The invention provides blends of high molecular weight, water-soluble cationic structure polymers with high molecular weight, water-soluble, cationic polymers which either are linear or which have a lower degree of structure. The blends are useful for dewatering dispersions of suspended solids, achieving good dewatering rates at relatively low dosage levels.
L'invention porte sur des mélanges à poids moléculaire élevé, sur des polymères structurés, cationiques, solubles dans l'eau à poids moléculaire élevé, sur des polymères cationiques solubles dans l'eau qui sont linéaires ou qui ont un degré inférieur de structure. Les mélanges sont utilisés pour déshydrater des dispersions de solides en suspension, et obtenir de bons taux de déshydratation à des niveaux de dosage relativement bas.
