A filter for removing bacterial contaminants from effluents, wherein filtering means comprise two mutually facing and spaced apart networks of pipes connected to the filter inlet and the filter outlet for distribution and drainage (14) respectively, and provided with perforations distributed lengthwise along the transverse walls of said pipes. Filter means (16) between the two pipe networks (13, 14) consist of a layer of sand with a size distribution curve within the range defined by A.F.N.O.R. DTU no. 64-1, Ref. P16-603, and remove a substantial part of the bacterial contaminants from the effluent passing through the filter. Distribution means connected to the distribution pipe network (13) deliver the water to be treated to the filter means (16).

L'invention concerne un filtre pour la rétention de la contamination bactérienne d'effluents dont les moyens de filtration comportent deux réseaux de tuyaux respectivement de répartition et de drainage (14) associés respectivement à l'entrée et à la sortie du filtre, placés sensiblement en regard et espacés l'un de l'autre, et pourvus de perforations réparties longitudinalement dans leurs parois transversales, des moyens filtrants (16) interposés entre les deux réseaux (13; 14) se présentant sous la forme d'une couche de sable dont la courbe granulométrique s'inscrit dans le fuseau défini dans le DTU N~64-1, Réf. P 16-603 de l'A.F.N.O.R., apte à assurer la rétention d'une partie substantielle de la contamination bactérienne de l'effluent traversant le filtre et des moyens de répartition associés au réseau de tuyaux de répartition (13) et destinés à assurer une diffusion des eaux à traiter vers les moyens filtrants (16).
