Dgh water
WebCarbonate hardness, is a measure of the water hardness caused by the presence of carbonate ( CO2−. 3) and bicarbonate ( HCO−. 3) anions. Carbonate hardness is usually expressed either in degrees KH ( dKH) (from the German "Karbonathärte" ), or in parts per million calcium carbonate ( ppm CaCO. 3 or grams CaCO. Degrees of general hardness (dGH or °GH) is a unit of water hardness, specifically of general hardness. General hardness is a measure of the concentration of divalent metal ions such as calcium (Ca ) and magnesium (Mg ) per volume of water. Specifically, 1 dGH is defined as 10 milligrams (mg) of calcium oxide (CaO) per litre of water. Since CaO has a molar mass of 56.08 g/mol, 1 dGH is equivalent to 0.17832 mmol per litre of elemental calcium and/or magnesium ions.
