Pure and healthy drinking water is one of the most important human requirement for healthy living. But not all the water that comes in taps is pure and healthy. Regardless of how clean your drinking water is, there is no guarantee that it is pure and germ-free. It could have contaminants like microscopic bacteria, germs, lead and arsenic or a very high level of TDS (Total Dissolved Salts). That cause diseases
According to one survey report in India, impure drinking water causes 77% of diseases like typhoid, dysentery, chorea, hepatitis, jaundice and so many others. Many people think that boiling water before them drink is good enough. But the truth is boiled water only provides protection against microbial contamination which caused by bacteria and virus. It does not remove other harmful chemicals/ contaminants like mercury, lead, copper, germs, pesticides and herbicides.
SO that is why a good Water Purifier in India is a necessary for pure and healthy drinking water. But many people struggle with many questions. Which water filter would you select? Which is best UV, RO, and UF?
Your decision should be based on little bit research. Firstly you need to know is what is your water condition is. Once you know this what kind of water purifier you need to buy, here what you need to know about some technologies available in market.
Reverse Osmosis (RO):- At present time Reverse osmosis water purifiers India is widely demanded. If you live in area where you get hard water then RO purifier is best. This purification system are designed to reduce the TDS content from water. RO allows cross filtration of water, where the impurities are caught in the membrane. The impure water goes one way and the pure and clean water goes another way. RO purifiers remove more than 90% of the TDS and all impurities like bacteria, virus, protozoa, coliform, physical and chemical contaminants etc.
Ultra Violet (UV):- UV water purifiers are best for soft water like that from rivers or lakes and where the TDS level is below 500mg. UV purifier kills the bacteria and viruses present in the water. this method destroys almost 99.99% of all bacteria and viruses that cause diseases. But this method ineffective against lead, chlorine, asbestos and other organic chemicals. It doesn’t alter the organic chemical of water so it cannot be used for hard water.
Ultra filtration (UF):- UF purification method removes dissolved solids present in the water. Many a times it is used as a pre- treatment step before Reverse Osmosis (RO). This method is best for some area where the TDS level is below 500 mg/liter.
