Abstract
La présente invention concerne un procédé pour produire des microbulles dans un gicleur d'eau à dispersion destiné à être utilisé dans un processus de flottation utilisant de l'air dissous, et dans lequel un flux d'eau, contenant un gaz tel que l'air, CO¿2?, N¿2?, O¿2? ou similaire dissous sous pression et introduit dans le gicleur, subit un traitement. L'étranglement de ce gicleur d'eau à dispersion a au moins deux sections. L'invention concerne également un appareil pour mettre en oeuvre le procédé.
