There is no life on this earth without water. In fact, life on Earth began in the ocean in the form of Fungi. That is why water plays an important role in the life of every living thing on this earth from the beginning of life until now.
So, drinking or consuming water that is not contaminated should be the first priority of every living being on this earth. There are so many benefits of drinking pure water but on the other hand, drinking contaminated water can cause many health problems. Hence Drinking a Pure Water is very beneficial for all living beings.
But have you ever wondered how this water is filtered? Mainly there are Three methods to filter water depending on the TDS level of that water,
- UV Water Filtration
- UF Water Filtration
- RO Water Filtration
and nowadays there are some filter which are using the combination of these filtration methods.
In this article, we will discuss everything you need to know about UV water purifier. With no wastewater, minimal maintenance, no use of chemicals to purify water and incredibly effectiveness, UV Purification method is regarded as one of the best methods to purify your water.

What is UV Water Purification System?
A UV Water Purification System is a disinfection process that uses germicidal ultraviolet light to kill any living organisms like bacteria or viruses that are very dangerous to us. If you drink that contaminated water then the harmful organisms like bacteria, viruses etc. Which are present in that water can embed in your digestive tract and replicate.
So, in UV water purification all bacteria, viruses, parasites and fungi are unable to reform themselves because the nucleic ids of their DNA are damaged by UV rays.
How does UV Water Purifier work?
As the name Indicates, a UV Water Purifier uses Germicidal Ultraviolet Wavelength to detect foreign particles such as viruses, bacteria, cysts to destroy their DNA so that they cannot replicate themselves. The UV light stops those living organisms present in the water from spreading diseases through drinking water.
The UV radiation kill those viruses, bacteria at the 254 NM wavelength.
When water enters in the system is exposed to the germicidal UV light without direct contact with UV lamp. A thin quartz glass sleeve acts as a transparent barrier in between water and lamp and it protects the water from making direct contact with UV lamp. The UV light from the lamp radiates through the sleeve. To ensure that water is unable to bypass, the lamp and sleeve are sealed by protective O-rings.
When the heat is exposed to the lamp, the mercury bulb present in the lamp starts emitting UV-C rays to kill the foreign particles present in the water. The life span of a UV lamp is approximately around 9000 hours. A sensor is fixed into the UV system so that you will get a warning when the life span of lamp is near to its end.
Are our UV water purifiers safe?
Yes, it is totally safe. It purify the water without using any kind of chemical. Instead it uses UV-C light to purify the water by killing living organisms present in the water. This UV-C light is also harmful to humans but you are safe as long as you do not touch the bulb.
Chlorine treatment is an alternative to UV Filtration, but there are some drawbacks of this treatment. UV treatment can remove all the living organisms from the water but the chlorine can not remove protozoa. it is much safer than Chlorine treatment.
|UV Treatment||Clorine Treatment|
|It can remove all the living organisms from the water||It can’t remove the Protozoa|
|Easier to maintain||Not much easier to maintain than a UV system|
|Only requires germicidal ultraviolet light||Requires retention tank and precise injections and solutions|
|No byproducts||Forms harmful byproducts|
Are UV purifiers effective?
UV water purifier kills about 99.99% living organism from the water. They can filter the water quickly. UV purifiers does not wastewater and keep in mind that every drop that enters the UV system is purified. UV water purification method is the most trusted purification method.
So everyone should get at least one of the best water purifiers in their home.
When to use UV Water Purifier?
If your water contains bacteria or pathogens then the UV Purification is the best option for you. In some rare cases like natural disasters, your water supply may be compromised then Having a UV system keeps your water free of harmful viruses and pathogen.
According to Indian standards, if the TDS level of your water is less than 200 then you should use UV Water Purifier to filter your water.
How to Maintain your UV Water purifier?
There is no doubt that a UV water purifier is a great way to rid your water of a variety of harmful organisms. It does its job perfectly, so regular maintenance is also required for it to work in the future with the same intensity.
However UV systems are easy to maintain and are designed to run continually.
Below are some ways to maintain your UV water purifier,
- Replace a UV lamp once a year- UV lamps use mercury as the source of energy to emit the UV rays. Over time this mercury gets disappear, hence you have to replace the UV lamp once a year. A UV lamp has a life span of about 9000 hours.
- Clean the quartz sleeve– When you change the UV lamp then also check for the quartz sleeve which surrounds the lamp to make sure it’s clean. It needs to be clean so the UV lamp will work efficiently.
- Replace the quartz sleeve once every two years– It’s good to change the quartz sleeve in every two years as they are fragile. This will generate a positive impact on the performance of UV water purifier.
- Be sure to purify your water before entering the UV purification system, as the UV system only kills pathogens in the water. It does not remove solid particles from the water.
