An apparatus for the dissolution of ozone in a fluid such as water, for its treatment by the ozone, by injection in said fluid of ozonic air or ozonic gas, including at least one tube placed vertically in a vertical tubular enclosure and communicating with this enclosure via its lower end and via its upper end with means for supplying the fluid to be treated and the ozonic air or ozonic gas. Said vertical tubular enclosure is closed at both its ends and provided with means for the discharge of the fluid treated and of the ozonic air or gas in excess, characterized in that it is provided with means for the injection of hydrogen peroxide so as to complete the oxidation reaction through a radical route.

Apparatus for the disolution of ozone in a fluid

An apparatus for dissolving ozone in a fluid includes a vertically extending closed chamber, and at least one tube extending vertically into the chamber and having a lower end opening into the chamber. Fluid to be treated and ozonized gas is introduced into the upper end of the tube, such that the fluid and gas pass downwardly through the tube, are discharged from the lower end of the tube into a lower end of the chamber, and then passed upwardly through the chamber, whereby ozone dissolves in the fluid. Structures are provided at the upper end of the chamber for discharging fluid having dissolved therein the ozone and excess gas.
