Department Process Engineering

Process Engineering

The research focus of the Process Engineering Department (ENG) ranges from current and future wastewater and drinking water treatment problems, as well as water pollution control and resource reuse. Our long-term goal is to develop sustainable concepts of the water and nutrient cycle in residential areas.

Currently, the first Swiss wastewater treatment plants are being upgraded with an additional treatment stage for the removal of micropollutants using granulated activated carbon (GAC), including the WWTP at Muri. Eawag provided technical support for the design of the installation and is also investigating unresolved issues.
