US Patent:

47909420, Dec 13, 1988

Filed:

Jun 10, 1987

Appl. No.:

7/061007

Inventors:

Iosif Shmidt - Brookyn NY
Mario Badiali - Bronx NY

Assignee:

Membrex Incorporated - Garfield NJ

International Classification:

B01D 1300
B01D 3306

US Classification:

210650

Abstract:

An improved method and apparatus for filtration includes an outer stationary body, an inner rotating body defining a gap with the outer body for receiving a fluid sample, the surface of one of the bodies defining the gap being a filter. The rotation of the inner body creates Taylor vortices which continuously displace occluded solute on the filter surface. The filter can be a membrane.

Abstract:

An improved method and apparatus for filtration includes an outer stationary body, an inner rotating body defining a gap with the outer body for receiving a fluid sample, the surface of one of the bodies defining the gap being a filter. The rotation of the inner body creates Taylor vortices which continuously displace occluded solute on the filter surface. The filter can be a membrane. The rotational speed and/or a driving force across the membrane may be varied to control the composition of the permeate.

International Classification:

B01D 1300

US Classification:

210650

Abstract:

An improved method and apparatus for filtration includes an outer stationary body, an inner rotating body defining a gap with the outer body for receiving a fluid sample, the surface of one of the bodies defining the gap being a filter. The rotation of the inner body creates Taylor vortices which continuously displace occluded solute on the filter surface. The filter can be a membrane. In one embodiment the device may be used to filter very small volumes of fluid such as are handled in clinical and other laboratories.
