Abstract

Installation de traitement de liquides, comprenant un dispositif de décantation dans lequel le liquide brut monte pendant la filtration, ainsi qu'une cuve de filtrage comportant à proximité du fond un plateau à tuyères sur lequel repose la couche filtrante et sous lequel se trouve dans le fond une chambre collectrice et d'évacuation du filtrat. Le dispositif de décantation 5 est disposé dans la chambre de submersion 4 se trouvant au-dessus de la couche filtrante 3. Application en particulier aux installations de filtration des eaux usées afin de réduire l'encombrement d'ensemble.
