A system for supporting fluid-treatment media above a lower surface that reduces media clogging and head loss in granular fluid-treatment media systems by providing a layered porous plate. The porous plate can have multiple layers of fine sized and coarse sized pores. The porous plate is positioned between the media and the filter bottom. The system for supporting fluid-treatment media is securely anchored to the infrastructure of the underdrain system thereby inhibiting media penetration of the filter bottom and avoiding seal failures. The infrastructure can be air lateral piping fitted beneath the underdrain blocks of the support system. The anchors can be secured to pipe clamps circumscribing the air laterals.

La présente invention a pour objet un système de support destiné à maintenir des médias de traitement de fluide au-dessus d'une surface inférieure, et, grâce à l'adjonction d'une plaque poreuse stratifiée, de réduire le colmatage et la perte de charge des systèmes de média granulaire de traitement de fluide. Cette plaque poreuse peut être constituée de multiples couches à petits ou à gros pores. Elle est placée entre le média et le fond du filtre. Ledit système support du média de traitement de fluide est solidement fixé à l'infrastructure du système de drainage souterrain, ce qui empêche le média de fluide de pénétrer dans le fond du filtre tout en évitant les fuites au niveau des garnitures. L'infrastructure peut être dotée d'un canal secondaire d'air placé sous les blocs de drainage souterrain du système de support. Les attaches peuvent être fixées aux brides de fixation qui entourent les canaux secondaires d'air.
