ABSTRACT:
The invention concerns a filtering procedure by which the solid matter and the fluid contained in a sludge are separated in a box filter. The sludge is passed in the filter into a filtering space (2) between two opposite filter cloths (3), where the fluid is separated, whereupon the cake (13) of solid matter produced is dried by passing a stream of air through it. The essential feature of the invention is that the drying is performed by passing a stream of air into the cake (13) first from one side and then from the opposite side of the filtering space (2) in such manner that the air flows in opposite directions through the cake during these drying phases. Penetrating through the filter cloth (3) into the cake, the air causes the cake to be detached from the cloth. When the filtering space is opened, the cake thus detached and dried can be removed directly without specific detaching efforts.
