Abstract

Ce procédé de traitement d'un milieu aqueux consiste à appliquer un courant électrique direct possédant une certaine amplitude, à ce milieu aqueux placé dans une cellule électrolytique (I), et à faire s'écouler à une vitesse telle le liquide dans la cellule électrolytique, que l'on obtient un effet combiné d'enlèvement de tartre et de désinfection.
