This increases the cost of domestic water heating by about fifteen to twenty percent.Īnother negative effect of lime scale is that it has damaging effects on household machinery, such as laundry machines.
Due to this lime scale build-up, pipes are blocked and the efficiency of hot boilers and tanks is reduced. Hard water causes a higher risk of lime scale deposits in household water systems. Water softening can prevent these negative effects. When water is hard, it can clog pipes and soap will dissolve in it less easily. Water softening is an important process, because the hardness of water in households and companies is reduced during this process. The best way to soften water is to use a water softener unit and connect it directly to the water supply.Ī water softener is a unit that is used to soften water, by removing the minerals that cause the water to be hard. Iron ions may also be removed during softening. Water softening is a technique that serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Hard water is known to clog pipes and to complicate soap and detergent dissolving in water. When water contains a significant amount of calcium and magnesium, it is called hard water. In many industrial applications, such as the drinking water preparation, in breweries and in sodas, but also for cooling- and boiler feed water the hardness of the water is very important. This is the cause of the fact that soap doesn't really dissolve in hard water.ġ.2 Which industries attach value to hardness of water? Because of their presence, other positively charged ions will dissolve less easily in hard water than in water that does not contain calcium and magnesium. Magnesium and calcium are positively charged ions. The degree of hardness of the water increases, when more calcium and magnesium dissolves. These are especially the minerals calcium and magnesium.
When water is referred to as 'hard' this simply means, that it contains more minerals than ordinary water.
