  • Fume treatment method and apparatus using ultraviolet light to degrade contaminants
    Patent number: 8002881
    Abstract: An ultraviolet treatment chamber for treating exhaust streams, particularly those containing organic particulates, utilizes ultraviolet light energy very efficiently. This is done by setting up a circulating flow in a treatment plenum so that all of the effluent experiences a substantially uniform residence time without the need for baffles or other flow controllers that would block the ultraviolet light.
