Abstract
A device for separating a mixture comprised of at least a continuous phase I and at least a disperse phase II, one of the phases being a light phase and the other being a heavy phase, comprising canalization means for canalizing a current of the mixture and suited for communicating thereto a helical motion along a central shaft (A) and filtration means, the motion leading to a differentiated radial displacement of the light phase and of the heavy phase under the action of the centrifugal force, during which the continuous phase I flows at least partly through said filtration means. The canalization means and filtration means are arranged to define a helical passage which decreases according to a direction of flow of the mixture through the device.
