That will really help it out to make a purchasing decision better and smartly . 

Water purification technology

There are 3 types of water purification techniques such as RO (Reverse Osmosis), UV (Ultra-Violet), and UF (Ultra-filtration). Each of them is different from others and has some specialization and benefits. Below, I am sharing the in-depth details about each of the technology with their working process.

1. Reverse Osmosis – RO water purification technology

RO is a water purification process that removes harmful contaminants from water such as chemicals, bacteria, and viruses to make your drinking water pure and healthy.

The water molecules go through a semi-permeable membrane in force of pressure uses by  RO technology. Under this RO water purification technology, Each of the harmful contaminants is removed from the water. The rest of the water ensures clean, safe, and tasty.

RO water purification process

RO is the only technology capable of removing the hardness of water by killing harmful chemicals such as lead, arsenic, mercury, and chlorine presented in water. This unique technology is beneficial for purifying all types of water such as groundwater, seawater, tank water, etc.

The conventional RO water purifiers have 25% water recovery. That means by providing input 4 glasses of water it purifies 1 glass. But there are the newest models out there in the market that recover over 50% of input water.

As this RO water purifier technology is made to purifying high contaminants such as pesticides, lead, mercury, arsenic, chlorine, and fluoride from water. SO, as a result, it needs high electricity and wastes high water than any other water purifier.

But still, all the water purifier brands recommend using the wastewater in washing clothes, stencils showering, cleaning the home, and gardening purpose.   

Process of RO purification

RO water purification process
Sediment Filter

The sediment filter is the first level of the water filtration process which is not placed inside the RO water purifier machine. A sediment filter is like a net that catches the particulate matters that traveling in your water.

Sediment filter efficiently uses to remove visible particulate matter, and any particles of dirt, sand, dust, and debris that can be caught by its micron-rated capacity. Sediment filters also remove turbidity from water and reduce the amount of chlorine in the water.

The sediment filter is the first and important level of water treatment systems. If any kind of water contains any kind of containments such as viruses, bacteria, dirt, debris so usage of sediment filters is a necessary step to take.

Pre-Activated Carbon Filter

It is the second level of the water filtration process. In this process, the water is going through an activated filter to remove chlorine and organic impurities such as harmful pesticides presented in water. It is also ideal to removes bad taste and odor from water.

Ultra-Filtration Stage  

The ultrafiltration (UF) is the third stage of water filtration. Under this process, the water is passing through 0.01 μM tiny pores of the UF membrane to remove contaminating bacteria, viruses, algae, pollen, etc that hold all unwanted particles.

Reverse Osmosis Stage  

The Reverse Osmosis (RO) is the fourth and crucial stage of the water purification process. Under this process, the water is passing through UF Purified water to the RO membrane to remove all the TDS of water. 

In this situation, Water is passed in the semi-permeable membrane of the RO filter, under pressure.

The semi-permeable membrane is made up of synthetic plastic material that removes sodium, chlorine, and calcium as well as large molecules like bacteria and viruses, glucose, urea, etc..

Ultraviolet Purification  

Ultraviolet Purification (UV) stage is the fifth and proven water filtration technology.

In this process, UV light is used to kills harmful viruses and bacteria from water. In other words, UV light kills microbes by exposing the water to the right light wavelength. As a result, it destroys the DNA of bacteria, fungi, protozoans, viruses, bacteria, and cysts from the water. At the end of the ultraviolet purification process, you get fresh and pure water.

Post-activated carbon filter  

Post-activated carbon filter is the sixth and last stage of water filtration.

In the final analysis, the water is passing through a Post-activated carbon filter to eliminates major contaminants from your water.

It also ensures to supply clean, safe, and healthy water and improve the taste of your water.

The water is used for drinking, cooking, showering, and other home uses after this last purification process.

TDS Controller  

The TDS controller is the screw-based device that is used to controls the level of salts and balances the PH level of the purified water. As a result, it is used to supply tasty and healthy water for drinking.

Mineraliser

The mineralizer works are similar to the TDS controller. Usually, it is used to supply essential minerals that are lost during the RO purification process. As it replenishes the essential minerals then the mineralizer is the best and effective way as compared to the TDS controller.

2. UV – Ultraviolet water purification technology

Ultraviolet purification is a powerful method of cleaning harmful microorganisms like bacteria and viruses from water.

In this technology, all the viruses and bacteria presenting in the input water killed with the help of an Ultraviolet electric bulb that produces ultraviolet rays. Like any other water purification system, the UV water purification system also requires electricity to perform.  

But ultra-violet water purification system requires very little electricity to perform as it can run the same watt as a 60-watt bulb runs.

The great advantage of this UV technology is that it does use any harmful chemicals like chlorine or any other toxins.

Ultraviolet purification is a powerful and highly effective method of disinfecting bacteria and viruses from water.

Process of UV purification

UV water purification process

Under this UV purification process, firstly, the UV electric bulk produces powerful ultraviolet rays. When water passing through this UV purification technology, the UV rays exposes and Attack in all the germ’s genetic core (DNA) and perfectly destroy them.

The UV purification technology is ideal to kill 99.9% of destructive microorganisms without including any chemical or changing the water taste.

The process of Disinfection of the water with Ultraviolet light is extremely easy, powerful, and naturally safe.

But, The biggest disadvantage of this UV water purifier technology is that it is not sufficient to remove dissolved harmful substances like lead, pesticides, fluoride, and arsenic from water.

3. Ultra-filtration – UF water purification technology

UF water purification is a very beneficial technology capable of removing harmful viruses, bacteria, parasites, mud, and dirt present in water. All these contaminants are purifying even without electricity consumption and no chemical usage.

It is also ideal for retains minerals in the water. As a result, the technology doesn’t require much cost during water filtration.

 But the bad side of this water purification technology is that it is not sufficient to remove dissolved harmful substances like lead, pesticides, fluoride, and arsenic from water.

Process of UF purification

UF water purification process

The working process of RO and UF technology is the same. Because both are using a membrane to eliminate harmful contaminants from the water. But the UF water purification technology is still different from RO which I am going to explain below.

This UF water filter technology uses a fiber membrane that consists of 0.02 micron-sized very small holes. When the water passes under the UF water filter system, this system forces water in 0.02-micron membrane holes.

The water molecules that are large to this membrane such as harmful viruses, bacteria, parasites, mud, and dirt incapable to pass through these tiny holes. So they are clean from the water.

But the water molecules that are small to these holes such as pesticides, arsenic, lead, etc. are easily pass through these holes. 

What is TDS (Totally Dissolved Solids) presented in the water?

TDS means total dissolved solids. It is nothing but some inorganic salt such as calcium, magnesium, potassium, sodium, and chloride, and some small organic matter that dissolved in water.

TDS

Therefore, it comes from natural sources, sewage, urban development, industrial wastewater, and chemical used in farming processes.

The important thing is that your drinking water should have a perfect level of TDS, neither high nor low. Because when the level of TDS is low then the taste of water becomes horrible. On the other hand, the presence of contamination of harmful substances comes such as lead, arsenic, fluoride in water.

Now the question is that arises is, which TDS level of water is acceptable for human consumption. We will simply understand it by the chart below.

  

TDS Level MG/LTRResult
less than 150Fantastic
150-250Good for human consumption
250-300Not good for human consumption
300-500Unfit for drinking
Above 1200Unacceptable

 How to Check the TDS in water?

The answer is very simple; you need a TDS Meter that can check the amount of TDS in your drinking water. You can buy the best and affordable TDS meter from Amazon under 500. Besides that, you should have proper information about the guidelines for safe drinking water in India.

Checking the TDS in water

So now we have discussed the suitable TDS level for drinking water and also tell about the device by which you can check it. But still, if you check it and find that your input water has 200 ml/ltr that describes well for human consumption in the above chart. But still, it is not suitable for drinking because the water may have high amounts of arsenic, lead, fluoride, or mercury that is not extremely dangerous for your health.   

So to avoid this situation and ensuring good health, it is advisable to Use an RO water purifier in your home that can easily kill all the harmful toxins in your water.

Quality of water in your location

Quality of water in your location

You must always aware of this question that what is the quality of water in my location?

There are mainly two sources of water: surface water and groundwater.

Surface (soft) Water is the water that comes from lakes, rivers, and reservoirs. Groundwater (hard water) is the water that comes from under the surface of the earth.

 Groundwater is harder than surface water because it TDS (total dissolved solids) is higher than 1000ml/ liter.

 If the TDS level of your water is higher than 500ml/ liters then you should go for an RO water purifier. And if the TDS level of your water is lesser than 500ml/ liters then a UV water purifier is a great choice for you, rather than going for an RO water purifier.

 In the situation when water is extremely polluted and the TDS level of water purifier is also higher then go for RO+UV water purifier.

Different water sources

Different water sources

Life is not possible without water. All the living things in this world require water for growth and reproduction. Almost 75 % of the Human body is made up of water. This is why water is the most important factor for living on earth.

Mainly two types of water sources in the world are surface water and groundwater.

Surface water includes water that comes from the river, lakes, reservoirs, ocean, and sea is known as surface water.

Groundwater includes water that comes from under the ground is known as groundwater. Groundwater is the main source of many populations of the world and also a very impure source of water as well.

It is important to know that 97% of the water in the world is salt water that is not suitable for consumption. Only the rest of the water means 3 % of the water in the world is pure and freshwater means suitable for human consumption.

 The common sources of water in India are Municipal Corporation water, Borewell or Groundwater, river, lakes, or pound.

Here each and every source of water has many different impurities that require different types of water purification systems.

Water pollution causes

Water pollution causes

In today’s world, Water pollution is one of the most challenging problems that increase day by day. 

Many intellectuals even say that drinking water is the main cause of the Third World War.

Existence of water pollution

The pollution of water comes into existence when harmful toxins materials come into contact with the river, lake, ocean, reservoirs, etc. As a result, all these water sources are contaminated with toxic substances.

Industrialization, discharge of domestic waste, radioactive waste, population growth, excessive use of pesticides, fertilizers, and leakage from water tanks are major sources of water pollution.

 Need of water purifier

Need of water purifie

This is actually a foolish question to ask. Safe drinking water is a basic need for all humans.

About 71% of Earth’s surface is a cover-up by water. In which 97% of water is salt or wastewater which is not suitable for consumption and only 3% of water is only safe for drinking.

As a high volume of wastewater in the earth, according to the WHO reports 80% of diseases such as cholera, diarrhea, typhoid, and viral hepatitis, etc, are waterborne.

According to India’s planning commission, each year Between 4 to 5 lakhs children under the age of five years die in India from diarrhea.

Now in India, 30% of urban and 90% of the rural population still completely depends on the Unhealthy surface and groundwater. 

Types of the storage tank

It is important to see the material of the water purifier to ensure the storage of fresh and purified water.

Nowadays all the water best purifier brands come equipped with ABC food Grade plastic or high stainless steel tank that ensures purity and durability of water.

Here you need to make sure that the storage tank is properly airtight sealed to avoid any of the external contaminants.

Water Recovery of water purifiers

Usually, all the RO water purifiers wastewater during the purification process.

 The conventional RO water purifiers have 25% water recovery. That means by providing input 4 glasses of water it purifies 1 glass. But there are the newest models out there in the market that recover over 50% of input water.

If you want to buy an RO water purifier then go for a brand that has a higher water recovery ratio.

So due to the heavy water problem in the world and by seeing the above reports, it is requested that not to buy a water RO water purifier. In case if the TDS (total dissolved water) level of your water is less than 500PPM and the water doesn’t have any contaminants such as harmful chemicals, heavy metals, lead arsenic.

Rather than you can use some of the best Non-RO water purifiers such as gravity-based, UV, or UV+UF water purifiers, as they do not waste any water during the water purification process.

But still many water purification brands recommend using the wastewater to wash clothes, utensils, showering, any gardening purpose, etc.

Purification Capacity of water purifiers

The majority of the RO water purifiers include a water filtration limit somewhere in the range of 12-15 liters per hour. However, some top models offer a purification capacity of up to 20 liters per hour or considerably higher.

But before taking any decision or choosing any of the brands, always keep in mind members of your family and their drinking water requirements.

If you want to check yourself the after sell service for any brands of water purifier. So the effective way is to through an e-commerce website and reads the reviews of the customers who share their experience about after sell service.

3. How much water is wastage in RO water purification technology?

The biggest negative point of the RO water purifier is it wastes too much water during purification.

We can understand the water wastage in the RO water purification process with an Example: – If you put 4-liter water in it then it will purify 1 liter and the rest of the water will become waste.

But it is advisable by a company that you can use wastewater for washing clothes and utensils, showering, gardening purpose, etc.
But the wastage of water highly depends upon the level of impurities and dissolved solids in your input water. The Higher the Dissolved solids and impurities does your input water has, the higher it wastes the water.

4. How do I use rejected water by water purifier?

The water that is rejected by water purifiers contains a high level of impurities and dissolved solid that is not suitable for human consumption. However, there are various ways by which you can use it such as washing clothes and utensils, showering, gardening purpose, car, or any cleaning home any of your Vehicles.

5. Buying a water purifier online is safe in India?

It is safe if you are using a safe and trustworthy website like Amazon for purchasing it. But Before taking any decision check out the specifications of the product and price detail on the other trusty website a well.

6. What is a TDS controller?

TDS controller is a screw-based device that controls the level of total dissolved solids in the RO purified water.

Generally, the RO water purifier makes almost 90% reduction of the harness of input water.

Let me Explain, For example: – if the TDS level of the input water is around 1000 then the level of purified output water will be around 100 ranges. Water with a very lower TDS level doesn’t taste great. So to make the water healthy and consumable it is important to have some minerals and salt in the water.

The working process of the TDS controller is exceptionally simple. When the water goes into the TDS controller presented in the RO water purifier system then the TDS controller divides the water into two ways. The first way goes through the RO membrane.

On the other hand, the second part of the water goes into the UV and UF filters. But the UV and UF filters do not make any change in the TDS levels. This is why the two different outputs come.
At last, these two types of water mixed up and become as output water. This is the simple job of the TDS controller device.
