Abstract
The invention relates to a filter material and to a process for removing ozone from gases and liquids, in which a gas stream or a liquid is brought into contact with a filter material made of an unsaturated cycloolefin polymer or cycloolefin copolymer. The filter material can be used with all ozone-containing gas streams and liquids. Thus, for example, it is used in the removal of the ozone used in sterilization or formed by a copier machine, in addition for removing and detoxifying ozone in liquids.
Claims17
A filtering system comprising:
- means for bringing a fluid stream containing ozone into contact with a filter material,
- a filter material for reducing the content of ozone in said fluid stream containing ozone, said filter material comprising polymerized unsaturated cycloolefin, and means for recovering a purified fluid stream from said filtering system.
A process for reducing the content of ozone in an ozone-containing fluid, which comprises:
- bringing the ozone-containing fluid into contact with a polymerized unsaturated cycloolefin and removing an amount of ozone from said ozone-containing fluid.
An air filtration system comprising:
- means for bringing an ozone-containing air stream into contact with a filter material,
- a container for holding filter material and for permitting said air stream to pass through said container without interference, said container having an exit for the purified air stream, and
- within said container, a filter material for reducing the content of ozone in said air stream, said filter material consisting essentially of a polymerized unsaturated cycloolefin.
