Document Type and Number:
WIPO Patent Application WO/2024/053363
Kind Code:
A1
Abstract:
In order to decrease the total amount of dialysate used in dialysis methods, a liquid purification device and a liquid purification method that supply supplementary liquid at an appropriate position of a regeneration circuit are provided. An unpurified liquid passage (11) introduces unpurified liquid (F11) into a first part (110) of a separation device (100). A purified liquid passage (12) evacuates purified liquid (F12) from the first part (110) of the separation device (100). A diafiltrate passage (21) evacuates diafiltrate (F21) from a second part (120) of the separation device (100) and introduces a part thereof into a regeneration circuit (200). A regenerated liquid passage (22) introduces regenerated liquid (F22) from the regeneration circuit (200) into the second part (120) of the separation device (100). A first supplementary liquid passage (412) introduces first supplementary liquid (F41) directly into the purified liquid passage (12).
