Document Type and Number:
WIPO Patent Application WO/2021/029094
Kind Code:
A1
Abstract:
Provided is a method for predicting particulate breakthrough time for a non-regenerative ion exchange resin device, wherein a portion of water W1 to be treated by a non-regenerative ion exchange resin device 25 passes through each of the following that are disposed in parallel with the non-regenerative ion exchange resin device 25: a first path 31 that comprises a first particle counter 34; a second path 32 that comprises a first compact resin column 35, a second particle counter 36, a flow rate regulating valve 37, and a first flow meter 38; and a second path 33 that comprises a second compact resin column 39, a third particle counter 40, a flow rate regulating valve 41, and a second flow meter 42.
