ABSTRACT:
In process for the separation of liquids from suspensions by means of at least one filter layer, on one side of which a suspension is fed and solids accumulate, and on the other side of which separated liquid is carried away, there is given an improved clearing of the feed side filter surface (ZFF) and thus a lengthened operation time until maintenance of the filter layer, through a flow movement (P.sub.1, P.sub.2) in the suspension chamber (SPR) with movement components oscillating in the normal direction in relation to the filter surface (ZFF), preferably through a suspension flow oscillating between filter surfaces (ZFF) lying opposite each other. An apparatus for the separation of liquids from suspensions makes possible such an improved operation through the suspension-drive device (AV.sub.1) with a plurality of surface elements (FE.sub.1, FE.sub.2) in the direction of movement and which can be flowed around transversely thereto (FIG. 5).
