Abstract

In a flotation plant for stock recovering and liquid clarification particularly for paper mill effluents, the rotatable equipment (3) is mounted on a hollow central column (38) and is provided with a annular concentric walls (2 min ,22) fastened thereto, a blade (7), inlet means (31-32) for the liquid (11) to be treated connected to the central column (38), outlet means (30,30 min ) connected to the outer wall (2 min ), means (71) for receiving and dropping the floating stock (4) and for bridging it to the space 22 between the inner wall (22) and the column (38) and possibly a bladed wheel (8) to increase the dropping collection of stock 4.
