Antimicrobial & Disinfection – The Technology:
UV light is electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. UV can be separated into various ranges, with short-wavelength UV (UVC) considered “germicidal UV”. Wavelengths between about 200 nm and 300 nm are strongly absorbed by nucleic acids. The absorbed energy can result in defects including pyrimidine dimers. These dimers can prevent replication or can prevent the expression of necessary proteins, resulting in the death or inactivation of the organism.
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.
UV-C light is weak at the Earth’s surface as the ozone layer of the atmosphere blocks it. UVG devices can produce strong enough UV-C light in circulating air or water systems to make them inhospitable environments to microorganisms such as bacteria, viruses, molds and other pathogens. UVGI can be coupled with a filtration system to sanitize air and water.
The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly it has been employed to sterilize drinking and wastewater, as the holding facilities are enclosed and can be circulated to ensure a higher exposure to the UV. In recent years UVGI has found renewed application in air purifiers.
How UVC Technology Works:
The incredible germ-killing power of UVC devices stems from the integration of ultraviolet germicidal light, or UVC light. Specialized light bulbs within our devices emit ultraviolet rays at a specific wavelength (254 nm) such that nucleic acids within dangerous organisms are disassembled and destroyed upon exposure, effectively obliterating dangerous microbes from the inside out by disrupting and scrambling their DNA! What’s more, this effect is universal: no microorganism on earth is resistant to UVC light!
Benefits of UVC Technology:
One of the most immediate benefits of UVC light sanitation is the fact that the method is entirely chemical free. Not only does this make the process inexpensive, it means little equipment maintenance is required, especially if a business invests in a simple sanitation station that can passively store and sanitize tools and hardware.
As far as environmental benefits, UV also delivers a collection of perks. Investing in UV light sanitation equipment can guarantee less money and gas is spent transporting cleaning supplies. After all, it doesn’t matter how green and environmentally conscious cleaning supplies are if they still have to be trucked from place to place.
In addition, there are applied product and service opportunities that will allow our firm to deliver this technology in a shared market capability. Our Carty Product delivery model will allow us to share this capability with Grocery and Department stores – like Walmart – with the ability to not only reduce germicidal risks for its Customers, but to accomplish this while actually earning revenues in the process.
