Abstract

L'invention concerne un système et un dispositif qui sont conçus pour le traitement d'eaux d'égout, d'eaux usées sanitaires et municipales, d'écoulements d'eaux de pluie, d'écoulements agricoles et toute autre eau biologiquement contaminée pour répondre aux exigences de retrait de substance nutritive. Ce système et ce dispositif ne nécessitent pas d'ajout chimique et d'agitation physique. Le procédé de traitement de ce processus retire un chargement de DBO (demande biochimique en oxygène), abaisse les TSS (matières en suspension) à des limites acceptables, convertit l'ammoniac en nitrates et les nitrates en azote. L'invention fournit une étape de traitement dans laquelle les composés d'azote et d'oxygène sont absorbés. Dans tout le processus de traitement de la présente invention, les bactéries coliformes et toute autre bactérie sont détruites, de même que des virus, des champignons et des parasites.
