Extraction module and methods for extraction of a target species

An extraction module comprising:

• an axial chamber having one or more openings, the axial chamber positioned about a central axis;
• and
• an extraction leaf, the extraction leaf comprising
• a first porous active layer comprising a fibrous mat;
• a first nonporous backing layer;
• a first porous spacer layer disposed between the first porous active layer and the first nonporous backing layer;
• a second porous spacer layer disposed on the first porous active layer on a side opposite the first porous spacer layer;
• optionally, a second porous active layer comprising a fibrous mat disposed on the second porous spacer layer on a side opposite the first porous active layer;
• optionally, a third porous spacer layer disposed on the second porous active layer on a side opposite the second porous spacer layer;
• and
• optionally, a second nonporous backing layer disposed on the second porous spacer layer on a side opposite the first porous active layer or, when present, on the third porous spacer layer on a side opposite the second porous active layer;
• wherein the extraction leaf extends outward from the central axis along a radially curved trajectory.
