<p>A plant contains a tank (1) divided by a vertical separation wall (6) and annular support (7) of a cylindrical filter insertion (9) into an entrance region (4), which is connected with an inner area (8) via a middle orifice (24) in a horizontal annular support (7), and, into an exit region (5) enclosing each of the cylindrical filter insertions (9) vertically arranged on the horizontal annular support (7) to which the said insertions are firmly and water-tightly attached by their lower edges. A rotary exhaust mechanism (12), which is arranged in the inner area (8) of the cylindrical filter insertions (9), has at least one exhaust nozzle (14) attached to a hollow shaft (13) positioned in an axis of the cylindrical filter insertions (9) and interconnected with an underpressure source.</p> |
