Why water quality modelling? Torsten Strube KompetenzZentrum Wasser Berlin www.kompetenz-wasser.de 1 What is the KWB? • Foundation of KWB as non profit research network organisation in Berlin in 2001 • Partial privatisation contract of Berliner Wasserbetriebe – agreement on financial support for the Berlin water research community by Veolia Water www.kompetenz-wasser.de Aims of KWB • Promotion of research and development in Water resource management and technology – Sustainable water management – Groundwater management – Water and wastewater technology www.kompetenz-wasser.de Mission and activities • Initiation, preparation and realisation of research projects • Exploitation of know-how • Network management, public relations • International conferences and symposia, training www.kompetenz-wasser.de Research in the urban water cycle Three main issues: Surface Water www.kompetenz-wasser.de Ground Water Waste water Research in the urban water PHARMA-Treat cycle Treatment of medical sewage in hospitals VOLAMOD Diffusion of pollutions by accidents Foundation for professorship Civil engineering ISM/EVA Rainwater management OLIGO ODOCO Restoration of water bodies Corrosion in sewage systems CYLIN SCST Algae toxins in water bodies New sanitary systems ENREM TRACE Nutrients removal through membrane bioreactors Persistent pollutants AQUISAFE Mitigation of contaminants NOSTOTOX Occurence of invasive algae www.kompetenz-wasser.de TECHNEAU AMEDEUS Drinking water technology MBR-TechnologyNetwork NASRI/IDB-India MBR-Train Bank filtration Young scientist training Research in the urban water PHARMA-Treat cycle Treatment of medical sewage in hospitals VOLAMOD Diffusion of pollutions by accidents Foundation for professorship Civil engineering ISM/EVA Rainwater management OLIGO ODOCO Restoration of water bodies Corrosion in sewage systems CYLIN SCST Algae toxins in water bodies New sanitary systems ENREM TRACE Nutrients removal through membrane bioreactors Persistent pollutants AQUISAFE Mitigation of contaminants NOSTOTOX Occurence of invasive algae www.kompetenz-wasser.de TECHNEAU AMEDEUS Drinking water technology MBR-TechnologyNetwork NASRI/IDB-India MBR-Train Bank filtration Young scientist training Research in the urban water cycle Modelling very important part of these projects Decision support for management options www.kompetenz-wasser.de Why water quality modelling? • Surface water for drinking water supply • If there is any pollution the water has to be treated! – Eutrophication – Trace contaminants etc. www.kompetenz-wasser.de Why water quality modelling? • EU Water framework • Global change: directive: – higher temperature, – Quality aspects – Origin of nutrients www.kompetenz-wasser.de – Higher/ lower nutrients entry, – more/ less storm events Why water quality modelling? • EU Water framework • Global change: directive: – higher temperature, – Quality aspects – Origin of nutrients •The water supplier needs to know: –What has to be expected? –Which measures are necessary to handle the problem? www.kompetenz-wasser.de – Higher/ lower nutrients entry, – more/ less storm events Aquisafe project • Mitigation of contaminants in rural/semi rural environments • Design and operation of mitigation zones at the UBA’s experimental field • Identification of the most effective place to establish mitigation zones www.kompetenz-wasser.de CYLIN project • Cyanobacterium (blue algae) Cylindrospermopsis raciborskii of tropical origin • Occurrences in lakes of the Berlin area • Production of the cellular toxin Cylindrospermopsin (CYN) • Risk for bathing waters and also for drinking water quality www.kompetenz-wasser.de OH H H O OSO3N HN HN N + CH3 OH H HN CYN cellular active poison, inhibition of protein biosynthesis LD50 2,1 mg/kg Conclusion Why water quality modelling? • Assessing the impacts of climate change • Achieving the Water framework directive • Supporting management options …regarding the water supply of Berlin! www.kompetenz-wasser.de
