The effectiveness of the germicidal UV is determined by the time the body is exposed to the light. Other things like the wavelength and the intensity also play an essential part in getting the results. The results can also be affected by the presence of some particles that can protect the microorganisms from the UV light. If you want to obtain more accurate results, you have to pass the agua or air several times through the UV in order to detect as many microorganisms by the UV light as possible. Many are the times when sterilization is said to be workable processes. In reality it is not easy to say that you have reached sterilization results in any process and that is why you will realize many uses the word disinfection so that they do not appear to be lying about their results. There are other service providers that will say that that effectiveness is up to 99%. A cell can use UV light to repair damaged DNA. The process is referred to as light and dark repair. If you are to get the correct results you have to know the line of sight of exposure of the microorganisms to the UV light. If the bulbs have some dust coating it will lower the effectiveness. That will mean that the bulbs have to be cleaned periodically if the results will be more accurate.
To ensure that the effectiveness is maintained, the bulbs will also have to be changed from time to time. The lifetime of any germicidal bulbs depends on the design. They also rely on the various materials that are used. With increased airflow the lamp is cooled, and when that continues it affects the output of the UV. Therefore it means that it is important to shield the lamps flow airflow so that cooling does not take effect because if it does it will lower the effectiveness of the UV. If you want to increase the performance of the UV, you can use reflection. The results can be highly enhanced by the use of aluminum which is highly reflective. For you be able to measure the effectiveness of the UV in water disinfection, you need to compute the UV dose. Know about alimentos y envases here!
All these processes need a lot of care if you are to get the right results because a slight interference in the process will give completely different results. It is dangerous to get results that are far from the truth because that will mean the decision that are made are not correct and they will not have the intended effect. That will mean that the products made after the finds should not be trusted depending on how much are the results affected by the interference of the process. That is why regulatory bodies need to ensure everything goes in the right way. Get more facts about UV at https://en.wikipedia.org/wiki/Ultraviolet_index.
