  • Publication number: 20090137720
    Abstract: A flocculent composition and a method for manufacturing the same are provided. The flocculent composition has an excellent ability to adhere to suspended particles, does not cause an increase in the viscosity of sludge, provides good drainage during mechanical dewatering to allow a reduction in the water content of a cake, and is applicable to various types of sludge. These characteristics are obtained by utilizing advantages of a crosslinking water-soluble polymer and a linear water-soluble polymer and changing the compounding ratio of the crosslinking water-soluble polymer to the linear water-soluble polymer according to the form of the size distribution of sludge particles. The flocculent composition includes a vinyl polymer-type crosslinking water-soluble polymer (A) having a charge inclusion ratio of 20% or more and a vinyl polymer-type linear water-soluble polymer (B) having a charge inclusion ratio of 5% or more and less than 20%.
