplay between permeation drag and electrostatic double layer repulsion.

Nanofiltration extends the range of membrane filtration
TL;DR: Nanofiltration is a pressure driven membrane process between reverse osmosis and ultrafiltration for removal of color and TOC from Florida surface water, removal of hardness, radium, and sulfate from well water, and simultaneous removal of sodium chloride and concentration of organics with molecular weight 300–1000 in the food and pharmaceutical industries.
