Method and equipment for purification of a liquid, where the liquid is polluted by other liquids or solid material, e.g. removing oil from oil contamined water, comprising a flocculation device (2) and a flotation device (8). The method comprises adding one or more chemicals to the liquid in a flocculation device that comprises one or more pipe loops (2) with built-in agitators (3, 20, 21) providing turbulence and plug-type flow through the loop. Thereupon purified liquid and pollutants are separated in the flotation device or in a sedimentation device (8). The equipment according to the invention comprises a pipe loop (2), provided with built-in agitator(s) (3, 20, 21), connected to the flotation device (8).
Procédé et installation pour l'épuration d'un liquide contaminé par d'autres liquides ou par une matière solide, et par exemple pour extraire le pétrole des eaux contaminées par du pétrole, comportant un dispositif de floculation (2) et un dispositif de flottation (8). Le procédé consiste à ajouter un ou plusieurs produits chimiques au liquide dans un dispositif de floculation comportant un ou plusieurs tuyaux coudés (2) incorporant des agitateurs (3, 20, 21) qui créent des turbulences et un écoulement du type piston dans le tuyau, et à séparer le liquide purifié des polluants dans le dispositif de flottation ou dans un dispositif de décantation (8). Ladite installation comporte un tuyau coudé (2) incorporant un ou plusieurs agitateurs (3, 20, 21) et relié au dispositif de flottation (8).
