Abstract

L'invention concerne des unités destinées à la séparation de matières mélangées dans un milieu filtré en écoulement et peut s'utiliser dans des stations d'épuration. Le procédé d'utilisation de l'unité filtrante consiste à faire passer le milieu filtré par un sorbant homogène placé dans des cassettes amovibles identiques, disposées dans un boîtier commun le long de l'écoulement du milieu. On interrompt le filtrage de façon périodique et l'on régénère le sorbant jusqu'à ce que la pureté initiale minimale admissible soit rétablie; on recommence ensuite le filtrage. Une fois que le sorbant de la première cassette dans le sens de l'écoulement est saturé jusqu'à un état dans lequel elle perd sa capacité de rétablir la pureté initiale minimale admissible, on remplace ladite cassette par la cassette suivante dans le sens de l'écoulement, et ainsi de suite. On installe à l'emplacement de la dernière cassette dans le sens de l'écoulement une cassette neuve contenant du sorbant frais. La cassette destinée au remplacement du sorbant peut être retirée via une trappe commune à toutes ou certaines cassettes du boîtier. L'unité peut contenir au moins deux boîtiers reliés parallèles dans le sens de l'écoulement. L'invention permet d'augmenter l'efficacité d'utilisation du sorbant.
