With all the new developments in the industry, it sure feels like GUV technologies and the related issues are evolving at Einstein’s cosmological constant, c – aka, the speed of light (pun intended). This makes it harder to keep up with cutting-edge developments and makes communication all the more critical. Once we start communicating, we need to collaborate, consolidate and … [Read more...] about Focus on Healthcare/UV Disinfection: Communicate, Collaborate, Consolidate and Educate: C3E

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
