Waters hardness level depends on the number of minerals like calcium and magnesium is present. What does this look like? You will see white chalky mineral stains on your water fixtures, as well as spots on your glasses after washing them. You may also notice less water pressure as the calcium in the water causes scale build up in your plumbing. The most common way to treat hard water is with a Water Softener. This is a water filtration system that filters out the hard water minerals in your water.
Was the water travels into the filter, it passes through a bed of resin that traps the calcium and magnesium, which are then replaced with sodium ions. The process is called ion exchange. A water softener needs salt to function properly. A separate storage tank is needed to carry water softener salt.
This is called the brine tank. There is a regeneration process in which the water from the brine tank carrying the sodium ions , travels into the water softener tank, cleaning the reason, and flushing out the hard minerals out of the system.

The most important one is it will prevent scale build-ups in your fixtures and plumbing.
Your water pressure will be better and your dishes cleaner. This reservoir is where the mechanism draws the brine for the regular flushing of the ion exchange beads. Most softeners will have either a manual mechanism to initiate a flushing cycle, or an electronic timer, flow meter, or sensor-type system that will do the same thing.
Ion exchange is the most common technology used in household applications. While maintenance, ongoing operating costs and increased sodium in the water which can be an issue for those who must observe a reduced sodium diet are drawbacks, ion exchange is a simple, effective and safe solution to hard water woes. Unlike conventional water softeners, TAC systems do not require backwash or regeneration with salt so they are regarded as being more environmentally friendly. We offer a line of whole house TAC hard water conditioners.
Polyphosphate: Generally, polyphosphate feeders are effective in low volume, cold water applications. The polyphosphate dissolves into the water and coats the iron, calcium and magnesium in it, making it impossible for these agents to precipitate out of the water and create the problems associated with hard water.
Polyphosphate crystals are placed within a housing and as water flows through it, the crystals dissolve. What is Hard Water? How do I know if I have hard water? These are not signs of poor housekeeping, but are rather signs of hard water from the municipal water supply.
These ions do not pose any health threat, but they can engage in reactions that leave insoluble mineral deposits. These deposits can make hard water unsuitable for many uses, and so a variety of means have been developed to "soften" hard water; i. Mineral deposits are formed by ionic reactions resulting in the formation of an insoluble precipitate. This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes.
In small quantities, these deposits are not harmful, but they may be frustrating to try to clean. As these deposits build up, however, they reduce the efficiency of heat transfer, so food may not cook as evenly or quickly in pans with large scale deposits.
More serious is the situation in which industrial-sized water boilers become coated with scale: the cost in heat-transfer efficiency can have a dramatic effect on your power bill! Furthermore, scale can accumulate on the inside of appliances, such as dishwashers, and pipes. Ion-exchange reactions, similar to those you performed in this experiment, which result in the formation of an insoluble precipitate, are the basis of this process.
These solids can be collected, thus removing the scale-forming cations from the water supply. To see this process in more detail, let us consider the reaction for the precipitation of Mg OH 2.
