Calcium Carbonate Precipitation Potential

Calcium Carbonate Precipitation Potential John A. Wojtowicz Chemcon Although the calcium carbonate saturation index is applicable to swimming pool water balance calcula- tions, 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.

Factors Affecting Precipitation of Calcium Carbonate

calcium carbonate precipitation potential (CCPP) discussed in a previous article (Wojtowicz 1996). However, the quantity of precipitation was greater than predicted due to loss of carbon dioxide from solution. Since loss of carbon dioxide increases pH, it also raises the saturation index, increasing the CCPP. The fact that the pH was observed to de-

Procedure for Calculating the Calcium Carbonate ...

28.12.2020  Carbonate Precipitation Potential (CCPP) is applicable. The CCPP is defined as the amount of CaCO3 that can theoretically precipitate or dissolve from the water in order to reach equilibrium with a solid CaCO3 phase [9]. Other indicators of CaCO3 saturation, such as the Langelier Saturation Index and Ryznar Index, only predict a thermodynamic driving

The Water - Calcium Carbonate / CCPP

CCPP is an acronym that stands for Calcium Carbonate Precipitation Potential. It is the calculated mass of calcium carbonate expected to precipitate or be dissolved by particular water. It is not measured directly, but rather derived through complex mathematical calculations using parameters such as pH, temperature, calcium and alkalinity concentrations. It is expressed as milligrams per litre (mg/L)

CCPP - Hydro-Land

The calcium carbonate precipitation was accompanied by a decrease in pH , reduction of hardness as 1 mole (and 2 equivalents) of total alkalinity , for each mole of calcium carbonate precipitate. The potential for calcium carbonate precipitation increases with saturation index and intensity of the buffering effect of water. The intensity buffer is a function of pH and total alkalinity.

The process of precipitation of calcium carbonate occurs in three stages. In the first step, calcium ions combine with carbonate ions to form calcium carbonate (CaCO 3) microparticles. Next, CaCO 3 particles combine in micro-crystals that serve as crystallization centers for the remainder of the solution. Crystal aggregates grow and
