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. The results can also be affected by the presence of some particles that can protect 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 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. You will find other firms say that they are offering 99% effectiveness. A cell can use UV light to repair damaged DNA. 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. If the bulbs have some dust coating it will lower the effectiveness. The bulbs will, therefore, have to be cleaned to make sure that the results do not interfere with so much.
The other thing that will have to be done is to make sure the bulbs will be changed. The design of the germicidal bulbs determine how long they will live. 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. If you are to get more accurate results, you need to ensure the lamps are shielded from the direct airflow. If you want to increase the performance of the UV, you can use reflection. One of the most efficient materials when it comes to reflection is aluminum. For you be able to measure the effectiveness of the UV in water disinfection, you need to compute the UV 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. 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 product that is made out of those conclusions may not be used for consumption depending on the deviation of the results or the effect of the interference experienced. That is why some processes have to have regulatory bodies to make sure everything is done in the right way.
