Abstract

Cette invention concerne un réacteur, un système et un procédé d'oxydation qui font appel à un générateur à bulles fines pour transférer de l'oxygène à fort débit de manière à transformer sels aqueux en leurs formes oxydées. Un agitateur-mélangeur répartit les fines bulles dans la solution aqueuse. En réagissant avec l'oxygène, le sel réduit s'oxyde. On pourra éventuellement recourir à une rondelle pour empêcher le dépôt de solides tels qu'un sel sulfaté précipité ou du tartre de se déposer sur le générateur de fines bulles et faciliter le retrait de tels solides qui se sont formés sur le générateur. Le réacteur, système et procédé d'oxydation peuvent être utilisés en continu ou en discontinu.
