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.
