UV Purification
About UV Purification
UV light is used for many different things but you may be wondering how it can help clean water in your home? You have probably heard of the UV rays from the sun. These rays from the sun are really beneficial because they help your body create vitamin D but they also can be harmful and cause skin damage like sunburn. UV light is used in some other things such as tanning beds, inside the black lights at nightclubs, and also to sterilize medical equipment. We can say that one of the most beneficial uses of UV light to us is water purification.
UV Water treatment system consists of four main parts and those are the ultraviolet lamp, a high-quality quartz sleeve surrounding the lamp, a stainless steel chamber, and a system controller. The idea of a UV water treatment system is pretty simple but there is a lot of complex science behind the process of it.
Water will go through the steel chamber and there it's exposed to the UV light and it deactivates bacteria and pathogens. After that process is done then water is safe to consume. UV light achieves this by disabling viruses and bacteria. It attacks them and it also disrupts their DNA. When a microorganism's DNA is damaged then it can not function or reproduce and that means that it's not able to cause harm or infection.
In order to inactivate the DNA of the pathogens in the water, we need to use different intensities of UV light. Also, the flow of the water will have effects because that determines the time microorganisms are exposed to the light. So, UV light does not remove organisms from the water but it inactivates them.
If you only use UV radiation that will not have any impact on the smell, clarity, or taste of the water.
The percentage of the destroyed microorganisms will always depend on the intensity of the UV light and other things such as time underexposure, raw water quality. Proper maintenance is very important because it will also affect the percentage of the microorganisms that are being destroyed.
For example, if the particle load is high or the material builds up on the glass sleeve then the effectiveness of UV water treatment will be dramatically reduced. If sufficient dosage is used then all pathogens will be inactivated by UV radiation. When using low doses of UV radiation you may be concerned about the bacteria's ability to repair. That phenomenon is known as reactivation.
If you use water softeners and UV systems and let them work together then you will get the highest-quality water possible. Sometimes, to get the most of the UV filtration you will need a little bit of pre-filtration. UV light also doesn't remove dissolved solids and hardness in water.
UV system has to be clean all the time in order to reach the bacteria and inactivate them. They are capable of long and continuous operations but they should be shut down if you're not planning to use them for a few days. The lamp needs to be cleaned every day and also replaced once every year.
