This invention relates to a device for separation of oil from water containing impurities in industries waste plants, ships or the like. The device consists of an oil separation tank (I), which is tapering upwards and is provided with an inlet (1) and an outlet (2). In its lower part it is provided with airing means in the form of perforated pipes. In its upper part the tank is provided with steering plates (6). Raw water (3') containing oil (3') and light particles, is introduced in the inlet (1) of the tank (I), in which oil (3") and particles are lifted up to the surface by the addition of air bubbles from the airing means (4 and 5). The floating mass is flushed into an oil outlet pipe (7), while cleansed water (8) is led out through the outlet (2). The inlet (1) and the outlet (2) have a level regulator or level indicator.

Cette invention décrit un dispositif servant à la séparation de l'huile des impuretés contenant de l'eau dans les installations de traitement des déchets industriels, les bateaux, etc. Ce dispositif est constitué d'un réservoir de séparation d'huile (I) de forme conique vers le haut, pourvu d'une entrée (1) et d'une sortie (2). Sa partie inférieure est pourvue d'un dispositif d'aération constitué de tuyaux perforés, et sa partie supérieure est pourvue de plaques d'agitation (6). On introduit l'eau brute (3') contenant l'huile (3') et les particules légères par l'entrée (1) du réservoir (I), dans lequel l'huile (3") et les particules sont soulevées jusqu'à la surface par l'addition de bulles d'air provenant du dispositif d'aération (4 et 5). La masse flottante est ensuite chassée par le tuyau de sortie de l'huile (7), alors que l'eau purifiée (8) est acheminée par le tuyau de sortie (2). L'entrée (1) et la sortie (2) sont pourvues d'un dispositif de régulation du niveau ou d'un indicateur de niveau.
