A water softener reduces the calcium or magnesium ion concentration in hard water. These “hardness ions” cause three major kinds of problems. The metal ions react with soaps and calcium sensitive detergents, hindering their ability to lather properly and forming an unsightly precipitate— the familiar scum or “bathtub ring”. Presence of “hardness ions” also inhibits the cleaning effect of detergent formulations. More seriously, calcium and magnesium carbonates tend to adhere to the surfaces of pipes and heat exchanger surfaces. The resulting scale build-up can restrict water flow in pipes. In boilers, the deposits act as thermal insulation that impedes the flow of heat into the water; this not only reduces heating efficiency, but allows the metal to overheat which, in a pressurized system, can lead to failure.” The presence of ions in an electrolyte can also lead to galvanic corrosion, in which one metal will preferentially corrode when in contact with another type of metal. The use of water softeners can aggravate this and cause sacrificial anodes in hot water heaters to corrode more quickly.

Conventional water-softening devices intended for household use depend on an ion-exchange resin in which “hardness” ions trade places with sodium ions that are electrostatically bound to the anionic functional groups of the polymeric resin. A class of minerals known as zeolites also exhibits ion-exchange properties; these minerals were widely used in earlier water softeners.

Water softeners are typically used when water is supplied from wells. Public water systems are also susceptible to hard water, although this is much less common.

How it works
The water to be treated passes through a bed of the resin. Negatively-charged resins absorb and bind metal ions, which are positively charged. The resins initially contain univalent sodium or potassium ions, which exchange with divalent calcium and magnesium ions in the water. This exchange eliminates precipitation and soap scum formation.

As the water passes through both kinds of resin, the hardness ions replace the sodium or potassium ions which are released into the water. The “harder” the water, the more sodium or potassium ions are released from the resin and into the water.

For people on a low-sodium diet, the increase in sodium levels (for systems releasing sodium) in the water can be significant, especially when treating very “hard” water. A paper by Kansas State University gives an example: “A person who drinks two liters (2L) of softened, extremely hard water (assume 30 gpg) will consume about 480 mg more sodium (2L x 30 gpg x 8 mg/L/gpg = 480 mg), than if unsoftened water is consumed.” This is a significant amount, as they state: “The American Heart Association (AHA) suggests that the 3 percent of the population who must follow a severe, salt-restricted diet should not consume more than 500 mg of sodium a day. AHA suggests that no more than 10 percent of this sodium intake should come from water. The EPA’s draft guideline of 20 mg/L for water protects people who are most susceptible.”

Regeneration
As these resins become converted to their Ca2+ form they gradually lose their effectiveness and must be regenerated by passing a concentrated brine solution through them. Most of the salt used for regeneration gets flushed out of the system and may be released into the soil or sewer. This process can be damaging to the environment, especially in arid regions.[citation needed] Some jurisdictions prohibit such release and require users to dispose of the spent brine at an approved site or to use a commercial service company.

Most water softener manufacturers provide metered control valves to minimize the frequency of regeneration. It is also possible on most units to adjust the amount of salt used for each regeneration. Both of these steps are recommended to minimize the impact of water softeners on the environment and conserve on salt use.

In industrial scale water softening plants, the effluent flow from re-generation process can be very significant. Under certain conditions, such as when the effluent is discharged in admixture with domestic sewage, the calcium and magnesium salts may precipitate out as hardness scale on the inside of the discharge pipe. This can build up to such an extent so as to block the pipe as happened to a major chlor-alkali plant on the south Wales coast in the 1980s.

A water filter is a device which removes impurities from water by means of a fine physical barrier, chemical process and/or biological process. Filters are used to cleanse water for irrigation, drinking water, aquariums, and swimming pools.

Now let me introduce some uses of water filters to you. There are so many kinds of water filters such as Undersink water filter ,Countertop Water filter and so on.

Water can be cleaned using a variety of different types of water filters, both for drinking and other purposes. Filtration forms a key stage in many waste water and drinking water treatment systems. In the case of drinking water, filtration tends to be carried out by the supplier prior to the water’s entry into the distribution system. Additional filtration may be carried out by consumers at their premises using any of several types of domestic water filter.

Domestic water filters are primarily used to remove chemicals and metals such as chlorine and lead. Water filters can be used for preventative health reasons in the case of harmful substances, or for reasons of aesthetics, to improve the taste, colour or odour of drinking water. Domestic water filters can be attached directly to a tap, attached to the domestic water supply before the tap, or filters can be used at the point of use or in a portable unit.

As water is contaminated in different degrees for different towns and cities, it can be called more or less healthy. But the fact that water treated by public organizations isn’t worth drinking remains. It contains chlorine, which is dangerous for health. In order to check how clean and safe your water is water test kits are used. They are convenient to use, and the results can be received quickly, so that you don’t have to attend any laboratory. You can simply test drinking water in home conditions. With using the test you can learn the levels of heavy metals and chlorine in your drinking supply. The results will show you if you need to improve your water treating methods or buy a water filter,such as Undersink water filter .

Researches have revealed that if an individual consumes faucet water without purifying it, chlorine, contained there, can lead to difficult forms of cancer. Hard water can be the reason of lime membrane and clogging and uneconomic cleaning remedies’ usage. Magnesium and calcium, the components which are blamed for water hardness, can be a reason of some negative impacts. Actually, magnesium and calcium significantly endanger plumbing and water heating systems.

If you’ve found that the water you consume is unhealthy (it contains much chlorine or hard metals) it’s a reasonable sign for you to purchase a water filtration system. Such system will catch all known contaminants from your water and thus will provide your family with healthy drinking supply.

If you’re still convinced that tap water is enough clear, purchase a water test kit and check it. No doubt, the results will surprise you, as modern treatment is not perfect. Seeing how much polluted your water is you’ll define what purifier you need and whether you need it for all your taps.
