The invention relates to a method and an installation for treating liquids, especially for purifying contaminated water. Said method consists of the following steps: the raw water is pre-purified by adding a foam-forming reaction agent; the pre-purified water undergoes a main purification process by foaming the water with ionising radicals contained in the exhaust from the subsequent steps, in a known perforated cylinder washer (21); the foam formed is eliminated; the de-foamed water is ionised; and the impurities in the purified water are sedimented. The purified water is then additionally purified, the mud consisting of impurities from the pre-purification and the main purification process is physically separated, and the transformation of raw water into purified water is carried out continuously.
L'invention concerne un procédé et une installation pour traiter des liquides, notamment pour purifier de l'eau contaminée. Ce procédé consiste à effectuer tout d'abord une purification préalable de l'eau brute en ajoutant un agent de réaction moussant, puis à effectuer une purification principale de l'eau ayant subi la purification préalable, par moussage de l'eau, dans un laveur à cylindre perforé connu, avec des radicaux d'ionisation contenus dans les émissions gazeuses, provenant des étapes ultérieures. La purification principale comprend en outre les étapes suivantes : élimination de la mousse formée ; ionisation de l'eau dépourvue de mousse et sédimentation des impuretés dans l'eau purifiée. Ledit procédé consiste ensuite à effectuer une purification supplémentaire de l'eau purifiée puis à séparer physiquement les boues constituées d'impuretés, provenant de la purification préalable et la purification principale, la transformation de l'eau brute en eau pure s'effectuant en continu.
