Electrochemical membrane degassing apparatus

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.
