How Does A Water Purifier Work? (Explained)

How Does A Water Purifier Work

Waterworks as oxygen for your organs.

In today’s world, where we are all surrounded by germs, harmful bacteria, and deadly viruses, do you even know how important it is to drink clean water?

Without having food, you can survive up to few weeks but without water hardly a few days.

Our human body comprises 60% of water, so making sure whether the water you’re consuming is free of harmful chemicals such as arsenic, barium, chloramine, chromium, and copper will help you improve your immune system.

Water full of gross smell or bad taste seems nasty to drink, so how do you convert it into clean drinking water?

Well, cheer up; you don’t need to worry. There are purifying water methods at the household level, such as boiling, distillation also now considered ancient techniques.

This is because these methods are time-consuming. Also, the taste of water changes, and we know it’s the last thing we want. Boiling and distillation also make us lose essential water minerals.

And so we end up relying on technology for the same. That’s when water purifiers come to us as our saviours.

There are water purifiers; they are not much time consuming also protects the nutrients and vitamins of the water.

Drinking clean water provides benefits to the body, such as carrying nutrients and providing oxygen to your cells, maintaining blood pressure, preventing skin disorders and moistures your skin, and improving your face’s elasticity, which will help reduce wrinkles and makes one look younger.

These days’ water purifiers have become an essential requirement in every household.

But doesn’t it make you curious to know how a water purifier works do?

C’mon, let’s check it out.

Firstly there are different types of water filtration processes happening inside the water purifier to convert the foul water into freshwater filled with nutrients that are needed for your body on a daily go-to basis.

And we are going to discuss them all.

 

Reverse Osmosis:

Reverse Osmosis

The first is the Reverse Osmosis system, highly known as the RO system in the water purifier.

It creates an outlet for water to separate the harmful molecules such as lead, ion through a semi-permeable membrane.

In such a way, the dissolving particles get separated from the drinking water.

RO method removes 90 to 99% of the contaminants from water. Therefore, it is a very effective method for filtering unwanted particles and impurities from water and making the water look crystal clear.

Also, it makes the water taste better, which improves the taste of your coffee and food.

 

Let us take a look at how it operates :

The Pre-filter Stage

Water from the tap passes through the Reverse Osmosis Pre-filter. Some widely used pre-filters are sediments and carbon filters. These filter helps to remove dust particles from the water and make it safe to drink.

 

The Reverse Osmosis Membrane

The RO membrane feature helps eliminate impurities from the water, making it the most essential unit of the water purifier.

 

The Storage Container

As the name implies, this tank is merely used for storing the purified water.

 

The Drainage pipeline

This tube is used to discharge the dirty water containing impurities, dust particles, and other filthy particles.

As there are two sides to a coin Reverse Osmosis (RO) method has two sides too.

 

Advantages

Provides high water quality :

The quality of water generated after the Reverse osmosis is outstanding, RO is the most effective method as certified by EPA   (Environmental Protection Agency )

 

Low in maintenance :

Due to the flexible design and since the process is performed automatically, it doesn’t require much maintenance.

 

Disadvantages

Essential minerals get parted:

While removing dissolved impurities, minerals such as iron, calcium, sodium also get detached in the process.

 

Time Consuming: 

RO purification takes a longer duration due to the additional filtration process, and mostly, it consumes two to four hours to complete the process.

This was all about RO membrane purification and its advantages and disadvantages that you should know.

Next, the UV disinfection is happening inside the water purifier to get rid of bacterias not visible to the naked eye.

 

Ultra Violet disinfection:

Ultra Violet disinfection

Your water may seem clean but is it really clean or infected with harmful chemicals which your naked eyes can’t see?

Water is exposed to Ultraviolet (UV) rays.

Here ultraviolet light rays attack bacteria, viruses, algae, and other microorganisms and destroy their DNA.

Hence destroying DNA helps them to prevent reproduction. If exposed to the correct dosage of UV rays, it’s difficult for any bacteria to survive.

Advantages

Free of chemicals :

No harmful chemicals are used in the process of filtration

Taste and Odour free:

To improve the quality of water, no odor or preservatives are added to improve the taste.

Extremely effective :

As UV rays are used, 99.99% of germs are killed, eventually making it safer to drink.

Low maintenance: 

Just changing a UV bulb is necessary; some water purifiers already have an indicator of UV light status.

 

Disadvantages

Needs Electricity :

The major disadvantage is the system doesn’t work when the electricity connection is lost.

No Storage Tank:

Setting up a storage tank is not possible, all the water must be stored in a separate container.

No Transparency :

Since UV light is always on, you need to guess whether the device is working or not.

The last one is the UF technique, which newly launched water purifiers have these days rather than old models. Let’s know what it is.

 

 Ultrafiltration (UF) Technique:

 Ultrafiltration (UF) Technique

Ultrafiltration is a type of water filtration technique where the fluid exerts pressure due to gravity, also known as hydrostatic pressure.

Gravity-activated carbon and sediment filters are used for the purification of water.

There’s a thin line of difference between Ultrafiltration (UF) techniques and the Reverse Osmosis (RO) technique.

UF is a classic technique for removing colloids, bacteria larger than the membrane pore size of water as compared to Reverse Osmosis.

Advantages

Most economical :

Just two basic filters, gravity, and natural water pressure are all you need to purify the water, resulting in low maintenance.

 

Eliminates the pollutants from the water :

The UF Filtration Process eliminates all the viruses, bacteria, microorganisms and then flushes them out from the system. It might also be noted that UF water purifying machines are better than UV.

UF filter provides a better result than boiling water. Also, it’s not much bulky so it’s easier to carry anywhere, anytime.

 

Extremely efficient:

The bacteria and viruses are killed in UV purifiers, but their bodies stay in the water, whereas the UF technique removes all the bacteria.

 

No need for electricity:

Only in this technique is there no need for electricity; it can be filtered using any standard pipe water pressure.

 

Disadvantages

Does not remove dissolved solids:

UF filters cannot remove solids that are already dissolved in water like nitrates and fluorides, mercury, etc., which can also cause harmful diseases like cancer.

 

How to know if you’re water purifier has stopped working?

How to know if you're water purifier has stopped working

Decrease in water pressure :

If the water force has dropped, there are chances that your filter is clogged with all the impurities and needs a replacement.

It is also possible that the filter would be broken internally, leading to the leakage of water. For this, you might need to call the plumber to examine the purifier and knowing the reasonable clause.

 

Keep an eye on the light :

Some water purifiers are provided with lights that get turned on when the filter has stopped working or when it needs replacement.

 

Odd Noise :

This is a common warning sign, and you need to examine the status of your purifier. Don’t ignore this red flag.

 

Bad taste in water :

Well, this is an evident sign that the purifier is in poor condition, and it will affect the taste and quality of your water.

 

Conclusion

So that’s a wrap. You have come a long way, and we hope you by now almost know in and out all about the working mechanism of a water purifier.

However, we want our readers to know that there are multiple options available in the market when it comes to buying top-rated water purifiers.

Make sure you consider the necessary factors while choosing a water purifier to make it the best choice.

Although you now already know how each part of a purifier works, we are definitely sure you won’t find it any big of a task.
