Subproject: Development of mixed-matrix membranes

Mixed-matrix membrane.

Nowadays various types of membranes for water filtration are already available through commercial channels. A common feature of these membranes is that substantially different separation cut-offs are used for size exclusion. On the other hand, the underlying porous structure, which provides a large specific surface, remains unused.

Multifunctional membranes for the separation of micro-pollutants and heavy metals from water

In this project, materials and processes are being developed in order to make full use of the membrane. New coating materials and new particulate additives are being developed for this purpose. These are either integrated directly in the production process or in an after-treatment step into the membrane. This approach makes it possible to obtain membranes which, in addition to their filtration function, can adsorptively bind substances dissolved in water by adsorption.
