Abstract
La présente divulgation concerne un procédé pour traiter et régénérer une solution caustique usée à pression et température ambiantes, le procédé comprenant l'oxydation d'eaux usées caustiques avec un mélange de solution de saumure et d'ozone, assistée par une irradiation par ultrasons des eaux usées caustiques. Diverses techniques de traitement d'eaux usées peuvent en outre être incluses pour atteindre un niveau de qualité d'effluent souhaité.
