Polymeric flocculant and method of sludge dehydration |
| abstract |
The invention provides a flocculant which in sludge dewatering gives flocs having an excellent balance among flocculating strength, filtration rate and moisture content, and a method of sludge dewatering with the flocculant. n Namely, the flocculant is a polymeric flocculent which contains a copolymer having alkoxyalkyl units or a poly(alkylene oxide) unit and further having water-soluble monomer units; and the method of sludge dewatering includes adding the polymeric flocculant to a sludge after or without adding an inorganic flocculent or an organic cationic compound thereto and then dewatering the sludge. |
