Abstract

The invention relates to a method for separating the liquid part from the suspended matter in a sludge supplied in a continuous flow at a flow rate of QEB=V/hour. The flow is divided into at least two partial flows which are sprayed on top of one another into a sealed chamber of volume v<V/20, simultaneously injecting air therein at a flow rate d, said chamber being kept under overpressure conditions. The suspended matter of the thus treated flow is then left to decant in a collection container, with the cake or solid part falling to the bottom and separating from the liquid part which is continuously discharged.
