Flow electrodes may enable large-scale sea water desalination Scientists from South Korea have modified a water treatment method called capacitive deionization, with the aim of desalinizing sea water on a large scale. Capacitive deionization uses an electric field to remove cations and anions from water flowing past two oppositely placed electrodes. mark for My Articles similar articles
