Abstract:
(EN) Disclosed are a desalination apparatus and a desalination method using a multi-stage forward osmosis process. A desalination apparatus according to an embodiment of the present invention comprises a first forward osmosis unit and a second forward osmosis unit. The first forward osmosis unit comprises: a first forward osmosis membrane; a first feed channel which is in contact with one side of the first forward osmosis membrane and through which wastewater is introduced; and a first draw channel which is in contact with the opposite side of the first forward osmosis membrane and into which a first draw solution flows. The second forward osmosis unit comprises: a second forward osmosis membrane; a second feed channel which is in contact with one side of the second forward osmosis membrane and into which the diluted first draw solution discharged from the first draw channel flows; and a second draw channel which is in contact with the opposite side of the second forward osmosis membrane and into which the second draw solution flows.
(FR) L'invention concerne un appareil de dessalement et un procédé de dessalement utilisant un processus d'osmose directe à étages multiples. Un appareil de dessalement selon un mode de réalisation de la présente invention comprend une première unité d'osmose directe et une seconde unité d'osmose directe. La première unité d'osmose directe comprend : une première membrane à osmose directe ; un premier canal d'acheminement qui est en contact avec un côté de la première membrane à osmose directe, et à travers lequel les eaux usées sont introduites ; et un premier canal d'aspiration qui est en contact avec le côté opposé de la première membrane à osmose directe, et dans lequel circule une première solution d'aspiration. La seconde unité d'osmose directe comprend : une seconde membrane à osmose directe ; un second canal d'acheminement qui est en contact avec un côté de la seconde membrane à osmose directe, et dans lequel circule la première solution d'aspiration diluée évacuée du premier canal d'aspiration ; et un second canal d'aspiration qui est en contact avec le côté opposé de la seconde membrane à osmose directe, et dans lequel circule la seconde solution d'aspiration.
(KO) 다단 정삼투 공정을 이용한 담수화 장치 및 담수화 방법이 개시된다. 본 발명의 일 실시예에 따른 담수화 장치는 제1 정삼투 유닛과 제2 정삼투 유닛을 포함한다. 제1 정삼투 유닛은 제1 정삼투막과, 제1 정삼투막의 일면과 접하며 폐수가 유입되는 제1 피드 채널과, 제1 정삼투막의 반대면과 접하며 제1 유도 용액이 유입되는 제1 드로우 채널을 포함한다. 제2 정삼투 유닛은 제2 정삼투막과, 제2 정삼투막의 일면과 접하며 제1 드로우 채널에서 배출된 희석된 제1 유도 용액이 유입되는 제2 피드 채널과, 제2 정삼투막의 반대면과 접하며 제2 유도 용액이 유입되는 제2 드로우 채널을 포함한다.
