Article Synopsis
- Ultraviolet light-emitting diodes (UV-LEDs) are a promising alternative to traditional mercury lamps for disinfecting water by inactivating microorganisms.
- This study specifically examined the effectiveness of a bench-scale UVC-LED system at 280 nm on various pathogens, including E. coli, PhiX-174, MS2, and Cryptosporidium oocysts, under different water qualities.
- Results showed that while microbiological reductions varied with exposure time and water quality, UVC-LED technology was generally effective in achieving significant reductions of bacteria and viruses, highlighting its potential for use in small water systems as recommended by the World Health Organization.
