UV LEDs for Surface Disinfection: Understanding Key Design Parameters and Development Workflow
By Pratibha Sharma, Ph.D., Saya Han and Peter Chung, Violumas Ultraviolet light is a known disinfectant, which reduces microbial load by denaturing pathogenic DNA. Wavelengths in the deep UV range, from 100 nm to 290 nm, with commercial devices available in the 200 nm to 280 nm range are the most suitable for microbial load reduction. While mercury lamps are commonly … [Read more...] about UV LEDs for Surface Disinfection: Understanding Key Design Parameters and Development Workflow
UV Water Disinfection – Multi-Power, Multi-Exposure, Multi-Wavelength
By Liz Stevens, writer, UV Solutions In water disinfection, as in so many other things, one size does not fit all. The differences in geographic location, site accessibility, available energy, local culture and economic condition among water users create unique demands for planning, installing and operating water disinfection technology. Technological options, UV type and … [Read more...] about UV Water Disinfection – Multi-Power, Multi-Exposure, Multi-Wavelength
What Will They Think of Next?
By Liz Stevens, writer, UV Solutions The power and utility of ultraviolet light is undisputed, and the technology can be found in places far and wide. Just when we are sure that every possible base has been covered, someone puts UV to use in another novel way. Fire and Water If there is one commodity that every fire department needs, it is water. In Wales, one fire and … [Read more...] about What Will They Think of Next?

Innovation: UV LEDs vs. Repair Pathways in Bacteria
By Liz Stevens, writer, UV Solutions When designing a UV treatment for the disinfection of water and wastewater against bacteria such as Escherichia coli, a bacterium’s recovery characteristics – its ability to self-repair – must be considered. Part of gauging the recovery potential includes assessing the water’s post-disinfection environment for self-repair-conducive … [Read more...] about Innovation: UV LEDs vs. Repair Pathways in Bacteria
