Ultraviolet (UV) rays belong to the band of the electromagnetic spectrum with wavelengths ranging from 10nm to 400nm. The UV water purifier is responsible for acting on the water and disinfecting it. If you are wondering how UV water purifier achieves this, here is the understanding.
The wavelength emanated by UV rays interferes with the normal DNA of microorganisms which is usually responsible for causing water-related diseases in the human body. Once it damages the DNA or gene of these organisms, it is no more capable of infecting the human body, and thereby no disease at all. The UV water purifier has become one popular choice for people who want to avoid any waterborne diseases. Almost all purifiers these days come with UV disinfectant.
How does a UV water purifier work?
Without any chemical treatment on water, UV rays can kill 99.9 per cent of the microorganism. UV chambers contain UV lamps. This is one of the stages of purification levels in modern water purifiers. Additionally, these lamps emanate UV rays, killing living organisms like bacteria, viruses, and germs in the water. However, before the water enters this stage, there is prefiltration too. Here, all the particulate matters where bacteria or germs could hide into are removed initially.
The UV lamps are encased in quartz sleeves to protect them from direct contact with water and are transparent to UV rays. Besides, this helps germicidal wavelength to reach the living microorganism. However, one thing to remember here is that it does not change the taste of water. It only removes harmful bacteria and viruses. Finally, when we come to usage, they are generally installed in households. Besides, they are kept in industries, wastewater treatment, offices, etc.
