Harmful bacteria in drinking water has become a rising concern. Hiding in the nooks and crannies of building plumbing systems, water-borne bacteria (such as Legionella) multiply, becoming a public health hazard. In Europe, Legionnaires’ cases have been increasing quickly. By 2018, after a two year period the number of cases reported had increased by 60%.
The OASIS® QUASAR UVC-LED Water Treatment system uses UV-LEDs to protect people from Legionella and other harmful pathogens. Treating water at the point of dispense, QUASAR uses Light Emitting Diodes (LEDs) to generate high levels of UV photons. The rays are directed at viruses, bacteria, and other pathogens within drinking water to render those pathogens harmless in seconds.
OASIS’s Quasar is unique, as it is the industry’s only UVC-LED system that work directly at the point-of-dispense.
This means that there is no more remaining length of piping that can harbour bacteria or pathogens to infect the water. As an added bonus the UVC-LED disinfects the spout are [the exact dispense point]
UV represents wavelengths that fall between visible light and x-ray on the electromagnetic spectrum. UV photons penetrate harmful microscopic organisms and damage the DNA, rendering them incapable of reproduction. (microbiologically dead)
UV-LED technology is used to biologically destroy harmful bacteria and viruses, without the use of chemicals or mercury-based lamps. The UVC-LEDs allow for instant full- intensity power, unlimited cycling, remote start/stop, and no heat transfer to the water.
UVC-LED technology far outpaces traditional UV technology. Conventional UV lamps typically use between 5-200 mg of mercury per lamp, often requiring routine replacement due to the fragile quartz tube. UV LED lamps on the other hand are a much safer alternative as it is mercury-free.
Moreover, conventional UV while superior over chemical solutions, has a higher impact on the water temperature and causes fouling, thereby altering the taste of water. In contrast, LED technology is easier to maintain and use, with a longer lamp replacement interval.
