Henry Smith in Tech Bulletin describes major changes in office disinfection/cleaning including use of UVC wand for hard to reach places. Green Cleaning Green cleaning is a key innovation in office cleaning services as it improves the environment’s safety and benefits businesses and their employees. Businesses can drastically reduce chemical product usage and limit their carbon footprint by utilizing highly advanced green cleaning methods. Moreover, green cleaning reduces the inhalation of dangerous airborne pollutants commonly found in traditional cleaning agents, leading to some health concerns for employees and customers. Best Commercial Cleaning Company in Charlotte, NC, proudly introduces green cleaning…

Alfredo Gonzalez-Perez in Vatteninfo discussing the evaluation of using UV-LED for decentralized water treatment situations. Full PDF text available at: https://tinyurl.com/2enm4paw Water disinfection can be achieved with different techniques using chlorine,ozone, ultraviolet light or filtration. Among the different processes ultraviolethas become a technology of choice due to their proven efficiency inactivatingprotozoa, bacteria, and viruses. Ultraviolet light involves high process safety,ensuring that no harmful byproduct will be formed during the application. Themain germicidal UV sources are low-pressure mercury lamps, Excimerlamps, UV-LEDs, and other like medium-pressure mercury lamps and Xenonlamps that allow for pulsed operation (Bergman 2021). Those are used forwater,…

Inventors : Carter; Brian D. et al. Abstract A torchiere style sanitizing device for disinfecting airborne pathogens while providing aesthetic area lighting. A reversible fan exchanges air between the upper room air plume and the lower air plume by passing the air through a center disinfecting section. The disinfection section may include a linear UV-C light, reflective tube, and light trap positioned at one or both ends of the disinfection section to maximize the exposure of the air to the UV-C light and contain the UV-C light within the device. The device includes a conventional illumination source in an upper shade and can selectively provide one of more of room air flow,…

Kassandra Kania in Packaging Digest describes how Berkshire Sterile Manufacturing is using automated devices from five manufacturers including UV sterilizer from Claranor to produce sterile drug product packaging. Consistent growth coupled with a mission to provide the safest sterile drug products possible led contract manufacturer Berkshire Sterile Manufacturing (BSM) to invest in a fully automated, 100% isolator-based sterile fill/finish line with a freeze dryer. The fill/finish line, supplied primarily by Steriline, processes syringes, cartridges, and vials in bulk and ready-to-use (RTU) tubs for pharmaceutical and biotech companies focused on small-scale and clinical manufacturing. Prior to installing the new line, BSM’s facility had…

Mariana Vassal et. al. in Journal of Environmental Chemical Engineering reviews combining antimicrobial agents with Ultraviolet-C light for disinfecting surfaces and liquids. Full text PDF available at: https://tinyurl.com/2nc5jqyc Abstract Environmental changes and intense human activities enlarge the risks of infectious diseases and emphasize the growing importance of disinfection actions. Ultraviolet irradiation and chemical disinfectants such as hydrogen peroxide, peracetic acid, and chlorine-based compounds are the most commonly used for microbial control in different settings, namely water and food processing industries, hospitals, and other healthcare settings. But when applied individually, both ultraviolet radiation and chemical disinfectants present several limitations, which…

In an objection filed this week, Nitride Semiconductors Co., Ltd., urges the Honorable Glenn T. Suddaby to reject a 45-page report and recommendation Magistrate Judge David E. Peebles released late last month saying Crystal IS, Inc.’s, motion for summary judgment should be granted on one patent infringement claim asserted by Crystal and denied on a second. Because Crystal combines Aluminum and Gallium organometallics simultaneously, Magistrate Peebles explains, there’s never a time when just Gallium is singularly present in the manufacturing process as described in Nitride’s patent. Magistrate Peebles says the second claim Crystal wanted tossed will need to be examined at…
