Abstract
The invention provides blends of high molecular weight, water-soluble cationic structured 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.
