Abstract
(DE)
Das beschriebene Verfahren und das Filter dienen zur Entfernung von organischen Stoffen und Ozon aus Gasen. In dem Verfahren wird ein Gas von Ozon und organischen Stoffen dadurch befreit, daß das Gas zunächst mit einem Ozon-bindenden Polymer und dann mit Aktivkohle in Kontakt gebracht wird. Das Filter besteht aus einer Filtereinheit, die ein Ozon-bindendes Polymer enthält und einer zweiten Filtereinheit mit Aktivkohle.
(EN)
The invention concerns a process and filter for removing organic substances and ozone from gases, in which the gas is first brought into contact with an ozone-binding polymer and then with activated carbon. The filter consists of one filter unit containing an ozone-binding polymer and of a second filter unit containing activated carbon.
(FR)
L'invention a pour objet un procédé et un dispositif de filtration servant à l'élimination de matières organiques et de l'ozone dans des gaz, procédé selon lequel le gaz est débarrassé de l'ozone et des matières organiques en étant amené en contact tout d'abord avec un polymère capable de fixer l'ozone, puis avec du charbon actif. Le dispositif de filtration comprend un premier ensemble filtrant renfermant le polymère fixant l'ozone, et un deuxième ensemble filtrant renfermant le charbon actif.
