Abstract

La présente invention concerne un procédé et un dispositif de traitement de l'eau. Dans ledit procédé, le décrassage du filtre (1) s'effectue par de l'air comprimé à contre-courant à l'intérieur du filtre, pendant que se produit simultanément l'aération du puits concerné ou du dépôt d'eau intermédiaire (7). Cet espace d'eau sert en même temps d'espace fonctionnel pour le processus biologique, pendant que les masses ajoutées ou les sédiments féculents s'étant formés dans le dispositif servent de milieu de culture pour le traitement de l'eau et pour le fonctionnement du dispositif. Le dispositif de la présente invention est constitué par un filtre (1) qui est destiné à être placé sur le côté non pressurisé (7) du système d'approvisionnement en eau et qui contient en plus d'un filtre mécanique également un agent biologique ou chimique ou toute autre substance de filtration active (2).
