Zusammenfassung:	For sieving biocompatible adsorbent beaded polymeric materials a column is filled with beads, a fluid is supplied into the column upwardly, a screening element located in the column between a bottom of the column and a top of the column so that beads below a predetermined threshold are displaced by the fluid flowing upwardly and through the screening element, while beads above the predetermined threshold are retained under the screening element, and another fluid is supplied downwardly so as to prevent clogging of said screening element and to agitate the polymeric beads in the column under the screening element.
