A water softener is an appliance that is used to treat hard water by removing calcium and magnesium metals as well as iron, manganese, and radium elements from the drinking water. These minerals harden the water and cause damage to home appliances, skin, clothes, surfaces. The most common method of water softening is the ion exchange.
Water that contains an excessive amount of minerals, more than 200 mg of calcium carbonate /l is considered hard. In large quantities, these hardness salts in the water create limescale and soap scum in boilers, water-pipes, laundry machines, and bath water.
The unsoftened water goes through rasen beads the resin tank. Inside of the tank, the hardness ions in the water are replaced by sodium ions (salt) that are electrostatically bound to the beads.
The most common types of water softeners use an ion exchange process to remove the hard salts from the water supply. The process involves pumping the water supply through a resin matrix that traps the calcium and magnesium ions that cause the hardness and trading them with potassium and sodium ions. The ion exchange water softening process can remove almost all of the magnesium and calcium from the water system.
After a significant amount of water goes through the softening process, the resin beads become worn out and do not have enough supply of sodium to keep the water softening process going. The beads need to be regenerated.
The process usually occurs once a day. In this procedure, the softener regenerates the resin by flushing it with sodium chloride solution. The magnesium and calcium go to the drain, and the fresh sodium ions are now on the resin and prepared for the next softening cycle. Meanwhile, the softened water enters the home.
The regeneration is usually activated automatically by the mechanical water flow meter or the electronic time of the water softener. However, once a month the machine should be refilled with salt in the form of small blocks, tablets, or granules.
The water produced by the softeners does not hold any magnesium or calcium but does have an addition amount of sodium-8mg/L per grain of hardness. Water softening process reduces the hardness of water by less than 10 mg/L.
Removal of Limescale
A significant amount of calcium and magnesium minerals in the water supply cause limescale-white, flaky buildup. It shortens the lifetime of electrical appliances in the house and negatively affects the operation of washer and dishwasher machines.Look at our page and find the right one for you Best Water Softener Reviews – Comparison of the Top Rated Systems. Limescale also worsens the look of surfaces such as glassware and silverware, resulting in additional expenses on the purchase of cleaning products.
Water softeners eliminate the minerals, therefore prevent the development of limescale. As a result, the softener offers a longer life of home appliances, including dishwashers, washing machines, water heaters, less use of household and personal cleaning products.
Skin And Healthcare
The exposure of calcium, magnesium, and other dissolved minerals in the water causes the skin to dry out. The high mineral content in unsoftened water makes it hard for other substances to absorb, resulting in more usage of the soap during showering. The hard water also makes it more challenging to rinse the soap out of the body. A layer of soap sticks to the body even if it cannot be seen, resulting in irritated, clogged, and dry skin.
Water softeners eliminate nearly all of the calcium and magnesium from the water and serve a lot of benefits to the households. The softeners prevent the development of harmful limescale in the house. This buildup causes the damage to a lot of electrical appliances, ruining the surface of glassware and silverware, and results in additional expenses of the cleaning products. Water softeners are also proven to reduce heating and energy costs drastically. The softeners prevent the exposure of calcium, magnesium, and other dissolved minerals in the water supply for negatively affecting the skin. Hard water is known for its irritating, pore clogging and drying effect on the body that cannot be fixed by using cosmetics. Consequently, water softeners do work and provide various benefits to the households and commercial premises and even reduce the utility costs.
