The most important resource required to sustain any form of life either for human beings, plants and animals is water. It is also one of the most abundant resources. It is a known fact that almost 70% of the total earth is covered with water bodies. However, the harsh reality is thatyou have access to only about 1% of potable freshwater. This is precisely the reason why water is considered a significantly scarce resource.
Since time immemorial, safe, clean and pure drinking water has been a supremeneed for the life of human beings. However, with the continuous spread of technology and industrial growth, the pollution levels are steadily increasing across the country. This has hampered the quality of water the most, more than the other resources like land and air. What makes water a consistent carrier of all the harmful chemicals and pollutants is the fact that it is a very good solvent. The consequenceof this property is that water is getting polluted and isbecoming unfit for use.
This situation is even more alarming in a developing country such as India. If the water that you drink or use for other than domestic purpose is contaminated or impure, it can cause serious illnesses.Some of the most commonly reported waterborne illnesses are Diarrhea, Worm Infections, Gastrointestinal Problems, Nausea, Intestinal or Stomach Cramping, Intestinal or Stomach Aches and Pains, Dehydration, Cancer, Heart Disease and others. In addition to the perils of contamination of freshwater, India has a widespread natural presence of harmful chemicals like fluoride and arsenic in groundwater.
All these should make you realize that having a purifier is anabsolute necessity in India.There isno lackof waterpurifiers out in the market and choosing the best one is a very difficult task. While all water purifiers have something unique or the other, we bring you some of the crucial components or parameters that would help you in your decision.
The water purifiers are broadlyclassified on the basis of the water treatment technique they use.
Distillation Water Purification:
The basic water purifiers use the technique of distillation. As per the age old practice, boiling the water and cooling the resultingvapor,will give you pure water as the impurities are left behind. This is a trusted mechanism, but thework rate of distillation water purifiers is slow as compared to the others. Hence, you should select advanced water purifiers that make use of modern equipment and purify your drinking watercomparatively faster.
Reverse Osmosis (R.O.) is one of the most widely accepted methods to give you pure drinking water. In RO purification, the water is passed through a semi-permeable membrane that eliminates the impurities such as heavy metals, pesticides, microbes, etc. and pure water is filtered out. The only drawback of RO Purifier is that the membrane is susceptible to chlorine and has to be guarded with carbon filters.
UV Water Purification
UV Water purifiers use the technique of Ultra Violet radiation to eliminate bacteria, viruses,etc. It is very cost-effective system and is also considered safe for consumption and good for your health. The most important thing to notice here is that UV Water purifiers don’t leave behind chemicals or by-product in the final output of water.
Gravity Water purifiers
Gravity Water purifiers use the technique of carbon technology to provide you pure water, instead of electricity. The final output of water is devoid of any bacteria or harmful chemicals and is also a cost-effective option.
All these reasons and classification should be considered selecting the best water purifier.
