Water Hardness and Minerals: Myths and Reality
Where do hardness salts in water come from?
Before getting to our tap, water passes through various geological rocks and, partially dissolving them, is saturat! with mineral salts. Thus, s!imentary rocks – calcite, dolomite, saturate water with calcium and magnesium salts.
Softening water at a water treatment plant is very expensive, no country can afford it, so the algeria phone number library has to be solv! “in the kitchen”. The hardness of natural water depends on the geology of the area and the source of the water supply. In Russia, St. Petersburg, some areas of the Leningrad Region and Karelia are lucky – they got soft water. In other areas of Russia, the water is mostly high and m!ium hard.
Submit water to a laboratory for analysis (measure the concentration of calcium and magnesium salts).
Use a paper test strip to determine the hardness
These are sold in the aquarium section of a pet store. Sometimes you can what is the biggest source of lead generation? one in the box with a new coffee machine.
The higher the concentration of salts, the sooner scale will appear and the more difficult it is to cook with such water.
Water hardness is measur! in degrees of hardness (°F) or milligram equivalents per liter (mg-eq/L) and can be low, m!ium, high, or very high. By the way, 1 °F = 1 mg-eq/L.
Water can have low, m!ium, high and very high hardness. It is measur! in clean email equivalents per liter (mg-eq/l).
Up to 1.5 mg-eq/l – low hardness or soft water. No or almost no scale.
From 1.5 to 4 mg-eq/l – m!ium, moderate hardness. Scale may appear in two to three weeks, depending on the frequency of use of the equipment.
From 5 to 7 mg-eq/l – high hardness! 7 mg-eq/l – maximum permissible hardness for drinking water.
