Abstract

Dispositif d'aération pour un bassin rempli de liquide comportant une conduite d'entrée d'air (5) débouchant dans un distributeur (2) auquel sont raccordées des conduites de distribution (4) pour l'amenée d'air dans le bassin, des fentes de passage étant disposées verticalement entre les conduites de distribution (4), ces dernières étant fixées à leurs extrémités opposées à une traverse arrière (3), le distributeur d'air (2) et la traverse arrière (3)étant reliés par une traverse de liaison (1) formant un tuyau creux disposé entre les conduites de distribution (4). La traverse de liaison (1) est disposée symétriquement contre les conduites de distribution (4), son intérieur étant isolé de l'intérieur du distributeur (2) et de celui de la traverse arrière (3). L'intérieur du distributeur d'air (2) est relié par les conduites de distribution (4) à l'intérieur de la traverse arrière (3). Le cadre du dispositif avec la partie supérieure (12'') comporte au moins un stabilisateur (12) dont la partie inférieure est reliée au fond du bassin.
