Abstract
A device for extracting a liquid phase from a suspension, the device being characterized in that it comprises: a main duct for conveying a flow of said suspension, the duct being of a length that is sufficient to enable a layer of said suspension to develop that is depleted in solid phase; flow disturbance means for disturbing the flow of said suspension, said means being provided in the main duct and being adapted to cause at least one recirculation vortex to form so as to increase locally the thickness of said depleted layer; and liquid extraction means disposed in a region of the device where said suspension is enriched in liquid phase as a result of said recirculation vortex. A method of extracting a liquid phase from a suspension, the method comprising injecting said suspension into such a device at a flow rate suitable for causing at least one recirculation vortex to be formed, and extracting a fraction of said suspension that is enriched in liquid as a result of said vortex.
