Title
(DE) FILTERMATERIAL UND VERFAHREN ZUR ENTFERNUNG VON OZON AUS GASEN UND FLÜSSIGKEITEN
(EN) FILTER MATERIAL AND PROCESS FOR REMOVING OZONE FROM GASES AND LIQUIDS
(FR) MATERIAU DE FILTRAGE ET PROCEDE D'ELIMINATION DE L'OZONE CONTENU DANS DES GAZ ET DES LIQUIDES
Abstract
(DE)
Die Erfindung bezieht sich auf ein Filtermaterial sowie ein Verfahren zur Entfernung von Ozon aus Gasen und Flüssigkeiten, bei welchem ein Gasstrom oder eine Flüssigkeit mit einem Filtermaterial aus einem ungesättigten Cycloolefinpolymer oder -copolymer in Kontakt gebracht wird. Das Filtermaterial kann bei allen ozonhaltigen Gasströmen und Flüssigkeiten verwendet werden. So findet es beispielsweise Anwendung bei der Beseitigung des bei der Sterilisation verwendeten oder aus einem Kopiergerät entstandenen Ozons, ferner zur Entfernung und Unschädlichmachung von Ozon in Flüssigkeiten.
(EN)
A filter material is disclosed, as well as a process for removing ozone from gases and liquids. A gas flow or a liquid are contacted with a filter material made of an unsaturated cycloolefin polymer or copolymer. The filter material is suitable for all ozone-containing gas flows and liquids. It is for example useful for eliminating ozone used for sterilisation purposes or ozone generated by copying machines, and for removing and neutralising ozone in liquids.
(FR)
L'invention concerne un matériau de filtrage et un procédé d'élimination de l'ozone contenu dans des gaz et des liquides. Selon ce procédé, un courant de gaz ou un liquide sont mis en contact avec un matériau de filtrage qui contient un polymère ou un copolymère de cyclo-oléfine insaturée. Le matériau de filtrage est utilisable dans tous les courants de gaz et de liquides contenant de l'ozone. Il est par exemple utile pour éliminer l'ozone utilisé à des fins de stérilisation ou l'ozone généré par un copieur, ainsi que pour éliminer et neutraliser l'ozone contenu dans des liquides.
