What are the Advantages of UV disinfection?
Scientific researches in the field of sanitization have proven UV light’s ability to eliminate the extensive list of pathogenic organisms efficiently. It is advantageous over chemical disinfection processes such as chlorine-based disinfection process that is hazardous to human health. It is highly economical and can be easily installed. The UV light has no odour or taste and it doesn’t have pH conductivity as well, therefore, if it is used for the purification of water; it can neither react with water nor can eliminate its essential minerals. It is also very operator friendly. The UV disinfectant plant comes with immediate treatment processes with no requirement of holding tanks, long retention times, etc. It is easy to maintain and environmentally friendly with a low initial capital cost.
Effectiveness of UV in Covid-19: The current worldwide Coronavirus pandemic is of dire worry with its high transmission rate and fast spread all through the world. The novel coronavirus is strengthening its roots day by day upon the world and hand-sanitizers, disinfectants, etc., are becoming an integral part of our day to day life. In the attempt to fight against the COVID-19, which has crossed the bar of 2.5 million deaths worldwide, people are taking stringent precautions to keep themselves from catching the disease like disinfecting the commonly touched surfaces and quarantining themselves. The use of hand sanitizers and other disinfectants have been increased to many folds. Chlorine disinfectant is been widely used to disinfect roads and public places. The recent studies disclose that the novel coronavirus can survive on the metal or wood or paper surface for around 5 days which is appalling and makes the sanitization process to be taken earnestly and faultlessly. Since UV irradiation is been used to sanitize rooms and objects, disinfect water, etc. for quite a long time, therefore, it can be used in the sterilizing process in the war against COVID-19. Further, studies on the previous coronaviruses such as SARS and MERS suggest that they can be inactivated by UV radiation. Therefore, it’s not unreasonable to expect that it will have a similar effect on COVID-19. However, according to WHO human DNA can be damaged by UV radiation and can cause serious health problems like cancer or cataracts in the eye, therefore, exposing the human body to UVC light is not a good idea to eliminate COVID-19. According to a study, a particular range in the spectrum of ultraviolet light (Far-UVC) can effectively eliminate bacteria without causing harm to the mammalian skin.
Similar to India other countries such as the USA have also started adopting this technology for fighting against Covid-19.
We have started adapting various technologies to tackle the global pandemic situation. However, we don’t know the end of this pandemic situation. We don’t know how far we are going to walk with it. The only thing we are sure about is that we have to fight against this deadly disease. One sanitization method is never enough and when it comes to novel coronavirus that can survive on different surfaces for 4-5 days, the task becomes even tougher. UV disinfectant is an effective way to disinfect hospital rooms, malls, airports, etc. and is also an environmentally friendly method that is anyhow better than chemical sanitization.
