Patent ID: 8632681

Claim:
A forward osmosis (FO) device, the device comprising: a semi-permeable membrane capable of performing forward osmosis between a first (F 1 ) and a second fluid (F 2 ), a first fluid confinement positioned on a first side of the membrane, the first fluid confinement comprising a first swirl generator through which the first liquid (F 1 ) is conveyable to the first fluid confinement, and a second fluid confinement positioned on a second side of the membrane, the second side being opposite to the membrane relative to the said first side, the second fluid confinement comprising a second swirl generator through which the second liquid (F 2 ) is conveyable to the second fluid confinement, wherein the first and second swirl generator, upon engagement, are arranged to create a circular flow pattern (S 2 , S 3 ) for the first and the second fluid, respectively by rotating motion (RA 1 , RA 2 ).
