METHOD OF LIQUID DECONTAMINATION BY UV-RADIATION AND DEVICE TO THIS END Russian patent published in 2010 - IPC C02F1/32 A61L2/10 

FIELD: process engineering.

SUBSTANCE: invention relates to decontamination of water or any other fluid. Proposed method consists in irradiating stationary or moving fluids by UV-radiation of semiconductor LEDs. Said radiation is introduced into fluid to be decontaminated with the help of flexible quartz waveguide is bent many times on radius r ≤ R_d, where R_d is band radius whereat conditions of complete disturbance of internal reflection for operating mode in the case of single-mode fiber or modes that carry major fraction of radiation in the case of multi-mode fiber. Proposed device comprises at least one UV-range LED and at least one flexible optical waveguide bent as described above.

EFFECT: reduced power consumption at sufficient radiation dose.
