Prediction method of fine particle breakage time of non-regenerative ion exchange resin device and management method of non-regenerative ion exchange resin device

摘要

PROBLEM TO BE SOLVED: To provide a method for predicting a fine particle breakage time of a non-renewable ion exchange resin apparatus. A part of water W1 to be treated of a non-renewable ion exchange resin device 25 includes a first path 31 provided with a first fine particle total 34 arranged in parallel with the non-renewable ion exchange resin device 25. A second path 32 including a first small resin column 35, a second fine particle meter 36, a flow rate control valve 37 and a first flow meter 38, a second small resin column 39, and a third fine particle meter 40. , Water is passed through a second path 33 provided with a flow rate adjusting valve 41 and a second flow meter 42, respectively.
