Water Disinfection

USHIO develops specialised solutions for the disinfection of drinking water throughout the entire process chain. Along with UV lamps and ballasts which are used in large water purification plants, USHIO has developed a unique solution for the disinfection of drinking water at the point of use, e.g. in water dispensers and even water taps.

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.
