In a plant a liquid is treated while flowing through a tube (10) of flexible material, which in turn is moved in the flow direction of the liquid through first and second channels (1, 2) coupled in series. In the channels (1, 2) the flexible tube (10) is surrounded by liquid flowing in the same direction as the liquid within the flexible tube (10). The flexible tube (10) is transferred from one of the channels to the other through a passage in a transferring device (3), which passage has a cross-section which as to form and size substantially coincides with the cross-section of the flexible tube (10), when this is situated in the passage. While the flexible tube is moved between said one channel (1) and the passage, it is surrounded by perforated walls forming a transferring channel, liquid around the flexible tube being gradually discharged from the transferring channel along a substantial part of its extension. |
