Abstract

L'invention concerne un procédé servant à clarifier de l'eau chargée d'encre provenant du recyclage de charges de papier et consistant à traiter cette eau au moyen d'une dispersion hydrophile de polymère. Ce polymère est un copolymère d'un monomère cationique d'halogénure d'ammonium de diallyl N,N-disubstitué et de métacrylamide (AcAm). Suivant le dosage avec le polymère, on obtient un floculat. Ce floculat contient de l'encre et des impuretés qu'on supprime du flux de traitement d'eau au moyen d'un procédé de séparation entre solides et liquides qui consiste à faire flotter de l'air dissous. On obtient un copolymère préféré à partir de DADMAC et d'AcAm.
