5 天之前 · In another study, a room was disinfected with a disinfection device that worked with 222 nm ultraviolet rays, and the people inside the room were disinfected. No eye-damaging effects were observed in humans working in a 222-nm UV disinfection room and obtained greater than 90% microbial inactivation (Kaidezu et al. 2023).

Ultraviolet (UV) irradiation is a proven and powerful means of disinfection. There has been a rising interest in the implementation of UV disinfection robots by various public institutions, such as hospitals, long-term care homes, airports, and shopping malls.

• UV disinfection is a physical process rather than a chemical disinfectant, which eliminates the need to generate, handle, transport, or store toxic/hazardous or corrosive chemicals. • There is no residual effect that can be harmful to humans or aquatic life. • …

• UV light does not penetrate wastewater solids. UV Guidelines dictate transmittance forming the basis of design. One year of transmittance monitoring can be used to increase design transmittance. A change from 55% to 65% decreases size of …

UVGI can be used to disinfect air, water, and surfaces, although surface disinfection is limited by microshadows and absorptive protective layers. Water disinfection is currently the most advanced and accepted germicidal application.

2023年6月20日 · UV systems are a globally accepted solution for water disinfection due to being a chemical-free sustainable solution, combined with being able of inactivating bacteria, viruses, and protozoa, which makes the technology vital for the future of water disinfection.

2014年1月1日 · Ultraviolet light in the UV-C band (200–280 nm) is also known as ultraviolet germicidal radiation and is widely used for sterilizing equipment and creating sterile environments, as well as in the food and the water industry to inactivate microorganisms.

2024年5月23日 · Germicidal ultraviolet-C (GUV) light, known for inactivating microorganisms by damaging their deoxyribonucleic acid or ribonucleic acid, offers a potential solution. This study examines the efficacy of GUV air disinfection systems in real-world outpatient environments.

Ultraviolet germicidal irradiation (UVGI) is a method of disinfection that uses the 254 nm radiation from low-pressure mercury vapor lamps to inactivate or kill microorganisms and pathogens on surfaces, in air, and in water. UVGI is commonly used as a germicidal UV-C light in the upper part of a room to inactivate airborne microorganisms.

2020年9月23日 · Still, it’s pretty damn impressive; UVC, which has the shortest wavelength and the highest energy of all the UV radiation, is a known disinfectant for air, water, and nonporous surfaces. So, when talking about UV light disinfection, the focus is on UVC, says Malley.

UV disinfection involves flowing water around a low-pressure mercury lamp, contained within a UV transparent sleeve, which emits bactericidal UV rays at 254nm. You might find these chapters and articles relevant to this topic. James T. Walker, ... Michael J. Weinbren, in Safe Water in Healthcare, 2023.

2021年3月12日 · Ultraviolet (UV) light is commonly used for disinfection. It inactivates microorganisms (including viruses) by degrading their genetic material and structural molecules so that they are no longer infectious.

2025年2月7日 · PX-UV disinfection was introduced as an additional terminal cleaning step in all patient rooms, regardless of the patient’s isolation status or infection history. The intervention involved routine PX-UV disinfection after manual cleaning protocols to assess its impact on reducing the incidence of HAIs. Despite the implementation of PX-UV ...

2021年11月16日 · The benefit of UV disinfection is the action on evolutionarily conserved targets (e.g., nucleotides). These non-specific targets are found in bacteria, viruses, fungi, and spores; making UV disinfection a promising strategy to prevent a variety of clinical pathogens.

As a water treatment technique, UV is known to be an effective disinfectant due to its strong germicidal (inactivating) ability; UV is energetic enough (ionizing radiation) that it can break chemical bonds, killing microbes.

2021年7月2日 · UVC disinfection technologies work by emitting an invisible UVC radiation (i.e. not part of the visible light spectrum) that disrupts a pathogen’s DNA and RNA so it cannot reproduce and grow.

2025年1月31日 · UV disinfection is an effective technol. for the inactivation of pathogens in water and is of growing interest for industrial application. A new UV source - UV light-emitting diode (UV-LED) - has emerged in the past decade with a no. of advantages compared to traditional UV mercury lamps. This promising alternative raises great interest in the ...

Abstract: Ultraviolet-C (UV-C) robot irradiation is a promising approach for disinfecting surfaces contaminated by pathogens in healthcare settings. However, limitations exist with current UV disinfection robots, including coverage for complex surface geometries. This research presents a system for human-guided robotic UV disinfection that uses empirical sensor measurements …
