Title:
TARGET LIQUID TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/043193
Kind Code:
A1
Abstract:
Provided is an apparatus capable of efficiently removing a to-be-removed material such as unnecessary ions from a target liquid such as a dialysis waste liquid while ensuring the fluidity of the dialysis waste liquid or the like. The concentration of the to-be-removed material in the target liquid in a first flow passage (11) on the upstream side from a site thereof merging with a second flow passage (12) is measured as a first concentration C1 on the basis of the output signal of a first concentration sensor (S1). The concentration of the to-be-removed material in the target liquid in the first flow passage (11) on the downstream side from the site merging with the second flow passage (12) is measured as a second concentration C2 on the basis of the output signal of a second concentration sensor (S2). When the difference ΔC between the first concentration C1 and the second concentration C2 is less than a concentration difference threshold, an opening degree decrease of a first flow-rate adjustment valve (110) and/or an opening degree increase of a second flow-rate adjustment valve (120) is executed.
