The Ultimate Guide of UV Water Purifier – (Pros & Cons)

Spread the love

Water was once clean, fresh, and drinkable. We pollute water, air, and food through our selfish actions.

Although we cannot control the air we breathe in, we can get clean water. Say thank you to water purifiers. The water we get from rivers, wells, and ponds is full of bacteria, viruses, cysts, inorganic elements, and dissolved salts.

Some examples of heavy Mercury, Lead, and Cadmium are all found in water. These heavy metals have five times more gravity than water.

Even tap water from the Municipal Corporation can contain a lot of bacteria and other harmful components. Pure water is essential and is the best medicine in the world.

All these impurities can however be eliminated by water purifiers. Reverse Osmosis Purifiers, UltraViolet water purifiers, and UltraFiltration purifiers are the most popular water purifiers in India. This post will discuss the Ultraviolet Water Purifier and its pros and cons.

In my previous post, I covered Reverse Osmosis Water purifiers and UF Ultrafiltration.

The Ultimate Guide of UV Water Purifier

What is a UV Water purifier?

The Ultraviolet Purifier (UV) uses UV Rays to kill Bacteria, Cysts, and other viruses in the water.

However, after killing them, Dead Bodies are still in the water. The majority of UV Water Purification Systems come with a Safety mechanism. This ensures that the power doesn’t leak when there isn’t water around the UV Bulb.

The UV Bulb kills all Bacteria and viruses present in the water when it flows around it. You can be sure to get safe and clean water.

These ultraviolet rays penetrate the cells of bacteria and viruses and kill them.

The UV Water Purifiers are simple yet effective in purifying water. UV Rays can kill 99.99% germs.

The Bulb, located in the Water Purifier, produces Ultra Violet Light that kills Bacteria. The Bulb is protected by a Quartz Glass Sleeve that blocks direct contact with water.

To operate the UV Water Purifier, you will need electricity. It uses approximately the same power as a 40 Watt Bulb.

If there is an outage, you can connect your UV Water purifier with a UPS or Inverter.


RO Water Purifier vs UV Water purifier

The UV Water Purifier uses Ultraviolet Rays, while the Reverse Osmosis purifier uses membranes to clean the water. Each uses a different method to purify the water.

The UV Purifier does not kill the Bacteria or cysts in water. However, their bodies are still present in water. Separate filters are needed to remove them.

RO Purifier removes all Bacteria and viruses from water.

The UV and UF purifiers cannot remove Dissolved salts in the water.

Water with a higher TDS level is not safe for drinking. Reverse Osmosis purifiers are capable of removing all Dissolved Salts from the Water. This is impossible with a UV purifier.

The RO Water Purifier comes with a TDS Controller and Mineralizer if you are unsure about the TDS levels in your water.


Ultraviolet water purifiers: The benefits

  • Without the need to add chemicals, ultraviolet radiation can kill up to 99.99% of harmful bacteria and viruses from water. To kill these microorganisms, disinfectants such as chlorine are used.
  • Water tastes the same regardless of whether chemicals such as chlorine are present.
  • The most effective method to kill microorganisms is ultraviolet water purification.
  • This water purification process requires very little energy to function. A UV water purifier consumes less power than a 60W bulb.
  • It is important to keep your UV water purifier in good condition. The UV bulb can be changed annually, and the water purifier will continue to work.
  • The environment is protected by UV water purifiers
  • One of the best things about UV water purifiers is their compatibility with other water purification processes, such as Ultrafiltration and Reverse Osmosis.
  • The UV water purifiers don’t waste water like RO water purifiers.

We’ve already discussed the benefits of UV water purifiers. These are the drawbacks of UV water purifiers that you should consider.


There are some drawbacks to using Ultraviolet water purifiers

  • Although UV water purifiers can remove bacterial and viral contamination they are not effective in removing heavy salt impurities such as chlorine and other metals, like antimony, arsenic, and lead.
  • UV water purifiers can’t eliminate volatile organic compounds. They cannot alter the taste of the water source.
  • UV water purifiers work with electricity. These water purifiers will not work if there is no electricity.
  • UV light has one major disadvantage: it cannot be turned off. The machine must be turned off completely. The UV light is also invisible. You might not be able to tell if the device is working properly. These water purifiers have UV fail alarms that indicate if the device is not working properly.
  • Ultraviolet water purifiers kill microorganisms, but they don’t remove their bodies. These machines need an extra filter layer in order to remove these contaminants.

The Final Verdict

The installation of ultraviolet water purifiers is usually very simple and inexpensive. It is very easy to change the UV bulb. You don’t need to hire a technician.

These water purifiers are now a common choice. There are many cities in India where the water source is soft, and it doesn’t contain any harsh chemicals or TDS. Only bacteria and viruses can build up in such water as they travel through pipes.

In areas with high levels of TDS or other impurities, UV water purifiers can be used as supplementary purification devices. They are effective in combination with other filtration methods such as RO water purifiers.

The UV Water Filter can be used if the TDS level in your water source is less than 400ppm.
