The focus of our department is on water quality of standing and flowing surface waters. Our work includes the detection and assessment of anthropogenic influences, their effect on water quality, and remediation through e.g. treatment of wastewater. Physical, chemical, and biological water quality problems are studied with field and laboratory measurements and experiments, and mathematical models. Water Quality Engineering is one of the main subjects of the study program "Technischer Umweltschutz" (Environmental Science and Technology). Our department encompasses the scientific, analytical, and engineering tasks involved in safeguarding and remediating water quality in the various compartments of the water cycle.
The Department of Water Quality Engineering was established at the Institut für Technischen Umweltschutz in 1978 in connection with the new study program "Technischen Umweltschutz" and Prof. Dr.-Ing. G. Axt was appointed as chair. From 1988 to 2018, Prof. Dr.-Ing. M. Jekel was head of the department. Since 2018 Prof. Dr. F. Hellweger is head of the department. The department was renamed to Water Quality - Science and Engineering in 2023.
