System and method for filtration and/or dilution of fluids

A system comprising a filter device for filtration of fluids, wherein said filter device comprises:

• a housing having a first end and a second end and defining a fluid chamber extending between the first end and the second end;
• a first lid provided at the first end of the housing and comprising a first fluid port, a first compartment, a second compartment and a first internal separating wall separating the first compartment from the second compartment;
• a second lid provided at the second end of the housing and comprising a second fluid port and a second lid compartment, the second lid compartment representing a single compartment not being separated by internal separating means;
• a plurality of hollow fibers arranged within the housing, wherein each of the plurality of hollow fibers comprises a semi-permeable membrane and defines a fluid channel extending longitudinally through an interior of the respective hollow fiber;
• a first sealing means which separates the fluid chamber from the first compartment and the second compartment, the first sealing means having a first longitudinal end facing away from the second lid;
• a second sealing means which separates the fluid chamber from the second lid compartment, the second sealing means having a second longitudinal end facing away from the first lid;
• a fourth fluid port and a fifth fluid port both provided at the fluid chamber and located between the first longitudinal end of the first sealing means and the second longitudinal end of the second sealing means;
• wherein the first fluid port is arranged at the first compartment, wherein the second fluid port is arranged at the second lid compartment,
• wherein the plurality of hollow fibers comprises a first group of fibers and a second group of fibers, wherein each hollow fiber of the first group of fibers extends from the first compartment through the fluid chamber to the second lid compartment and fluidly connects the first compartment with the second lid compartment via the fluid channels extending through the interior of each hollow fiber of the first group of fibers for filtering a first fluid, and wherein each hollow fiber of the second group of fibers extends from the second compartment through the fluid chamber to the second lid compartment and fluidly connects the second compartment with the second lid compartment via the fluid channels extending through the interior of each hollow fiber of the second group of fibers, and wherein the fluid chamber does not have provided therein a wall to separate the first group of hollow fibers and the second group of hollow fibers, and
• wherein the fourth fluid port and the fifth fluid port are fluidly connected to one another and both in fluidic communication with an exterior of both the hollow fibers of the first group of fibers and the second group of fibers via the fluid chamber.

• a plurality of hollow fibers arranged within the housing, wherein each of the plurality of hollow fibers comprises a semi-permeable membrane and defines a fluid channel extending longitudinally through an interior of the respective hollow fiber;
• a first sealing means which separates the fluid chamber from the first compartment, the first sealing means having a first longitudinal end facing away from the second lid;
• a second sealing means which separates the fluid chamber from the second lid compartment, the second sealing means having a second longitudinal end facing away from the first lid;
• a third fluid port and a fourth fluid port both provided at the fluid chamber and located between the first longitudinal end of the first sealing means and the second longitudinal end of the second sealing means;
• wherein the first fluid port is arranged at the first compartment, wherein the second fluid port is arranged at the second lid compartment,
• wherein the plurality of hollow fibers comprises a first group of fibers and a second group of fibers, with each hollow fiber of the first and the second group of fibers comprising a first end and a second end, wherein each hollow fiber of the first group of fibers extends via its respective first end from the first compartment through the fluid chamber to, via its second end, the second lid compartment, and, for directing a first fluid, fluidly connects the first compartment with the second lid compartment via the fluid channels extending through the interior of each hollow fiber of the first group of fibers, and wherein each hollow fiber of the second group of fibers substantially extends, via its respective first end, from the first compartment through the fluid chamber to, via its respective second end, the second lid compartment, wherein each hollow fiber of the second group of fibers at its respective first end is closed, so that there is no fluid connection between the first compartment with the second lid compartment through the second group of fibers, with the fluid channels extending from the closed first end through the interior of each hollow fiber of the second group of fibers to the second lid compartment, and
• wherein the fourth fluid port and the fifth fluid port are fluidly connected to one another and both in fluidic communication with an exterior of both the hollow fibers of the first group of fibers and the second group of fibers via the fluid chamber.
