CA 2485227

Preferred aspects of the present invention relate to advances in rotating, vortex-enhanced reverse osmosis filtration. More particularly, the filtration device and methods incorporate a rotational drive mechanism adapted to use the flow of pressurized process fluid to cause rotation of a rotor within a housing, thereby creating shear and Taylor vortices in the gap between the rotor and housing. The improvements disclosed herein facilitate continuous use of vortex-enhanced filtration for prolonged periods of time.

Des aspects préférés de la présente invention concernent des progrès réalisés en matière de filtration par osmose inverse et rotation améliorée par vortex. En particulier, le dispositif et les procédés de filtration selon l'invention font intervenir un mécanisme d'entraînement rotatif conçu pour utiliser l'écoulement du fluide de procédé sous pression pour entraîner la rotation d'un rotor à l'intérieur d'un carter de façon à créer des vortex de cisaillement et de Taylor dans l'espace entre le rotor et le carter. Les améliorations apportées facilitent une utilisation continue de systèmes de filtration améliorée par vortex pendant une durée prolongée.
