CONTROL METHOD FOR CRYSTALLIZATION REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a control method for a crystallization reactor not interlocking pellets in a crystallization reaction tank after the supply of raw water is stopped. SOLUTION: In the control method for the crystallization reactor, raw water containing a component to be crystallized is supplied to the crystallization reaction tank along with a crystallizing chemical liquid and subjected to crystallization treatment to form pellets. After the supply of raw water to the crystallization reaction tank is stopped but before the pellets are interlocked mutually, the treated water is circulated to the crystallization reaction tank at a flow velocity fluidizing the pellets in a crystallization part using a treated water circulating means without abrading the pellets.
