Abstract

An installation for the treatment of a flow of liquids, notably potable water or effluents, installation of the type wherein the liquids are put into contact with a treatment gas during a pre-determined treatment period, the installation comprising means for the addition of the treatment gas to the flow of liquids so as to form a homogeneous two-phase treatment medium, means for the forced dissolution of the treatment gas in the flow of liquids to be treated cooperating with means for the degassing of the two-phase treatment medium so as to produce a monophase treatment medium and contactor means providing for a plug flow of the degassed monophase treatment medium during the pre-determined treatment period. A
particular exemplary application of the installation is to the ozonation of liquids.
