Abstract: The invention concerns a digester for performing a sludge methanization treatment for the purpose of generating biogas and a digestate, the digester comprising a device (32) for discharging foaming and/or floating matter (16) from the digestate (12), comprising: a first tank (33) delimited by a first wall (100) having a first height (h1), the first tank (33) being intended to be fed with digestate (12) and with foaming and/or floating matter (16) from a volume of material (14) by overflow over the first wall (100); a second tank (34) connected to the atmosphere and sited outside the enclosure (13) of the digester, comprising: a first zone (35) delimited by a second wall (103) having a second height (h2); and a second zone (36) in communication with the reservoir (19); a conduit (37) connecting the first tank (33) via a first orifice (101) to the first zone (35) of the second tank (34) via a second orifice (102) positioned higher than or level with the first orifice (101), the first zone (35) being intended to

Abstract: Embodiments of a large container may include a container base and a circumferential container wall. An upper end of the wall is closed by a container cover in the form of a metal disc. An annular, circumferential support element is secured at an upper end region of the wall. The disc spans the upper open end of the container wall. A lower side of the disc is welded to the support element and/or to the upper end region of the container wall by a continuous first welding seam. An upper side and/or an edge of the disc is welded to the support element by a continuous second welding seam. The first and second weld seams have respective first and second roots which merge into one another or at least come together.

Abstract: The present invention relates to a buffer store comprising a closed vessel housing for accommodating a storage fluid, in particular water, wherein the vessel housing has at least one inlet opening, for the filling of the vessel housing with the storage fluid, and at least one equalization opening, which fluidically connects the vessel housing to the surroundings and permits a fluidic equalization with the surroundings. According to the invention, a gas-tight cover is also provided in the interior of the vessel housing, which cover is capable of reliably protecting the storage fluid against mixing with other fluids, for example the ambient air.
