Question
How can carbonate and noncarbonate hardness be calculated?
Summary
Carbonate and noncarbonate hardness calculations.
Answer
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 Alkalinity
= Total Hardness 0
Total Hardness is greater than Total Alkalinity = Total Alkalinity  =Total Hardness - Total Alkalinity
