Inventor: ANDREWS CRAIG
IPC: A61L2/20
Filed: 1998-11-05
Abstract: A method and apparatus for producing purified or ozone enriched air to remove contaminants from fluids is accomplished by exposing an air stream from a surrounding area to ozone generating ultra-violet (UV) radiation to generate ozone in a system ozone chamber. The ozone chamber is configured to reduce through-flow velocity and provide time for the ozone to mix with the air and oxidize contaminants. The air stream subsequently enters a germicidal chamber and is exposed to germicidal UV radiation to destroy bacteria and ozone in the air stream resulting in sterilized air. The system may further include an additional germicidal chamber that exposes an air stream to germicidal radiation prior to treatment within the ozone chamber, or the system may be configured to include a baffling arrangement to control air through-flow velocity, or may be implemented by a cartridge arrangement. The system may further be configured for installation within a wall or ceiling, or may be utilized to remove contaminants from and/or ozonate liquids. In addition, the air sterilization systems may be utilized within air treatment systems to remove contaminants from an air stream within these systems.
