Membrane technology can be a flexible and viable long-term strategy for water treatment. However, prosperous and effective application of membrane technology has been hampered by membrane fouling induced by a wide spectrum of components in water. Particularly, dissolved natural organic matter (DNOM), a major organic constituent in surface water, has been considered to be a significant foulant, strongly reducing the membranes performance especially for NF (nanofiltration) membranes.
Furthermore, It is well known that membrane fouling by DNOM is significantly enhanced in the presence of divalent cations (e.g. Ca2+). Despite much research and industrial developments since the early 1960’s, membrane fouling and especially irreversible fouling remains challenging and in-depth studies on mechanisms and solutions for irreversible fouling of inorganic membranes are lacking.
We have developed a smart surface functionalization method to decrease the fouling tendency by preventing the undesired adsorption or adhesion of foulants...
