Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for managing a crystallization reaction tank the throughput of which can be maintained and the surrounding pipelines and/or a chemical pump of which can be prevented from being damaged and broken down owing to overload by preventing a flow passage of a crystallizing chemical from being clogged. SOLUTION: The managing method for the crystallization reaction tank provided with a crystallizing chemical for supplying the chemical liquid to the reaction tank liquid supplying line comprises a step to clean the crystallizing chemical liquid supplying line by making an acid solution pass through the crystallizing chemical liquid supplying line after raw water containing the component to be crystallized and the crystallizing chemical liquid are supplied to the crystallization reaction tank and the supplied raw water is crystallized.
