Abstract

The invention relates to an apparatus (3-40, 4-40, 5-40) and a method for purifying a material flow (4-35, 4-36, 5-35, 5-36), particularly air, gas or liquid. It comprises a first source of radiation in form of a lamp (3-50, 4-50, 5-50) generating a first UV radiation containing at least one of wavelengths of approximately 187 nm and 254 nm, and a housing surrounding the lamp (3-50, 4-50, 5-50) and confining a flow path between the lamp (3-50, 4 -50, 5-50) and the housing for the fluid to be purified by said first radiation. In the invention, furthermore, a second source of radiation is provided in form of a layer (3-25, 4-37, 4-38) containing fluorescent component and arranged apart from the lamp (3-50, 4-50, 5-50), said fluorescent component being reactive to said first UV radiation emitted by the lamp to generate a second UV radiation containing at least one wavelength in the range of about 300 to 385 nm, and a catalytic material reactive to the second UV radiation to produce photo catalytic oxidation, preferably hydroxyl radicals, to the flow path.
