1. A fluid circuit comprising:

  • a membrane having a first side, a second side opposite said first side, and a pore extending from said first side to said second side;

    a first channel containing fluid extending along said first side of the membrane;

    a second channel containing fluid extending along said second side of the membrane and crossing said first channel; and

    an electrical source in electrical communication with at least one of said first fluid and second fluid for selectively developing an electrical potential between fluid in said first channel and fluid in said second channel thereby causing at least one component of fluid to pass through the pore in the membrane from one of said first channel and said second channel to the other of said first channel and said second channel.
