A disc filter includes several triangular sectors that are connected from their neck section to the body of the disc filter. The sectors form a relatively thin disc that is rotated during filtration in a basin that contains a suspension to be filtered. The side surfaces of the sector have openings through which liquid in the suspension passes into several essentially radial flow channels inside the sector to flow on to the neck section and away from the sector. A separating wall is formed between two adjacent radial flow channels. Furthermore, the sector is made of two side elements, which are of plastic material and the mating surfaces of which are placed against each other.

A filter bag (1) for a disc-like filter, comprising filter surfaces (2) to be positioned on both sides of a filter element. The filter element is inserted into the filter bag, and the filter bag is heated so that the heated portion shrinks, thus tightening the filter bag around the filter element. The filter bag (1) is so shaped that the filter parts (2) to be positioned on both sides of the filter element are substantially of the same shape and size as the required filter surfaces. An edge part (3) of a material substantially impermeable to liquid and shrinkable at elevated temperature is attached to the edges of the filter parts.
