Abstract
Separation device comprising a feed channel including a shear region, permeate passage(s) extending perpendicular to the direction of the feed flow and a porous medium positioned between the shear region of the feed channel and the permeate passage(s). Separation process comprising generating a shear layer in a feed fluid and passing permeate into the permeate passage(s).
Claims25
A separation device comprising:
- a feed channel including a shear region;
- a plurality of permeate passages operatively associated with the shear region of the feed channel;
- at least first and second flow/pressure control devices, each control device being arranged to control permeate flow or pressure within at least one permeate passage independently of the flow or pressure within another permeate passage;
- and
- a porous medium positioned between the shear region of the feed chamber and the permeate passages, wherein the shear region is positioned along a first side of the porous medium and the plurality of permeate passages are positioned along a second, opposite side of the porous medium, each permeate passage fluidly communicating with the shear region through the porous medium.
