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. If you want to obtain more accurate results, you have to pass the water or air several times through the UV in order to detect as many microorganisms by the UV light as possible. Sterilization is imagined in most cases as 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. You will find other firms say that they are offering 99% effectiveness. It is possible to repair damaged DN by the use of UV light. 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. The bulbs will, therefore, have to be cleaned to make sure that the results do not interfere with so much.
To ensure that the effectiveness is maintained, the bulbs will also have to be changed from time to time. The lifespan of the germicidal bulbs depends on the design. They are also determined by the different materials used. The airflow cools the lamp, and that contributes to lower the UV output. 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. 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. 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. The products thus produced may not be trusted because they are based on processes that are already interfered with. That is why some processes have to have regulatory bodies to make sure everything is done in the right way.
