1. A separator device for separating a mixture of gas entrained in water comprising:

  • a hydrophilic porous membrane;

    a hydrophobic porous membrane;

    enclosure means forming a fluid chamber including portions of said membranes and means spacing said membranes parallel to each other including a spacer member extending around said portions;

    input means for directing said mixture to said chamber and including a chamber extending about the spacer and also including a plurality of openings extending through said spacer into the fluid chamber;

    means for creating a pressure differential across said portion of said hydrophilic porous membrane so as to cause outward flow of said water; and

    means for creating a pressure differential across said portion of said hydrophobic porous membrane and for creating an outward movement of said gas without overcoming the negative capillary forces which form a water barrier, whereby selective transfer of gas and water through said portions produces separation of said mixture in both zero g and one g environments.
