Safe drinking water is a must for our healthy living. many times if water is not purified well we have to suffer from waterborne diseases like dysentery, cholera etc. Thanks to our technology that we get best filters at our home. But, is that not a big question for us to choose the best water purifier. No doubt, if we are having water purifier than our water must be potable and safe for drinking. But do all water purifiers remove micro-biological lives from the water we drink and give us essential nutrients? No, all are not equal and some do filter the essential nutrients from water.
About 37.7 million people of India are facing problems regarding unpurified water. Bacteria (E coli, Shigella, Vibrio cholerae), viruses (Hepatitis A, poliovirus, rotavirus) and parasites (E. histolytica, Giardia, hook worm) present in contaminated water causes water borne disease. These diseases can be cured with medicines and antibiotics. But the presence of arsenic and other heavy metals such as cadmium, zinc and mercury leads to metabolic disruption, damage the nervous system and kidneys forever. They are also known to cause cancers of colon, liver, kidneys and lungs.
On research it was found that in some of the parts of India like West Bengal, Jharkhand, Bihar, Uttar Pradesh, and Chhattisgarh states have been reported to be affected by arsenic contamination in groundwater. Water contaminated with arsenic can lead to kidney problems, stones, cancer. Arsenic in drinking water is absorbed through the intestine into the bloodstream through which it reaches the various organs. The human body normally gets rid of smaller amounts of arsenic through urine. For drinking pure water we must use water purifier as we can’t rely on tap water. In many cases doctor have said that water purifier removes natural minerals from the water. But if tap water contains more impurities then use of water purifier is a must. Now the question is how to choose the best water purifier?
To choose the best purifier first you have to check your water quality, good if tested in lab. If you are living in big cities such as Delhi, Mumbai, etc. your tap water is generally safe with regards to total dissolved solids (TDS) and heavy metals but not from pathogens. Your best bet would be UF or RO water purifiers.
Aquaguard Geneus RO + UV +UF, Kent Grand RO + UV, Tata Swach Viva Silver UV + UF, Aquaguard Enhance RO, Pureit Classic Gravity Water Purifier, are some of the water purifiers which are available in India. There are mainly 3 different types of purification technology present in the market.
RO (Reverse Osmosis): In this method water is passed through a semipermeable membrane under high pressure to remove dissolved impurities. RO water purifier removes bacteria, viruses, germs and dissolved chemicals from water as its RO membrane is so small that it can also remove dissolved salt from the water. RO purification is mainly used for Salty or Hard water. This technique requires electricity to purify water and produce lots of wastewater.
UV (Ultra-violet): This method of water purification is used to remove germs, bacteria and viruses from water. This technique uses a Rod producing ultra-violet radiations which are made to pass through water so these radiations can kill germs and viruses present in water. This method also requires electricity but do not generate wastewater.
UF (Ultra-filtration): In this method water is passed through microfibers threads which remove salts from water. This method is adopted by plants and trees using its roots as fibers to filter groundwater. The advantage of the UF water purifier is that it works without electricity and is sure to filter out any disease causing germs, including the smallest of viruses. The UF membrane is also so small that it will filter out all dust and other particles and make the water safe to drink.
Therefore RO water purifier that comes with TDS regulator is considered the best type of water purifier that can retain the natural minerals and it also enhances the taste of water.
