Inventor : Kaplan; Lawrence Abstract A breathing air compressor having an inlet air ultraviolet C light radiation emitter and viral and bacterial filtration system for air introduced into the air compressor. The viral and bacterial filtration system includes a cylindrical housing that includes a UVC radiation emitter mounted in a flow-through UVC radiation chamber, an inlet air particulate filter, and a flowmeter for measuring the volume and rate of flow of air to destroy viruses and bacteria present in any air flowing through the UVC chamber that is input air to an air compressor. The air compressor is typically used for generating breathing air for…

Fox 5 Atlanta reports on an additional study to one originally reported from the UK. This study was performed by University of California San Diego and University of Pittsburgh to test the impact on DNA of exposure to UV as in gel nail polish application. ATLANTA – Get a popular gel manicure, and you are going to spend some time under a UV-nail polish dryer to cure the gel and harden the polish. The lamps harden the gel, so that the polish lasts longer than traditional nail polish. But, a new study finds repeated exposure to the type of ultraviolet light…

Inventors : SINGHAL, Akshay Vivek Abstract (EN) The present invention provides a system and method for disinfecting all the surfaces of articles (101) transported on a conveyor system (102) in a disinfection chamber (100) through ultraviolet (UV) irradiation. The disinfection chamber comprises an external disinfectant module (104), an internal disinfectant module (107) and a mobile disinfectant module (108c). The external disinfectant module is a hollow cuboidal or curved structure designed to mechanically couple with one section of a conveyor system. The internal disinfectant module is designed to disinfect the lower surface of the article on the conveyor system. The mobile disinfectant module is designed…

Costa Group Holdings sustainability report for 2022 discloses use of recycled water in greenhouse tomato growing that embodies an ultraviolet filtration system. Full PDF version available at: https://tinyurl.com/2mduzqc9 Excerpt: Water Use and SecurityTomato glasshouse and nursery use 100% recycled water Costa’s expanded tomato glasshouse facility, on the New England Highway at Guyra (NSW), with an additional 10 hectares and a 2.5-hectare nursery, commenced production from January 2022. The entire site, which now totals 20 hectares of glasshouse and the nursery, uses a closed water capture system. This means that during years of average rainfall the site does not require…

Maria Zhivagui et. al. in Nature Communications discuss results of investigating DNA / cellular damage from repeated UV based nail polish curing and drying. Abstract Ultraviolet A light is commonly emitted by UV-nail polish dryers with recent reports suggesting that long-term use may increase the risk for developing skin cancer. However, the effect of radiation emitted by UV-nail polish dryers on the physiology and mutagenesis of mammalian cells remains unclear. Here, we show that irradiation by a UV-nail polish dryer causes high levels of reactive oxygen species, consistent with 8-oxo-7,8-dihydroguanine damage and mitochondrial dysfunction. Analysis of somatic mutations reveals…

The use of ultraviolet (UV) light for disinfection in healthcare facilities has gained significant traction in recent years. There is a growing consensus within the healthcare industry that UV light can be an effective tool for disinfection, particularly in high-risk areas such as operating rooms and isolation rooms. UV Disinfection: No Longer an Auxiliary Solution A proper sanitization method is vital for many reasons. Manjunath Anand from Clean Slate UV explains one of them: “And so the problem we are trying to solve or tackle here is that mobile devices are the third hands we never wash. The last…

Inventors : HONG PEIYING et. al. Abstract (EN) A wastewater treatment plant (100, 300) includes an anaerobic membrane bioreactor, AnMBR, unit (110) configured to receive wastewater (112) and to produce (1) a final permeate (114) and (2) a gas (116); an oxidation disinfection unit (140) configured to receive the final permeate (114) and to remove biological and chemical contaminants from the final permeate (114) to generate a final effluent (142); and an energy recovery unit (170) configured to receive the gas (116) from the AnMBR unit (110) and generate electrical energy. The wastewater treatment plant does not use chlorination. (FR) L’invention…

Carol Sanders in the Free Press reports on hearing in Manitoba, Canada regarding the environmental cleanliness of an Alberta silica sand project that would use ultraviolet light treatment of process water before returning it to the groundwater supply. The environmental hearing into an Alberta company’s silica sand project in Manitoba has been called the “poster child” for problems with the province’s vetting of such projects. “It’s really raising some fundamental issues about how we do environmental assessment and protect the environment,” said Public Interest Law Centre lawyer Byron Williams, who represents opponents of the project. He presented closing arguments…
