Title:
DEVICE AND METHOD FOR REDUCING ION CONCENTRATION IN AQUEOUS LIQUID HELD IN SYSTEM, AND APPARATUS EQUIPPED WITH SAID DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/171383
Kind Code:
A1
Abstract:
Disclosed is a device for reducing the ion concentration in an aqueous liquid (201) held in a system (200). The device is equipped with at least one ion adsorption unit (100). The ion adsorption unit (100) is equipped with a liquid passage and multiple electrode pairs arranged in the liquid passage. The liquid passage is equipped with an inlet port (110a) and an outlet port (110b) both of which are connected to the system (200) so as to form a circulation path that includes the liquid passage and the system (200). Each of the electrode pairs comprises a first electrode and a second electrode. The first electrode contains a first electrically conductive substance containing activated carbon. The second electrode contains a second electrically conductive substance containing activated carbon. Each of the first electrode and the second electrode faces a void in which the aqueous liquid (201) flows.
