Different Types Of Water Purifiers

There are five types of water purifiers in India, depending on the water purification method.

RO Water Purifier

RO water purifier is one of the famous choices among Indian users. RO means reverse osmosis process. In this water purifier, there is a semi-permeable membrane.

When water passes through it, the thin-film composite membrane traps large contaminants. After that, we get pure water to drink.

In the water purification process, the water lips all impurities like lead Mercury sediment and others behind it ensure water safety.

Pros:

• Completely safe & pure water
• High-capacity storage
• Suitable for water with high TDS
• It also can purify hard water.

 Cons:

• RO water purifier might alter the taste of the water.
• There is also a chance of water wastage.

Composition of RO Water Purifier

RO water purifier has a multilayer composition. Let’s look at the components of the said water purifier to understand its working process better.

• Sediment pre-filter

It is the first layer of the RO water purifier. In this pre sediment filter, the fine particles get removed from the input water. Only smooth water passes through the RO membrane in the next steps. So the life of the RO membrane gets improved.

• Activated Carbon Pre-filter

If there are any harmful pesticides dissolved in the input water, Activated carbon filters out those pesticides to serve clear water. The activated carbon pre-filter is also very useful to remove awful order from our drinking water. It also helps to make the water taste better.

• RO membranes

RO membrane is the most exciting part of this RO water purifier. It is a semi-permeable membrane that removes hardness, heavy metals, contaminants, etc. This membrane has the power to eliminate micro bacterial impurities like a virus, bacteria.

This membrane is the reason that users trust in RO water purifier.

• TDS controller

The importance of TDS controllers in a water purifier is to maintain essential minerals in the output water. The Reverse Osmosis process sometimes removes minerals from the water, like calcium and magnesium. But with a TDS controller, the balance of essential minerals gets verified. 

• UV filter

The next stage of the RO water purification process is the UV filter. There is a high-intensity UV bulb placed in the water purifier. The UV rays from this bulb securely kill the virus, bacteria, and different parasites living in the water. UV filters are one reason that RO water purifiers purify water up to 99.9%.

• Carbon post-filter

In the Reverse Osmosis process, the taste of the water can get altered sometimes. The carbon post-filter helps to maintain the original taste of the water. Your drinking water gets healthy and tastier with r o water purifier.

• Storage tank

RO water purifier has a storage tank to store purified water. Having a storage tank in your water purifier can reduce your work pressure. You can do some other household chores while your drinking water is getting purified.

• Smart display

Most of the RO water purifiers have smart building technology to make it more convenient for busy people. There are simple displays with emergency alerts. You can easily change the RO membrane or check the TDS level in the indicator.

Ultrafiltration Water Purifier

When groundwater has less chemical contamination trapped in it, the UF water purifier is crucial for those regions. The simple technology used in this water purifier makes it cost-efficient for every consumer base. People can have safe water with little investment in it.

The purification process of ultrafiltration water purifier is very much similar to RO water purifier. In UF water purifiers, there is also a thin layer of fiber membrane. It helps to separate impurities from the input water.

The best part about the Ultrafiltration water purifier is it does not need electricity to perform. All you need is to pour water into the water purifier. And it will get purified by passing through double layers of filters. Whenever it passes through filtering sections, it leaves contaminants, germs behind.

The only difference between a RO water purifier and a UF water purifier is that RO removes microorganisms from water more efficiently. The pores of a UF water purifier membrane are larger than a RO membrane. So a UF water purifier cannot remove microparticles.

Pros:

• It is a cost-effective solution for having safe water.
• UF water purifiers also can clear out muddy water.
• A smart portable building is another turning point of this water purifier.
• The excellent purification process is another vital point of this product.
• It works well in low water pressure.

Cons:

• UF water purifiers cannot separate dissolved salts from water. So it cannot remove the hardness of the water.
• It is a high maintenance product. The product needs cleaning frequently.

Components of a UF water filter

UF water purifiers generally have two different purification filters. Here I have noted down the importance of those filters in a UF water purifier.

• Activated carbon filters

The activated carbon filter is the master filter of a UF water purifier. The carbon filter presents above the lower compartment of an ultrafiltration water purifier. As there are plus charged ions present in the activated carbon filter, it absorbs the chlorine-based contaminants.

To provide those positively charged ions, manufacturers use woods, coal particles, and coconut shells in the water purifier. Activated carbon also works great to remove foul odors from the water.

It also keeps the balance of the original taste of the input water after it passes through this filtration stage.

• Sediment Filters

There is another filtering section above the activated carbon filters. The sediment filtering section helps remove dust particles from the input water. If large impurities are lying in the water, sediment filters help to get rid of them.

The pores of the sediment filters are suitable only for large molecules. The difference between both filtering sections shows how brilliant the UV water purifier building is. Both filters perform individually and get rid of every impurity from the water. We get to drink clean & safe water.

UV Water Purifier

An ultraviolet water purifier is undoubtedly one of the safest water purifiers available in the Indian market. This multi-layer water purification system ensures to eliminate 99.99% of germs and bacteria from input water, and we get safe and clean water to drink.

The best part about this water purifier is that there are no chemicals used in the purification system. So this purifier is also a product that serves the human race while protecting nature.

Pros:

• A UV water purifier is an eco-friendly choice.
• The water purifier does not alter the taste of the water under the purification process.
• It is also a low maintenance system in nature.
• UV water purifier consumes less power to operate.

Cons:

• It can not remove chlorine & arsenic from the input water.

Components of UV water purifier

Now, look at the components of a UV water purifier. You will see four units inside the water purifier. Let’s discuss a little more about these components and their working process.

• The Reactor chamber

There are stainless steel chambers for the reactor placed inside the water purifier. It houses the UV lamp and sleeve. The crucial importance of this chamber or reactor is to control the water flow inside the water purifier.

You can get various types of a chamber according to the unit of the water purifier. Building from original materials & in different shapes, a water chamber always performs equally well in controlling the water flow throughout the water purification system.

• The UV Lamp

The role of a UV lamp placed inside an ultraviolet water purifier is to produce UV-C rays. UV-C is a wavelength of UV light that is germicidal. The rays eliminate various kinds of germs, bacteria, and viruses living in the input water.

There are different UV lamps available in the market, and their disinfection process is also distinct depending on the application.

• The Quartz Sleeve

It is a cylindrical tube made of Quartz glass. The importance of a quartz sleeve in a UV water purifier is to protect the UV lamp in the water.

The UV lamp transmits UV-C wavelength throughout the tube into the water. Otherwise, minerals and other contaminants can hamper the sleeves. That is why the Quartz sleeve needs regular cleaning.

For the purification of water, the Quartz sleeves are a crucial component of a UV water purifier.

• The Controller Unit

The controller unit is the most crucial part of a UV water purifier. It is more like a brain to control the functions throughout the system. The control unit controls the electrical output inside the water purifier.

It also powers the UV lamp to produce UV C wavelength. The complexity of a controller unit can vary in different UV water purifiers.

There are some other optional components inside a UV water purifier. But these four are the most crucial parts of the system.

Activated Carbon Water Purifier

The activated carbon water purifier has gradually become a mainstream water purification system. If your home groundwater is high on free chlorine, then having an activated carbon water purifier is essential for a home.

Activated carbon is very efficient in removing heavy metals from water. That is the reason activated carbon water purifier is one user’ favorite. Charcoal is activated carbon.

People can usually derive activated carbon from coal, coconut shells, nutshells, and wood. Especially if the water carries many waterborne diseases caused by pesticides, activated carbon water purifiers are heavily compatible in purifying those kinds of water.

Pros:

• An activated carbon water purifier efficiently eliminates waterborne diseases caused by pesticides.
• Activated carbon water purifiers are also helpful to eliminate toxic contaminants like chlorine.
• Heavy metals also get eliminated.
• It does not alter the original taste of the water.
• There is no foul smell found in the output water.
• Activated carbon bed is also an essential component in other water purifiers, like RO water purifiers.

Cons:

• It cannot remove the hardness of the water.
• Activated carbon does not help remove dissolved salt.
• An activated carbon water purifier does not eliminate bacteria and viruses.

Work process of activated carbon filters

Activated carbon filters work on the method of physical adsorption. It happens when water passes through an activated carbon bed. Intermolecular forces break molecules into macromolecular pieces. Then traps them on the surface of activated carbon.

That is how contaminants get attracted to the activated carbon bed in the water purifier. Besides physical adsorption, there are also chemical reactions performed by activated carbon.  That also helps to purify water.

Free chlorine molecules can react to acids and form carcinogens. But chlorine comes into contact with activated carbon in this water purifier. Then it forms chloride ions and gets trapped in the carbon bed.

Types of activated carbon water purifier

There are mainly two types of carbon used for water filtration. One is powdered activated carbon, and one is granular activated carbon.

• Powdered activated carbon (PAC)

Powdered activated carbon is a smaller particle and efficiently traps various impurities from the input water.

• Granular activated carbon filter

Granular activated carbon filters have wide usage in the industrial water purification system. In this type of filter, there are cylindrical containers holding particles of granular activated carbon.

Water passes through the cylinder and flows into the system. The loose carbon particles filter out the impurities from the input water.

But the major disadvantage of a granular activated carbon filter is that it is high in maintenance. The carbon bed needs cleaning regularly. Otherwise, the trapped organic impurities can form bacteria or microorganisms in the system.

Passing the water through the container of granular activated carbon is also strenuous. Water often passes through the part where there is no or less resistance by the carbon bed. It can hamper the purification process.

• Carbon block filters

A carbon block filter is a combination of the powdered activated carbon filter and granular activated carbon particles. Water passes through the blocks of carbon, and the carbon particles remove the impurities.

Passing the water through the carbon block is easy. Also, the surface area is larger than other activated carbon filters. So a carbon block filter more effectively removes contaminants.

Sediment filter

Just like its name, a sediment filter removes different sediments. If there are any impurities like dust, sand, or any suspended solid, a sediment filter removes those.

Unlike other filters, sediment filters can eliminate impurities we can see in naked eyes like mud, silt, or any other solid particles. A sediment filter is a pre-filter.

You can connect a sediment filter with a RO or UV water purifier. Then the output water of a sediment filter automatically passes to the other water purifier as input water.

Pros:

• You can use a sediment filter for the whole house water supply.
• It catches debris by its micron-rated capacity.
• A sediment filter protects house appliances by separating solid particles from the water supply.
• You can use it with your RO or UV water purifier to have 100% safe water.
• It does not change the taste of the water.

Cons:

• It does not eliminate heavy metals, dissolved salts.
• A sediment filter is also not very efficient in removing germs & bacteria from water.
• It can’t remove any foul smell from water.

Why Sediment filter is important

Until now, the water purifier has only served pure drinking water for our good health. But sometimes, when groundwater is full of solid particles, it can hamper our household appliances.

When water pipes get rusted, the flakes can get mixed up in the water supply. It can clog geysers and other home appliances. Also, input water high in sediments can prevent efficient reverse osmosis and ultraviolet purification processes.

In times like this, a sediment filter can make your life easy. You can manage your home more comfortably with the sediment filter attached to your RO or UV water filter.

• How a sediment filter works

The work method of a sediment filter is mechanical filtration. Like we catch any unwanted bug in our home. A sediment filter catches unwanted solid particles in the input water. But a sediment filter does not prevent water from flowing.

It only separates solid particles in water. We even can cool water at that stage. When water passes through a sediment filter, the core of the filter becomes narrower. It lets only pass the water slowly. Thus it catches solid particles.

Now you know how to choose the best water purifier in India. Bring that to your home and enjoy safe drinking water. We wish you good health.
