Abstract:
A process of dewatering an aqueous suspension comprising treating the suspension with a dewatering amount of a reverse phase polymer, and subjecting the suspension to a mechanical dewatering to form a cake,characterized in that the reverse phase polymer only partially inverts to bring about flocculation and thickening of the suspension, and then fully inverts during the further dewatering to form a cake.
