What are water softeners?
They convert hard water into so-called soft water. Conversion occurs by reducing the mineral content. Hard water contains mainly metals: calcium and magnesium as well as bicarbonates and sulfates. Soft water, on the other hand, is water that contains little or none of these minerals.
This process is used to reduce calcium, magnesium, and in some cases manganese and iron dissolved in hard water. A softener is a system that chemically converts hard water into soft water.
Softeners replace the calcium and magnesium in hard water with sodium. The sodium does not build up in the pipes and does not react with soap. This eliminates the effects of hard water. The principle of a softener is easy to understand. Hard water enters the water softener. It contains a layer of plastic beads, and in some cases this material is called zeolite. The layer of material inside the water softener is impregnated with sodium ions. The sodium is exchanged with the hard components of water, calcium and magnesium. When the water comes out of the softener, it is called soft water.
At some point, the plastic beads or zeolite layer are saturated with calcium and magnesium ions only. This is followed by a regeneration process in which the water is mixed with sodium-rich water to form a strong salt solution. The sodium ions in turn replace the calcium and magnesium ions, which are eventually flushed down the drain.
Common table salt is inexpensive. The sodium source for water softeners is salt or sodium chloride. Large amounts of salt are cheap. It is a good source of sodium used in water softeners. A water softener consists of several cylindrical tanks and large square containers. The tanks hold the water that has already been treated, and the containers hold the salt used in the process. The number of tanks depends on the capacity and the system itself.
For residential or commercial systems, the softening station is located at the main inlet of the domestic water system. In this type of installation, all water entering the house is already treated.
There are two basic types of water softeners. One is the single tank electric water softener. This system is not only expensive, but it also has some drawbacks. The soft water supply can be depleted because the system uses a single tank. It can also cause inconvenience because this type requires high pressure. High pressure is required at night. The noise caused by running motors is not desirable at this time.
Another type of softener is the double tank hydraulic softener. This type provides a constant supply of soft water to the house. Softening and regeneration take place alternately in both tanks. In this way, the soft water supply cannot be depleted.
Salt tanks must be refilled regularly. Most softeners do not have a salt level indicator and it is recommended to check the salt level regularly to avoid contamination of the water tanks. Softening systems also run continuously without salt, which can lead to tank contamination.
Salt-based water softening systems are not 100% effective. Only 75% of the calcium and magnesium content is removed from the water. In addition, salt-based water softeners release large amounts of lime brine into the environment.
The newly developed water softener is digital. The Soo Soft digital electronic water softener is a revolutionary innovation in water softening. It is environmentally friendly and as effective as a salt water softener.
