DISPOSITIF ET PROCEDE DE TRAITEMENT D'EAU PAR ECUMAGE

摘要

The invention relates to apparatus for treating water by skimming, the apparatus comprising: a reaction chamber ( 8 ); injector means ( 4 ) for delivering the water for treatment via an injection orifice into the reaction chamber; means ( 20 ) for forming microbubbles of gas in the water to be treated; and condensation means ( 10 ) for collecting the resulting foam, the apparatus being characterized by the fact that the microbubbles are injected into the reaction chamber ( 8 ) together with the water for treatment. The invention also provides a method of treating water by skimming, in which: the water for treatment is injected into a reaction chamber ( 8 ); microbubbles of gas are formed in the water for treatment; and the foam that is produced is separated from the water for treatment, the method being characterized by the fact that the microbubbles are injected into the reaction chamber ( 8 ) together with the water for treatment.
