Title:
DEVICE FOR PURIFYING FLUID USING ION CONCENTRATION POLARIZATION PHENOMENON AND PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/186679
Kind Code:
A2
Abstract:
The present invention relates to a device for purifying a large amount of fluid using an ion concentration polarization phenomenon and a purification system. A purification device (100) according to an embodiment of the present embodiment is a purification device for purifying a large amount of fluid using an ion concentration polarization phenomenon, comprising: an injection channel (120) having an entrance provided on one end thereof such that a substance to be purified is injected; a purification channel (140) and a discharge channel (160) branching off from the other end of the injection channel (120) via a mesh portion (150) such that the purified substance (F) is discharged through the purification channel (140), and the remaining substance (B') to be purified is discharged through the discharge channel (160); an ion-selective membrane (180) contacting at least one side of the mesh portion (150); and a buffer portion (200) arranged on the other side of the ion-selective membrane (180) contacting the mesh portion (150), wherein the mesh portion (150) has an ion-selective coating layer (155) formed on the surface thereof, and when an electric field is applied, an ion concentration polarization phenomenon (ICP) phenomenon occurs to the other end of the injection channel (120) and to the adjacent part of the mesh portion (150), thereby forming an ion depletion zone.
