Low acrylamide flocculant composition, method of using low acrylamide flocculant composition

摘要

PROBLEM TO BE SOLVED: To provide a low acrylamide flocculant composition usable for various applications.SOLUTION: A low acrylamide flocculant composition includes an acrylamide-containing polymer flocculant and, in addition, at least one kind of auxiliary polymer flocculant selected from the group consisting of a poly(meth)acrylate, a salt of carboxymethylcellulose, an alginate, starch, guar gum and chitosan and the combination exhibits high flocculation ability. The low acrylamide flocculant composition can be widely used from water purification to sludge thickening without especially limiting applications since the acrylamide content of the whole flocculant composition is 0.05 mass% or less and it is low.SELECTED DRAWING: Figure 3
