Abstract

The invention relates to a method for treating liquid flows at a chemical pulp mill. The system comprises a cooking process for producing pulp, at least one washing stage for washing said pulp, at least one bleaching stage for bleaching the washed pulp, a waste water treatment plant comprising at least one purifying stage to purify effluents, and a raw water treatment plant comprising at least one purifying stage, and the method comprises conveying a liquid flow comprising a portion of purified effluents (45) coming from the waste water treatment plant (40) and/or a portion of process waters (35) to said at least one purifying stage of the raw water treatment plant (20) for purifying the liquid flow in said at least one purifying unit of the raw water treatment plant (20) to obtain recyclable water (29), and using said recyclable water as process water in at least one process and/or process stage at the pulp mill. In addition, the invention relates a system for treating liquid flows at a chemical pulp mill and a use of a raw water treatment plant of a chemical pulp mill for purifying process waters and/or effluents coming from the waste water treatment plant.
