Abstract

By UV irradiation of the "unclean" side of a sterile filter the useful life and effectiveness of the filter unit are considerably increased. <IMAGE>

Description

HESCHREIBUNGDESCRIPTION

ENTKEIMUNGSGERÄT für Wasser, wäßrige und andere Lösungen Die Entkeimungsfiltration von normalem, demineralisiertem and destilliertem Wasser oder von Lösungen in-e:ner sontinuierlich arbeitenden Anlage ist unter anderem auch deshalb problematisch, weil es in Abhängigkeit von der Keimbelastung mehr oder weniger schnell a. zur Verringerung der Durchflußleistung des Filters auch auf Grund des schellen Wachstums der Keime auf der Filteroberfläche und b. zum "Durchwachsen" der Keime durch das Filtermedium kommt.Disinfection device for water, aqueous and other solutions The disinfection filtration of normal, demineralized and distilled water or of solutions in-e: ner continuously operating system is problematic, among other things, because, depending on the bacterial load, a. to reduce the flow rate of the filter also due to the rapid growth of the germs on the filter surface and b. to "grow through" the germs through the filter medium comes.

Die Bestrahlung der Filteroberfläche an der Fingangsseite (~unreine" Seite) mit UV-Strahlen bewirkt gerade in diesem Bereich, in dem die Mikroorganismen sich sammeln und verweilen, zu einer Keimreduzierung und Wachstumshemmung.The irradiation of the filter surface on the entrance side (~ impure " Side) with UV rays effects precisely in this area in which the microorganisms collect and linger, to a germ reduction and growth inhibition.

Ich beantrage den Patentschutz für ein System, welches dadurch gekennzeichnet ist, daß durch die UV-Bestrahlung der keimbeladenen Seite eines Sterilfilters die Standzeit und die Effektivität der Filtereinheit beträchtlich erhöht wird.I am applying for patent protection for a system which is characterized by this is that by the UV irradiation of the germ-laden side of a sterile filter Service life and the effectiveness of the filter unit is increased considerably.

PATENTANSPRUCH Hiermit beantrage ich den Patentschutz für ein ENTKEIMUNGSGERÄT für Wasser, wäßrige und andere Lösungen, gekennzeichnet dadurch, daß durch die UV-Bestrahlung des Filtermaterials auf der unreinen" Seite, der Seite also, auf der die Mikroorganismen sich sammeln und verweilen, Keimzahl und Wachstum der Keime reduziert werden.PATENT CLAIM I hereby apply for patent protection for a disinfection device for water, aqueous and other solutions, characterized in that by UV irradiation of the filter material on the unclean "side, that is, the side on which the microorganisms are present collect and linger, the number and growth of germs are reduced. Die Standzeit und Effektivität der Serilfiltereinheit wird dadurch beträchtlich erhöht.This increases the service life and effectiveness of the Seril filter unit increased considerably.
