Water purification technology

Currently, we have mainly three types of water purification technology available. These are RO (Reverse Osmosis), UV (Ultra-Violet) and UF (Ultra-filtration), respectively.

The working principles of these technologies are different, and each of them has its advantages and disadvantages. Below we will try to briefly give you an idea of ​​how each of these technologies works and their benefits.

1. RO (Reverse Osmosis) water purification

Presently, RO (Reverse Osmosis) is the most advanced and effective water purification technology. It can efficiently remove harmful contaminants such as chemicals, bacteria, and viruses from your drinking water.

It is particularly important to note that, among the currently available water purification technologies, RO is the only technology capable of removing harmful dissolved solids such as pesticides, arsenic, lead, mercury etc. from water.

2. UV (Ultraviolet) water purification

UV (Ultraviolet) purification is an effective method that kills germs present in the water by ultraviolet radiation. In this case, an ultraviolet bulb is used that produces ultraviolet rays. And when passing through this ray, almost all the bacteria and viruses present in the water die.

Like the RO purification system, UV water filters also require electricity to function. It should be noted here that the process is entirely chemical-free.

3. UF (Ultra-filtration) water purification

UF (ultra-filtration) technology is an effective water purification method that can remove harmful microorganisms from water. It is also capable of purifying mud and dirty water.

The advantage of this method is that it does not require electricity to work. And no chemicals are used in this case. In this method, water can be purified at a very low cost. That is why it is a widely used method of water purification.

But even with so many benefits, this technology has a significant disadvantage. This method cannot remove dissolved harmful substances like pesticides, lead, fluoride and arsenic from water.


Best Water Purifiers in India – Buying guide and tips

You can’t survive without water. You must have access to pure drinking water to stay healthy. Now, in India, water pollution is alarming. Hence, a water purifier is necessary for every Indian household.

Right now, many water purifier brands and their numerous models are available in the Indian market. Everyone claims to be the best. Now the question is which one is right for you.

Do you buy new water purifier every year? Of course not. As a buyer, you would expect that after purchasing a water purifier, it will provide you with continuous service over the next several years.

1. Different sources of water

Life on earth began with water, and water nourishes life. Life without water is not possible. About 70% of the human body is made up of water. Also, water is present in all plants and animals. That is why water is considered as one of the most essential and valuable resources on earth. Water sources are mainly of two types, namely Surface Water and Groundwater.

What is Surface Water? In short, the water present above the ground is considered as Surface Water. That is, the water contained in the oceans, rivers, lakes, streams and reservoirs is called surface water. The primary source of Surface Water is rain and continuous melting snow in the mountains.

2. Causes of water pollution

Water is one of the world’s most valuable resources. We all know how vital water is to our lives. In future, the lack of pure drinking water could endanger our existence on earth. Unfortunately, even knowing this, we are polluting water every day.

Water pollution is one of the most severe problems in the world right now. And the problem is increasing day by day worldwide. Many intellectuals even say that the Third World War is about to happen because of drinking water.

Let us now briefly understand why water pollution occurs. Water pollution occurs when various harmful toxins enter and dissolve in water sources such as rivers, lakes, oceans, etc. As a result, all these water sources are contaminated with toxic substances.

But the matter is not confined to Surface Water alone. This contaminated water seeps through the soil and then enters the groundwater. Thus it causes groundwater pollution. And we use that contaminated water for a variety of daily needs, including drinking.


Best Water Purifiers in India – Frequently asked questions

1. Which water purifier brand provides the best after-sales service?

The water purifier is a type of product that requires periodic maintenance. So you will often need technical help. Therefore,
it would help if you chose a brand that gives you reliable after-sales service, without being influenced by the sales representative or various online offers.

After-sales service depends mostly on the availability of service centre in your area, type of service required, availability of the parts, and so on.

Therefore, you need to choose a brand that offers excellent after-sales service in your area. The best way to find this is to do a quick Google search. You can also visit the review section on e-commerce websites where customers share their views about after-sales service.

From our experience, we have seen that in India Kent, Eureka Forbes and Pureit provide satisfactory after-sales service.

2. What is the cost of annual maintenance (AMC) of RO water purifier?

Now, almost all top water purifier brands in India offer annual maintenance service. The cost depends on the brand and the type of model.

Generally, in India, water purifier AMC providers charge between Rs. 3000 to Rs.6000 per annum, which includes periodic replacement of RO membrane, UV and UF filters, activated carbon filters, sediment filters etc.

3. What is TDS controller?

TDS controller regulates the total dissolved solids of the output water of RO water purifier. Generally, RO water purifier lowers 90% TDS of input water. For instance, if input water has a TDS value of 900, then TDS value of the purified output water will be 90.

Firstly, water with very lower TDS value doesn’t taste good. Secondly, it essential to have some minerals and salts in drinking water for your health.

Working principle of TDS controller is straightforward. It divides the input water flow into two parts, one part goes through the RO membrane, and another part goes directly through UF and UV chamber. Hence, the TDS value of the second part remains unchanged. And finally, these two types of water mixed up and come out as output water. As a result, output water contents acceptable TDS value. That is the job of a TDS controller.
