METHOD AND INSTALLATION FOR DISINFECTION OF FLUID MEDIA Russian patent published in 1995 - IPC

FIELD: sterilization of air or aqueous media by ultraviolet radiation. SUBSTANCE: method involves irradiation with a source of ultraviolet radiation in pulsating mode. Irradiation is carried out at a frequency not over 10 Hz in a spectral range of 180-400 nm. The installation comprises a casing with a reflecting coating and pulsators accommodated in the casing, their total length corresponding to a relation L ≥ U/ν where U flow velocity of fluid medium; n pulse frequency. The total number of pulsators is M (0.02 0.2) V, where V volume of installation casing. EFFECT: improved functional and operating characteristics. 2 cl, 2 dwg, 1 tbl
