The simple definition of water hardness is the amount of dissolved calcium and magnesium in the water. Hard water is high in dissolved minerals, largely calcium and magnesium. You may have felt the effects of hard water, literally, the last time you washed your hands. Water hardness or softness is measured using grains per gallon (gpg), where one grain is equal to 0.002 ounces of calcium carbonate dissolved in 1 gallon of water. 0-3 gpg is considered soft water. 3.5-7 gpg is considered moderate and ideal. >7.5 gpg is regarded as hard water and should be treated with a water softener.

Hard water is water containing high amounts of mineral ions. The most common ions found in hard water are the metal cations calcium (Ca 2 +) and magnesium (Mg 2 +), though iron, aluminum, and manganese may also be found in certain areas. These metals are water soluble, meaning they will dissolve in water. The relatively high concentrations of ...

Water flows over the resin surface, dissolving the sodium. The calcium, magnesium and other cations precipitate onto the resin surface. Sodium goes into the water, but the other cations stay with the resin. Very hard water will end up tasting saltier than water that had fewer dissolved minerals. Most of the ions have been removed in soft water ... PPT A Guide To Hard Water In Your Home PowerPoint Presentation ID
