Aqua-semidol / Dolomite

according to EN 1017, Type A
QMS-No. GBT22111

General

Aqua-semidol is a high-quality product that is produced from pure dolomite. By a specific thermal decomposition reaction half the CO2, which in dolomite is contained in the magnesium constituent, is released.
CaC03 * MgC03 -> CaCO3 * Mg0 + C02

Applications

Aqua-semidol is commonly used for filtration and processing drinking water. It de-acidises water by binding carbondioxide and adding calcium and magnesium to the water. Moreover, it is used as a carrier of reagents in desulphurisation of waste gases.
