- UV LED Water Sterilization: Applications in Purification and Disinfection Systems
As water becomes an ever more scarce resource, there is an increasing need to implement water treatment practices emphasizing sustainability, non-toxicity, and effectiveness. While chemical solutions like chlorine are implemented on a municipal level, UV treatment provides an additional layer of protection against microbial and biofilm buildup in the water supply and is an effective point-of-use disinfection method.
WAVELENGTHS: 280NM-265NM
UVC light rays can penetrate bacteria, viruses, molds, and other pathogens and inactivate nucleic acids that allow the germ to reproduce. This radiation renders the pathogens harmless, allowing safe water use without changing the taste, odor, or clarity of the water. As hardy bacteria like giardia and cryptosporidium cannot be effectively treated with chemicals like chlorine, UV radiation can be an efficient and powerful solution for water treatment
UVC LEDs are the Way to Disinfect Harmful Microbes in Water - Simple, Non-Toxic and Powerful
Compared with traditional lamps, the flexibility in wavelength tunability offered by UV LEDs offer a more targeted approach to disinfection, as peak wavelengths of inactivation vary depending on the pathogen type. While lamp systems can reach high flux at 254.7nm, UV LEDs at 280nm can reach similar inactivation with less electrical power consumption per reduction.
UV LEDs are also packaged in compact designs with lower power consumption, opening up innovative designs in point-of-use water disinfection technologies such as battery-powered water bottles or faucet-attaching modules. With greater flexibility in form factor and wavelengths, UV LEDs are well-positioned to provide non-toxic, revolutionary water treatment methods with the ongoing improvements in efficiency and integration of UV LED systems.
