Working Of UV Water Purifier

Ultraviolet water purification is the best kind of water purification system that uses the UV light to kill the various bacteria, germs, viruses, and other micro-organisms that are present in the water.

The UV light attacks the genetic core or DNA of the micro-organisms that are responsible for causing various water-borne diseases like flu, cholera, Hepatitis, Typhoid, etc. This destroys their ability to reproduce and multiply.

The UV light can only kill the disease-causing micro-organisms. They fail to remove dissolved solids and other impurities.

Thus, UV purifiers are often combined with RO, UF or sediment filters and activated carbon. The water is made to pass through the various stages of the advanced purification system. The final stage is when the UV lamp mounted in front of a chamber in which the water is made to pass.

Most of the UV water purifiers come with a UV lamp or a bulb, which is a significant part of the purifier. Usually, Ultraviolet Germicidal Irradiation (UVGI)  is used as a disinfectant method which uses short-wavelength Ultraviolet light (UV-C) to kill the various disease-causing pathogens and micro-organisms that live in the water.

The water is not allowed to have direct contact with the UV light because a high contact time would lead to too much exposure of the water leading to heat build-up and damage to the UV lamp.

On the other hand, a low flow rate or contact time would not allow the water to be exposed for an ample amount of time to be able to kill the germs and bacteria.

Thus, for this reason, the UV lamp is enclosed in a quartz glass sleeve or are mounted outside transparent tubes that transport water.

Advantages of UV Water Purifier

  • Chemical Free: UV water purifiers are chemical free and use food grade non-toxic materials that ensure that the taste and odor of the water are unaltered.
  • Safety: The ultra-violet lamp kills the micro-organisms that cause various water-borne diseases, ensuring the safety of our family.
  • Budget Friendly: The cost of UV water purifiers is very reasonable as compared to RO water purifiers making it a perfect option for those under a budget.
  • Ease Of use: It is effortless to use as you get purified water instantly by just switching on the electricity.
  • Low Maintenance: The cost of maintenance is less compared to other water purifiers as you have to change the UV lamp bulb annually.
  • Taste & Odor Free: UV water purifiers remove the taste and odor of chlorine or any other chemical, thus making it free from the weird taste.
  • Extremely Effective: The UV water purifier is safe, Requires low cost, it is easy to use and install, all in all, it is incredibly effective.
  • Requires very little energy: The watts used by UV purifier is very less, and it does not affect the electricity bills. Other than that, non-electric or gravity based UV purifiers are also available.

Limitations of UV Water Purifier

  • UV water purifiers can only be used in areas of low TDS (Total Dissolved Solids) as it is incapable of removing the dissolved solids, impurities, rust, pesticides, etc.
  • They require a constant supply of electricity to work. Hence, it cannot be used in areas where electricity problem exists.
  • They are unable to convert hard water into soft water.
  • UV water purifiers often have to be combined with another technology like RO or UF to filter out mud or any other impurities in the water, as it is incapable of giving complete pure water by itself.

How Do UV Light Remove Chlorine From Water?

We know that chlorine is used to kill germs and bacteria present in the water. However, excess chlorine that remains can be harmful as well as a hazard to human health. Not only that, but it also gives the water a bad taste and smell.

Ultraviolet light along with activated carbon can be a great combination to remove chlorine from water.

The UV lamp kills the various disease-causing germs, pathogens, and bacteria while the activated carbon filter removes the chlorine from the water along with any extra particles that contaminate it.

This combination removes the bad taste and odor from the water, and we are provided with clean, odorless, and safe drinking water. Thus, for those having excess chlorine in the water, especially in the municipal corporations, UV water purifiers along with activated carbon filter are the best option.

Types Of Water Purifiers

Here we compare the different kinds of water purifiers.

1. Electric Water Purifiers

As the name suggests, electric water purifiers work with the help of electricity. They are used mostly in areas which have continuous water and electricity supply.

These water purifiers remove Total Dissolved Solids (TDS), suspended impurities, contaminants and kill the micro-organisms present in the water, making it soft and suitable for drinking purposes.

  • RO Water Purifier

KENT Wonder 7-Litres RO Water Purifier

RO water purifier is a type of electric water purifier that uses the technology of Reverse Osmosis. This technology makes the water pass through a semi-permeable membrane that removes solid particles, impurities, and other contaminants. Thus, giving us clear and healthy drinking water. However, RO water purifiers are more expensive than all the other water purifiers.

Many water purifiers use the technology of both RO and UV to remove both dissolved solids and impurities along with killing micro-organisms present in the water. This also helps in converting hard water to soft water, providing safe, healthy, and germ-free drinking water for our families.

  • UV Water Purifier

UV water Purifier

UV water purifier uses ultraviolet radiation that helps in killing the various disease-causing micro-organisms.

However, these water purifiers are suitable for areas with low TDS as they are unable to remove solid particles from the water. They are less expensive as compared to RO water purifier.

2. Non-Electric Water Purifiers

Non-electric water purifiers work without electricity. They use gravity or water pressure to purify the water by removing dissolved chemicals, germs, viruses, suspended particles, and impurities.

Non-electric water purifiers are more suitable for areas with no continuous water and electricity supply. They are the best option for those under a budget.

  • UV Water Purifier

UF or Ultra-filtration water purifiers are non-electric water purifiers that use gravity instead of electricity to work.

They make the water pass through a semi-permeable UF membrane that traps the germs and viruses present in the water. They are also capable of removing mud and turbidity of the water.

This purifier is suitable for low TDS areas as they are incapable of removing dissolved solids.

UF water filter

Many water purifiers combine the technology of UV and UF. The UV lamp works by killing the various germs and viruses while the UF membrane filters out the bodies from the water.

  • Activated Carbon Water Purifier

Activated carbon purifier

Non-electric water filters that use activated carbon to remove inorganic contaminants and heavy metals from the water are called activated carbon water filter.

The carbon filter uses physical absorption to remove chemicals that give a bad taste and odor to the water.

They are much more efficient in removing chlorine and disease-causing pesticides, providing a safer and healthier form of drinking water that can be stored in the storage tank.

  • Sediment Filter

Sediment Filter

Sediment filters are cylindrically shaped filters that are sealed in a plastic container. This catches all the sediments present in the water like rust, sand, mud, and other unwanted impurities. These are present in RO and UV water purifiers as well as protecting them from getting damaged. However, it fails to remove germs, viruses, and heavy metals.

3. Gravity-Based Water Purifiers

One of the main advantages of this type of water purifier is that it does not use electricity to function.

Thus, gravity-based water purifiers are perfect for those areas in which power is scarce. The water gets filtered with the help of gravity where the water flows from the top to the bottom of the container without the help of any force.

Gravity Based water purifier

These water purifiers use micro fiber mesh, activated carbon or UF that absorb the impurities, dirt, and small carbon granules from the water. Thus, we obtain chemically free and safe drinking water.

  • Gravity-Based Candle Filter Purifier

Ceramic Candle Filters are made up of clay and have small pores on them. In these types of purifiers, the water is poured into the upper container and made to pass through the candle, which absorbs the various suspended particles, impurities and pathogens that are present in the water.

The filtered water is then collected in the lower container and stored for drinking purposes. Sometimes, colloidal silver is also used in the candle for a higher rate of pathogen removal.

Gravity based candle filter purifier

Candle filters are cheap and easy to use. They are useful in removing viruses, iron, and turbidity of the water along with improving the taste and smell of the water. However, they have a tiny purification rate.

Thus, sometimes more than two candles have to be used to purify the water. Moreover, the filtered water has to be boiled further to get purified and safe drinking water.

  • Gravity-Based Filters with Chemical Capsules

These types of filters are also referred to as Chemical Based Gravity filters.

Here, the water is made to pass through a micro fiber mesh that removes the suspended solid particles from the water.

Followed by this, a chemical such as chlorine is used to kill the bacteria and various disease-causing micro-organisms that are present in the water.

The excessive chlorine that remains is hazardous to human health, so the water is made to pass through the activated carbon filter for the removal of the chlorine.

Chemical Based Gravity Filters

Chemical-Based Gravity Filters are easy to use but have a high maintenance cost since the chemical batteries, and carbon filters have to be changed at regular intervals of time.

They are successful in the removal of virus, bacteria, suspended particles, and turbidity without the use of electricity.

Moreover, they do not require boiling, unlike the candle filter purifiers. They require regular cleaning and declogging of the filters.

UV Water Purifier Buyer’s Guide

Here, we provide a few points to keep in mind while purchasing UV water purifier for your home.

1. Test for Quality of Water

Water purifiers are designed to purify the different qualities of water. UV water purifiers can only kill the bacteria, germs, and viruses in the water.

However, they are unable to remove dissolved solids, mud, rust or any other suspended impurities. They cannot convert hard water into soft water. Thus, they are more suitable for areas which have soft water with low TDS levels.

It is important to understand the quality of the water that you get at your home. For this, it is essential to test the supply of water.

  • One way of understanding if the water is hard or soft is by the taste of the water. If you find the water is sour, then the water is Hard.
  • The second way is by taking some amount of detergent and lather it in the water. If the water does not wash properly, the water is hard.
  • Home TDS kits are also available. UV water purifiers are not suitable if the TDS level is more than 200 ppm.
  • You can also send a sample of your water to the labs for a quick analysis.

2. Installation

It is essential to purchasing the UV water purifier that can be fitted as per your convenience. Water purifiers can be wall mounted or can be placed on a table counter. Choose the one which goes with your preference.

On the other hand, installation can be a tough job to do on your own. Ensure that the UV water purifier comes with free and quick installation by the manufacturer.

3. How Much Is Drinking Water required by the family? ( Purification Capacity)

While purchasing UV water purifier for your home, it is important to understand the drinking water requirement as per the size of your family. Based on that, the UV water purifier should have sufficient purification capacity.

The purification capacity of the purifier you buy should be at least 60 L per hour so that you get enough supply of fresh, healthy, and safe drinking water for your family.

4. Storage

The UV water purifiers rarely come with storage capacity. Hence, before buying a UV water purifier ensure that you have a continuous supply of water.

This enables you always to get fresh and safe drinking water.

If you do not have a constant supply of water at your home, it would be better to choose a non-electric water purifier.

5. UV Fail Alarm

An important feature to look for while buying the ideal UV water purifier for your home is the UV fail alarm feature.

The UV light is invisible, so we are unable to know when the lamp stops working and fails to purify the water. The UV fail alarm notifies you when it is time to change the Filter. This is a convenient feature that ensures that you are always provided with pure and safe drinking water.

6. Mode of Operation

Ensure that the method of operation is easy. An automatic mode of operation ensures that the UV lamp automatically gets switched off when not in use. This enhances the overall life of the UV lamp, preventing you from having to spend a sum on purchasing it.

Moreover, The water purifier should be easy to use so that it can provide you purified water instantly with just the touch of a switch.

7. Electronic Monitoring System

Check if your water purifier comes with an Electronic Monitoring System. This ensures continuous scanning of the water during purification.

If there is any error during the stages of purification the machine will shut-off automatically. Thus, this feature assures pure or no drinking water.

8. Price

UV water purifiers are less expensive as compared to RO water purifiers. This makes it a suitable choice for those under a budget. Thus, you can easily choose a purifier which is available at a reasonable price.

9. Warranty and Service

Another factor to look for while buying a UV water purifier or any water purifier, in that case, is the warranty and after-sales service.

A minimum warranty of 1 year is always essential also ensure that you go for a brand that offers a great after sales service. This prevents you from having to spend a vast sum on the yearly maintenance.

10. Durability

Water purifiers are a necessity in every household. Thus, it is important to ensure that the UV water purifier you purchase is made of food grade plastic, which enhances the life and durability of the purifier.

The long-lasting water purifier saves you from having to spend your money in the purchase of another UV water purifier after just a short period.

11. Number Of Time You Need to Change Filters

UV water purifiers come with filters like activated carbon or sediment filters. While buying a purifier for your house, it is required to check the number of times you need to change the filters.

You need to change the filter at least once in 12 months or at an interval of 6 months. Most UV water purifiers also come with Filter change alerts that notify you when it is time to change the filter.

12. Speed of Filtering

The water flow of UV water purifier should be enough to meet your requirements. Ensure that the water purifier you buy filters the water fast. No one would want to wait long hours for the water to get filtered.

Thus, when you buy the UV water purifier for your home, ensure that it provides your family with safe drinking water instantly with just a press of a switch.

13. Wastage of Water While Filtering

Another critical factor to check for while making a purchase is that if the water purifier is leaking in any way while filtering.

A leaking water purifier means wastage of water. Hence, go for a UV purifier that is secure and filters the water without wasting any of it since, every drop of water counts!

Moreover, a leakage would lead to a messy kitchen.
