Abstract
La présente invention concerne un système de récupération des eaux usées à des fins de réutilisation, les eaux usées traitées une seconde fois pouvant être récupérées en eau domestique par amélioration de l'efficacité de coagulation et de filtration même de substances flottantes fines. La présente invention peut être mise en œuvre grâce aux éléments suivants : une pompe de transfert d'eau brute qui permet un pompage et un transfert des eaux usées traitées une seconde fois ; une partie de pulvérisation de coagulant qui permet la pulvérisation d'un coagulant et la pulvérisation du coagulant sur les eaux usées traitées, transférées par la pompe de transfert d'eau brute ; une partie de traitement de boue qui permet l'élimination d'une boue coagulée par le coagulant ; une partie de filtration/traitement de boue fine qui permet un second filtrage/traitement des fines substances étrangères dans l'eau traitée de laquelle la boue a été éliminée. Ledit système présente l'avantage selon lequel un processus de prétraitement est simplifié, ce qui permet de réduire la taille de l'installation, et l'efficacité d'élimination de fines substances flottantes est excellente, ce qui permet d'augmenter le taux de réutilisation des eaux usées.
