The present invention concerns a method for the purification of water, for example, excess water from a wood room in a forestry plant for the production of paper pulp, whereby the base raw material, wood, is chopped into small pieces, for example, chips, and whereby the forestry plant comprises a purification function that exists in the plant. According to the invention, the method is characterised by the following steps: the dirty wood room effluent is led from the washer and is returned to the plant in such a manner that a collaboration occurs with the wood that has been chopped into chips, such that the pieces of chips absorb and carry the wood room water; the wood room effluent, carried by the chips, is carried onwards into the process and reaches the purification function of the plant, which makes purification of the wood room effluent possible. |
