According to statistics, 90% of water heating and plumbing equipment breaks due to hard water. Scale forms, pipelines clog, water heaters lose power, household appliances fail. High rigidity is also dangerous for people. Sand and stones form in the organs, blood vessels and the heart suffer, the skin becomes dry, and dermatitis occurs. So that there are no accidents at home, and health does not deteriorate, they produce water softening using filters.
Hardness is a property of water that depends on the content of calcium (Ca) salts in the dissolved form and, at a lower concentration, silicon (Si lat. Silicium), magnesium (Mg).
- Carbonate
- Non-carbonate
- General
Carbonate is temporary. Easily removed by boiling. It is determined by the presence of calcium bicarbonates (Calcium), magnesium in the liquid. Chemical formula— Ca(НСО3)2; Mg(HCO3)2. Forms scale in hot water pipelines, in a kettle, on water heating elements boilers, boilers.
Non-carbonate constant. Boiling is not removed. It is due to the presence of salts, which differ in properties from carbonate. Basically, these are chlorides (CaCl2, MgCl2), sulfates (CaSO4, MgSO4).
Total hardness is the sum of the 1st and 2nd hardness. The final indicator of the content in the liquid of all ions and compounds of magnesium, calcium present. Since 2014, updated standards have appeared, according to which this parameter is measured in degrees of hardness - ° W \u003d 1 meq per liter. According to the total hardness of water:
- Rigid - more than 10°F
- Medium hardness - 2-10
- Soft - up to 2
In Europe, the concentration rate is 2.5; in the Russian Federation - 7.
AT well water"hard" chemical compounds come from soluble rocks, which consist of dolomite, lime, gypsum. If the region is rich in these minerals, they will definitely be in the water. Need water softener filter.
Why soften domestic water |
"Hard" salts gradually accumulate in the body. Vessels are clogged. The heart suffers. Stones appear in the kidneys and other organs and body cavities. Urolithiasis occurs. The use of water of increased hardness causes serious harm to health. Besides:
- Scale formed on heaters and inside heating radiators reduces heat transfer
- Detergents give little foam. Consumption household chemicals increased by 60%
- Dishes take longer to cook. Meat stays tough after cooking
- 1 mm scale increases power consumption by 10%
- Leads to overheating of heating elements. Causes 90% of water heater failures
Hard water worsens appearance. The skin dries up, peels off. Dermatitis, acne, redness appear. Hair is not washed, looks untidy, becomes naughty. Plaque forms on the teeth.
Hard water is dangerous for newborns. Increases the likelihood of eczema and atopic dermatitis with constant use, bathing. Symptoms appear as early as 3 months. Eczema causes autoimmune allergies and further to food allergies, asthma.
The best protection - buy and install water softener filter. Water treatment and purification devices soften well, make domestic water suitable for drinking, household use.
Strong magnets are also used in water treatment. The liquid is passed through a powerful magnetic field. As a result, water changes physical characteristics, dissolved impurities lose their ability to form salts, and, consequently, scale. In addition, magnetized water destroys and removes already deposited scale layers. The technology is effective at a low content of calcium, silicon, magnesium ions.
Fluid is affected electric field high charge using special membranes. Hardness ions and some other substances are removed. The technology is used for desalination sea water in industrial volumes, in the production of table salt and for the preparation of water in thermal power plants.
Made with reagents. use slaked lime Ca(OH)2, sodium orthophosphate Na3PO4 or soda ash Na2CO3. When interacting with the reagent, hardness salts take on an insoluble form, settle to the bottom and are easily filtered out. This technology is justified when cleaning large volumes of liquid. When applied, a number of specific technological problems arise. You need the exact dosage of the chemical reagent.
The technology refers to reagent softening methods. For water treatment, granular filter media are used, mainly ion-exchange resins, which are loaded into water softener filters. When interacting with resin granules, ions of “hard” compounds, as well as iron and manganese, are trapped from the liquid. Depending on the type of filter material, sodium, potassium or hydrogen ions are formed during the ion exchange process. With a well-chosen load, it is possible to reduce the hardness to 0.1-0.01 ° W even with ultra-high mineralization.
Advantages of ion exchange filters:
- Price 20-50% lower
- Universal. Suitable for cottages country houses, urban apartments. They are placed on wells, wells, cut into urban water supply pipelines
- Productive. Removes hardness, iron, excess minerals, manganese, organic compounds and other contaminants in one can
- Eliminate ultra-high concentrations of iron - up to 30 mg
Over time, resins become clogged with contaminants held by chemical bonds and stop softening the water. However, the ion exchange reaction is reversible. If you pass a solution of table salt through the resin, the impurities will separate, and the sodium contained in the salt will fill the voids formed. The separated contaminants are washed into the drain. The renewed resin cleans and softens the water again.
To some, the phrase "hard water" will seem like a literary oxymoron, but there are many people who are familiar with this quality of water firsthand. How to determine the degree of hardness and why soften water - we will tell in this article.
Hard water is the reason for the formation of salt deposits, kidney stones, cardiovascular diseases. 80% of diseases a person drinks with water. 90% of failures of water heaters and other equipment working with water are caused by high severity.
What is the purpose of the water softening process?
Water hardness is a combination of its physical and chemical properties associated with the content of dissolved salts of alkaline earth metals. First of all, calcium and magnesium are hardness salts. AT natural environment they govern various chemical processes. The hardness of water is mainly influenced by its deposit. Rivers and lakes are replenished from underground sources flowing in limestone layers and enrich the water passing through them with hardness salts. AT surface waters contains significantly less calcium and magnesium than in the deep. The hardness of water in natural springs reaches its maximum in winter, and its minimum in spring, thanks to melting snow.
There are three types of water hardness:
- General. This is the total concentration of magnesium and calcium ions.
- Carbonate. Its second name is temporary, since the indicators depend on the content of calcium and magnesium carbonates and bicarbonates in water, which are almost completely eliminated by boiling.
- Non-carbonate, on the contrary, is a constant value, because it is due to the presence of magnesium and calcium salts, which are not affected by temperature changes.
In the SI system, water hardness is measured in moles per cubic meter -mol/m³, but milligram equivalents per liter are also used in practice -mg-eq/l. According to SanPiN standards, rigidity drinking water should be no more than 7 mg-eq / l. Required water hardness for beer production -up to 4 mg-eq/l, soft drinks -0.7 mg-eq/l.
Excessively hard water is one of the reasons for the formation of kidney stones, since calcium and magnesium bicarbonates make it difficult for the stomach and intestines to work. The so-called salt deposits in the joints can also be the result of drinking hard water. The hardness salts contained in it actively interact with soaps, shampoos, balms and other similar products, forming a precipitate and reducing their effectiveness. Due to the destruction of the natural fatty protection, the pores on the human skin are clogged with neoplasms, making it difficult to breathe. This can lead to dryness, acne, dandruff, as well as breakage and hair loss. Hard water also does not affect cooking. in the best way, destroying the beneficial substances contained in the ingredients.
Hard water significantly shortens the service life household appliances: dishwashers, boilers, kettles, etc. Due to the crystallization of salt, scale is formed, which subsequently leads to corrosion and breakage. As in the case of shampoos, when washing in hard water, part of the “forces” of the powder is directed to neutralize its effect, but here, in addition to the banal overspending detergents, the chances of getting stained or streaked laundry increase. They also arise due to scale formed on the "insides" of the washing machine.
In urban areas, hard water is almost never found now, but in private sectors and rural areas the situation is different. Usually their inhabitants use water from a well or artesian well, which receive saturated with calcium and magnesium ground water. In addition, along with hardness salts, others can also get there. harmful substances. For this it is enough heavy rain and a nearby garbage dump.
How easy it is to understand water softening - this is a decrease in the concentration of hardness salts in it. The simplest version of this process is thermal (it is also simple boiling). As already mentioned above, when this process calcium bicarbonate breaks down into insoluble calcium carbonate, which precipitates, and carbon dioxide. The concentration of calcium sulfate also decreases somewhat. This method is considered the simplest, but its performance leaves much to be desired. Is there some more chemical method when reagents are added to water that turn soluble compounds into insoluble ones. The main disadvantage is that you still can’t drink such a liquid. Other methods require special equipment.
Water softening equipment
In addition to plaque on the heating elements of household appliances and stains on washed linen, a sign of hard water is poorly foaming soaps and powders, meat that is hard even after long cooking, the absence of the usual aroma of tea and coffee, as well as the bitter taste of the water itself. In addition, water hardness can be determined using special test strips or a TDS meter measuring the electrical conductivity of a liquid. However, before purchasing a filter for softening water, it is recommended to send it to a laboratory for analysis, so that experts can make the most accurate “diagnosis”. For example, a flow filter for water softening will be relevant only for liquids without a critical iron content, and in severe cases it is better to use a main one.
What installations are used for water softening? Experts distinguish the following categories of filters:
- Membrane. Eliminate up to 98% of impurities, making the water actually distilled. However, in order for the quality of their work not to decrease, it is necessary to maintain a pressure of at least 3–4 atmospheres in the water supply system. Such a device is quite expensive, but it also has a long service life.
- Polyphosphate. They are a flask with crystals of polyphosphate salt. The water passing through them is saturated with sodium polyphosphate. Usually attached in front of household equipment. Polyphosphate filters are inexpensive, but they need to be changed every six months. It is not recommended to drink water softened with their help.
- Magnetic. Thanks to them, a constant magnetic field acts on the water, which changes the structure of hardness salts. The molecules cease to combine when heated and do not form a precipitate, and also destroy the already existing scale. The salt concentration remains the same, so that such devices are mainly suitable for pipes and pumping equipment. Depending on the variety, magnetic filters can operate from 5 to 25 years without the need for maintenance.
- Electromagnetic. Work on the basis of radiation electromagnetic waves required frequency. They require a network connection, but do not consume a lot of energy. Compatible with any other water softening systems. Excess salts are then removed through the sump into the sewer. As well as magnetic ones, they additionally destroy scale, but they cost an order of magnitude more expensive.
- Ion exchange filters for water softening. Their clear advantage is high performance and durability of the filter element. They are a column or cabinet type filter, inside of which there is an ion exchange resin. As with magnetic filters, they can only be used to clean cold water. The filtration process consists in replacing calcium and magnesium ions with sodium ions, which do not harm the human body and household appliances.
Despite the fact that after the ion-exchange method of softening water can be drunk, it is considered reagent, the rest are classified as non-reagent.
To de-iron does not mean to soften
The term "hard water" is not synonymous with "iron water". Fresh water also contains iron, which enters wells and boreholes from collapsing rocks, and into pipes from aging and corroded cast iron and steel water pipelines. It is not difficult to determine water supersaturated with iron by eye - it has a characteristic metallic smell and a yellowish-turbid tint. With such indicators, white things also become yellowish after washing, and brown spots appear on plumbing.
In our country, the allowable amount of iron in water should not exceed 0.3 mg-eq / l. The recommended total iron intake for an adult is 25 milligrams per day.
"Overdose" can lead to urolithiasis, intestinal disorders, gallbladder diseases and dental problems, as well as dermatitis and the development of allergies. Therefore, there is no point in purchasing water softening devices, while neglecting iron removal equipment. It is also different, both chemical, when iron is destroyed by reagents, and mechanical, when iron is decomposed using aeration, coagulation, and the ion-exchange method described above. Moreover, there are “two in one” installations that simultaneously work both for water softening and iron removal. They save space in the house, the owner's budget and his time in equal measure.
Technology is advancing rapidly, and maybe someday all the water on Earth will be exceptionally clean. But until this happens, the presence of a water filtration system is an urgent need, because human health directly depends on it. At the same time, you don’t want to spend a lot of money on inefficient equipment, so the choice of a filter for iron removal and water softening should be approached carefully.
Station for water purification from hardness salts
The indicator "hardness of water" displays the quantitative content of alkaline earth metals in it. Due to the fact that the main contribution is made by calcium and magnesium, the remaining alkaline earth metal ions are neglected. The term itself has a household origin: a fabric washed in water with a high content of calcium and magnesium becomes hard to the touch. Water hardness is divided into carbonate (temporary) and non-carbonate (permanent). Temporary - due to calcium and magnesium bicarbonates, permanent - mainly chlorides and sulfates. Temporary hardness is reduced by boiling due to the formation of insoluble carbonates. Ohigh water hardness, as well as an excess of iron, can be judged by the traces left in the form of scaleon heating elementsgray deposits on drying surfaces, dry tight skin, hard linen after washing.The process of removing hardness ions from water is called softening. Depending on the purpose of the water, the requirements for water hardness are different. For drinking water, SanPiN 2.1.4.1074-01 sets a maximum concentration of 7 mg-eq / l, and according to the WHO recommendation, calcium in drinking water should contain 20-80 mg / l, magnesium - 10-30 mg / l, which corresponds to hardness 1, 8-6.5 mg-eq/l. For household appliances(washing machines, dishwashers, boilers), manufacturers recommend using water with a hardness of no more than 1.5 meq/l. The highest requirements for hardness are imposed on water for, the hardness of the prepared water should not exceed 5 µg-eq / l.
Water softening - terms
- Thermal . When water is heated, calcium and magnesium bicarbonates turn into insoluble carbonates and settle on the walls of a water heater, kettle, etc. This method applicable when there is a small need for water, for example, for giving, and provided that most of the hardness is temporary (hydrocarbonate). The disadvantage of this method is also the difficulty of cleaning the heating surface from scale.
- Reagent softening . The method is based on the introduction of slaked lime Ca (OH) 2 - liming, or slaked lime Ca (OH) 2 and soda Na2CO3 - soda-liming into water, to convert hardness salts into insoluble carbonates, with further precipitation or clarification. Additionally, coagulants and flocculants can be introduced. The method is used in industry for large volumes of water consumption with high carbonate hardness. When liming and soda-liming are used, alkalinity decreases simultaneously with hardness, during settling and clarification, suspended particles, including colloids, are removed, they can also be sorbed on sediment flakes organic pollution. The disadvantages of this method are the high consumption of reagents, the need for a reagent economy, the large dimensions of the equipment when using sedimentation tanks, the formation of sludge that is difficult to dispose of. This method is not applicable to the preparation of drinking water, since softened water has a high pH value pH.
- Ion exchange (Na-cationization) . The most common and accessible method, used for both industrial, and for private water treatment systems . The method is based on the replacement of calcium and magnesium ions with sodium ions when water passes through a strongly acidic cation exchanger in the Na-form. During the cleaning process, the ion-exchange resource of the load is exhausted and its regeneration is required. Restoration is carried out with a 6-10% solution of sodium chloride (common salt), during regeneration, calcium and magnesium ions are again replaced by sodium ions, and the load is ready for further work. The frequency of regeneration is determined by the hardness of the source water.
- Reverse osmosis and nanofiltration . These methods belong to membrane cleaning methods. At the core reverse osmosis and nanofiltration is based on the principle of filtration through a semi-permeable membrane. The cleaning process also removes other ions and contaminants, and reduces the overall mineralization of water. Installations are made both industrial, and household scale. Settings reverse osmosis indispensable for the purification of very hard water with an excess of salinity or sodium. The disadvantages of the method include high energy consumption compared to ion exchange.
Separately, you can specify the method of binding hardness salts with polyphosphate reagents, magnetic and pulsed processing, changes in the structure of hardness salts - all these methods do not remove calcium and magnesium ions from water, but only prevent the formation of scale.
Water treatment plants series - Water softening station 
Purpose:
Water softening- extraction of calcium Ca2+ and magnesium Mg2+ ions from water, which determine its hardness. Hardness salts cause scale formation on heating elements and internal surfaces of pipes, increased consumption of detergents, and cloudy water.
Description:
The water softening station consists of a fiberglass body with an internal polyethylene liner, an Autotrol automatic control valve (Pentair Water, USA), a drainage distribution system, an ion exchange load, a gravel bed and a salt tank for regeneration.
Operating principle:
Water softening occurs by the mechanism of ion exchange, while calcium and magnesium ions are replaced by an equivalent amount of sodium ions. When the resource of the ion-exchange resin is exhausted, it is necessary to regenerate it with an 8-10% solution of common salt (NaCl). For this, special tableted salt is used, which is not subject to caking. The solution is prepared in a salt tank, the tank is filled with water automatically.In charge service personnel includes salt filling and control of its level.
"Lewatit" S1567 (Germany) is a strongly acidic helium cation exchanger in sodium form based on a styrene-divinylbenzene copolymer. Monodisperse granules have extraordinary chemical and mechanical stability and high osmotic resistance. The working exchange capacity is higher than that of most resins (taking into account aging) - 1200-1400 meq/l of resin is taken. Regeneration - with a solution of common salt (NaCl).
Source water requirements:
- General hardness - up to 15 mg-eq / l, total salt content is not more than 1000 mg / l;
- Lack of ferric iron in water;
- The maximum content of dissolved iron in water is not more than 0.5 mg/l;
- Permanganate oxidizability - no more than 3.0 mg O2/l;
- Color - no more than 30 degrees;
- Absence of suspensions, oil products, hydrogen sulfide and sulfides;
- Content of free active chlorine - no more than 1 mg/l.
Specifications:
- Water pressure at the filter inlet: minimum - 2.5 atm, maximum - 6.0 atm.;
- Pump equipment must provide a water flow rate not less than required for flushing (depending on the filter model);
- The installation installation room must have an inlet and a drainage line;
- Availability of stabilized power supply 220V (±5%), ~50Hz;
- Room temperature: from +5 to +35˚С, humidity - no more than 70%, temperature of treated water from +2 to +45˚С.
Water softening stations in the cottage
"and" Chemical reagent methods of water softening" section "Water" and subsection "" we touched on the topic of combating hardness salts and scale. In previous articles, we examined the actual definition of the word "water softening" and considered that there are several ways of softening - physical, chemical, extrasensory.And also touched upon such reagent methods of water softening as ion exchange and the dosage of antiscalants (antiscale formers).In this article we offer you two subsections - a little about extrasensory methods and a little more about physical ways water softening.
Psychic and physical methods of water softening are not fully understood and studied. This is probably why very often the psychic way of dealing with hard water is confused with the physical way of dealing. And, accordingly, they lose money, time and faith in people. Both for the purchase of psychic gadgets, and for the repair of equipment that they did not protect from scale. By the way, for a good understanding of the article, we recommend that you first study the materials of the articles "Hard water" and "", where the main definitions used in this article are given (such as water softening, scale, hardness, hardness salts, etc.)
Psychic methods of water softening.
So, psychic methods are easily confused with physical ones. About the same as the ganzfeld effect with magic. For example, water treatment magnetic field. This and quality way dealing with scale, and a useless extrasensory way of cleaning and structuring water.
The difference between physical and extrasensory methods is very simple - if a thing costs a little money (up to 100 USD on average), and it is promised that it will fulfill a lot of tasks (such as: it will purify water from all substances, remove scale, heal and give youth, structures, accelerates the growth of plants and hair, removes spoilage, etc.), then this is a psychic method of water purification. We will not dwell on extrasensory methods in detail, they are described in various sources (for example, here), since the sense from them is only a hundredth of what was promised.
By the way, in recent times there was a tendency to increase the cost of such softening structurers. So you can run into a very expensive fake, which is declared as protection against scale. However, usually devices that can really physically help with scale do not have additional structuring functions.
So, if you want to do extrasensory structuring, then you need to purchase a special device. If you need to soften the water physically, you need to purchase a special device. But not complex. Although ... As anyone likes 🙂 And we will move on to physical ways to deal with scale.
As mentioned earlier, there are several definitions of the term "water softening", depending on the stage at which the impact occurs -
- at the stage of combating the causes of water hardness or
- at the stage of dealing with the consequences of using hard water.
The previous methods - ion exchange - are aimed at combating the causes of water hardness. That is, either calcium and magnesium salts are removed from the water, which leads to the creation of soft water.
Physical methods of water softening are aimed at coping with the consequences of hard water - scale.
Accordingly, physical softening methods do not imply soft water in the first sense (water without hardness salts at all). The result of the work of physical water softening is water that has retained all its hardness salts, but does not harm pipes and boilers - that is, it does not form scale. However, hard water after physical treatment changes its properties - and, as a result, ceases to form scale. That is, it ceases to be rigid. And it becomes soft. Of course, if we were doing scientific research, we would introduce a difference in terms of "soft water", that is, water in which there are no hardness salts in principle, and "softened water", which does not form scale, but may contain hardness salts. However, these are terminological nuances that are not of interest to us. We actually physical ways of softening water.
There are such basic physical ways to deal with scale:
- Treatment of water with a magnetic field.
- Treatment of water with an electric field.
- Ultrasonic water treatment.
- Water treatment using low-current current pulses.
- Thermal softening method (normal boiling water).
And we will begin to gradually characterize the physical ways to deal with hard water. We may not cover everything at once in one article, but a series of articles will definitely include the characteristics of each of the methods. Let's start with the treatment of water with a magnetic field, since this type of physical descaler is most often confused with psychic water softening.
Treatment of water with a magnetic field is a complex and controversial issue. Without going into details, we can say that effective physical softening of water with the help of a magnetic field is possible only when it is possible to simultaneously take into account a huge number of factors. This is:
- magnetic field strength,
- water flow rate,
- water composition:
- ionic (including the presence of iron and aluminum ions that impair the physical treatment of water),
- molecular (including large organic molecules, especially those with the ability to form complexes),
- mechanical impurities (including rust),
- ratio of para- and diamagnetic components,
- dissolved oxygen and other gases
- the presence of non-equilibrium systems, etc.
- water temperature during and after treatment,
- processing time,
- Atmosphere pressure,
- water pressure,
- etc.
All these and many other factors affect the efficiency of magnetic water treatment. Thus, an insignificant change in the composition of water should be compensated by changes in the specified parameters (for example, water velocity and magnetic field intensity). All changes must be monitored and responded to immediately, since the effectiveness of physical water softening using a magnetic field will change in an unknown direction.
But it is possible, and magnetic water treatment is successfully used in many boiler houses. First of all, this happens because in boiler houses the constancy of most of the listed factors is observed - both the flow of water, and the composition of water, and the water temperature, and pressure, etc.
However, this is practically NOT possible to repeat at home. And when you have a desire to buy a magnet for a pipe in order to save your house from scale, then think a lot of times, and first of all, consider whether you can organize not only the constancy of the indicators described above, but also find them optimal combination through experiments.
If not, then treating water with a magnetic field in the form of magnets is not for you, and you will not get anything except for wasting money on buying a magnet and repairing equipment and pipes. In another way, it can be said like this: the probability that a tube magnet will help you is less than 10%. That is, at home, a constant magnetic field is close to extrasensory water softening.
In order to compensate for the variability of water parameters during physical treatment, more modern methods physical softening - for example, using an electronic water softener.
Thus, do not confuse psychic water softening, limited area physical softening, and modern physical water softening.
Which will be discussed in the sequel.
Hard water is distinguished high content minerals - most often magnesium and calcium. They form deposits that subsequently clog the sewer, leave plaque on the tile, and prevent the soap from foaming normally. It does not pose a threat to life and health, but it still causes certain inconveniences. In this article, we will reveal the essence of the concept of hard water and talk about ways to soften it.
Hard water is water that contains a large number of salts of calcium and magnesium. Additionally, it may contain silicates, phosphates, chlorides and other toxic compounds. Some of them completely decompose when boiled, while others are able to remain unchanged for a long time.
Why hard water is harmful to health and household appliances
Scale in the kettle, a characteristic sediment on the walls of washing machines and other household appliances, clothes that have lost their original color brightness after washing - gives a modern person a lot of inconvenience, so he seeks to soften it. The skin, hair, internal organs do not like such a liquid - the kidneys and liver are especially affected.
Increased hardness of water reduces the taste and digestibility of food, can cause the development of urolithiasis, problems with the liver, even the heart. But it has nothing to do with the presence of worms in the body.
Optimal water hardness, how to determine the hardness of water at home
Before you begin to carry out activities aimed at softening too hard water, on your own, determine the salt content and the level of hardness of the liquid. This can be done in special services, and then checked with current standards. Don't want to go anywhere? In this case, you should be alerted by scale on internal details household appliances, a small amount of soap foam, dry skin and hair. Taste may vary, but this is not a prerequisite. 
How to soften hard water at home: 8 sure ways
The main ways to soften hard water:
- Boiling followed by settling.
- Adding to washing machine soda or lime. More modern alternative- special powder
- Softening with ammonia - just keep in mind that concentrated undiluted products are on sale (read the instructions!).
- The use of a filter jug from Aquaphor.
- Installation of coal household filter to a faucet or plumbing.
- Installation of the Aquaphor purification system - it replaces magnesium and calcium ions with sodium ions.
- Installation of a special mechanical cleaning device at the inlet of the pipeline.
- The use of a magnetic softener.
Domestic water
Soda ash and baking soda effectively neutralizes salts - water purified in this way can be used for drinking purposes. Baking soda completely harmless, does not dry the skin, so it is added to the water for washing. The calcined variety is more aggressive and gives a pronounced whitening effect, so it can be used for washing clothes.
How to soften hard water at home from a well or well
To soften water from wells and wells, the same methods are used that are used to soften ordinary tap fluid:
- thermal (boiling);
- reagent - with the addition chemical substances of different origin, which, when interacting with hardness salts, bind them;
- using filters (magnetic, membrane, ion-exchange, electromagnetic);
- folk ways.
Each option has its own characteristics, advantages and disadvantages. When choosing, be guided by the current hardness indicators, the available budget and the desired water treatment rate.
Ways to clean and soften water at home
If you want to not only soften, but also purify the water, use any of the following options:
- filter jug;
- ion exchange filter;
- membrane filter;
- magnetic filter softener;
- electromagnetic method.
Folk methods are also used - settling, saturating with silicon, partial freezing, mixing, adding a decoction of flaxseeds, herbs or peat.
Filters and their varieties
On sale you can find the following types filters:
Which is better: conventional softening or complete water filtration?
The softening filter does not always give the desired results - in some cases, complete filtration is required. The cleaning system removes elements of calcium and some salts (partially), while complete filtration allows you to get rid of all chemical impurities and change the metal composition, remove salts. At the same time, it can be accompanied by softening, mineralization. If everything is done right, tap water will have good smell and pleasant taste.
Magnetic filter or special salts: choose an alternative
Special salts give a good effect, but do not forget about the dosage for each substance. You will also have to ensure their constant availability and appropriate storage conditions - and this is extra space, additional expenses and hassle. At the same time, it is not always possible to use water softened with the help of reagents for cooking and drinking.
What is a magnetic filter? A device of two powerful magnets that create strong field- it attracts metal particles. Water when passing through such an element becomes softer. Chemicals are not used, but the effect of water charged by a magnetic field on the human body has not yet been studied either.
How to soften hard water in an aquarium at home?
Mandatory softening requires water in the aquarium. At home, stiffness can be reduced in the following ways:
- Boil, cool and pour into the aquarium.
- Distill, but remember that a deficiency of useful trace elements is harmful not only to humans, but also to fish.
- - Pour water into a container and put in the freezer. When half of the liquid is frozen, pour out the part that is not frozen, and remove the ice from the refrigerator and melt. This liquid is ideal for fish.
- Purify water using a reverse osmosis filter - it is installed in the room and connected directly to the water supply.
The most efficient and costly way reverse osmosis. It makes sense to use it for large aquariums.
Good to know
- Water softening leads to noticeable savings detergents, because in soft they foam better. It's not just about soap, it's about washing powder, toothpaste, etc.
- Electricity consumption can also be reduced, since you will be doing less laundry and cleaning.
- The life of household appliances and water pipes soft water will also noticeably prolong.
- At the same time, the use of any softening method requires certain investments, which do not always pay off.
