Membrane device for filtering or enriching constituent from fluid, has membrane surface which is permeable to constituent of fluid to be filtered, where adjusting device is provided for varying size of membrane surface

摘要

The membrane device (10) has a membrane surface which is permeable to a constituent of a fluid to be filtered, where an adjusting device (12) is provided for varying the size of the membrane surface which is supplied by the fluid. The membrane surface has multiple membrane surface components, where multiple membrane device segments (18a,18b,18c) are associated with the membrane surface components. An independent claim is included for a method for filtering or enriching a constituent from a fluid.
