The present invention relates to a process for the elimination of heavy metals from a closed white water system within the pulp and paper industry, wherein one adjusts the pH of the white water to between 5 and 11, and that one subsequently precipitates the resins present using a flocculation agent, whereby a simultaneous elimination of the heavy metals is obtained.
