Abstract
Method for bringing ozone into contact with a flow of liquid in which a fraction of the liquid flow is tapped off, a carrier gas laden with ozone is injected into the tapped-off flow, forming gas bubbles, the gas bubbles and the liquid are mixed so as to form a two-phase tapped-off flow, and the tapped-off flow is reintroduced into a descending vertical stream of the main liquid flow, this vertical stream undergoing, at the bottom, a change of direction to essentially the horizontal, the reintroduction of the tapped-off flow being carried out at the lower end of an injection tube immersed in the descending vertical stream of the main flow. The descending vertical stream () forms a continuous liquid column, static mixing is provided in the injection tube () as far as the vicinity of its outlet, and the two-phase tapped-off flow is reintroduced into the descending vertical stream () in the form of at least one jet having a vertically downward velocity component, this reintroduction taking place below a height (H) of liquid and with a vertically downward velocity component that are sufficient for the gas bubbles to be entrained downwards, without rising.
