The interest in efficient desalination processes is increasing due to the globally increasing water demand and decreasing available freshwater resources. Groundwater that is affected by seawater or by geogenic salt deposits often show increased concentrations of sodium and chloride. Whereby, high nitrate and sulphate concentrations originate mainly from agricultural use. A complete desalination of water is usually not required, since only a reduction of the monovalent ions is necessary.
The aim of the innovatION research project is the development of an energy-efficient, selective, membrane based electrochemical desalination process (mMCDI) on the basis of Membrane Capacitive Deionisation focused on the removal of monovalent ions from saline groundwater and surface water. Thereby, potential applications and uses for this desalination process should be examined by considering water-chemical, economic and ecological aspects.
The Chair of Process Engineering in Hydro Systems (project coordinator) and the Chair of Business Management, esp. Sustainability Management and Environmental Accounting at Technische Universität Dresden are investigating the selective retention of water constituents as well as the energy efficiency and sustainability of the desalination process.
By choosing the following partners from industry, science and practice, the consortium is able to build, test and evaluate our innovative desalination technology:
-
Chair of Process Engineering in Hydro Systems of the Technische Universität Dresden
-
Working group Hydrogeology and Landscape Hydrology of the Carl von Ossietzky Universität Oldenburg
-
Working group Polymeric Membrane Materials of the Leibniz-Institut für Polymerforschung Dresden e.V.
-
elkoplan staiger GmbH – Automation für die Umwelt- und Verfahrenstechnik
-
KWR Water Research Institute (international associate partner)
-
United Nations University, Inst. for Integrated Management and Material Fluxes and of Resources (international associate Partner)
The results of this project contribute significantly to secure water resources – nationally and internationally. Further information about the BMBF funding measure and the project management agency are listet below:
