Abstract

Procédé de traitement de fluides, notamment d'eaux usées associant des étapes de coagulation/ floculation, clarification par décantation ou flottation et une étape de filtration sur membranes de micro-, ultra-, nano ou hyper-filtration, caractérisé en ce qu'il comporte une double injection d'un ou de plusieurs réactifs de coagulation, respectivement 75,0 à 125 % de la dose optimale de coagulation ou dose annulant le potentiel Zêta (pZ), dans une zone (zone n°1) située en amont de l'étape de clarification (2) et 0,1 à 25,0 % de la dose optimale annulant le pZ, dans une seconde zone (zone n°2) située en amont de l'étape de filtration sur membranes (4) .
