Kurzbeschreibung (Englisch)
Drinking water reservoirs predominantly guarantee a long-term storage for drinking water supply. The raw water has not only to be provided in adequate amount, but also in a preferably high quality. Normally, drinking water reservoirs are also asked to fulfill additional requirements, as e. g. flood risk management, energy production, and recreational use. Furthermore, according to the European Water Framework, the ecological condition of the downstream of the reservoir has to be taken into consideration when the management of drinking water reservoirs is discussed. Unfortunately, these aspects result in distinctive conflicts of objectives that increasingly influence drinking water treat-ment.
The main objective of this project is the development of a technological model describing conse-quences of varying raw water qualities, resulting from different management strategies, on drinking water treatment. Previous research on treatment of raw water from reservoirs was prior performed by fixing single boundary conditions like the quality of the raw water, the treatment capacity, or the existent technology of treatment.
Therefore, it has to be investigated, how both short-time varying and slowly changing qualities of raw waters from reservoirs can be controlled within the process of drinking water treatment and supply. For that purpose, besides conventional treatment processes, especially efficient processes to remove dissolved organic and particulate compounds will be applied and optimized using varying raw water qualities. Moreover, a novel technique in water treatment (direct nanofiltration of reservoir water) shall be considered in addition. The results of the investigations are aimed at providing the input in a technological model to describe the treatment capacity of different process combinations at given raw water qualities.
Experimental work included lab- and small-scale experiments. One objective of the research project was the optimization of flocculation processes. Therefore, lab-scale experiments to determine optimal coagulants for different raw water qualities needed to be performed. Based upon the results, a small-scale treatment plant including the optimized flocculation process followed by multi-layer filtration, biofiltration, or nanofiltration, respectively, was operated.
