| abstract |
The invention describes a device (1) for at least partially separating a solvent from a solution (6), comprising at least one membrane filter unit (2) which has a solution feed element (8), a solvent outflow and a concentrate outlet (5) for a concentrate produced from the solution (6). Upstream of the solution feed element (8), at least one unit (7) is arranged on the membrane filter device (2) for generating a rotating or swirling flow in the solution (6). Optionally, magnets (24), a laser (25) and/or a gas suction device (26) are arranged on the device (7). Said device (7) can be operated in the bypass flow. |
