How Water Purifier Functioning?

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 particles that are traveling in your water.

A sediment filter can efficiently remove visible particles such as dirt, sand, dust, and debris. These are macro-particles that can easily catch because of their size of more than 0.6 μ. Sediment filters also remove turbidity & amount of chlorine from water.

This is the first and important level of water treatment systems. If the water contains any micro & macro containments, it can easily remove them.

How Water Purifier Functioning?

Pre-Activated Carbon Filter

It is the second level of the water filtration process. In this process, the water passes through an activated filter to remove chlorine and impure micro-organism such as pesticides. It is also ideal to removes bad taste and odor from water.

Ultra-Filtration Stage

Ultrafiltration (UF) is the third stage of water filtration. Under this process, the water passes through 0.01 μm tiny pores of the UF membrane to remove contaminating bacteria, viruses, algae, pollen, etc.

Reverse Osmosis Stage

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

In this phase, Water passes through from RO filter’s semi-permeable membrane by full water pressure.

This semi-permeable membrane made of synthetic plastic material which removes sodium, chlorine, calcium, and macro-organism/particles like bacteria, viruses, urea, glucose, etc.

Ultraviolet Purification

Ultraviolet Purification (UV) stage is the fifth and proven water filtration technology. In this process, there are UV light hits on harmful bacteria and viruses in the water. In other words, UV light kills microbes by exposing the water to the right light wavelength.

As a result, it destroyed bacteria, fungi, protozoa, and viruses from the water. At the end of the ultraviolet purification process, you will get fresh and pure water.

Post-Activated Carbon Filter

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

In the final analysis, the water passes through a Post-activated carbon filter & significant contaminants eliminate from the water.

In the last, it is supplying 100% pure water and also improved the water taste. Now the pure water is ready for drinking, cooking, showering, and other home uses.

T.D.S Controller

The TDS controller is the screw shape tool used to control the salts’ level and maintain the pH level of the purified water. As a result, It supplies tasty and healthy water for drink.


The function of the mineralizer supplies essential minerals that are lost during the RO purification process. The mineralizer is the best and most effective way to replenish the vital minerals compared to the TDS controller.

Reverse osmosis is a water purification process or technology that removes heavy contaminants from the water with water pressure through a semi-permeable membrane.

The water molecules go through a semi-permeable membrane in force of pressure uses by RO technology.

Under this RO water purification technology, Under RO water purification technology, it is surely removed each harmful contaminant from the water. The rest of the result will get crystal clear, tasty, and 100% pure water.

RO water purification process

RO is the only technology capable of removing harmful contaminants (lead, arsenic, mercury, fluoride, and chlorine) present in the water. These contaminants are most responsible for water hardness.

Therefore, with RO technology, you can filter any water source such as groundwater, seawater, tank water, etc.

The conventional RO water purifiers have a 25% water recovery. It means when you load 4-glasses of water. It filtered & supply 1-glass of water. Hence, The latest RO technology supplies you with 50% of purified water.

Besides, This R.O. water purifier’s latest technology is more capable of purifier water from heavy contaminants such as pesticides, fluorides, and some toxic fungi.

All water purifier brands extract wastewater. As per their guideline, you can use extracted water to wash the clothes, clean the utensil, and other routine works.

2. UV – Ultraviolet water purification technology

Ultraviolet purification is a powerful method to eliminate harmful microorganisms like bacteria and viruses from water.

First of all, this water purification technology is much better than other water purification technology.  It is because of emitting ultraviolet rays to kill harmful micro-organism. These UV rays produce from UV electric bulbs installed in the water purifier.

Moreover, UV purification is a more effective method to kill most complex components and toxic micro & macro-organisms.

This UV water purification technology requires consuming just 60 watts of electricity to perform well.

Process of UV purification

UV water purification process

Under the UV purification process, whenever water passes through from the UV filtration tube. Immediately UV electric bulb produces UV rays to break down harmful organisms’ genetic codes (DNA) and ultimately destroy them.

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

Purified water from UV technology is 100% pure, tasty, and naturally safe.

Everything has its advantages & disadvantage. Similarly, the UV purification technique has their burden that is unable to clean toxic components such as lead, fluoride, pesticides, and arsenic from water.

But don’t worry, Reverse osmosis (RO) technology can clean these toxic components.

3. UF – Ultra Filtration water purification technology

Ultra-filtration (UF) water purification technology can also remove harmful organisms & contaminants like bacteria, viruses, parasites, mud, and dirt present in the water.

For purification of these contaminants & organisms, there is no chemical or electricity required.

Ultra-filtration (UF) water purification technology is ideal for retaining minerals from the water. As a result, it saved extra costs during water filtration.

Similarly, the Ultrafiltration water purification technique cannot clean toxic components (lead, pesticides, fluoride, and arsenic) from water.

Process of UF purification

UF water purification process

The functioning of RO & UF technology is almost the same because both technologies using a membrane to eliminate toxic contaminants.

If you compare the functions between UF & RO, it’s pretty different. Let’s understand how?

UF water filtration technology uses the 0.02μm size of the fiber membrane whenever the water passes through by force from 0.02μm the size of the fiber membrane. 

This membrane extracts toxic components that were presented in the water. Hence, final result, you get pure & clean water.

What is TDS (Totally Dissolved Solids)?

TDS means total dissolved solids. It is nothing but some inorganic salt (calcium, magnesium, potassium, sodium, and chloride) and some other micro-organism in water.


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. Whenever the TDS level decreases, then the water becomes tasteless. In other words, strong possibility to see harmful contaminants.

So now the question is that, which TDS level of water is healthy for us? Let’s understand in the table 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 simple; you need a TDS Meter to measure the TDS level in the water. You can also select the best and affordable TDS meter from Amazon under Rs 500.

Checking the TDS in water

As you got a TDS meter, then On and dip into the water. Suppose it identified that your input water is 200 TDS level.

As per the table, this water TDS level is healthy to drink. Make sure neither the water TDS level over the 250 nor included harmful components.

Besides, you should have proper information about the guidelines for safe drinking water in India. To avoid this situation and ensure good health, we recommend using an RO water purifier in your home.

Quality of water in your location

Quality of water in your location

You must constantly 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 its TDS (total dissolved solids) is higher than 1000ml/liter.

If your locality water’s TDS level is higher than 500ml/liters, you should go for an RO water purifier. If the TDS level is less than 500ml/liters, then a UV water purifier is an excellent choice for you, rather than going for an RO water purifier.

At last, when water is highly polluted, and the TDS level of the water purifier is also higher, then go for RO+UV water purifier.

Different water sources – Best water purifiers in India

Different water sources

Life is not possible without water. All the living things in this world require water for evolution and reproduction. As you already know, 75 % of our body is made up of water. This is why water is the most important factor for living on earth.

There are mainly two types of water sources in the world such as surface water and groundwater. The surface water sources are rivers, lakes, reservoirs, ocean, and sea.

Second, groundwater is the primary source of many world populations and impure water source.

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

Each water source has many different impurities that require different types of water purification systems.

Causes of Water Pollution

Water pollution causes

Nowadays, water pollution is one of the worst challenges which getting increases day by day life.

Existence of water pollution

Water pollution comes into existence when harmful toxins materials come to contact with the river, lake, ocean, reservoirs, etc. End result, these water sources are contaminated with toxic substances & harmful micro-organism.

Besides, there are some water pollution sources like Industrial waste, domestic waste, and radioactive waste, and population growth, excessive use of pesticides, fertilizers, and leakage from water tanks. These are the 85% causes of water pollution.

Types of the storage tank

Make sure, the storage of fresh & pure water, it is important to check the quality of water tank material. Nowadays, most water purifier brands come equipped with ABC food Grade plastic, and their tank made with high stainless steel that ensures water purity and durability.

Water Recovery of water purifiers

Usually, all the RO water purifiers extract wastewater after purified water. The conventional RO water purifiers have a 25% pure water recovery. On the basis of the latest water purifier technology, there is 50% of pure water recovery.

Generally, each of the water purifiers extracted wastewater, but as per their guideline & recommendation. You can use extracted water for gardening, clothes washing, and home & kitchen cleaning.

Gedgetsworld always recommends selecting one of the best and equipped with the latest technology RO water purifiers in India.

Purification Capacity of water purifiers

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

The most significant 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 your purifier, then it will deliver 1-liter pure water. The rest of the water will become waste.

The wastage of water depends on the impurities and dissolved solids in your input water. The Higher the Dissolved solids and impurities your input water has, the higher it wastes the water.

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

There are various ways to use extracted wastewater after purification such as washing clothes, utensils cleaning, showering, gardening, car washing, and other use.

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

It is safe if you are using a secure 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.

6. What is a TDS controller?

TDS controller is a screw-based device that controls total dissolved solids in the RO purified water. Generally, the RO water purifier makes an almost 90% reduction of the harness of input water.

For example, let me explain: if the TDS level of the input water is around 1000, then the level of purified output water will be about 100 ranges.

Water with a significantly lower TDS level doesn’t taste great. To make the water healthy and consumable, it is essential to have some minerals and salt in the water.

The working process of the TDS controller is straightforward. When the water goes into the TDS controller presented in the RO water purifier system, 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 output water. This is the simple job of the TDS controller device.
