Patent

CA 2321885

The invention concerns a method for controlling the integrity of hollow fibre filtering modules and detecting leaks of the fluid treated through an entirely or partially ruptured fibre, characterised in that it consists in: detecting the noise caused by the passage of a fluid through a ruptured fibre; amplifying the resulting noise signal; and comparing the resulting amplified signal to a noise threshold level, in the same range of frequencies, characteristic of a module in perfect condition, said comparison enabling to detect whether the module is in perfect condition or not.

Procédé de contrôle de l'intégrité des modules de filtration à fibres creuses et de détection de fuites du fluide traité au travers d'une fibre complètement ou partiellement cassée caractérisé en ce qu'il consiste à: détecter le bruit occasionné par le passage du fluide au travers d'une fibre rompue; amplifier le signal bruit ainsi obtenu; et, comparer le signal amplifié ainsi obtenu à un niveau de bruit seuil, dans la même gamme de fréquences, caractéristique des modules intègres, cette comparaison permettant de détecter si le module est ou non intègre.
