Abstract

PURPOSE: To dehydrate efficiently and continuously less filterable sludge, by vacuum-dehydrating the sludge while transferring by negative press. applied to the inner side of the filter surface to form cracks in the cake, then by pressurizing and pressing immediately the cake by the rotation of grooved rolls.
CONSTITUTION: Sludge 15 subjected to pretreatment, e.g., concentration, digestion, and flocculation, is fed from a charging box 8 onto the filter cloth 6. While being transferred in the direction of an arrow in a layer on the filter cloth, the sludge 15 is freed from the liq. contained in thd sludge by the suction force due to the negative press. of a suction box 1. The water content of the cake 16 is decreased to form cracks. Just after the crack formation, the cake is pressed successively by grooved rolls A, B, C to crush the crack and increase the dehydration ratio. Thereafter, the cake is strongly pressed by two flat rolls, then by grooved rolls once again so as to loosen the cake, and by a flat roll F to produce finally sheet-like cake 16 of very low water content.
