Title:
MACROMOLECULAR COAGULANT AND SLUDGE DEHYDRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/027312
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a high-performance macromolecular coagulant in powder form that shows outstanding dehydration performance on dehydration-resistant sludge, resolves transportation cost problems, and can be used in existing general-purpose equipment such as automatic powder melting devices and the like that have been in wide use. In particular, the present invention addresses the problem of providing an outstanding polymer coagulant that, in addition to exhibiting outstanding dehydration performance on dehydration-resistant sludge, can perform dehydration processing with only a small amount thereof. These problems can all be solved by a macromolecular coagulant in powder form that includes a water-soluble polymer (A) that shows specific solution properties and a water-soluble polymer (B) that shows solution properties different from those of the water-soluble polymer (A). That is, this macromolecular coagulant in powder form exhibits outstanding dehydration performance, resolves transportation cost problems, and can be used in existing general-purpose equipment such as automatic powder melting devices and the like that have been in wide use.
