A permeable membrane system (
) for the separation of fluid components includes a laminated composition (
) having two sheets (
) formed from a polymer and positioned adjacent one another to form a fluid passage (
) therebetween. The outside surfaces (
) of the sheets (
) are permeable to allow fluid flow from the outside surface (
) to the fluid passage (
). The outside surface (
) of the laminated composition (
) includes a plurality of embossed islands spaced from one another to define feed pathways (
) around and between the embossed islands.
