Abstract
(EN)
The present invention relates to a draw solute to be applied to a method for desalination and water purification using forward osmosis, and to a method for desalination and water purification using the draw solute. More particularly, the present invention relates to a thermo-responsive forward osmosis draw solute which has a molar mass of 50 to 3000 g/mol and a phase separation phenomenon occurring at temperatures from 0°C to 70°C, and to a method for desalination and water purification using the draw solute. According to the present invention, a thermo-responsive forward osmosis draw solute having optimum conditions for sea water desalination and purification of contaminated water using a forward osmosis can be provided. The method for desalination and water purification using the thermo-responsive forward osmosis draw solute consumes an extremely small amount of energy, is easy to apply, and enables very easy separation of the draw solute.

Cette invention concerne un soluté d'extraction destiné à être appliqué à un procédé de désalinisation et de purification d'eau par osmose directe, et un procédé de désalinisation et de purification d'eau l'utilisant. Plus particulièrement, cette invention concerne un soluté d'extraction thermoréactif pour osmose directe ayant un poids molaire de 50 à 3000 g/mol et subissant un phénomène de séparation de phase qui apparait à des températures de 0 à 70°C, et un procédé de désalinisation et de purification d'eau l'utilisant. Selon la présente invention, un soluté d'extraction thermoréactif pour osmose directe ayant des conditions optimales pour la désalinisation d'eau de mer et la purification d'une eau contaminée par osmose directe peut être obtenu. Le procédé de désalinisation et de purification d'eau faisant appel au soluté d'extraction thermoréactif pour osmose directe selon l'invention consomme une quantité d'énergie extrêmement faible, est facile à appliquer, et permet la séparation très facile du soluté d'extraction.

본 발명은 정삼투법을 이용한 담수화 및 정수방법에 적용시키기 위한 유도용질 및 이를 이용한 담수화 및 정수방법에 관한 것으로서, 더욱 구체적으로는, 50 내지 3000 g/mol의 몰질량을 가지며, 0℃ 내지 70℃에서 상분리 현상이 발생되는 온도응답성 정삼투 유도용질 및 이를 이용한 담수화 및 정수방법에 관한 것이다. 본 발명에 따르면, 정삼투법을 이용한 해수 담수화 및 오염수 정화에 사용되기에 최적의 조건을 갖는 온도응답성 정삼투 유도용질을 제공할 수 있으며, 이러한 온도응답성 정삼투 유도용질을 사용한 담수화 및 정수방법은 에너지 소모량이 거의 없으면서도, 적용이 간편하고, 유도용질의 분리가 매우 용이하다.
