How to purify water - The Complete Guide

The last decade or so has seen a sharp decline in the drinking water quality. Water purifiers too have gained tremendous interests in the same period. This has resulted in an increase in the interest around water purifiers. The water that we get today, from the municipal bodies, is often laced with alarming levels of dangerous dissolved impurities like rust, salts, heavy metals, chemicals, etc.

Amidst the deteriorating water quality situation, water purifiers have come as a gush of fresh air. There are many water purification technologies available today.  However, most of the water purification technologies eliminate only a few contaminants.

Contaminants present in water can be classified into two categories -

1) Suspended Impurities: These are insoluble impurities which contaminate water. Example - mud, dust, sand, dead insects, rust, mercury, lead, copper, cadmium, etc.

2) Dissolved impurities/ Contaminants: These are soluble particle such as pesticides, chemicals, bacteria, viruses, etc.

Water purification is not a new concept. This process has been going on from a long time. However, with time the traditional water purification methods have become ineffective against many new pollutants.

Listed below are some of the methods used for water purification -

1) Boiling: Boiling drinking water with fuel is the oldest and most commonly practiced household water treatment method. Despite boiling being a laborious that uses up a lot of energy, many organizations recommend it- both, for water treatment in developing countries as well as to provide safe drinking water during an emergency. Boiling only eliminates pathogens and does not remove suspended or chemical pollutants (e.g. arsenic) from drinking water.

2) Cloth filtration: This medieval method of water purification employs a cloth with tiny pores, through which water is passed. The tiny pores prevent suspended impurities from passing through thus providing clean water. However, this method is not effective against dissolved impurities and pathogens.

3) UV water purification technology: A UV-based water purifier is effective against bacteria and viruses but becomes null against impurities like pesticides, rust, heavy metals, salts and harmful chemicals.

4) Kent’s Mineral RO water purification technology: The Mineral RO technology combines the best of both RO & UV technologies, while eliminating the limitations of a single technology. Mineral RO technology offers double purification of RO and UV along with UF — which together remove even the most harmful dissolved impurities including arsenic, fluorides, rust, chemicals, pesticides and other heavy metals. The technology also features a unique TDS Controller that helps retain the essential natural minerals in the purified water. It is one of the best water filters in India.

Why Kent cements its place among the top 5 water purifiers in India

How safe is municipal water that you drink? It is well known that that the water supplied to us by municipal bodies is treated in their water treatment plant. However, this water purification is usually done by chlorination, which is not effective on suspended impurities. The situation worsens during the monsoon when contaminants flow into water reservoirs. Unless water is purified involving the use of a purification system, it cannot be deemed safe. There is a huge difference between treatment of water and its purification. Water purification is important for healthy living.

The government relies on water bodies such as rivers, lakes, ponds, etc., to supply water to the citizens. However, during the monsoon, gushing rainwater carries with it pollutants such as eroded soil, industrial waste, sewage, sediments and agricultural wastes to these water bodies. This situation is ideal for micro- organisms to breed and flourish. Municipal bodies use the tried and tested method of chlorination to reduce high bacterial population, which results in the formation of chlorine byproducts that are harmful for our health. This method is also ineffective against suspended impurities such as dust, sand, dead insects, etc. Many other impurities such as pesticides, insecticides, cysts, etc. also remain unaffected during the process.

These factors make water purifiers more important. Water purifiers such as Kent’s Mineral RO not only remove the suspended impurities but also, eliminate dissolved contaminants.

If you get your water from underground sources such as wells or bore wells, beware, because the water from underground sources is prone to contamination as well. Due to boost in urbanization and rapid industrialization, rain water often absorbs contaminants either in the air itself or on the ground. This water can be laced with high levels of fertilizers, nitrates, pesticides and inorganic salts.  This contaminated water is then absorbed by the ground resulting into contamination of water that is already present underground.

Ground water sources are also known to contain high levels of TDS. High level of TDS is the reason behind bad taste of water. This is another area where Kent has shown its innovative brilliance through its Mineral RO water purifier. This water purifier uses a combination of RO+UV+UF+TDS control to provide clean drinking water. The TDS control present in the water purifier controls the TDS level as per your requirement. No wonder that with all these amazing features, Kent’s Mineral RO is widely considered as one of the top 5 water purifiers in India.


Kent also offers a number of other brilliant water purifiers. Take for example the Kent’s 0% water wastage water purifier. This water purifier breaks away from the long tradition of RO water purifier. This unique water purifier does not waste water like the traditional RO water purifier. Must say that Kent has a knack of producing innovative and effective water purifiers. 

All you must know about domestic RO water purifier

What comes to your mind first when someone says, water purifier? Umm, maybe a lot of questions bombard your mind when you think about which is the brand I should go for, what will be the technology and the last but not the least what will be the price? It is obvious that these questions will arise when you are buying a domestic RO water purifier, and why not, in the end you do not want to take chances when it comes to the quality of water you are going to drink.

Pure clean drinking water isn’t available easily these days. Every household and commercial space
desperately needs a purification technology which effectively removes harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride, etc apart from other impurities like bacteria and viruses. At the same time, the purifier should retain essential natural minerals in drinking water. It should also work efficiently over a long period of time.

So the first question to keep in mind while buying a water purifier is — Can your purifier eliminate those harmful substances? If yes, then you will have to search for the technology that it uses and go through the process and authentication of that technology. Many brands boast about the latest and most efficient RO technology for water purification and one of them who actually delivers it is Kent.

Kent’s Mineral RO technology offers multi-stage filtering of water by combining active carbon along with sediment filter that later sends water to a combination of RO+UV+UF+TDS control to provide clean drinking water.

Conventional RO purifiers while removing dissolved impurities also remove essential natural minerals from the water. Whereas in KENT water purifiers, while dissolved impurities are removed, essential natural minerals are retained.

Water purification capacity is also an important factor when it comes to purchasing a water purifier. The amount of water consumption in your home or office must be considered properly before purchasing a water purifier.

The next thing a person will look for while purchasing a water purifier, is the cost of the device. People are always on the lookout for a low cost water purifier. However, it is not the most important factor that should be considered when purchasing one of these devices.

How badly do we need water purifiers?

Water is the most essential element in our lives. Yet, the truth of the matter is that every year there are millions of people who lose their lives due to water-related causes. Water that contains impurities and contaminants results in water becoming poisonous. In India, with our sad state of affairs, it is an understandable fact that many people across the board receive impure water that is consumed by adults and children alike. Many young children are affected due to the consumption of contaminated water which may also result in an increasing proportion of deadly water borne diseases occurring in their families. Water hardness, bad taste, colour and odour were some of the other major issues that are seen in the water of our country.
