Abstract
Official abstract text for this publication.
Disclosure relates to an electrochemical membrane degassing apparatus including a liquid channel in which raw water flows, a gaseous channel in which gas degassed from the raw water flows, a gas separation membrane allowing gas in the raw water to be moved to the gaseous channel, a surface modification layer formed at the gas separation membrane, and a power supply unit applying power to the surface modification layer, and selectively operated in either of a first process mode applying a low voltage power and a second process mode applying a high voltage power, wherein in the first process mode, an electrostatic repulsive force is generated between the surface modification layer and organic particles, and in the second process mode, a radical is generated, and the organic particles is oxidized by the radical. Accordingly, the efficiency of membrane degassing can be improved and membrane contamination can be prevented.
First claim
Opening claim text (preview).
The invention claimed is: 1 . An electrochemical membrane degassing apparatus comprising: a liquid channel in which raw water flows, a gaseous channel in which gas degassed from the raw water flows, a gas separation membrane disposed between the liquid channel and the gaseous channel, and allowing gas in the raw water flowing in the liquid channel to be moved to the gaseous channel, a surface modification layer formed on one side surface of the gas separation membrane and made of an electroconductive material, and a power supply unit applying power to the surface modification layer, and selectively operated in either of a first process mode in which a low voltage power is applied, and a second process mode in which a high voltage power is applied, wherein in the first process mode, as the low voltage power is applied, an electrostatic repulsive force is generated between the surface modification layer and organic particles in the raw water; and in the second process mode, as the high voltage power is applied, a radical is generated, and the organic particles in the raw water is oxidized by the radical. 2 . The electrochemical membrane degassing apparatus of claim 1 , wherein, in the second process mode, as the high voltage power is applied, microbubbles are generated in the surface modification layer and thus matter absorbed by at least one of the surface modification layer and the gas separation membrane is removed. 3 . The electrochemical membrane degassing apparatus of claim 2 , wherein the surface modification layer is made of one of or a combination of at least two or more of a conductive carbon-based material, metal-organic frameworks, and conductive polymers. 4 . The electrochemical membrane degassing apparatus of claim 3 , wherein the carbon-based material includes one of or a combination of at least two or more of activated carbon, carbon nanotubes, and graphene. 5 . The electrochemical membrane degassing apparatus of claim 2 , wherein, in the second process mode, the radical is generated by an ionic substance in the raw water. 6 . The electrochemical membrane degassing apparatus of claim 2 , wherein, in the second process mode, a gaseous by-product generated in a process of oxidation of the organic particles passes through the gas separation membrane to be moved to the gaseous channel.
