ABSTRACT:
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.
