1. A fluid processing system comprising:

  • a fluid circuit including a filter with a membrane;

    the fluid circuit further including blood and non-blood circuits separated from each other by the membrane;

    the blood circuit having an inlet and an outlet connected to a connector assembly,the connector assembly including a first fluid passage coupled to the outlet of the fluid circuit and a second fluid passage that does not communicate with the first fluid passage and is coupled to the inlet of the fluid circuit,the first and second fluid passages being housed in a common assembly constructed for coupling to a container, which is filled with sterile fluid and serves as a fluid source, so as to form a loop such that fluid is circulated by the connector assembly through the container in the loop, thereby collecting in the container air residing in the blood circuit,at least a portion of the loop including the blood circuit from the inlet to the outlet,wherein the membrane is arranged at a portion of the blood circuit between the blood circuit inlet and the blood circuit outlet.
