Abstract

L'INVENTION CONCERNE LA DETOXIFICATION DES FLOCULANTS CATIONIQUES. SELON L'INVENTION, ON AJOUTE AUX EAUX TRAITEES PAR UN FLOCULANT CATIONIQUE POLYMERE QUI LES REND TOXIQUES UN POLYMERE ANIONIQUE OU UN SEL D'UN ACIDE ORGANIQUE OU LEURS MELANGES.THE INVENTION RELATES TO DETOXIFICATION OF CATIONIC FLOCCULANTS. ACCORDING TO THE INVENTION, ANIONIC POLYMER OR A SALT OF AN ORGANIC ACID OR THEIR MIXTURES ARE ADDED TO WATERS TREATED WITH A POLYMER CATIONIC FLOCCULANT WHICH MAKES THEM TOXIC.
