Study about an innovative system of treatment and re-mineralization of drinking water

Very often, for the domestic or relating to co-ownership system maintenance, for the pipelines state, foe the presence of reserves or autoclaves and for water characteristics (such as hardness) it happens that supplied water does not face consumers expectations. It follows a great increase in consuming bottled water or in exploitation of home treatment systems (partial demineralization and purification). To this regard, it was clear from the very beginning that desalinated or demineralised water without further enrichment with some minerals might not be fully appropriate for consumption because: demineralised water is highly aggressive and if untreated, drinking as well as its distribution through pipes and storage tanks would not be possible; distilled water has poor taste characteristics; preliminary evidence was available that some substances present in water could have beneficial effects on human health. Drinking water, in fact, should contain minimum levels of certain essential minerals and the issue is relevant not only where drinking water is obtained by desalination (if not adequately re-mineralised) but also where home treatment or central water treatment reduces the content of important minerals and low-mineral bottled water is consumed. Although drinking water manufactured by desalination is stabilized with some minerals, this is usually not the case for water demineralised as a result of household treatment. Even when stabilized, the final composition of some waters may not be adequate in terms of providing health benefits. Although desalinated waters are supplemented mainly with calcium or other carbonates, they may be deficient in magnesium and other microelements. Furthermore, the quantity of calcium that is supplemented is based on technical considerations (i.e., reducing the aggressiveness) rather than on health concerns. The goal of this research, deals with the study of a innovative system for re-mineralization of treated drinking water (filtered, refrigerated and if necessary added with carbonic acid) for domestic and collective alimentary consumption.
