Hollow fiber module

A hollow fiber module comprising a plurality of hollow fiber cartridges, wherein

• a. each hollow fiber cartridge comprises a bundle of semi-permeable hollow fibers, said bundle being surrounded by a shell extending longitudinally along the length of the bundle and potted at both ends in a resin, thereby defining a lumen side volume for the treatment of a first solution and a shell side volume for the treatment of a second solution such that the first solution or the treated first solution and the second solution or the treated second solution are not in fluid communication other than across the semi-permeable hollow fibers, said shell being provided with a first port for receiving the second solution to be treated in the shell side volume and a second port for discharging the treated second solution only,
• b. a first end cap comprising an inlet for the first solution and an end cap distributor for distributing the first solution to a first end of each of the hollow fiber cartridges,
• c. a second end cap comprising an end cap collector for collecting the treated first solution from a second end of each of the hollow fiber cartridges and an outlet for the treated first solution,
• d. a first connector comprising an inlet for the second solution and a connector distributor for distributing the second solution to the first port of each of the hollow fiber cartridges, and
• e. a second connector comprising a connector collector for collecting the treated second solution from the second port of each of the hollow fiber cartridges and an outlet for the treated second solution,
• wherein the first and second end caps are connected at their perimeter with a cover tube, said cover tube enclosing the plurality of cartridges in the longitudinal direction,
• wherein the first or the second end cap is integral with the first or the second connector, and
• wherein the connector distributer or connector collector comprises a second solution chamber delimited by a first tube plate with apertures for accommodating the plurality of hollow fiber cartridges, a second tube plate accommodating the ends of the plurality of hollow fiber cartridges and the end cap, said first and second tube plates being axially positioned on either side of the ports of the plurality of hollow fiber cartridges relative to the longitudinal extent of the cartridges such that the second solution chamber is liquid-tight.
