Title:
HIGH-FLUX FORWARD OSMOSIS MEMBRANE ASSEMBLY, AND FORWARD OSMOSIS MODULE CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2015/030448
Kind Code:
A1
Abstract:
The present invention relates to a high-flux forward osmosis membrane assembly and a forward osmosis module using the same, and more specifically, to: a forward osmosis membrane assembly capable of improving the flux inside an osmosis membrane and simultaneously promoting uniform flux along a fluid flow route by forming more channels inside the osmosis membrane in order to allow an osmotic action to be smoothly carried out even if formed in a spiral shape, and minimizing the separation, which could occur, of a different adhered osmosis membrane by minimizing the concentration polarization on the surface of the forward osmosis membrane by increasing the flux on the surface of the osmosis membrane through the promotion of turbulence along the channels and simultaneously forming separate channels inside the osmosis membrane; and a forward osmosis module in which the active area of a separation membrane capable of carrying out a smooth osmotic action and forming an osmotic pressure gradient is maximized by using the same.
