It is essentially constituted by a roller covered with a hydrophobic and oleophilic material 5 partially surrounded by a mobile recipient 6 provided with evacuation means of the aqueous medium 52. This device is particularly well adapted to the deoiling of a decanting basin.Field of SearchResponsive to material levelWith separator inlet control Responsive to rotation Controlled discharge means Container movement operated With oil water skimmer With oil water sorption means Including temperature change Rotating drum Filtering immiscible liquids Using mechanical means (e.g., skimmers, pump, etc.) Using physical agent (e.g., sponge, mop, etc.) Movable medium Solid cleaner, e.g., scraper Drum type | |
