Title:
FORWARD-OSMOSIS, CONTINUOUS-PROCESS, WATER-TREATMENT SYSTEM AND METHOD USING PHASE CHANGES IN AN OSMOTICALLY ACTIVE SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2012/081747
Kind Code:
A1
Abstract:
Disclosed are a forward-osmosis, continuous-process, water-treatment system and method using phase changes in an osmotically active substance (osmotically active compound, OAC), that can easily change phase, whereby it is possible to effect isolation and recovery processing of a draw solution through a concept involving continuous processing via forward osmosis by making use of the osmotically active substance (OAC). According to a preferred embodiment of the present invention, the forward-osmosis, continuous-process, water-treatment system using phase changes in an osmotically active substance is capable of providing drinking water production technology as it makes it possible to effect isolation and recovery processing of a draw solution through a concept involving continuous processing via forward osmosis by making use of the OAC that can easily change phase. The water-treatment process making use of an OAC that can easily change phase of this kind can be used in fields of industry involving water-treatment processing of all types including sewage and waste water, groundwater and the like, not to mention seawater desalination.
