Water technologies and resource recovery

This innovation field develops concepts, processes and technologies for purifying water and recovering valuable substances from water.

Hygiene in drinking and process water and the associated water analysis play an important role in this.

For water management, the innovation field develops comprehensive concepts, e.g. within the framework of the Morgenstadt City Lab. One focus is on international cooperation to develop and adapt solutions for emerging countries (e.g. South Africa, India, Brazil).

Our activities within this innovation field are not limited to the topic of water. As part of system solutions, we are developing technologies for the use of organic and recycling inorganic (waste) materials. In particular, we treat organic residues such as organic waste or sewage sludge anaerobically in order to economically produce biogas as a regenerative energy source.

We also use the electro-oxidative and reductive processes developed for water treatment in the electrochemical production of basic chemicals from aqueous solutions.

Water and wastewater treatment for industry and municipalities

Water treatment is now confronted with new challenges. The pollution of the past has a direct impact today on the natural sources of water, surface waters and groundwater. Insufficiently treated process wastewater that is discharged into bodies of water results in long-term damage that then has to be tackled later on at great expense. The pollution of rivers, lakes and groundwater with pesticides, mineral oil residues or pharmaceuticals are examples of this.
