The bottom portion of the flotation area comprises: a perforated floor () located above an apron (R), a floated-water discharge being provided under the floor and leading to an outlet system (); and at least two separate channels () which are oriented in the direction of flow of the water and are provided under the floor (), and under optional structures (w) extending from the floor, to a point upstream of the outlet system (). The downstream end () of the channels is open and located above the floor level, and a discharge means (V) is provided, for each channel, at the end of the downstream bottom portion of said channel.
