How is German hardness calculated?

How is German hardness calculated?

The most common unit in Germany is ° dH (degree German hardness). In other countries is measured with English or French degrees of hardness. Physically, the unit mmol / l (millimoles per liter) is the correct unit….Waterhardness Calculator.

Name Value Unit
Millimoles per liter 0 mmol/l
Parts per million 0 ppm
French degree hardness 0 °fH

How do you convert GPG to mg l?

One gpg (1 gpg) is equivalent to 17.1 mg/l.

How do you calculate CaCO3 equivalent?

calcium carbonate (CaCO3) equivalent Alkalinity test results are usually reported as mg/L CaCO3 equivalents. To convert chloride to CaCO3 equivalents, multiply the concentration of chloride ions in mg/L by 1.41, and for sulfate, multiply by 1.04.

How do you calculate HV?

The Vickers number (HV) is calculated using the following formula: HV = 1.854(F/D2), with F being the applied load (measured in kilograms-force) and D2 the area of the indentation (measured in square millimetres). The applied load is usually specified when HV is cited.

How do you calculate carbonate and Noncarbonate hardness?

Carbonate hardness (mg/L) = Alkalinity (2a) When alkalinity > Total hardness: Carbonate hardness (mg/L) = Total hardness (2b) The amount of hardness in excess of this is called “Non-carbonate hardness (NCH)”.

What is mg CaCO3 L?

(mg/L as CaCO3) (mg/L as CaCO3) ALKALINITY. Alkalinity is a measure of water’s capacity to neutralize acids, and is important during softening. Alkalinity is the result of the presence of bicarbonates, carbonates, and hydroxides of calcium, magnesium, and sodium.

What is ug/l in ppm?

For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l). A measurement of 6 mg/L is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/L.

Why is alkalinity measured in CaCO3?

Why is alkalinity reported as “mg/L as CaCO3”? Units of mg/L are a “mass dissolved in a liquid.” Reporting alkalinity as “mg/L as CaCO3” specifies that the sample has an alkalinity equal to that of a solution with a certain amount of calcium carbonate (CaCO3) dissolved in water.

How do you calculate alkalinity?

Alkalinity is oftentimes measured in seawater and drinking water, and can be calculated as the sum of ion concentrations [HCO3-]+2x[CO3(-2)]+[OH-]-[H+]. To complete this calculation, you will need to perform a titration on your sample, from which you can derive the alkalinity of your sample.
