Abstract
Procédé et dispositif pour floculer et précipiter de manière contrôlée les substances etrangères à partir d'un liquide. Il consiste à ajouter à au moins une quantite partielle de liquide une dose d'agent de floculation, à mesurer par opacimétrie la floculation et la précipitation ainsi provoquées dans la quantité partielle, et à déterminer en fonction des résultats de l'opacimétrie la quantité d'agent de floculation à ajouter au liquide à traiter. Il peut être utilisé notamment pour l'épuration des eaux usées, industrielles ou communales, la préparation d'eau potable.
