The chemical formula of Water is H2O, however, water is a much more complex combination of many solvents. The composition of water is influenced by a wide range of factors. One being the geological factor that includes the atmospheric interaction, the minerals present in the soil, contact with the living and organic matter.
However, most of the artificially produced water is completely demineralised. Demineralisation implies water which is void of dissolved minerals and salts as a result of distillation, membrane filtration (reverse osmosis or nanofiltration), electrodialysis or any other technology.
In demineralisation or low mineral water, all the dissolved substance present are eradicated fully. However, this should not be done because some of the dissolved components are essential minerals and micronutrients. (Water contains essential minerals such as Magnesium, Calcium, Sodium, Potassium etc). These are extremely vital for the maintenance of the overall holistic health of an individual.
Water purification, therefore, becomes an essential process to ensure that the drinking water has these minerals. Reverse Osmosis today is a widely used purification technique. Water is pressurised and forced through a semi-permeable membrane. This removes the pathogens, impurities along with the mineral ions. Therefore, RO water is pure but demineralised. People who consume RO based water or the usual bottled water needs to realize that this is not the best choice.
It has been scientifically confirmed that the consumption of Reverse Osmosis water is extremely detrimental to the human health. Water obtained from RO filtration process has a low pH value i.e. it is acidic. Prolonged consumption of RO water can cause gastrointestinal troubles and enhanced risk of kidney disorders.
RO water is one of the major causes of gastric disorders. This is because it is slightly more acidic than pure water. It has a lower pH value which ranges from 6.0-6.5 pH. The pH level of normal pure water is around 7.5 pH.
