Title
(EN) RAINWATER FILTRATION SYSTEM
(FR) SYSTEME DE FILTRATION DES EAUX PLUVIALES
Abstract
(EN) The present invention relates to a rainwater filtration system comprising at least one rigid frame delimiting a volume having at least one downstream face (7), one upper face (5), one lower face (6) and two side faces (8), said at least one frame being capable of being placed on and attached to said bottom (12) and supporting at least one filter (2) which comprises on its upper face (5) an opening (3) capable of receiving said rainwater (10) loaded with waste (13), and said at least one frame being arranged and dimensioned in such a way that, in the event of a high flow rate, the part of the rainwater that does not pass through said opening (3) flows over this frame; according to the invention, all the faces (5, 6, 7 and 8) of this at least one rigid frame are closed by plates, which are themselves rigid, thus constituting a cage (1) and leaving an open part on the upper face (5) thereof, and at least the plate (27) closing the downstream face (7) of the cage (1) is perforated and forms a filter capable of retaining the waste (13) and through which the rainwater entering through said opening (3) can flow.
(FR) La présente invention a pour objet un système de filtration des eaux pluviales comprenant au moins un cadre rigide délimitant un volume ayant au moins une face aval (7), une face supérieure (5), une face inférieure (6) et deux faces latérales (8), lequel au moins cadre étant apte à être posé et fixé sur le dit fond (12) et supportant au moins un filtre (2) qui comporte sur sa face supérieure (5) une ouverture (3) apte à recevoir lesdites eaux pluviales (10) chargée de déchets (13), et lequel au moins cadre étant disposé et dimensionné de telle façon qu'en cas de fort débit la partie des eaux pluviales ne passant par ladite ouverture (3) s'écoule par-dessus ce cadre; suivant l'invention toutes les faces (5,6,7 et 8) de ce au moins cadre rigide sont fermées par des plaques, elles-mêmes rigides, constituant ainsi une cage (1) et laissant sur la face supérieure (5) de celle-ci une partie ouverte, constituant la dite ouverture (3), et au moins la plaque (27) fermant la face aval (7) de la cage (1) est ajourée et forme un filtre apte à retenir les déchets (13) et à travers lequel les eaux pluviales rentrant par la dite ouverture (3) peuvent s'écouler.
