Title: | Flow-electrode capacitive deionization mechanisms, electrodes development, cell designs and operation performance in various condition | Authors: | Nguyen Dang Minh Huan | Keywords: | Flow-electrode capacitive deionization;Electrodes development;Cell designs | Issue Date: | 2023 | Abstract: | The Flow-electrode Capacitive Deionization (FCDI) system is considered to be a new potential advancement and is more efficient than earlier Capacitive Deionization (CDI) and Capacitive Deionization (MCDI) systems in addressing brackish water and freshwater demand issues in salty locations. The report will dig into detail regarding the FCDI cell's architecture in this research, as well as methods to manage the pumping system to obtain the best desalination performance possible. Applying the capacitive adsorption property and providing voltage at both ends of the electrode, salt ions will migrate and adhere to the surface of the matching electrode. Furthermore, the electrode will be cycled through the system to replace it continually throughout the operating process. Experiment findings show that with a modest beginning salt content (from 1g/L NaCl to 5g/L NaCl), 5% grams of salt may be eliminated from the solution after just 15 minutes of operation. In addition, variation in voltage also have certain effects on the desalination ability of the FCDI system. There is a clear difference with 1.1V voltage applied at the two polars of the cell only an average of 28.33mg of salt is removed, whereas with 1.5V an average of 45mg of salt is removed. This is an excellent result when compared to previous research publications using the same FCDI method, given that the major components of the electrode in this study are: water, salt, and activated carbon |
