ABSTRACT A method is disclosed for the separation of dissolved wood substances in process water resulting from the production of wet process wood fiber board. The system includes, in turn, a preheater, a defibrator, a cyclone, a leaching device and a dewatering device for the ground fiber pulp. In the applicant's method the process water from the dewatering device is led back partly to the defibrator, and partly to an evaporation plant, from which generated water vapor is led to the preheater, thus creating a closed circulation water system including two paths. Surplus steam from the cyclone is led to the evaporation plant for energy generation in the evaporation plant, thus giving the closed water system one more path.
