Abstract
The invention relates to a digester for a liquid medium, comprising a container, a dividing wall between two spaces, and a device for injecting gas into the lower part of one of the spaces. The gas creates an upflow of the mixture of liquid medium and injected gas in said space, and a downflow in the other space. The dividing wall is equipped with at least one device for establishing a fluid communication between the spaces, so that the fluid communication configuration is automatically varied between a first open configuration in which fluid can flow freely from one space to the other, and a second closed configuration in which the flow of fluid is blocked fully or partially by the aforementioned device.
