Abstract

The thickening process takes place in three stages, where in the sedimentation vessel 8 a partial dewatering takes place under pressure. To increase the dewatering effect, a removal system for separated water can be installed in the sedimentation vessel 8 in the form of the collection shaft 20 with the attached hood profiles 22 which are open in a downward direction. The previously dewatered sludge is subsequently led into the aerating vessel 11 and there, similarly under pressure, aerated with gas in the form of fine bubbles. This charging with gas in fine bubble form takes place near the base of the vessel 11. The incorporation of gas into the sludge can also take place as a result of intensive mixing of the sludge/gas mixture by means of a mechanical agitator. In the final phase, the previously dewatered sludge aerated under pressure in vessel 15 is further dewatered by the action of the flotation effect. The flotation takes place under atmospheric pressure or even under reduced pressure.
