1. A separation device comprising:
a separation module comprising:
a separation membrane separating an interior of the separation module into a retentate compartment and a permeate compartment;
the retentate compartment includes:
at least one retentate channel disposed within the retentate compartment;
a feed port fluidly coupled to the at least one retentate channel and disposed adjacent a first end of the retentate compartment; and
a retentate port fluidly coupled to the at least one retentate channel, disposed opposite the first end and disposed adjacent a second end of the retentate compartment;
the permeate compartment includes:
at least one permeate channel disposed within the permeate compartment;
a permeate port fluidly coupled to the at least one permeate channel;
a retentate collector fluidly connected to the retentate port;
a feed reservoir fluidly coupled to the feed port;
a permeate reservoir fluidly coupled to the permeate port;
a fluidic gate disposed between the feed reservoir and the separation module;
a vent disposed adjacent the retentate port and adjacent the second end of the at least one retentate channel;
wherein the vent is a flooded phobic vent and is disposed in one of:
the separation module between the retentate compartment and the permeate compartment; and
outside the separation module coupled between the retentate port and the permeate port; and
a pressure differential source applied across the separation module.
