Abstract

La présente invention concerne un procédé de traitement de séparation par flottation d'une eau brute qui comprend les étapes suivantes: l'envoi de particules flottantes dans l'eau brute, la formation d'agrégats contenant des particules flottantes formées des particules flottantes et de matières en suspension et/ou d'agglomérats provenant de l'eau brute auxquels sont collées les particules flottantes, et un temps pendant lequel on laisse flotter les agrégats contenant les particules flottantes provenant de l'eau brute, afin que se séparent les agrégats contenant les particules flottantes provenant de l'eau brute. Cette invention concerne également un système de traitement de séparation par flottation d'une eau brute qui permet de mettre en oeuvre ledit procédé. Ce procédé constitue une technique de séparation rapide des solides-liquides qui permet de séparer, en un temps très court, des matières en suspension et/ou des agglomérats présents dans une eau brute.
