How can carbonate and noncarbonate hardness be calculated?
Carbonate and noncarbonate hardness calculations.
Carbonate and noncarbonate hardness can be calculated if the total hardness and total alkalinity values are known:
|Hardness and Alkalinity Relationship||Noncarbonate Hardness mg/l as CaCO3||Carbonate Hardness mg/l as CaCO3|
|Total Hardness is less than or equal to
|= Total Hardness||0|
|Total Hardness is greater than Total Alkalinity||= Total Alkalinity||=Total Hardness - Total Alkalinity|
