Method and system for recovering fluid

A method for recovering filtered fluid retained in a filter system including a filter device comprising a housing having an inlet and an outlet defining a filtration flow path between the inlet and the outlet, and a porous filter medium across the filtration flow path, the porous medium having an upstream side and a downstream side;

• the system also including a filtered fluid receiving container arranged downstream of the outlet, and a fluid flow path between the outlet and the filtered fluid receiving container, the method comprising:
• (a) filtering fluid by passing the fluid along the filtration flow path through the filter device and along the fluid flow path into the filtered fluid receiving container, including displacing, by the filtered fluid, sterile air and/or sterile gas into the filtered fluid receiving container, wherein a volume of filtered fluid is retained in the housing between the downstream side of the porous filter medium and the outlet;
• and,
• (b) allowing the sterile air and/or the sterile gas to pass from the filtered fluid receiving container along the fluid flow path and through the outlet into the housing of the filter device, and displacing retained filtered fluid into the filtered fluid receiving container.

A system for recovering filtered fluid comprising:

• (a) a filter device comprising a housing having an inlet and an outlet defining a filtration flow path between the inlet and the outlet, and a porous filter medium across the filtration flow path, the porous medium having an upstream side and a downstream side;
• (b) a filtered fluid receiving container arranged downstream of the outlet, and
• (c) a fluid flow path between the outlet and the filtered fluid receiving container;
• wherein the filtered fluid receiving container can be arranged at an angle of in the range of about 10° to about 30° above a horizontal plane, and subsequently arranged at an angle in the range of about 10° to about 30° below the horizontal plane.
