L'introducteur (14) d'eau fournit de l'eau à haute pression introduite par un orifice d'alimentation (12) via un orifice (13) de décharge. La conduite de gaz (16) comporte un orifice d'introduction de gaz (15) donnant dans l'introducteur d'eau (14) et assurant le mélange du gaz éjecté et de l'eau sous haute pression. La tuyère (17) en raison de sa forme divergente produit dans l'espace intérieur un phénomène de cavitation dans le flux d'eau à haute pression sortant de l'orifice de décharge d'alimentation (13). La plaque de collision (18) disposée face à la tuyère (17) à une distance donnée assure la dispersion de l'eau mélangée aux fines bulles d'air
