Title:
STOCK SOLUTION TREATMENT APPARATUS, STOCK SOLUTION TREATMENT APPARATUS OPERATING METHOD, AND ADJUSTER
Document Type and Number:
WIPO Patent Application WO/2023/021967
Kind Code:
A1
Abstract:
The stock solution treatment apparatus and stock solution treatment apparatus operating method according to the present invention can enhance stock solution treatment efficiency, the apparatus being easily controllable. The apparatus comprises a filtration device (10), a concentration device (20), a stock solution supplying unit (UB), a liquid supply flow path (2), a filtered liquid supply flow path (3), a concentrated liquid flow path (4), a waste liquid flow path (5), a collection unit (CB) that is connected to the concentrated liquid flow path (4) and collects concentrated liquid, a branch flow path (6) that communicates between the collection unit (CB) and the filtered liquid supply flow path (3), a liquid sending unit (3p) that is provided between the concentration device (20) and the connection of the branch flow path (6) in the filtered liquid supply flow path (3), and a control unit (30) that controls operation of the liquid sending unit (3p), wherein the liquid sending unit (3p) is operated such that after gravity filtration for supplying, by means of gravity force, a stock solution to the filtration device (10) from the stock solution supplying unit (UB) that is placed above a stock solution supply port (11a) of the filtration device (10) is started, and when a predetermined state is achieved, liquid is sent from the filtration device (10) to the concentration device (20); or the liquid sending unit (3p) is operated such that liquid is sent from the filtration device (10) to the concentration device (20) simultaneously with the start of gravity filtration for supplying, by means of gravity force, a stock solution to the filtration device (10) from the stock solution supplying unit (UB) that is placed above a stock solution supply port (11a) of the filtration device (10).
