WATER SYSTEMS ENGINEERING

Engineering the molecule of life

The group “Water Systems Engineering“, led by Dr. Karl Glas, is focusing on the interface of water, energy and environment with a special emphasis on the needs of the beverage and food industry. Within this highly complex context, a wide spectrum of specific issues (drinking water, waste water, process engineering, microbiology, water as food, sensory) is studied in various research projects. These investigate subjects like the management of energy or material processes and specific issues of microbiological or industrial hygiene. Theoretical as well as technical solutions ensure the maximization of energy and resource efficiency of single process steps or complex process chains and provide alternatives for established processes while minimizing the impact on the environment. Sophisticated methods are used for the simulation of chemical-physical processes, for the analysis of novel materials, and for the modelling of composite facilities and multi-parametric process structures. The group organizes the annual seminar series “Weihenstephaner Seminar für Wassertechnologie” (see HERE).
