<p>PROBLEM TO BE SOLVED: To provide an organic coagulant excellent in coagulation and decoloring effects and a coagulation and flocculation treatment agent excellent in coagulation and flocculation performances such as the coarsening of floc, the increase of floc strength, the reduction of water content in dewatered cake, filtrate decoloring, COD reduction and the like.SOLUTION: A powdery organic coagulant (P) includes a water-soluble (co)polymer (A)having an intrinsic viscosity [η] of 0.10-3.0 produced by the reversed phase suspension polymerization of an unsaturated monomer containing a water-soluble cationic monomer denoted as general formula (1): CH=C(R)-CO-Q-X-NRRRZ(1).</p> |
