Abstract
A device for separating solids from suspension comprises two filtering belts pervious to water travelling in the same direction and arranged to be supported and guided each by their respective liquid withdrawing surfaces provided with holes which form therebetween a prefiltering chamber converging in the direction of travel. The prefiltering chamber comprises in the beginning a supply inlet for supplying suspension to be treated into the chamber, as well as sealing elements defining the chamber at its sides in directions perpendicular to the direction of travel of the belts. The sealing elements are formed by rigid walls rigidly joined to the liquid withdrawing surfaces, such that the prefiltering chamber has a substantially closed housing-like construction.
