Zusammenfassung:	An arrangement of troughs is disposed above a liquid/distribution tray in a counter-current column for collecting and mixing liquid from an upper exchange portion prior to distribution onto the tray. The arrangement includes duct-like troughs each of which has a base with a closed first part and a second part with at least one outlet for liquid. As a result, the liquid trickled into each trough is mixed transversely prior to being expelled onto the distributor tray thus levelling out any differences in concentration along the length of the trough.
