UV Disinfection

USHIO has used its technical experience to develop innovative light solutions for the fulfilment of UV disinfection and VUV/03 purification. USHIO’s lamps for such purposes are highly efficient and specialised for each application, e.g. lamps designed with instant-on functionality for usage at point of dispensation (POD).

Ultraviolet Germicidal Irradiation (UVGI)

UV-C wavelengths between 160 nm and 310 nm have a unique germicidal ability to provide a means of disinfection through the instant inactivation of microorganisms and pathogens such as bacteria, viruses, and protozoa.

Non-ionising radiation, like ultraviolet light, has a mutagenic effect on these organisms by exciting the molecules at the very core of their DNA and RNA. The catastrophic destruction of the cell walls renders them unable to reproduce or infect and, in some cases, kills them.

Able to neutralise living cells in a matter of seconds, UVGI is an ideal alternative to chemical disinfection. The use of chemicals is detrimental to the environment, and in most cases, can lose effectiveness over time due to the ability of microorganisms to develop a resistance to them.

There is no known living cell with a resistance to ultraviolet light, it occurs naturally within the environment, and does not affect the taste or smell of the UVGI treated substance.
