Water Hardness Calculation
Measuring Water Hardness
WEB Total water hardness is a measure of the concentration of multivalent cations in water calculated in terms of CaCO3 (calcium carbonate) concentration.
WEB The easiest way to calculate water hardness is to use a water hardness calculator tool. Simply enter the calcium carbonate hardness.
Formula for Water Hardness Calculation
WEB Water hardness is typically measured in units of parts per million (ppm) or milligrams per liter (mg/L) of calcium.
Their are two types of water hardness: Temporary hardness is caused by the presence of calcium and magnesium bicarbonates, while permanent hardness is caused by the presence of calcium and magnesium sulfates, chlorides, and nitrates. This calculator determines the permanent total hardness.
The water hardness is calculated by simply adding the concentrations of calcium and magnesium.
