Abstract
The invention relates to a method for extracting solids () from a suspension () containing the solids () and suspension liquid () in a continuously or virtually continuously operating filter device () using a filtering material (), on the one side of which, the high-pressure side (), a higher pressure prevails than on its other side, the low-pressure side (), and which passes successively through a plurality of working zones (I-V; I-IV) of the filter device () in a working direction (U), the suspension () being supplied to the filtering material () on its high-pressure side () in a first working zone (I) and being filtered, the suspension liquid () flowing through the filtering material () on account of the difference in pressure between the high-pressure side () and the low-pressure side () while at least some of the solids () are deposited on the filtering material (). As claimed in the invention, the solids () which are deposited on the filtering material () are resuspended in a washing liquid (), and the new suspension (resuspension) () thus formed is filtered again in a second working zone (II) of the filter device (), which zone is arranged downstream of the first working zone (I) in the working direction (U).
