The effectiveness of the germicidal UV is determined by the time the body is exposed to the light. In addition to the length of time, the intensity and the wavelength also play a crucial part. Other things like the presence of particles can play a significant role in determining the right results. For you to obtain a near to correct results you have to circulate the water or the air several times through the UV light so that many microorganisms are exposed to the UV as much as possible. Many times sterilization is quoted as being achievable. in most cases it was difficult to achieve sterilization and that is why many companies use the word disinfection in order to avoid misusing words. There are other service providers that will say that that effectiveness is up to 99%. It is possible to repair damaged DN by the use of UV light. They do that through what is known as light and dark repair. In this case the effectiveness will depend on the line of sight exposure to the UV light. You can get different results if there is some dust covering the bulbs. That will mean that the bulbs have to be cleaned periodically if the results will be more accurate.
At times they will also have to be replaced if you are to get results that are close to the right thing. The lifespan of the germicidal bulbs depends on the design. They are also affected by the different materials used. With increased airflow the lamp is cooled, and when that continues it affects the output of the UV. Therefore it is necessary to shield the lamps from airflow so that the efficiency of the UV is not affected by the cooling of the lamp. Reflection is one of the ways that can be used to enhance the efficiency of the UV. One of the materials that can help you to achieve this effect is aluminum because it has a very high rate of reflection. If you want to evaluate the efficiency of the UV in water disinfection, you can calculate the dose.
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. When you use the wrong results, it means that the decisions that are made will have different effects because they are based on incorrect results. 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.
