ABSTRACT:
An apparatus for sterilizing fluids comprises a radiation chamber which comprises a source of ultraviolet radiation; a housing surrounding said source and including an inner casing permeable to ultraviolet radiation and bounding a channel with said source, and an outer casing surrounding said inner casing and forming a treating space therewith; a conduit for conducting a stream of gas containing molecular oxygen through said channel for exposure to said ultraviolet radiation to produce an ozone-enriched gas; a conduit for conducting a fluid through said treating space so as to become sterilized by the ultraviolet radiation; and a conduit for introducing at least a portion of said ozone-enriched gas from said channel into said treating space to become united with said fluid, whereby said introduced portion of ozone-enriched gas is again exposed to ultraviolet radiation in order to produce an increased content of ozone in said ozone-enriched gas and an additional sterilizing effect is produced in said fluid. A process for sterilizing fluid is also provided. According to this process, a fluid and a gas which contains molecular oxygen are irradiated with ultraviolet radiation and are then mixed together in order to produce an additional sterilizing effect.
