(57) [Summary]nThis is a method of agglomerating particulate matter in papermaking or water clarification, in which a zeolite crystalloid aggregating agent is added to water containing a solid, a polyvalent cation, and a cationic acrylamide polymer. The zeolite crystalloid flocculant is preferably formed by mixing an aqueous sodium silicate and sodium aluminate solution to form a reaction mixture, which is then sufficiently formed to form a zeolite crystalloid flocculant having a particle size of at least about 4 nm. It is prepared by reacting for a long time. |
