Membrane processes are important in water purification and treatment. Micro-, ultra- and nanofiltration as well as reverse osmosis have established themselves as alternatives to conventional separation processes in water purification and are now regarded as key technologies also for water cycle closure and recycling.
Oxidative and reductive processes aim at the conversion of critical substances. By the means of chemical reactions, these substances are transformed into less critical substances and, in some cases, permanently immobilized. Due to the large number of different substances usually present in processes, waste and groundwater, the selectivity of oxidative and reductive processes is of great importance in order to enable a targeted degradation in water.
In addition to filtration, adsorption plays an important role in water purification and treatment. Water pollution with organic, endocrine and persistent substances (e. g. drugs and their metabolites) is of particular concern.
In addition to the main topics, the MachWas funding measure supports material developments on the following topics:
The goal of the network and transfer project MachWasPlus is to provide expert support and intensive networking possibilities for the research projects of the funding measure. A further goal is the preparation of the MachWas results for users in the fields of water treatment, wastewater treatment, water utilisation efficiency and groundwater protection/remediation.
