The present invention relates to a method of treating lime mud slurry being generated in a causticizing process in a pulp mill in a disc filter, in which method the lime mud is fed in the filter, thickened on the filter discs and removed from the filter discs. The lime mud is treated in at least two stages in one and the same disc filter in such a way that the lime mud slurry entering the filter is fed onto only a part of the filter discs, on which lime mud is thickened and removed from the discs, and the removed lime mud is re-slurried in liquid, and the lime mud slurry thus obtained is fed onto a second part of the filter discs, on which lime mud is thickened and removed from the filter and led into a subsequent process stage. The invention also relates to an apparatus. |
