UV-LED technology: the future of safe and sustainable water disinfection
UV-LED technology is a modern method to safeguard drinking water by disinfecting water with UV-pho-tons generated in a light emitting diode (LED). The technology has received increasingly higher attention due to its capacity to generate UV-light without use of mercury with a number of additional benefits compared to traditional UV-lamps. UV-LED’s are fast, operated digitally, has a potential to become very cost- and energy efficient and can be operated in pulsed mode with no lag at all for UV-generation. The development is rapid and in this paper, the design opportunities and potentials are reviewed and prospects for future broad use of UV-LED for disinfection of tap water and wastewater are highlighted.
