 ## ﻿how to calculate the total hardness of boiler water ### Water Treatment Storage and Blowdown for Steam Boilers

Total permanent water hardness is calculated with the following formula: TOTAL PERMANENT HARDNESS = CALCIUM HARDNESS + MAGNESIUM HARDNESS. The calcium and magnesium hardness is the concentration of calcium and magnesium ions expressed as equivalent of calcium carbonate. The molar mass of CaCO3, Ca2+and Mg2+are respectively 100,1 g/mol, 40,1 g/mol and 24,3 g/mol.

Jan 16, 2020 · MCaCo3/MCa = 100,1/40,1=2,5. MCaCo3/Mmg = 100,1/24,3 =4,1. This means that the overall permanent water hardness which equals CaCO3 can be determined with the formula below: (CaC03) = 2,5 . (Ca2+) + 4,1 (Mg2+) So if you looking for "how to calculate water hardness formula", you can use the one above.

Jul 30, 2012 · It takes 17.1 PPM to equal 1 GPG. If a test for hard water is measured in parts per million or milligrams per liter you can take the total hardness level and divide it by 17.1 to get hardness in grains per gallon. For example if your water test shows 250 mg/L hardness you actually have 14.62 grains per gallon.
