Although the calcium carbonate saturation index is applicable to swimming pool water balance calculations, it is only a qualitative indicator of calcium carbonate precipitation since it does not indicate the extent of precipitation that can occur at positive values of SI. Utilizing the mathematics of aqueous carbonate and cyanurate equilibria allows calculation of the quantitative calcium

2017-5-12 precipitation increases with increasing alkalinity at a given SI and decreases with increasing pH. The change in precipitation with alkalinity and pH is due to a change in buffer intensity which varies directly with alkalinity and inversely with pH, in agreement with calcium carbonate precipitation potential (CCPP) theory (Wojtowicz 1996).

The calcium carbonate (CaCO3) precipitation potential (CCPP) can predict the potential for corrosion and lime scaling in drinking water systems. CCPP can be calculated by different standards, but none of these consider all of the conditions in drinking water systems where temperatures can reach 100 °C and the water exchanges CO2 with the atmosphere.
2014-4-25 Precipitation of calcium carbonate, thus, constitutes not only a decrease in calcium hardness and alkalinity, but also pH. Note that hardness and two mole equivalents of alkalinity (10 °F) is consumed for each mole of precipitated calcium carbonate CaCO 3. Calculation of Calcium Carbonate Precipitation Potential.
2019-5-25 ABSTRACT: Amorphous calcium carbonate is often the first phase to precipitate from solution during the mineralization of calcium carbonate, before the formation of one of the crystalline polymorphs. In vivo, this phase is believed to be essential for the manufacture of minerals displaying nonequilibrium morphologies. The precipitation of this
