Water softener system is primarily used to remove minerals from the water, particularly the magnesium and calcium. Hard water that contains a number of mineral ions makes it difficult for the soap to dissolve and may clog water pipes, as well as cause lime scale on the pipes. Today, there are various water softening system available that will help remove these mineral ions from the water.
Ion Exchange Softeners
Ion exchange softeners make use of salts for the removal of the mineral irons from the water. The sodium ions present in salt are coated in an exchange medium. When calcium or magnesium ions are present, they switch places with the sodium ions and are ultimately removed from the water. This type of water softening system helps prolong the life span of many water-based home appliances, such as the dishwasher, because you will need to use less amounts of soap and detergent.
The water softening system will also reduce water spotting, thereby producing much cleaner items. However, it is important to note that this system is not recommended for drinking water and watering the plants and the lawn due to its sodium content; making it dangerous for those who need to restrict their sodium intake. If there are too many calcium or magnesium ions inside the ion exchange chamber, it will cease working; therefore, you need to remove the ions for it to start working again.
Magnetic softening water softener system makes use of magnets and carbonated salts to take out mineral ions. Although it is not yet proven whether the magnets can actually take out minerals from the hard water, but it prevents lime scale from accumulating on the pipes. The precipitate minerals are carried along in the water and can be collected on the filter.
Water softener system that utilizes reverse osmosis uses semi permeable membranes that remove ions and impurities form the water. Pressure is used to push the hard water through these membranes to block minerals and impurities. The major advantage of this water softening system is that it actually removes approximately 98% of the mineral ions in the water; removing calcium, magnesium, heavy metals, and other solids. However, it also removes the minerals that are essential for humans, cooking, and plants. Furthermore, only 5 to 15% of the water runs through; thus, the rest of the water will go through waste. It is also the slowest way to soften water and the most expensive among the types of systems.
Salt-free water softeners make use of nanotechnology for the removal of the mineral ions from the water. The atoms are arranged in a certain manner which creates active sites to bind the minerals. The newly bound form of minerals cannot attach to any surface, preventing the formation of the lime scale. This system is highly recommended for those who need to restrict their salt intake. Compared to ion exchange softeners, you won’t need to use much soap or detergent when washing and the system prevents the formation of the lime scale. This is also an eco-friendly method of softening water. However, if you water the hardness level which is above 75 grains per gallon then the salt-free system may not be able to effectively soften the water.
