Filtration chamber consisting of a cylindrical vessel having a bottom plate (1a) forming a support for the filtering system (11), this latter comprising a filter sheet (11a) and a filter netting bed (11b), both anchored to the bottom plate (1a). The filter sheet (11a) and the filter bed (11b) are fixed at their periphery onto an anchor ring (10), provided with a bayonet system (10a, 1c) for rapidly locking it onto the bottom support plate (1a). The filter sheet (11a), in the form of a punched plate or of a gate, and the filter bed (11b), in the form of a wire net, are fixed to the anchor ring (10), along its entire periphery, by welding. Three O-Ring type toroidal sealing gaskets (13, 15, 16) are positioned between opposed horizontal surfaces-of the bottom plate (1a), of the anchor ring (10), and of a rib (14) of the chamber wall (2)-so that the operation to for closing the bottom (1) of the chamber causes the simultaneous tightening of all the gaskets.
