Abstract
A process for fractionating a suspension of solid particles in a liquid, of he type wherein said suspension is made to pass through a filtering screen, characterized in that said suspension is directed in a direction parallel to the longitudinal axis of an elastically deforming, flexible, perforated sleeve forming a filtering screen, and in that a sequence of high and low pressures is continuously created within this sleeve and travels at least predominantly opposite the direction of the suspension flow. The invention also applies to equipment.
