Abstract
A unit for the treatment of water by ozonization including, on the one hand at least one apparatus for the production of ozonized white water and, on the other hand, at least one contactor in a way that the mixing of the water to be treated and the white water occurs in said contactor. The installation for the production of ozonized white water includes a device for dissolution of ozone under pressure in a carrier liquid. In a first embodiment, allowing the treatment of high flows, a portion (typically 5 to 15%) of the main flow of the fluid to be treated is diverted to the vessel for the production of ozonized white water according to the invention, then reintroduced into the main flow within a contactor allowing the whole flow to be treated. In a second embodiment, corresponding more to the treatment of comparatively lower flows, the total flow of fluid is treated directly in the vessel for the production of ozonized white water.
