Title
(EN) SYSTEM AND METHOD FOR DISSOLVING GASES IN FLUIDS AND FOR DELIVERY OF DISSOLVED GASES
(FR) SYSTEME ET PROCEDE POUR LA DISSOLUTION DE GAZ DANS DES FLUIDES ET POUR LA DISTRIBUTION DE GAZ DISSOUS
Abstract
(EN)
Apparatus and methods are disclosed for facilitating dissolution of one or more gases into a liquid. Preferred gases for use with the apparatus are oxygen, air, and ozone. An apparatus of the present invention comprises a dissolution tank that includes a pressure vessel, at least one liquid spray nozzle, and a fluid outlet. The apparatus also comprises a gas source, means for passing fluid into the pressure vessel, and a discharge device connected to the fluid outlet, which discharge device is provided with at least one orifice. Preferred applications include wastewater treatment, treatment of drinking water, fermentation, and bioremediation.

Dispositifs et procédés pour faciliter la dissolution d'un ou plusieurs gaz dans un liquide Gaz préférés : oxygène, air et ozone. On décrit un dispositif qui comprend un réservoir de dissolution à récipient de pression, au moins une buse de pulvérisation de liquide et une sortie de fluide. Le dispositif comprend aussi une source de gaz, un système de transfert de liquide dans le récipient de pression et un dispositif d'évacuation relié à la sortie de fluide, le dispositif d'évacuation comportant au moins un orifice. Applications préférées : traitement des eaux usées, traitement de l'eau potable, fermentation et biorémédiation.
