Zusammenfassung:	Provided is a method of dewatering aqueous sludge that is produced by waste water or sewage treatment facilities, such as from industrial and municipal processes. The method includes treating an aqueous sludge with an associative and branching or cross-linked inverse emulsion cationic polymer, wherein the associative properties of the cationic polymer are provided by an emulsification surfactant(s) chosen from diblock and triblock polymeric surfactants and/or cross-linking agents.
