7 Types of Water Depending On the Fixed Residue LevelFilter For Fridge
Depending on the fixed residue, the waters can be divided into different categories. When we speak of a fixed residue, we refer to the set of residual substances deriving from boiling water at a temperature of 180 degrees. Therefore, diuretic oligomineral waters, medium mineral digestive waters, bicarbonate waters, sulphate waters, chlorinated waters, calcium waters, magnesium waters, fluorinated waters and ferruginous waters can be indicated.
Diuretic Trace Mineral Waters
Going into detail and taking into consideration the different types, the diuretic oligomineral waters are characterized by their reduced sodium content and their ability to prevent kidney stones. The digestive medium mineral waters are useful for the diets of subjects who practice sports at a competitive level , since they are precious for the reintegration of mineral salts, especially during the summer season, when it is warmer and warmer. Sweat more.
The bicarbonate waters, which are considered useful for dab and eliminate the gastric acid, can be considered among the most widespread, since the bicarbonates are prevalent in the soil, together with the magnesium, sodium, sulfates and calcium, to in turn present in these waters. They are used, among other things, in hydropinic therapy, as well as as drinks. They derive from the crossing of limestone rocks and can present elements such as iodine, bromine and iron which, depending on the case, are able to give them appreciable significant biological characteristics also from a therapeutic point of view.
In sulphate waters, sulfur in hexavalent form is present in above-average quantities, which is represented by sulfuric ion in natural hydromineral solutions. Calcium sulphate enriches the waters when they cross the rocks and the chalk banks.
The calcium waters are, however, rich in calcium: are recommended (always under the supervision of a doctor) who wants to prevent osteoporosis effects, since this mineral – as is known – is a very valuable protective factor against such a disturbance.
The chlorinated water are so called because they have a chloride content of not less than 200 milligrams per liter. These substances, which include sodium chloride, have a rebalancing effect on the intestinal system, which is also exerted on the liver and biliary tract. It should be borne in mind, however, that chlorinated waters should not be consumed by subjects suffering from kidney problems.
Waters whose magnesium content is over 50 milligrams per liter are defined as magnesia. This mineral salt, as known, is able to promote the prevention of pathologies of the heart and diseases of the circulatory system, but at the same time has beneficial effects compared to the functioning of the nervous system.
The ferruginous waters can be distinguished, in turn, in waters bicarbonate ferrous, ferrous sulfate in water and ferric sulphate waters. In ferrous bicarbonate waters, modest quantities of bicarbonate are found: the precipitation of iron as hydroxide is caused by the action of oxygen, which makes them unstable. The arsenic content is higher, however, in ferric sulphate and ferrous sulphate waters, whose pH level is lower than or even lower than 1 due to phosphoric acid and sulfuric acid.
