UV treatment compares favourably with other water disinfection systems in terms of cost, labour and the need for technically trained personnel for operation. Water chlorination treats larger organisms and offers residual disinfection, but these systems are expensive because they need special operator training and a steady supply of a ...
The Catskill-Delaware Water Ultraviolet Disinfection Facility is a 160,000-square-foot (15,000 m 2) ultraviolet (UV) water disinfection plant built in Westchester County, New York to disinfect water for the New York City water supply system.

[12] This report also showed a significant reduction in other bacteria, fungal and viral bioaerosol , suggesting that portable filters such as this may be able to prevent not only nosocomial spread ...
UV-treated water must therefore not be exposed to visible light for any significant period of time after UV treatment, before consumption, to avoid ingesting reactivated and dangerous microbes. Recent developments in semiconductor technology allows for the development of UV-C Light Emitting Diodes (LEDs). UV-C LED systems address disadvantages ...
While you should take extra care when handling UV exposure of any sort, the UV light most effective at killing coronavirus, UVC, is also most effective at injuring living tissue. “That, in ...
COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.
