Abstract

In this paper, the application and optimization of capacitive deionization technology in seawater desalination is studied. First, the limitations of the traditional desalination technology are reviewed, and the advantages of capacitive deionization technology are introduced. Then, the basic principles of capacitive deionization technology, including electric field effect and processes such as ion migration and charge adsorption, are introduced in detail. In terms of key components, the capacitor (electrolytic cell), electrolyte solution, power supply and control system are highlighted. Then, the optimization methods of capacitor deionization technology are discussed, including the selection and improvement of electrode materials, the optimization of electrolyte solution and the optimization of operating parameters. Finally, the optimization results and effects are analyzed, including improved removal rate and desalination effect, improved energy efficiency, increased water flux and water production capacity, extended maintenance intervals and improved stability, and improved cost effectiveness. This study has important implications for the application and optimization of capacitive deionization technology in seawater desalination.
