Abstract

L'invention concerne un procédé d'épuration des eaux de lavage ou eaux usées provenant du retraitement de vieux papiers, par élimination des corps étrangers, en particulier des matières hydrophobe. Selon l'invention l'eau à épurer est mélangée à des savons de calcium agissant comme collecteur des matières hydrophobes ; ces savons sont séparés desdites matières hydrophobes par décantation, flottation, centrifugation ou filtration, et l'eau ainsi épurée est recyclée dans le circuit de retraitement. Le procédé de l'invention permet en particulier de séparer très rapidement les particules d'encre d'imprimerie contenues dans les eaux de lavage ou eaux usées.
