The effectiveness of the germicidal UV is determined by the time the body is exposed to the light. The wavelength and the intensity of the light are also other important determinants of the entire result. Another thing that can affect the effectiveness is if there are some particles the hinder the microorganisms from the UV light. in order to make sure the results are carefully correct, the air or water is repeatedly exposed to the UV light to make sure that a significant number of microorganisms are exposed to the light. Many are the times when sterilization is said to be workable processes. 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. Other companies will use the term 99% efficient. The damaged DNA of a cell can be corrected by the use of UV light. The process is referred to as light and dark repair. In this case the effectiveness will depend on the line of sight exposure to the UV light. With soil surrounding the bulb the effectiveness will be significantly affected. In order to increase the effectiveness, the bulbs have to be often cleaned.
To ensure that the effectiveness is maintained, the bulbs will also have to be changed from time to time. The design of the germicidal bulbs determine how long they will live. They also rely on the various materials that are used. When there is airflow it cools the lamp making the output of the UV to go down. 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. Some of the things that can increase the effectiveness are things like use of reflection. One of the most efficient materials when it comes to reflection is aluminum. If you want to evaluate the efficiency of the UV in water disinfection, you can calculate the dose.
If you have to get accurate results, care must be exercised to make sure there is no interference with the process otherwise that will alter the results entirely. 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 some processes have to have regulatory bodies to make sure everything is done in the right way.
