摘要 |
A process for fractionating a suspension of solid particles in a liquid, of the 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 pressure is continuously created within this sleeve and travels at least predominantly opposite the direction of the suspension flow.
