John A. Wojtowicz Chapter CarbonatePrecipitation PotentialJohn A. WojtowiczChemconAlthough the Calcium Carbonate saturation indexis applicable to swimming pool water balance calcula-tions, it is only a qualitative indicator of calciumcarbonate Precipitation since it does not indicate theextent of Precipitation that can occur at positive valuesof SI. Utilizing the mathematics of aqueous carbonateand cyanurate equilibria allows calculation of thequantitative Calcium Carbonate Precipitation poten-tial (CCPP), , the equivalent Calcium carbonatesupersaturation. Precipitation of Calcium Carbonate isaccompanied by a drop in pH and a reduction inhardness of 1 mol and in total alkalinity of 2 equiva-lents for each mol of Calcium Carbonate Calcium Carbonate Precipitation Potential increaseswith saturation index and buffer intensity.
