Calculate the saturation pH for calcium carbonate.
\begin{equation} pH_s = pK'_2 + pCa^{2+}-pK'_s -log(2 \times \left[Alk \right]) -log\gamma_m \end{equation} \begin{equation}
Module: WaterChemistry
\begin{equation} pH_s = pK'_2 + pCa^{2+}-pK'_s -log(2 \times \left[Alk \right]) -log\gamma_m \end{equation} \begin{equation}
Function: WATERCHEM_phscalcium(t,tds,ca,hco3)
Parameters:
- t, temperature - ºC;
- tds, Total Dissolved Solids - mg/l;
- ca, concentration of calcium hardness, mg Ca/liter;
- hco3, concetration of HCO3- (alkalinity), mg CaCO3/liter.
Sample code:
from WaterChemistry import *
tds = 300 # mg TDS/liter
ca = 50 # mg Ca/liter
hco3 = 100 # mg CaCo3/liter (Alkalinity)
t = 20 # oC
phs = WATERCHEM_phscalcium(t,tds,ca,hco3)
print("phs:",phs)
Result:
phs: 7.914650556552682
