A unit for treating water by ozonation, including at least one ozonised white water production apparatus and at least one contactor for mixing water to be treated and white water. The ozonised white water production apparatus includes an assembly for pressure-dissolving ozone in a carrier liquid. In a first embodiment suitable for treating large flows, a fraction (typically 5-15 %) of the main fluid flow to be treated is fed to an ozonised white water production vessel then returned to the main flow within a contactor for treating the entire flow. In a second embodiment more suitable for treating comparatively small flows, the total fluid is directly treated in the ozonised white water production vessel.
