The abbreviation UV expands to ultra-violet light. In a UV system, UV light is used for the purification of water. It is used as a disinfectant to kill microorganisms present in the water. It uses unique lamps to emit light of a wavelength between 240 nm to 280 nm. These ultraviolet light rays are used to kill microorganisms such as viruses, bacteria, cysts, etc.
A UV water purifier kills the microbiologically unsafe water with UV light. Whenever the water is exposed to the rays, it disrupts the DNA of microorganisms. Due to this disruption, the living organisms cannot replicate themselves and make us sick if we drink that water. UV water purifiers are safe and effective.
Let us discuss the advantages and disadvantages of aUV water purifier:
1. It helps in the destruction of 99.99% of microorganisms.
2. It is eco-friendly because it does not leave any by-products after the treatment.
3. It is cost-effective and user-friendly since the only lamp and sleeve have to be replaced annually. Apart from it, hardly any maintenance is required by the UV water purifiers.
4. It is chemical-free, and there is no change in the taste and color of the water.
5. Water purification through UV rays is a quick process since the water flows through the system without a holding tank or reaction times.
1. It does not help in the removal of contaminants. UV deactivates only the living microorganisms. Therefore, a prefiltration of particles is necessary.
2. The UV lamps heat the water if the cleaner is not in use.
3. A UV system requires the power supply;y to run. Hence, an undisrupted power supply is necessary for the functioning of a UV water purifier.
How does a UV water purification system work?
1. In a water purification system, a stainless steel chamber is present. Inside which there is a glass quartz sleeve that holds the UV lamp is emitting ultraviolet rays.
2. The water is inserted through the water inlet, and it is directly exposed to UV light, where it attacks the genetic code of microorganisms and rearranges their DNA.
3. It eliminates the microorganisms’ ability to function and reproduce. Now, because a microorganism cannot copy and replicate, it cannot infect other organisms such as human beings when it comes in their contact.
4. After the water is freed from the microorganisms, it goes out through a water outlet, further processed and purified.
