What Is RO UV UF MF & TDS In Water Purifier

If you are planning to buy a new water purifier for your home but still not sure with which technology you should go with, then you are not alone. Many people don’t know What Is RO UV UF MF & TDS In Water Purifier during the first time they buy a water purifier

With so many water purifiers available in the market choosing the best water purifier for home use can be quite a confusing task.

In order to select the best one for your home you should have a clear idea of what technologies are available in the market, how do they work, and which one is the right choice for you?

What does RO mean in a water purifier?

The full form of RO in a water purifier is Reverse Osmosis. It is the technique that is used in the purification of dirty water.

Features of a RO Water Purifier

• RO water purification system uses electricity for purification.
• RO technology can kill bacteria and Viruses from water.
• This technology removes dissolved salts and metals in water.
• Apart from filtering microorganisms such as bacteria and viruses the water purifiers also suspends visible impurities such as mud rust, dirt, sand, etc.
• The size of the filtration membrane is 0.0001 micron. Hence the passage of harmful materials is not allowed.
• RO water purification reduces almost 90% TDS in water.
• A few drawbacks include the wastage of a lot of water and the requirement of high water pressure. That is why an extra pump is used in all RO purifiers.

What does UV mean in a water purifier?

UV stands for Ultraviolet radiation. Yes, it is the same radiation that can be harmful if exposed directly to the human body. The Ozone layer of the earth protects us from these harmful UV rays of the sun.

Fortunately, these rays can be controlled and can be used to kill microorganisms- in this case purifying the water.

Features of UV water purification:

• UV water purification needs electricity for operation.
• UV rays kill bacteria and viruses, but their dead bodies remain inside the water. The water is completely safe to drink as the bodies of viruses and bacterias are either excreted out or digested by our bodies.
• UV rays do not do any filtration apart from killing harmful microorganisms.
• No membrane is used in UV water filtration.
• You cannot remove dissolved salts, metals, and harmful chemicals using this method.
• There’s a 0% TDS reduction
• No water wastage.

What is UF in a water purifier?

UF stands for Ultra-Filtration in a water purification system. This type of filtration method contains a hollow fiber threaded membrane for filtration.

Ultrafiltration is used to remove suspended solids or dispersed materials that are larger in weight and can be harmful to the human body.

Features of UF Water Filtration:

• Does not require any electricity to run.
• It can filter ou viruses and bacteria from the water.
• No need for high pressure is required for filtration.
• Filters suspended and visible impurities in water such as mud, rust, dirt, sand, etc.
• The size of the filter membrane is 0.01 micron.
• No water wastage is done.
• A few drawbacks include 0% TDS reduction, and cannot remove dissolved salts and harmful metals.

What is MF in water purification?

MF stands for Micro-Filtration in a water purification system. In this filtration technology, water is made to pass through a special small pore-sized membrane to filter out microorganisms.

Features of Microfiltration water purification are:

• Microfiltration does not require any electricity.
• It filters out only bacteria, not viruses.
• No extra pressure is required for water filtration.
• Filters out the suspended impurities such as mud, rust, dirt, etc.
• The membrane size is 0.1 micron.
• No wastage of water
• Some drawbacks include 0% TDS reduction and disability to remove harmful salts and metals from water.

So the question arises out of RO, UV, UF, and MF which is the most effective water purification technology?

As we have discussed above you would think that RO alone can remove all the impurities then what’s the need for other purification methods.

Well, you are wrong in a way. Complete water treatment requires pre-filtration, RO treatment, and other treatments such as mineralization, etc. 

The RO membrane can change the taste of water by making it bitter and unnatural. Carbon filters or mineralizer is used to enhance the taste.

Final Thought

It is advisable to use a mixture of water filtration techniques as every process has its own importance.

The best water purifier in India to buy should have a combination of RO, UV, UF, TDS Controller, and a mineralizer.
