FORWARD OSMOTIC DESALINATION DEVICE USING MEMBRANE DISTILLATION METHOD IN WHICH PART OF DRAW SOLUTION IS FED DIRECTLY INTO FORWARD OSMOSTIC TYPE SEPARATOR

摘要

The present invention relates to a freshwater separator employing a membrane distillation method, and a forward osmosis desalination system comprising the freshwater separator. More particularly, the present invention relates to a desalination system in which only a portion of a diluted draw solution is separated into gas and freshwater in a freshwater separator and the other portion of the diluted draw solution is fed directly into a forward osmosis separator, so that the efficiencies of the seawater separator and the desalination system comprising same are increased and the energy consumption is reduced.
