상기 정삼투 방식은 반투막을 사이에 두고 두 용액의 삼투막 차를 이용하여 담수를 추출하도록 하는 방식이고, 역삼투 방식은 반투막을 사이에 두고 삼투압보다 높은 역삼투압을 해수에 가함으로써 담수를 추출하도록 하는 방식이며, 증류 방식은 해수를 가열하여 증발시킨 후 그 증기를 응축시켜서 담수를 얻는 방식이다.The forward osmosis method is to extract fresh water using the osmotic membrane difference between the two solutions with a semi-permeable membrane between, and the reverse osmosis method to extract the fresh water by applying a reverse osmosis pressure higher than the osmotic pressure to the sea water with the semi-permeable membrane between them. Distillation is a method of heating and evaporating seawater to condense the steam to obtain fresh water.
