Abstract
A tunable membrane configuration for a filtration or selective fluidic isolation and recovery device includes a housing having an inlet at one end and an outlet at an opposite end with an opening extending from the inlet to the outlet. An internal support structure is maintained in the opening, and layered filtration media is carried by the internal support structure, the media separating feed received at the inlet into at least three separate output flows.
Claims26
A filtration or selective fluidic isolation and recovery device, comprising:
- a housing having an inlet at one end and an outlet at an opposite end, said housing having an opening extending from said inlet to said outlet;
- an internal support structure maintained in said opening;
- a tunable membrane configuration, comprising:
- a layered filtration media carried by said internal support structure for separating feed received at said inlet into at least three separate output flow paths;
- wherein said layered filtration media comprises:
- at least three flow channels;
- at least two different planar membranes disposed adjacent two of said at least three flow channels, wherein at least one of said two different planar membranes comprises an electrically tunable graphene material;
- and
- a switchable voltage supply configured to supply a voltage along a length of the electrically tunable graphene material.
