Calcium hydroxide or slaked lime and the specific products derived from it are of great benefit, it is reliable and especially effective for applications such as accelerating the kinetics of reactions, increasing the efficiency of absorption and guaranteeing a high degree of capture of gaseous pollutants. Moreover, a correct combination of the above-mentioned parameters of calcium hydroxide means that highly reactive products can be offered. Therefore, among the beneficial effects that the use of calcium hydroxide brings is that of pH regulation, as well as in encapsulating metals and disinfecting, without forgetting that it also reacts with silica, creating pozzolana structures.
Calcium hydroxide can be found in the food industry providing calcium and as a pH modifier, as well as in the management of gases, as it has a high effectivity in the capture of acidic pollutants from industrial smoke and vapours. It is also an additive in feeds improving animal nutrition, and is used in animal-pens for its disinfecting power, lowering the number of pathogens and virus. In the sugar-industry it can be used to precipitate out impurities and to obtain purified sucrose. It also brings benefits in sludge treatment as it is an exceptional aid in the elimination of micro-organisms and bacteria which at the same time neutralizes bad smells. Its properties are especially useful for water treatment, because it acts as a clarifier, a coagulant, a neutralizer and for the precipitation of dissolved pollutants.
Its characteristics do not only bring advantages when compared to other chemical products because it also gives a technological touch to this product, which above all, has outstanding uses in environmental applications.
