Abstract

La présente invention concerne un dispositif et un procédé de traitement de milieux liquides mettant en œuvre une enceinte (10) adaptée pour recevoir un milieu liquide (100) contenant des particules polluantes (120), un moyen (30) configuré pour introduire une séquence de bulles (40) dans le milieu liquide (100) et un élément de collecte (12, 14, 50, 60, 62) situé au moins partiellement au-dessus du niveau supérieur du milieu liquide (100) pour recevoir les particules polluantes (120) projetées à l'extérieur du milieu liquide (100) par l'interaction des bulles (40).
