Highly efficient desalination system and method using multi-stage ionic field-effect transistor

摘要

The present invention relates to a desalination system capable of obtaining high-purity drinking water, domestic water, industrial water, etc. by passing a fluid such as seawater or wastewater through a nano channel to remove ionic impurities contained in the fluid, The present invention relates to a high-efficiency desalination system and method capable of rapidly desalinating under low pressure conditions while applying a relatively small amount of energy to a desalination system using a desalination system. The present invention provides a desalination system for removing ionic impurities contained in a fluid by passing a fluid such as seawater or wastewater through a nano channel, wherein a plurality of the nano channels are arrayed Gate electrodes are sequentially arranged around the respective nanochannels so that voltages of different polarities are applied to the gate electrodes adjacent to each other to sequentially control the surface potential of the nanochannels to pass through the nanochannels The ionic impurities contained in the fluid are sequentially filtered out to desalinate.
