A nonionic temperature-sensitive water-absorbing hydrogel PVMEG (polyvinyl-methylether gel), which swells and shrinks reversibly in response to a small temperature change, was applied to sludge dewatering as a water-absorbing medium. The water-absorbing rate of the gel varied with the properties and solid concentration of the sludge. All the sludges tested were dewatered quite well by repeated use of the gel.
