Document Type and Number:
Japanese Patent JP2000516536
Kind Code:
A
Abstract:
A method of coagulating particulates, as in papermaking or water clarification applications, for example, is provided wherein a zeolite crystalloid coagulant is added to water containing the solid matter, a source of multivalent cations, and a cationic acrylamide polymer. The zeolite crystalloid coagulant is preferably prepared by admixing aqueous sodium silicate and sodium aluminate solutions to form a reaction mixture and allowing a reaction to proceed for a sufficient time to form a zeolite crystalloid coagulant particles having particle sizes of at least about 4 nm before terminating the reaction.
