On 9.7.24, the innovatION project partners met at the District Association for Water Management in Nienburg an der Weser. Here they discussed the latest news on the membrane and electrode materials and evaluated the results from the laboratory and the pilot plants. Thanks to the digital head start, a lot of data was collected on Langeoog as well as in Nienburg, which shows that monovalent ion selective membrane capacitive deionization can desalinate brackish water in a stable manner. Cleaning of the system has hardly been necessary to date, which speaks for the sustainability of the process. Only the longevity and electrodes still need to be optimized.
Following the evaluation of the results and further planning in the innovatION joint project, the project partners then went to the pilot plant in Nienburg. Here, modified membranes from the collaboration between FUMATECH BWT GmbH and Leibniz-Institut for Polymer Research Dresden e. V. will be used to selectively remove nitrate from the groundwater until the end of August.
