Abstract
The invention provides a cross-flow separation element comprising a single-piece rigid porous support (2) having within its volume at least one channel (41) for passing a flow of the fluid medium for treatment, which channel presents a flexuous flow volume (V1) defined by sweeping a generator section along a curvilinear path around a reference axis, and in that the reference axis does not intersect said generator section and is contained within the volume of the porous support.
Claims22
A cross-flow separation element for separating a fluid medium into a filtrate and a retentate, comprising:
- single-piece rigid porous support;
- at least one channel contained within the support, the channel being fully laterally enclosed by channel walls and having an inlet opening formed in a first end of the support, and an outlet opening formed in a second end of the support;
- wherein the channel extends in a flexuous path around a reference axis contained within the volume of the support, the channel walls having a shape defined by sweeping a generator plane section along a curvilinear path around said reference axis;
- and
- wherein the channel does not intersect the reference axis.
A method of forming a cross-flow separation element, comprising:
- forming superposed individual plies that are successively bonded to one another so as to grow progressively the three-dimensional shape of a support, in such a way that the formed cross-flow separation element comprises a single-piece rigid porous support, at least one channel contained within the support, the channel being fully laterally enclosed by channel walls and having an inlet opening formed in a first end of the support, and an outlet opening formed in a second end of the support;
- wherein the channel extends in a flexuous path around a reference axis contained within the volume of the support, the channel walls having a shape defined by sweeping a generator plane section along a curvilinear path around said reference axis;
- and wherein the channel does not intersect the reference axis of the support.
