Abstract

La présente invention concerne un filtre à faisceau de brins de fibres caractérisé en ce que l'intérieur d'un logement est rempli avec des faisceaux de brins de fibres dans lesquels l'intérieur d'un filet est rempli avec un ou plusieurs flotteurs et une pluralité de brins de fibres et, pendant la filtration, l'efficacité de filtration est accrue étant donné que les pores entre les brins de fibres deviennent plus petits tandis que les faisceaux de brins de fibres supérieurs sont comprimés en raison de la flottaison vers le haut des faisceaux de brins de fibres incorporant les flotteurs du fait de la flottabilité et, durant le nettoyage, l'efficacité de nettoyage est accrue étant donné que les brins de fibres sont desserrés en raison du mouvement libre des faisceaux de brins de fibres du fait du fluide interne et de l'air.
