2.5 % of the water on earth is freshwater flowing through our rivers, waterfalls, streams and under the ground. Excluding the Glaciers, less than 1 percent of freshwater is available for drinking and use. And unfortunately, this minuscule percentage of freshwater is contaminated
making availability of drinking water scarce everywhere, including our country. And with growing water problems day by day, perfect water purifying technology is the need of the hour.
There are a lot of companies in the market which are implementing different technologies to bring out the best water purifiers to the customers.
So which one to choose?
Should we choose one according to the big brand name or should we judge according to the technology appropriate for us?
The answer is obvious. It's the water purification technology that should be taken care of while buying a new water purifier. Water from different sources has different TDS(Total Dissolved Liquid) levels. And different TDS level water requires different purification technology.
In further discussion, we are clearing all your doubts regarding the three most popular water purification technologies to break some age-old myths about the water purification process.
Join in the section till the end where we break down the best-suited technology satisfying water necessities of you and your family.
*But before going forward, it is necessary that you know the TDS level of the water available to you. You can easily do that by checking it with the help of a TDS meter or you can get it checked at a store selling water purifiers.
*There is a comparison table at the end for a quick review.
Let’s know about these three in detail:-
RO – Reverse Osmosis
Most of us have heard about this technology as most purifiers in the market are RO purifiers.
It is the most intensive technology of purification and is the best one to clear out the most contaminated water.
Working
RO purification technology works on the principle of osmosis in which the solvent molecules pass through a semipermeable membrane from a lower concentration solution to a higher one.
Here how this technology purifies water:-
Upside Aspects:-
As we know, with the help of RO water purification technology most contaminated water can be purified. This technology can remove impurities up to 90 %, including heavy metals, minerals, microorganisms and salts leaving demineralized, transparent, odorless and sweet tasting water behind.
And yes! This technology can even turn seawater into fresh drinking water.
In fact, RO technology was invented and developed for desalination of seawater at the University of California and the University of Florida during the 1950s. Since then, this RO technology is used in the water purifiers of ships and submarines to provide “Drinkable” water.
RO water purification technology is even used to treat wastewater after the ultrafiltration step. Hence, there is no doubt that this purification technology can provide the purest form of water.
Downside Aspects:-
A lot of water to throw away! Isn't it? And water is an abundance no more.
UV- Ultra Violet
UV water purification technology uses UltraViolet rays to kill bacteria and viruses present in water.
Working:-
There is no upside or downside of a UV based water purifier to be discussed elaborately. Just some points to be taken care of before use.
Important Aspects:-
UF- Ultrafiltration:-
This technology ensures safe drinking water for you and your family without adding chemicals or ripping off the minerals.
This technology has been used and preferred by some renowned research centres in our country and is extensively used in laboratories for its ability to retain the natural chemical properties of water.
Working:-
Upside aspects:-
Downside aspects:-
There is no downside to a UF filtration technology. Still, there are some points to be taken care of:-
After analyzing all the water purification technologies and knowing about them in detail, UF technology can be considered the safest one. It is quite effective.
UV combination purifiers should be chosen no matter what the TDS level is. This ensures safer drinking water which is bacteria and virus free.
COMPARISON TABLE:-
Cleaning ability:- | Ability to remove bacteria and clean dirty water. | Kills microbes of water. | Removes dirt, microbes and turbidity from water. |
---|---|---|---|
Requirement of electricity for working:- | Required | Required | Not required |
Working on TDS Levels:- | Above 900 | Works on any TDS level of water | Up to 900 |
---|---|---|---|
Maintaining the right amount of dissolved salts :- | Removes them | Keeps intact | Keeps intact |
Price of water filters:- | High | Moderate | Low |
---|---|---|---|
Maintenance of filters:- | High | High | Low |
CONCLUSION:-
Deep insights about these technologies specify that it is important to consider the TDS level of water before choosing a water purifier blindly.
Water is a commodity which when managed properly ensures perfect health and vigor.
So choose the right water purifier with the right technology wisely.
