Different Types of Water Purifier in India

Are you looking for different types of water purifiers? This list gives detailed information about the types of water purifiers in India.

Though two-thirds of our Earth is made of water and a third of the land, still there is a very limited quantity of water that is suitable for drinking. Most of the water is either found in seas and oceans and consists of high quantities of salt, which is unfit for human consumption. This leaves us with a very small quantity of water that can be consumed by humans. The consumable water, however, is being contaminated by various pollutants these days. It is therefore vital that water is purified first before drinking. In this article, we are going to have a close look at the different types of water purifiers in India and what points to remember while buying a water purifier.

Water contamination is a very common phenomenon in the present times due to the increased amount of environmental pollution. It is very harmful to human health, as water contains pollutants, which can be fatal.

Technology, however, seemed to have found a cure for this. Water purifiers play an integral part in our lives. Water purifiers are instruments that are designed to get rid of harmful pollutants and chemicals from water and make it suitable for drinking.

There are different types of water purifier based on various water purification methods.

There are different types of water purifiers that have several purification methods.

Types of water purification

Water can be purified through different types. Water purification is of the utmost importance when it comes to human health. The harmful contaminants in the water are capable of making humans contract several water-borne diseases which can finally lead to death. There are different methods of water purification. Before we talk about different types of water purifiers in India, let us have a closer look at different ways of water purification.

1. Membrane technology

Under membrane technology, we have

1.1 Reverse Osmosis(RO)

Reverse Osmosis is a very popular method of water purification that uses membrane technology. It is used to remove dissolved salts, impurities, and germs from the water.

The semipermeable membrane allows only water to pass through it and leaves behind harmful chemicals, dissolved salts, and microbes which remain suspended in water. Ro purification, however, alters the taste of water.

It is suitable for hard water that has a high TDS level. Thus, it is rightly known as a hard water purifier.

1.2 Ultra Filtration (UF)

Ultra Filtration purification method also uses membrane technology, but the difference is that it contains a membrane with more prominent pores. It removes all microscopic particles from water. It is, however, incapable of removing dissolved salts and solids.

The UF purification process is suitable for not very hard water and has a very low TDS.

1.3 Ultra Violet (UV)

Ultra Violet purification, being an e-boiling method, uses ultra-violet light to kill germs, bacteria, cysts, etc. it is capable of removing 99.99% of harmful organisms from the water. It uses a tiny mercury lamp that emits a short wave of UV radiation that purifies water and penetrates the cells of bacteria and viruses, thereby destroying their capability to reproduce, causing them to die eventually.

The dead bodies of the germs, however, remain in the water, which is further removed using a different process.

2. Carbon-based

Under the carbon-based method, we have

2.1 Activated Carbon

Activated carbon works by chemically bonding with the water and helps in the elimination of chlorine from water, thereby improving the taste and odor. It is, however, incapable of removing contaminants such as sodium, nitrates, microbes, and fluorides.

2.2 Carbon Block

These are block-shaped filters that are composed of crushed carbon particles. They have a greater effect due to their larger surface area. Their effectiveness depends on the rate at which water flows through these filters. Fibredyne carbon block has greater sediment holding capacity compared to other block carbon filters.

2.3 Granulated carbon

Granulated carbon works by using small grains of carbon to filter water. They are less effective compared to their block-shaped counterparts due to their small surface. In this process too, their effectiveness depends on the rate through which water flows through these filters.

3. Ion-based

Under the ion-based method, we have

3.1 Deionization

It facilitates ion exchange in the water to remove salts and other electrically charged ions. It removes contaminants that lack an electric charge. This method, however, does not remove viruses and bacteria.

3.2 Ion Exchange

This method uses resin to replace harmful ions with a less harmless one. This purification method is used for softening water because it can replace calcium and magnesium with sodium. This method, however, requires the resins to be charged with harmless replacement ions for the longevity of the filter.

3.3 Water Softeners

This method also uses ion exchange technology to reduce the calcium and magnesium levels of the water by replacing them with sodium.

So, these are different methods of purification of water.

Types of water purifier

Different water purifiers work using different purification methods. The different types of water purifiers in India are

1. UF (Ultra Filtration) Water Purifier

This is one of the different types of water purifier that uses hollow fibers of a membrane made of a thin layer of material to separate water from other particles present in water. This purifier can only block larger particles and hence is less effective than RO purifiers. These are therefore suitable for water with a low TDS level. Other than removing germs and bacteria, it is incapable of removing chemicals from water.

2. Activated Carbon Water Purifier

This is one of the different types of water purifier that work best for disease-causing pesticides and heavy metals. It removes chlorine from water. It is made of small pieces of carbon. Along with improving RO membrane life, it blocks chlorine and other particles that damage the membrane life. It improves the taste and smell of water.

3. RO(Reverse Osmosis) Water Purifier

The RO water purifiers remove metal particles like arsenic, fluoride, lead, chlorine, nitrates, and sulfates. It uses a semi-permeable membrane to purify water. The water pump in the RO water filter pressurizes the raw hard water to pass through the RO membrane that removes all the metal particles.

These water purifiers work best on hard water. These are one of the different types of water purifier that are preferred in parts of India, where the water has very high TDS levels. They are widely preferred in Indian households since they work on different sources of water like tap water, municipal water, bore well, etc. by improving the taste and odor of water.

The different types of RO water purifiers are wall-mounted or counter-top water purifiers and under-sink or under-counter water purifiers.

4. UV(Ultra Violet) Water Purifier

This is one of the different types of water purifier in which the water has to pass through a UV lamp fitted in the filter. When the water passes through the UV light, it kills all water-borne disease-causing micro-organisms, pathogens, and cysts making the water healthy and suitable for drinking.

However, the micro-organisms killed by the UV remain in the water, though it doesn’t cause any harm. They are suitable in regions where the water has a low TDS level. It keeps the taste of the water intact and has a high-efficiency rate as compared to RO, UF, and Activated Carbon Filters water purifiers.

Different Types of Water Purifier

These are mainly the four most important water purifier types. As we now know about the different types of water purifier, let us talk about some important differences.

Difference between RO and UV water purifiers

The difference between RO and UV water purifiers are –

RO water purifiers

They are best suited for hard water where the TDS levels are very high. They help in removing heavy metals, fluoride, arsenic, and other toxic impurities from water. It improves the taste and smell of water. They are capable of removing dissolved salts from water. It kills and filters the dead bodies of bacteria. They can work on muddy water. They require electricity to boost water pressure.

UV water purifiers

UV water purifiers use a UV lamp to remove contaminants from water. They are ideal for purifying tap water and municipal water. They work best on the water that has low TDS levels. It does not alter the taste and smell of water. They are incapable of removing dissolved salts from water. It is incapable of removing the dead bodies of bacteria from the water. They cannot work on muddy water. They can work with normal water pressure.

We have thus seen the facts about RO versus UV water purifiers. You are suggested to check the TDS level of water before investing in a water purifier.

Gravity based water purifier vs RO

Let us now see the difference between gravity-based water purifiers and RO.

Gravity based water purifiers

It uses a gravitational force as well as a filter to purify water. It can work without electricity or running water. The purifier works by removing dirt and pollutants as water flows from one section to another. It also has an activated carbon module that removes parasites, viruses, and other impurities, thereby making water safe and healthy for consumption. These can be used where the TDS level of water is low.

This also answers our questions to “what is a gravity-based water purifier?”

RO water purifiers

They are best for areas that have high TDS levels. RO water purifiers help in removing heavy metals, fluoride, arsenic, and other toxic impurities from water. It works on electricity. Ro water purifiers are one of the finest water purifiers which are available in the market.
