How to treat hard water?
the treatment of one hard water by a softener is done using an ion exchange resin. This resin created and developed by Culligan captures the magnesium and calcium ions responsible for the formation of tartar and replaces them with sodium ions.
Why know the Water hardness The hardness of one water, or hydrotimetric title, depends on the amount of calcium and magnesium salts it contains. It is calculated in French degrees, symbolized by a “°f” or “°TH”. More I’water will contain calcium and magnesium, the more hardness will be high.
A hard water contains more calcium and magnesium. A water is said lasts when she is rich in dissolved salts, the most important of which are calcium and magnesium. A water low in calcium and magnesium is called sweet.
This resin created and developed by Culligan captures the magnesium and calcium ions responsible for the formation of tartar and replaces them with sodium ions. Hard water is thus rid of what made it harmful to your pipes.
Hardness is expressed in ppm (or mg/L) of CaCO 3 or in French degrees (symbol °f or °fH) in France and Switzerland (not to be confused with the symbol °F, degree Fahrenheit). One French degree corresponds to 10 ppm of limestone representing 10 −4 mol L−1 of calcium, i.e. 4 mg/L of Ca 2+, or 2.4 mg of magnesium per liter of water:
Water loaded with calcium and magnesium is said to be hard. Conversely, water that contains little is said to be soft. In Canada, water hardness is measured in mg/L of CaCO3 (chemical name for calcium carbonate, which can turn into limestone) or in grains per gallon (gpg).
Water hardness in France by department. The hydrotimetric title (TH or GH in German for GesamtHärte), or water hardness, is the indicator of water mineralization. It is due solely to calcium and magnesium ions.
