1 maj 2016 · A new UV source — ultraviolet light-emitting diode (UV-LED) — has emerged in the past decade with a number of advantages compared to traditional UV mercury lamps. This promising alternative raises great interest in the research on application of UV-LEDs for water treatment.
Water treatment systems using UV LEDs should be validated in a similar manner to systems using mercury lamps, as fouling will decrease the UV flux of LED sources as well.
10 sie 2023 · LED technology has opened up new opportunities for water disinfection through its high efficiency, long lifespan, and flexibility in wavelength selection. Compared to traditional lamps, UV LED are smaller, have no warm-up time, and can be precisely controlled for optimal disinfection.
Introduced in 2012, PearlAqua is the world’s first UV-C LED product designed for water disinfection. This system integrates state-of-the-art LEDs into a unique and compact design, without the use of chemicals or mercury-based lamps.
Ultraviolet light-emitting diodes (UV-LEDs) have recently emerged as a viable technology for water disinfection. However, the performance of the technology in full-scale drinking-water treatment systems remains poorly characterised.
25 lip 2019 · Disinfection by ultraviolet (UV) light via non-mercury light-emitting diodes (LEDs) may be a sustainable solution for drinking water disinfection in small systems.
6 paź 2023 · Meanwhile, the photoelectric conversion efficiency of UVC-LED should be improved for future applications in water treatment. Based on the UV/H2O2 treatment results on synthetic PPCPs wastewater solution, this study showed the effectiveness of UV/H2O2 to degrade micro organic contaminants.
