Abstract: A device and method for enriching and/or depleting substances in a liquid is disclosed. An exemplary device comprises a membrane module that consists essentially of concentric elements and that has a separation element in which the substance to be enriched and/or depleted is carried, and whereby the liquid is carried outside of the separation element. The exemplary device also comprises a drive module that encompasses a drive unit for driving a conveying element that conveys the liquid, the drive unit having a radial magnetic coupling for a central impeller located on the inside. The exemplary device further comprises a conveying module for conveying the liquid through the device, housing the conveying element, whereby the drive module is adapted to be inserted into and removed from the membrane module with a liquid-tight closure. The exemplary device further an oxygenator having an outside fiber bundle and an inside fiber bundle.
