ABSTRACT:
The invention relates to a method for extracting solids (23; 123) from a suspension (22; 122) containing the solids (23; 123) and suspension liquid (32; 132) in a continuously or virtually continuously operating filter device (10; 110) using a filtering material (26; 126), on the one side of which, the high-pressure side (30; 130), a higher pressure prevails than on its other side, the low-pressure side (42; 142), and which passes successively through a plurality of working zones (I-V; I-IV) of the filter device (10; 110) in a working direction (U), the suspension (22; 122) being supplied to the filtering material (26; 126) on its high-pressure side (30; 130) in a first working zone (I) and being filtered, the suspension liquid (22; 122) flowing through the filtering material (26; 126) on account of the difference in pressure between the high-pressure side (30; 130) and the low-pressure side (42; 142) while at least some of the solids (23; 123) are deposited on the filtering material (26; 126). As claimed in the invention, the solids (23; 123) which are deposited on the filtering material (26; 126) are resuspended in a washing liquid (50; 150), and the new suspension (resuspension) (53; 153) thus formed is filtered again in a second working zone (II) of the filter device (10; 110), which zone is arranged downstream of the first working zone (I) in the working direction (U).
