Abstract

Un dispositif de filtration (10) de l'eau par écoulement, alimenté par différence de niveau, comprend une chambre (11) abritant un filtre (30, 80) en spirale qui contient un matériau biocide, et une chambre de fixation annulaire. Plusieurs disques séparateurs poreux, un volume de milieu filtrant (64) et une membrane (70) à kystes sont positionnés sous le filtre en spirale et la chambre de fixation. Le dispositif (10) est efficace pour réduire de manière significative le nombre de bactéries, de virus et de kystes présents dans l'eau filtrée. Sa conception, à échelle variable, permet de l'utiliser dans les systèmes municipaux de traitement des eaux et dans d'autres systèmes. La configuration du trajet d'écoulement peut être un canal étroit d'une largeur minimale, doublé d'un matériau granulaire actif, qui améliore le rendement de la filtration et du processus de traitement, tout en maintenant à son minimum la résistance à l'écoulement. La géométrie en spirale ou hélicoïdale se prête à une disposition compacte quand la place est limitée. Le canal fluidique doublé de matériau granulaire brise le flux laminaire et crée un environnement inhospitalier pour la croissance des contaminants bactériens, comparable au biofilm que l'on trouve et décrit typiquement dans les systèmes de traitement de l'eau en dentisterie.
