1&period; Hard water
1&period;1 What is hard water&quest;

When water is referred to as 'hard' this simply means&comma; that it contains more minerals than ordinary water&period; These are especially the minerals calcium and magnesium&period; The degree of hardness of the water increases&comma; when more calcium and magnesium dissolves&period;
Magnesium and calcium are positively charged ions&period; Because of their presence&comma; other positively charged ions will dissolve less easily in hard water than in water that does not contain calcium and magnesium&period;
This is the cause of the fact that soap doesn't really dissolve in hard water&period;

1&period;2 Which industries attach value to hardness of water&quest;

In many industrial applications&comma; such as the drinking water preparation&comma; in breweries and in sodas&comma; but also for cooling- and boiler feed water the hardness of the water is very important&period;
2&period; Water softening
2&period;1 What is water softening&quest;

When water contains a significant amount of calcium and magnesium&comma; it is called hard water&period; Hard water is known to clog pipes and to complicate soap and detergent dissolving in water&period;
Water softening is a technique that serves the removal of the ions that cause the water to be hard&comma; in most cases calcium and magnesium ions&period; Iron ions may also be removed during softening&period;
The best way to soften water is to use a water softener unit and connect it directly to the water supply&period;

2&period;2 What is a water softener&quest;

A water softener is a unit that is used to soften water&comma; by removing the minerals that cause the water to be hard&period;

2&period;3 Why is water softening applied&quest;

Water softening is an important process&comma; because the hardness of water in households and companies is reduced during this process&period;
When water is hard&comma; it can clog pipes and soap will dissolve in it less easily&period; Water softening can prevent these negative effects&period;
Hard water causes a higher risk of lime scale deposits in household water systems&period; Due to this lime scale build-up&comma; pipes are blocked and the efficiency of hot boilers and tanks is reduced&period; This increases the cost of domestic water heating by about fifteen to twenty percent&period;
Another negative effect of lime scale is that it has damaging effects on household machinery&comma; such as laundry machines&period;
Water softening means expanding the life span of household machine&comma; such as laundry machines&comma; and the life span of pipelines&period; It also contributes to the improved working&comma; and longer lifespan of solar heating systems&comma; air conditioning units and many other water-based applications&period;

2&period;4 What does a water softener do&quest;

Water softeners are specific ion exchangers that are designed to remove ions&comma; which are positively charged&period;
Softeners mainly remove calcium &lpar;Ca2&plus;&rpar; and magnesium &lpar;Mg2&plus;&rpar; ions&period; Calcium and magnesium are often referred to as 'hardness minerals'&period;
Softeners are sometimes even applied to remove iron&period; The softening devices are able to remove up to five milligrams per litre &lpar;5 mg&sol;L&rpar; of dissolved iron&period;
Softeners can operate automatic&comma; semi-automatic&comma; or manual&period; Each type is rated on the amount of hardness it can remove before regeneration is necessary&period;

A water softener collects hardness minerals within its conditioning tank and from time to time flushes them away to drain&period;
Ion exchangers are often used for water softening&period; When an ion exchanger is applied for water softening&comma; it will replace the calcium and magnesium ions in the water with other ions&comma; for instance sodium or potassium&period; The exchanger ions are added to the ion exchanger reservoir as sodium and potassium salts &lpar;NaCl and KCl&rpar;&period;

2&period;5 How long does a water softener last&quest;

A good water softener will last many years&period; Softeners that were supplied in the 1980's may still work&comma; and many need little maintenance&comma; besides filling them with salt occasionally&period;
3&period; Softening salts
3&period;1 Which types of salt are sold for application in a water softener&quest;

For water softening&comma; three types of salt are generally sold&colon;
- Rock salt
- Solar salt
- Evaporated salt

Rock salt as a mineral occurs naturally in the ground&period; It is obtained from underground salt deposits by traditional mining methods&period; It contains between ninety-eight and ninety-nine percent sodium chloride&period; It has a water insolubility level of about 0&period;5-1&period;5&percnt;&comma; being mainly calcium sulphate&period; Its most important component is calcium sulphate&period; 
Solar salt as a natural product is obtained mainly through evaporation of seawater&period; It contains 85&percnt; sodium chloride&period; It has a water insolubility level of less than 0&period;03&percnt;&period; It is usually sold in crystal form&period; Sometimes it is also sold in pellets&period;
Evaporated salt is obtained through mining underground salt deposits of dissolving salt&period; The moisture is then evaporated&comma; using energy from natural gas or coal&period; Evaporated salt contains between 99&period;6 and 99&period;99&percnt; sodium chloride&period;

3&period;2 Should we use rock salt&comma; evaporated salt or solar salt in a water softener&quest;

Rock salt contains a lot of matter that is not water-soluble&period; As a result&comma; the softening reservoirs have to be cleaned much more regularly&comma; when rock salt is used&period; Rock salt is cheaper than evaporated salt and solar salt&comma; but reservoir cleaning may take up a lot of your time and energy&period;

Solar salt contains a bit more water-insoluble matter than evaporated salt&period; When one makes a decision about which salt to use&comma; consideration should be given to how much salt is used&comma; how often the softener needs cleanout&comma; and the softener design&period; If salt usage is low&comma; the products could be used alternately&period;
If salt usage is high&comma; insoluble salts will build up faster when using solar salt&period; Additionally&comma; the reservoir will need more frequent cleaning&period; In that case evaporated salt is recommended&period;

3&period;3 Is it harmful to mix different kinds of salt in a water softener&quest; 

It is generally not harmful to mix salts in a water softener&comma; but there are types of softeners that are designed for specific water softening products&period; When using alternative products&comma; these softeners will not function well&period;
Mixing evaporated salt with rock salt is not recommended&comma; as this could clog the softening reservoir&period; It is recommended that you allow your unit to go empty of one type of salt before adding another to avoid the occurrence of any problems&period; 

3&period;4 How often should one add salt to a softener&quest;

Salt is usually added to the reservoir during regeneration of the softener&period; The more often a softener is regenerated&comma; the more often salt needs to be added&period;
Usually water softeners are checked once a month&period; To guarantee a satisfactory production of soft water&comma; the salt level should be kept at least half-full at all times&period;

3&period;5 How come water sometimes does not become softer when salt is added&quest;

Before salt starts working in a water softener it needs a little residence time within the reservoir&comma; since the salt is dissolving slowly&period; When one immediately starts regeneration after adding salt to the reservoir&comma; the water softener may not work according to standards&period;
When the water softening does not take place it could also indicate softener malfunction&comma; or a problem with the salt that is applied&period;
4&period; Softening costs
4&period;1 How much does a water softener cost&quest;

Some softeners are more efficient than others and as a result the prizes may differ&period; There are time operated softeners and water meter-controlled softeners available&period; The water meter-controlled units produce the softest water per pound of salt&period;
Some softeners work on electricity&comma; but some more recent water softeners use waterpower&period; Costs of a water softener greatly depend upon the type of water softener and the type of energy that is used&comma; but also upon the hardness of the water that needs softening and the water use&period; When the water is very hard and it is used heavily&comma; the costs of softening will rise&period;

Generally the costs of a water softener can vary between € 0&comma;20 and € 0&comma;40 a day&period;
The costs of water softeners are usually far outweighed by the benefits and cost savings obtained&comma; through using softened water&period;

4&period;2 How much does a water softener cost during operation&quest;

The running cost is merely the cost of salt&period; This is likely to be around € 1&comma;95 per person in the household in a month&period;
5&period; Softening drinking water
5&period;1 Do water-producing companies always produce softened water&quest;

Although water-producing companies do have the opportunity to produce softened water&comma; they will not always do so&period; A water producing company only has to add a water softener in its water purification system&comma; to produce softened water cheaply&period;
But than consumers would not be able to have the choice to drink un-softened water&period;
Hard water problems are most likely to occur when water is heated&period; As a result&comma; hard water causes few problems to the water supplying companies&comma; especially when only cold water runs through their pipes&period;

5&period;2 Is softened water safe to drink&quest;

Softened water still contains all the natural minerals that we need&period; It is only deprived off its calcium and magnesium contents&comma; and some sodium is added during the softening process&period; That is why in most cases&comma; softened water is perfectly safe to drink&period; It is advisable that softened water contains only up to 300mg&sol;L of sodium&period;
In areas with very high hardness the softened water must not be used for the preparation of baby-milk&comma; due to the high sodium contant after the softening process has been carried out&period;

5&period;3 Can salt from softening installations enter drinking water&quest;

Salt does not have the opportunity to enter drinking water through softening installations&period;
The only purpose of salt in a water softener is to regenerate the resin beads that take the hardness out of water&period;
5&period;4 How much sodium does one absorb from softened water&quest;

The sodium uptake through softened water depends on the hardness of the water&period; Averagely&comma; less than 3&percnt; sodium uptake comes from drinking softened water&period;
Estimates say that a person consumes about two to three teaspoons of salt a day&comma; from various sources&period; Assuming a daily intake of five grams of sodium through food and the consumption of three quarts of water&comma; the contribution of sodium &lpar;Na&plus;&rpar; in the water from the home water softening process&comma; is minimal compared to the total daily intake of many sodium-rich foods&period;

5&period;5 Will softening drinking water deprive it of essential minerals&quest;

Softening will not deprive water of its essential minerals&period; Softening only deprives drinking water of minerals that cause the water to be hard&comma; such as calcium&comma; magnesium and iron&period;
6&period; Softeners maintenance
6&period;1 When does a softener resin need replacement&quest;

When the water does not become soft enough&comma; one should first consider problems with the salt that is used&comma; or mechanical malfunctions of softener components&period; When these elements are not the cause of the unsatisfactory water softening&comma; it may be time to replace the softener resin&comma; or perhaps even the entire softener&period;
Through experience we know that most softener resins and ion exchanger resins last about twenty to twenty-five years&period;

6&period;2 Does a softener brine tank need cleaning&quest;

Usually it is not necessary to clean out a brine tank&comma; unless the salt product being used is high in water-insoluble matter&comma; or there is a serious malfunction of some sort&period;
If there is a build-up of insoluble matter in the resin&comma; the reservoir should be cleaned out to prevent softener malfunction&period;

6&period;3 What is 'mushing' and why should we avoid it&quest;

When loosely compacted salt pellets or cube-style salt is used in a resin&comma; it may form tiny crystals of evaporated salt&comma; which are similar to table salt&period; These crystals may bond&comma; creating a thick mass in the brine tank&period; This phenomenon&comma; commonly known as 'mushing'&comma; may interrupt brine production&period; Brine production is the most important element for refreshing of the resin beads in a water softener&period; Without brine production&comma; a water softener is not able produce soft water&period;
7&period; Softener operational questions
7&period;1 Can brine from softeners damage a septic tank&quest;

The Water Quality Association has performed studies on this subject&period; These studies have indicated that a properly placed septic tank that works adequately cannot be damaged by brine that is discharged from a water softener&period; And softened water can sometimes even help reduce the amount of detergents discharged into a septic tank&period;

7&period;2 Can a water softener be used with lead pipes&quest;

Lead pipe systems have to be replaced&comma; before softened water can flow through them&period; Although lead pipe systems in hard water areas may not cause a problem&comma; it is advisable to replace them anyway&period; When naturally or artificially softened water ends up in these lead pipe systems&comma; it may cause the pickup of lead&period;
8&period; Softening in households
8&period;1 Can a water softener be taken along during moving&quest;

With modern water softeners&comma; it is very possible to take them along during moving&period; Installation techniques involve quick fitting connections&comma; similar to those used for laundry machines&period;
All that has to be done is closing off the inlet and outlet valves of the softener and open up the bypass valve&comma; allowing hard water to flow to the storage tank and household taps&period; After that the softener can be disconnected&comma; moved to its new location and placed there&period;

8&period;2 Can waste from a water softener be discharged directly in the garden&quest;

As brine alters the osmotic pressure that plants rely upon to regulate water needs&comma; direct discharge of either sodium or potassium chloride brine should be avoided&period;

8&period;3 Is softened water any help for dry skin conditions&quest;

There are cases to be noted&comma; in which people with dry skin conditions have benefited from water softening&comma; because soft water is kinder to the hair and skin&period;
