Reverse Osmosis: Use or not to use? Enviro Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules and larger particles from drinking water. Enviro RO removes inorganic minerals which are unhealthy and healthy too3. Improvement in Enviro RO technology including advanced membrane material, module and process design, and energy recovery has led to cost reduction which in turn gaining interest to its commercial as well as household applications. In this article, the applications of Enviro RO, its advantages, and limitations are being discussed especially related to health. By purifying drinking water, we can minimize the exposure to contaminants and may potentially reduce our allergy symptoms and chances of getting infections. Though, both distilled and reverse osmosis water are demineralised, but having demineralised purified water is harmful or not to your body, one needs to decide it based on the situations and place where one lives. Advantages Enviro RO reduces sodium and other minerals from hard water. It also removes toxin such as lead, mercury, Fluoride, Arsenic, Chlorine which may impart bad effect to health of the human being All these minerals has negative effects in one or the other way. One could still have a high level of total dissolved solids, which will impact the taste. Bottled water is expensive, additionally those plastic bottles create a lot of solid and non biodegradable waste as they all too often go non recycled and end up in landfills. A Enviro RO system will pay fcr itself in lesser time because it will cost hardly some paisa per glass depending upon the purchase and brand'. Secondly, whenever we need clean drinking water, it's just a tap away, hence reducing the cost. The impurities in home's water are going to affect the taste of the food and it requires more time to cook as total dissolved solvents delay the process of cooking. lf you're using municipal tap water for cooking, there's a good chance you have too much chlorine in it. This not only cause food to taste odd, it discolors itas well. Enviro RO water filter is great for removing commonly found Cryptosporidium in lake, river and public supply water, hence serves as bacterial decontaminator Other thing is having crystal clear ice cubes. Water crystalizes as it freezes. Ice forms from the outside in, and as this happens the impurities are forced to the center of the ice cube, resulting in the cloudy appearance. Ice cubes made with an Enviro RO will keep your drinks cool longer without watering them down as much. Disadvantages: In reality, one should be getting most of the mineral for body needs from the food we eat, but the minerals from water are also important. The only thing skeptics of Enviro RO can point to as a disadvantage is that reverse osmosis systems filter out most of the minerals, which can be valuable to health. Some studies shown having a minimum mineral content protects cardiovascular system. Enviro RO water purifier removes dissolved impurities it also removes natural mineral such as iron, magnesium, calcium and sodium which are essential to the human body and cause a mineral deficiency in the body. Recent studies shows these minerals are essential for function in body. As natural minerals are removed water gets de-mineralized as a result water taste is affected and altered1 Enviro RO water purifier does not kill waterborne disease-causing bacteria and viruses10. There is high probability that microorganisms can pass through Enviro RO membrane, so it is advisable to pass Enviro RO water through the UV water purifier to treat micro organisms or some alternate method can be used. Drinking Enviro RO water can cost you time, energy and money too. Enviro RO water purifier takes too long to the purification of water. Approximately much more water compared to filtered out water flushed down as waste water. Adding on to it, its cost. Compared to counterpart water purifiers, UV and RO water purifier consumes much more electricity. Chlorine in the water can damage RO membrane. It makes small pores of Enviro RO membrane, clogged and makes drastic reduction in performance. On breakage of membrane dissolved salts, bacteria, viruses can easily pass through Enviro RO membrane. It Is advisable to replace Enviro RO membrane once in a year. However, no mechanism is there, to know when to replace Enviro RO membrane. The water is usually acidic. One of the primary reasons RO water is unhealthy as removing the minerals makes the water acidic (often well below7.0pH). Drinking acidic water will not help maintain a healthy pH balance in the blood, which should be slightly alkaline. Furthermore, the dissolved mineral found in drinking water are organic, which means your body has a difficult time absorbing them10. This negates any potential health benefits. Some critical containments are still there like volatile organic containments, chlorine, pharmaceuticals and a
