Title
(EN) SOLID BUOYANT MEDIA INDUCED FLOTATION
(FR) FLOTTAISON PAR MILIEUX FLOTTANTS SOLIDES
Abstract
(EN) A clarification system for fluids in which particles are separated from the fluid by flotation and in which the buoyant media inducing the flotation is recycled. Flotation can be assisted by a flotation assistance device, such as dissolved air flotation.
(FR) Cette invention concerne un système de clarification pour liquides dans lequel la séparation des particules présentes dans le liquide s'opère par flottaison et où le milieu flottant qui produit la flottaison est recyclé. La flottaison peut être facilitée par l'emploi d'un dispositif d'assistance sous forme de système de flottaison à air dissous.
