Polyphosphate filter operating principle. Polyphosphate filter for boiler and washing machine, benefits and harms of installation. Installation and maintenance of a polyphosphate filter

Therefore, after purchasing a polyphosphate filter and installing it, it is necessary to clean the heating elements from scale using special chemical compounds. Non-abrasive solutions, which are purchased along with flushing liquids and connected to the heat exchanger, are suitable as cleaning agents for a water heater or boiler. Under the influence of high temperatures, the reagent begins to act and has a destructive effect on scale. Afterwards, the liquid must be drained, the device and heat exchanger must be washed, and the structure must be disconnected from the heater. Afterwards, the cleaning device itself is installed. The method is determined depending on the type of device with which the system is used. For example, a polyphosphate filter for a washing machine is attached to the inlet hose. The same system is also used to purify water for boilers.

Another useful property of the device is the ability to dissolve already formed layers of scale. And the softer the water, the less detergent is required for washing or washing dishes.

Why you can’t drink water after a salt filter Polyphosphate filters are designed to purify only industrial water for one simple reason - polyphosphate is a toxic substance. Moreover, at water temperatures above 40C, polyphosphates are destroyed and become ineffective.

Install this water purification device exclusively for domestic purposes! How often to change and clean a polyphosphate filter The filler consumption is quite economical - 3 grams per 1000 liters. As you use the crystals, they dissolve, so they need to be topped up periodically.

Why do you need a polyphosphate filter for a washing machine and boiler?

Manufacturers recommend completely replacing the contents of the flask if the volume of crystals in it has decreased exactly by half or if the filling of the flask has not changed over a long period. On average, as practice shows, the service life of the device is about six months.
The device is installed directly in front of the boiler and household appliances. It is necessary to make a connection in the pipe for equipment with a tap, then install a filter and then connect the equipment itself.
It can also be installed directly into the hose, from where water will flow into the boiler or washing machine. Before installation, the polyphosphate filter must be washed.

This can be done with running water under a regular water tap. This is to remove small crystals that may pass through the hose and clog the filter in the washing machine or dishwasher valve.

Polyphosphate filter for boiler and washing machine, benefits and harms of installation

If less than half of it remains, then it is best to completely replace the composition. Otherwise, the degree of protection begins to weaken.

When seeking advice from specialists, we can say that to ensure safe operation it is best to use a powder reagent. It actively fights not only scale formation, but also corrosion, which often affects heating elements.

If the affected area becomes too large, this may lead to the need to completely replace the heating elements of the equipment. Conclusion Polyphosphate filters are the best option for protecting household appliances from scale. They are affordable and easy to install.

Info

It is also important to note that polyphosphate water filters with a large storage capacity and salt content should never be used for purifying drinking water or for prolonged contact with the skin. Is a filter harmful to health? It is important to understand that water that is purified using such a filter becomes technical and cannot be used for drinking or cooking.

Attention

Speaking about how harmful such a filter is for health, one thing can be said: it is undesirable to use it for direct consumption, since it is a chemical reagent, and accordingly, it is simply impossible to drink water from under such a filter. However, if you put your hands in it if necessary, a chemical burn will not occur due to the low concentration.

To ensure maximum protection of expensive equipment, it is recommended to periodically check the amount of reagent.

Polyphosphate filters

Tap water in each region has its own hardness level. And the softer the water, the less scale remains on the heating elements of household appliances, such as an electric kettle, washing machine, heating boiler, etc. To reduce the amount of nitrates and extend the life of expensive equipment, it is recommended to use special protective systems. Polyphosphate filters are popular fighters against the formation of scale and other chemical deposits on important elements and components of water heating equipment. According to experts, equipment that is used in conjunction with cleaning devices requires repairs much less often than devices that use untreated tap water. Purpose and application First of all, it is worth noting that polyphosphate filters are used everywhere and are quite affordable for purchase.

Forum

The most important thing is that, apart from periodically replacing the crystals themselves, no additional maintenance is required for the device. The device reduces the rate of scale formation, thereby preventing the breakdown of components and heating elements, a common cause of malfunction of which is the formed scale.

A polyphosphate filter for a boiler, according to user reviews, is the most affordable option for purifying water and extending the service life of equipment. What does the design consist of? The polyphosphate filter itself has a simple design:

Lid.
Main flask.
Drain.
Filler.

The whole process begins with water entering through the lid, and after passing through filtration, it exits through the drain and enters the water heating equipment.

Polyphosphate filter for water softening in the heating system

As a rule, without additional cartridge replacement, the maximum service life is about six months. The film that forms during the chemical reaction quickly dissolves under the influence of hot water.

Accordingly, when choosing a washing mode, the water heating should be no more than 55 degrees. It is also worth taking into account the fact that with the active use of a polyphosphate filter, deposits of calcium and other salts may form on the sides.

Unfortunately, getting rid of them is not so easy. Leaving them on the surface of a boiler or washing machine is also not recommended, since if the layer becomes too large, it will negatively affect the operation of the device.

Polyphosphate water softeners

Polyphosphates instantly begin to replace each other, enveloping hard salts, as a result of which the process of scale formation slows down. Types The modern market provides consumers with a huge selection of water purification devices. The filler can either be poured into a separate capsule through which water will pass, or placed into the technical device itself. By design, cleaning systems are divided into:

Flow-through.
Dosing filters.

Installing a filter The consumer does not always purchase and install a cleaning system together with a water heating device. Often, a water heater, boiler, washing machine or dishwasher is used without additional filtration of the incoming water.

Polyphosphate filters for water softening…

Hard water is a serious problem. It leads to rapid breakdown of expensive equipment, therefore, to protect washing machines and boilers, it is recommended to install a special polyphosphate filter for water softening. When passing through its filler - sodium polyphosphate, water is freed from impurities that lead to scale formation.

The principle of operation of a polyphosphate filter for water softening The design of the filter is quite simple. It consists of the following components:

transparent flask,
lid,
drain,
polyphosphate salt crystals.

The operating principle of the device is as follows: water, passing through the crystals, is saturated with sodium polyphosphates, and a film is created that envelops hard salts, so scale does not form on the heating elements.

This method has long been used at thermal power plants to prevent the formation of calcium scale and maintain the optimal pH and alkalinity of boiler water from the point of view of corrosion; treatment with trisodium phosphate (Na3PO4) mixed with alkali (NaOH) is used. Trisodium phosphate in an alkaline environment forms hydroxylapatite (Ca10(PO4)6(OH)2) with calcium ions, a loose mobile sludge that is easily removed with blowing.

So this is the method that filter manufacturers use. However, it has a lot of disadvantages that negate its effectiveness, for example - sludge corrosion; — formation of deposits of iron phosphate compounds in the zone of increased heat flows, leading to sludge corrosion and rupture of screen pipes; — formation of phosphate deposits themselves; — the phenomenon of “hiding” salts, i.e.

If you need to accurately dose the amount of salt, then resort to granules or powder. Previously, the polyphosphate salt index was previously focused on drinking water: a maximum of 7 grams per 1 cubic meter. meter. Exceeding this amount leads to serious diseases of the human body. However, even with a dosage of 5 grams per cubic meter. meter of water, it was not recommended for drinking. Today there are special salts that are food grade. A salt filter with such a filler is installed at the entrance to a house or apartment. The entire hydraulic network of the facility will be protected from limescale: sinks, showers, toilets, household appliances. Salt filters will be indispensable if there is no spatial possibility of installing a reverse osmosis filter or other water softener. The filter mass is filled in independently. The period of operation of the filter will depend on the flow rate, composition and temperature of the water.

Attention

In any case, it should be said that if the consumer does not use the available lime methods of water softening for his own benefit, the consequences will make themselves felt. Therefore, it is always more profitable to insure in advance. And some are insured.

There is one simplest and most accessible method for softening water at home. This is boiling water. But in this case you will have to boil all the water in the house.
It is physically impossible to perform this procedure. That’s why you won’t be able to insure yourself by boiling. This is another additional reason to use modern softening devices.

Moreover, today there is a choice, and even for different financial capabilities. It is best to build the process of softening water in an apartment according to this scheme.
The most economical lime method for softening water would be to purchase two softening units.

Polyphosphate filter for boiler and washing machine, benefits and harms of installation

Earlier, in the article “Methods of water softening. Ion exchange" section "Water" and subsection "Water softening" we touched on the topic of combating hardness salts and scale. In the last article, we looked at the actual definition of the word “softening water” and considered that there are several methods of softening - physical, chemical, extrasensory.
We also touched on one of the types of chemical water softening methods - ion exchange. In the current interesting article “Chemical reagent methods for softening water” we will look at chemical methods in more detail.

Info

Chemical reagent methods for softening water are varied. We have already examined a large group of these methods in the previous article - these are methods based on ion exchange, when hardness salts are replaced with twice the amount of sodium salts using an ion exchange water softener.

Important

The device is installed directly in front of the boiler and household appliances. It is necessary to make a connection in the pipe for equipment with a tap, then install a filter and then connect the equipment itself.

It can also be installed directly into the hose, from where water will flow into the boiler or washing machine. Before installation, the polyphosphate filter must be washed.
This can be done with running water under a regular faucet. This is to remove small crystals that may pass through the hose and clog the filter in the washing machine or dishwasher valve.

Why do you need a polyphosphate filter for a washing machine and boiler?

You don’t need to call a specialist for this - you can do all the work yourself. The simple design makes it easy to select a salt filter. The only difference lies in the polyphosphate backfill, which has different performance. Its quantity depends on the maximum permissible volume of the flask.
Important! Salt filters can only be used to remove salt from process water. Using filtered water for food purposes is hazardous to health. The only exception can be a special polyphosphate salt for drinking water. Using a salt filter for water as intended is completely safe. Sodium polyphosphate is not a toxic substance. If the laundry is not completely rinsed from salt, then it does not pose any danger to humans and children. Polyphosphates for the human body Polyphosphates are used in the food industry. These are polymers of phosphoric acid.

To ensure maximum protection of expensive equipment, it is recommended to periodically check the amount of reagent.

Salt water filter

After passing through such a filter, water becomes technical and cannot be used for drinking. There are several modifications of the filter on the market - capsules can be poured into a separate container or placed directly inside the equipment.

Structurally, the devices can be direct-flow or presented in the form of dosing filters. Is it worth installing a polyphosphate filter? If you do not install a polyphosphate filter, not only will the heating elements fail, but also the valves of household appliances will begin to accumulate scale.

This will lead to the fact that the equipment will spontaneously take in water, the rate of water heating will drop, and electricity consumption will increase. All this will sooner or later cause breakdown of expensive equipment. The filter will also eliminate the need for constant cleaning of washing machine valves.

4 Connecting the filter to the washing machine

The salt filter for water is based on polyphosphates, which work to soften the water. It is mounted in front of a device that requires a minimum salt content in water: washing machines, boilers, boilers and other heating devices.

Hardness salts lead to the formation of scale on the surface of household appliances. To reduce equipment maintenance costs, special filters are installed.

Soft water does not require a lot of washing powder and water softeners. Polyphosphate filters are not complicated in design. They consist of a plastic flask containing sodium polyphosphate crystals.

Using tap water does not always guarantee its purity. It often happens that centralized purification systems overlook such an important aspect as the limescale threshold in the water. And in order to bring the composition of water in order, you need to purify it. One of the convenient and, importantly, cheap options for help in this matter is polyphosphate filter. You can buy it almost everywhere, for example, in plumbing stores.

The principle of cleaning a polyphosphate filter, its disadvantages and advantages

It is impossible to leave water in its original form. Today, every consumer understands this. But for this centralized water and clean. How does it turn out that additional cleaning is also required without fail? In fact, the softness of water is a rather controversial and unproven fact. Hard water is not harmful to health. At least the direct one. Damage to equipment surfaces has been observed and observed. But, nevertheless, not every housing office can install a water purification system to remove limescale.

What does a polyphosphate filter do? Its main content is polyphosphate sodium salt. When water enters the flask of a polyphosphate filter for a boiler, the salts gradually dissolve. In this case, there is a rapid change from one salt to another. The water is massively saturated with sodium. But the principle of operation is different. Polyphosphate is absorbed by calcium and magnesium. A unique film is created on the surfaces of the boiler or washing machine. Lime salts do not stick to it. All the advantages of such filtering devices can be summarized in a table.

With all this, the polyphosphate filter for a washing machine has a sufficient number of disadvantages. For simplicity and cheapness, you will have to pay and pay with resource intensity. The approximate life of the cartridge without replacement is half a year !!! Since the backfill gradually dissolves, its quantity will have to be constantly monitored.

The film formed by the filter tends to dissolve in hot water. Therefore, the water in a washing machine, for example, cannot be heated to a temperature above 55 degrees. This also significantly limits the use of a polyphosphate filter for boilers directly for water softening.

Another extremely harmful feature of using just such a filter is that during the heating reaction, a new formation of calcium and polyphosphate is formed. It is very difficult to remove it from surfaces. And boilers often break down from such accumulations. Such filters should also not be used for drinking water or water with which the skin will come into contact! An increased content of neoplasms can lead to very severe allergies and irritation.

And finally, the last negative fact is the huge number of counterfeits of polyphosphate salts on the market. Since the device has a limited resource, it is mounted directly in front of a specific boiler or washing machine. If you buy it, then the polyphosphate filter should guarantee the uninterrupted operation of these devices.

The use of softeners really pays off. There are even simple facts that will tell you about the usefulness of softening. Whatever cleaning or detergent you use, it will all be alkali. And as a result, it turns out that working with lime water is guaranteed to increase the consumption of any detergent. In addition, fabrics from this reaction transmit water very poorly, accumulating both washing powder and water hardness. Such a bouquet of fabrics deteriorates very quickly, simply starting to tear in the most unexpected places. And this is just a simple example and simple harm.

The most common harm from low-quality water is the formation of scale on warm surfaces. The raid itself works flawlessly and accurately. And its heat-blocking property makes it very dangerous, especially for warm surfaces. A lot of problems immediately manifest themselves. The quality of water heating drops sharply, fuel consumption increases exponentially. And the risk of pipes bursting or surfaces cracking increases. The amount of scale requires constant monitoring and constant cleaning and prevention. And you definitely won’t be able to let this process take its course, since you can suddenly lose expensive equipment in a very short period of time. So, any softening method will be more profitable than washing and cleaning equipment surfaces from scale.

Features of the design of polyphosphate water filters, is it harmful to health?

The design of a filter filled with polyphosphate salts is as simple as it gets:

· Lid;

· Polyphosphate filler.

Water is fed into such a filter through the top, and the purified water is drained into the lower, bottom hole. Although the device is simple, there are several modifications. And they differ in the devices in front of which they can be mounted. These could be washing machines or boilers. Polyphosphate capsules can be located directly inside the device, or there may be a special container where they will be poured.

Structurally similar ones can also be direct-flow, or can be produced in the form of dosing filters. The latter divides the water entering the filter housing into two streams. One stream is treated with a reagent. That is, in one part of the body there is softening and treatment with polyphosphate salt. In this case, the amount of the reagent is strictly dosed.

The reagent can be used for such filters, both in powder and granular form. The device can be equipped with a special dispenser, which will not only allow you to constantly monitor the level of polyphosphate dissolution, but will also be guaranteed to add a strictly defined amount of reagent to the water.

The polyphosphate filler itself can also be different. Most often, translucent granular polyphosphate is produced and bought. Slightly less popular is the powder version. It is a white substance in compressed tablets. Sodium polyphosphate is also called Graham's salt.

Getting soft water in this particular case does not mean removing limescale salts from the water. Approximately the same way an electromagnetic softener works, a polyphosphate water filter works. Electromagnetic changes the structure of the salt, do not let it stick to the surface. The polyphosphate device creates a protective film, preventing salts from sticking. The very principle of operation of a polyphosphate water filter already suggests that it cannot be used for drinking water. But where can you buy it if there are only fakes and counterfeits around?

But for boilers and washing machines, such an invention is very useful. It helps protect the surface from the development of corrosion, in addition to protecting against scale. Also, the formed film inside the heated containers helps to soften old scale residues, which is also a big plus for the device. Without the expense and promotion of equipment, the consumer is able to wash out the old sediment.

As for the choice between granular and powdered backfill, boiler and washing machine cleaning specialists recommend choosing the powder option. It dissolves faster and more efficiently, helping to cover a larger area. But the service life of such a powder can be calculated very roughly. But this indicator is also influenced by the degree of lime in the water and the volume of water consumed. At the same time, the filler level must be constantly monitored.

When working with such backfill, you need to remember the rule. It is harmful to health because... it's a chemical reagent. If the amount of reagent has decreased to half the filling, then the filling should be completely changed immediately. This rule should be followed to maximize the protection of boilers from harmful deposits.

In its operation, a polyphosphate filter for boilers is very similar to ion exchange filters. They are also able to remove limescale from water to zero levels.

Some reviews about the polyphosphate filter

In Europe, such a Geyser filter is used to obtain drinking water. In Russia, polyphosphate filters are prohibited for use for drinking water, because reviews of their work are extremely contradictory. Polyphosphates are essentially additives that help maintain the consistency and shape of food products. You can buy them in any country in the world and in Russia. They were first identified in yeast and for a very long time. But today, it is harmful to health and is not beneficial for the human body. Unfortunately, it is hardly possible to drink water with such chemical surprises with impunity and without harm to health.

The filter competes with electromagnetic radiation. There are many reviews about the polyphosphate filter that confirm this. And its main trump card is the lack of replaceable parts. The service life is twenty to thirty years, in contrast to six months for a phosphate filter. The price of the filter is of course more expensive, but it is always more profitable. Therefore, it is better to save money by purchasing a more convenient and compact electromagnetic softener.

Derivatives of orthophosphoric acid or polyphosphates are substances that have found their use not only in the production of food for the population, but also in other sectors of industry: in the production of varnishes and paints, fire-resistant surfaces, and household chemicals. Today, the additive is increasingly used specifically to impart appropriate properties to various chemical substances, and less and less for food. Nevertheless, food additives under code E452 are still found in food ingredients purchased in stores and markets, since they are still effective stabilizers and emulsifiers and are considered relatively safe for humans.

History of the origin of polyphosphates, their chemical properties and production methods

The substance was first discovered at the end of the 19th century by the German researcher Liebermann in yeast cells. At that moment, there was no urgent need to synthesize food additives on an industrial scale, so the discovery did not receive much resonance. The identified element was examined, little by little studying its properties. In the 40s of the 20th century, the production of polyphosphates from orthophosphoric acid acquired significant scope: the emulsifying and stabilizing effect of the substances, as well as their relative safety for humans and the environment, opened the way for them into the food industry, and, as it turned out later, into the chemical industry.
In modern production, the additive is used as an emulsifier, stabilizer, water-retaining component, color fixative, fiber degreaser, softener, as an element of various detergents.

Polyphosphates, as salts of metal ions, in the cells of the human body are responsible for regulating the amount of cations, and also participate in the formation of platelets. The level of blood clotting partly depends on them.

To obtain a substance, phosphoric acid is first combined with an acid salt of a particular metal, after which the process of dehydration of this organic compound occurs, most often by heating. Another way is to neutralize the acid with ammonia. Ammonium polyphosphate is synthesized in this way.

Externally, the substance looks like a white or colorless powder, consisting of crystals, granules, plates or flakes.

For ammonium polyphosphate, a slight smell of ammonia is allowed, for other types of polyphosphates, there is no smell and taste. The substance dissolves well in water and acidic media.

Types of food additive E452

Obtaining polyphosphates can occur using various chemicals: salts of potassium, calcium, hydrogen nitride, and others. There are these types of substances:

sodium polyphosphate or Graham's salt;
potassium polyphosphate (Curroll salt);
sodium calcium polyphosphate;
calcium polyphosphate;
ammonium polyphosphate.

Using a component in production

The food industry is slowly but surely moving away from adding E452 to the composition of manufactured products. However, polyphosphates can still be found in the following foods:

frozen fish and seafood;
fresh, dried and processed fruits, fruit preserves and (the substance is used to compact the fibers);
and some types of hard ones (to provide heat resistance);
bakery products with (polyphosphates perform a nutritional function for yeast, improve the consistency of bread, and increase the weight of the finished product);
sausages and sausages (the substance in them retains moisture and also allows you to preserve the original color);
, including dairy desserts (emulsifier E452 helps give products a uniform consistency);
canned fish and meat (to slow down oxidative processes);
flavored soft drinks, dry mixes for athletes, milk-based drinks.

The use of polyphosphates is intended to improve the taste of the product, extend its shelf life and increase its yield.

In addition to its value in food production, the additive is widely used in the manufacture of fire-resistant coatings. E452 prevents the spread of fire and reduces the flammability of the treated surface.

The component is also found in toothpastes. Manufacturers claim that polyphosphates protect tooth enamel from acids and also prevent the formation of tartar and plaque.

The substance is added to cleaning products (powders, gels, creams) to soften water and prevent the formation of scale, for example, in washing machines. In addition, sodium polyphosphate in washing powders and gels allows you to avoid clothes becoming gray or brown after washing. The substance is used to treat metal parts, as it prevents corrosion. Adding polyphosphates to running water that interacts with metal coatings also saves them from rust. Substances are often used to protect various cooling systems. The additive is not suitable for softening drinking water.

Sodium polyphosphate has also found its use in photo printing, in the pharmaceutical and textile industries, and in agriculture as a fertilizer.

Methods of packaging a substance

Manufacturers of the substance store and transport it in various containers. The main requirement for any type of packaging is the presence of an inner layer of polyethylene. E452 can be stored in multi-layer paper bags and bags, in synthetic fiber grocery bags (in these you can usually see cereals or flour), in cardboard boxes. Transportation and storage is also allowed in plastic containers, but made exclusively from food-grade plastic.

Safety of the substance, possible harm from use

Despite the fact that polyphosphates are widely used in various types of production, daily contact with humans and the environment, they are only conditionally safe substances. Their use in food is acceptable, but only in limited quantities.

On average, the maximum amount of supplement consumed per day should not exceed 70 mg per 1 kilogram of adult weight. Substances do not bring special benefits, however, they participate in the process of blood formation in the human body.

Food additive E452 is approved for use in Ukraine, Russia and a number of European countries. However, studies of polyphosphates have recently increasingly given alarming results: they indicate that the use of phosphoric acid polymers has a negative effect on the human body, as it contributes to the accumulation of phosphates in the body. Phosphates, in turn, are carcinogens and provoke the appearance of tumors. The harm of polyphosphates lies in the fact that the additive can increase the level of “bad” in the blood, thereby causing vascular and heart diseases.

The constant use of a stabilizer in a dosage exceeding the permitted one leads to problems with the digestive function, dehydration of the body, and disruption of metabolic processes in cells. There is evidence of the possible occurrence of diarrhea, intestinal dysfunction, vomiting with an overdose of polyphosphates.

International standards for polyphosphate content in food

Given the relative safety of the substance, its amount in human food is strictly regulated by the legislation of the European Union, the Customs Union and the norms of each specific country at the domestic level. For example, legislative requirements in the Russian Federation say that bakery products per 1 kg can contain no more than 20 g of food additive E452, milk, ice cream and alcoholic beverages - no more than 1 g per 1 kg of mass, in cheese and – up to 2 g per 1 kg of finished product.

Judging by current trends, the era of polyphosphates in food is gradually ending. Today, the manufacturer, although primarily interested in his own profit, is gradually refusing to add the substance to food products. Studies show that an element that is found in small amounts in the human body and even participates in important processes in it is still not completely safe. As a water softener, anti-corrosion agent, fertilizer and anti-scale agent, polyphosphates are used much more frequently today.

When purchasing products, it would be a good idea to carefully study the composition indicated on the packaging for the presence of a component with code E452 - if it is detected, the consumer will most likely be able to find an alternative that is safer for his own health.

When passing through its filler - sodium polyphosphate, water is freed from impurities that lead to scale formation.

Operating principle of a polyphosphate filter for water softening

The design of the filter is quite simple.

It consists of the following components:

transparent flask,
lid,
drain,
polyphosphate salt crystals.

There are several modifications of the filter on the market - capsules can be poured into a separate container or placed directly inside the equipment. Structurally, the devices can be direct-flow or presented in the form of dosing filters.

Another useful property of the device is the ability to dissolve already formed layers of scale. And the softer the water, the less detergent is required for washing or washing dishes.

Why can't you drink water after a salt filter?

Polyphosphate filters are designed to purify only process water for one simple reason - polyphosphate is a toxic substance. Moreover, at water temperatures above 40C, polyphosphates are destroyed and become ineffective.

Install this water purification device exclusively for domestic purposes!

VIDEO INSTRUCTION

How often to change and clean the polyphosphate filter

The filler consumption is quite economical - 3 grams per 1000 liters. As you use the crystals, they dissolve, so they need to be topped up periodically.

Manufacturers recommend completely replacing the contents of the flask if the volume of crystals in it has decreased exactly by half or if the filling of the flask has not changed over a long period. On average, as practice shows, the service life of the device is about six months.

The device is installed directly in front of the boiler and household appliances. It is necessary to make a connection in the pipe for equipment with a tap, then install a filter and then connect the equipment itself. It can also be installed directly into the hose, from where water will flow into the boiler or washing machine.

Before installation, the polyphosphate filter must be washed. This can be done with running water under a regular water tap. . This is to remove small crystals that may pass through the hose and clog the filter in the washing machine or dishwasher valve.

Why do you need a polyphosphate filter for a washing machine and boiler?

While I have my eye on this filter with polyphosphate backfill http://www.eldorado.ru/cat/detail/71043958/ it is placed in front of a washing machine or dishwasher and, as they say, it completely protects against scale for about six months ... then the backfill is added and the process goes on .
There is no need for any calgons.
Filling in M Video costs 800 rubles per 1 kg, probably enough for three years.
There is also a more serious option for a flask of SL 10 format http://www.eldorado.ru/cat/detail/71007405/ enough for a year, backfill can also be added..
Actually the question:

I have never met a single machine that died from scale. The Siemens, bought in 1998, lived for 10 years and was thrown out because the powder tray fell apart, the brand's belt broke, once they didn't pay attention, a large stone got into the drum (one of the small ones shoved it) - it bent the drum, The machine was about 7 years old, it was sent to the trash heap, Kandi's power board died. LG, Atlant both worked and continue to work. IMHO, both calgon and water softening filters are a waste of money. Calculate how much money will be spent on this task in 3-4 years, it will be easier to buy a new machine, unless you bought some expensive miele (I don’t know what it’s needed for), because besides scale there are a lot of other possible reasons for breakdown , as a rule, more likely

And then there’s another point - do you often wash at temperatures above 60 degrees? As far as I remember, there were only a few such cases, rarely what things can and should be washed with boiling water, and at a lower temperature, deposits of insoluble salts form much more slowly. And if you really need to soften water cheaply, there is soda ash, essentially the same advertised calgon, only for almost nothing.

well, in principle the money is small (about 500 rubles per year) it definitely won’t be worse, as long as it’s worth it :)
Well, God bless her, the car... but the boiler?
how to protect it from scale?
The flow-through gas heater lasted me about three years, then temperature fluctuations and a decrease in performance began.
I installed a 115-liter gas storage boiler, it worked for 2 years, everything seemed fine, but water hardness is not good for it.

wizard_s I completely agree. I saw disassembled machines, I didn’t see scale like in the advertisement. But if it does form, you can change the ten

But hard water really kills a boiler

The Electrobolers have a magnesium anti-scale electrode, it is recommended to change it at least once every two years. I have never installed Geyser filters; they are not easy to install; I use “New Water” filters. There is no clear answer to softening water; it is more important to purify water from mechanical impurities; 1-5 micron cartridges can handle this.
P.S. I professionally deal with plumbing, sewerage, heating

Well, powders now already contain a softening additive, and it’s written on them that you don’t need to add anything.

Don't take it out unnecessarily
Do not remove without honor.

Actually the question:
Has anyone used similar things and is there any real benefit from them???

Judging by the technical descriptions and price, is this product positioned on the market as universal?
I read it and suddenly remembered about mineral water. I recently bought a 5 liter bottle purified drinking water in the Magnit chain of stores. I'm boiling. In the kettle there is a film-like coating on the water.
My water supply is soft. Only it contains a suspension of clay. There are practically no carbonate scales . There are no such films as described above either.
I compare and slowly begin to suspect that there is no universal technology for purifying water from organic, colloidal, chemical impurities and bacteria. Each impurity is purified using its own technology.
— organic matter and finely dispersed suspensions are purified by filtration or settling or removal from sediment (mud, algae, clay, .... yeast.)
- chemicals are “neutralized” with reagents
— biological contaminants are cleaned by chlorination, ozonation, etc.
What is certain is that any filter has a performance limit. The higher the purification rate, the lower the water quality. That is why all city water treatment plants thresh it all day long and accumulate it in special containers. . All this water will be consumed by the population within a few evening hours (the so-called peak consumption). But all this is about drinking water.
But water for city boiler houses doesn't matter pre-prepared. The reason is the irreversible decomposition of soluble impurities during the heating process and their transformation into insoluble ones. See the chemical table of solubility of metal salts.
Victor, decide on chemical analysis of water in the SES laboratory. Maybe they can suggest something? Unless, of course, they are “in share” .
But you can only guess how polypropylene pipes and a cesspool will behave as a result of using the proposed polyphosphate balls. I can assume that there are no side chemicals in the copper pipe. no reactions will occur.
PS At the exhibition in Chelyab I saw technology for purifying and “softening” water using magnetic fields - exotic.

Today I bought a reverse osmosis water filter for the kitchen, and at the same time in the store I monitored the topic of water softening for the washing machine and boiler...

So far I have my eye on this filter with polyphosphate backfill

http://www.eldorado.ru/cat/detail/71043958/

it is placed in front of the washing machine or dishwasher and, as they say, completely protects against scale for about six months...then the backfill is added and the process continues.

There is no need for any calgons.

Filling in M Video costs 800 rubles per 1 kg, probably enough for three years.

There is also a more serious option for an SL 10 format flask

http://www.eldorado.ru/cat/detail/71007405/

enough for a year, backfill can also be added..

Actually the question:

Has anyone used similar things and is there any real benefit from them???

Take it and use it... there is no harm in water heating elements with a small flow!!! BUT!!! absolutely not for drinking purposes!!!
PS. ...the polyphosphate will gradually dissolve - which will be visually visible in a transparent flask - you can refill it...
ZYY. … I’m a firm believer in ion exchange resins for “softening” water…

Who is this genius???!!! Let me shake his throat!

Have a nice day, everyone!

I want to clarify this. Everyone has long known about the dangers of phosphate powders.. But there is this thing with polyphosphate salt, which is put on the pipe in front of the washing machine to soften the water and reduce scale. We installed one of these once, and now it suddenly dawned on me: our powder is bio-based, but we still pour polyphosphates into the sewer?

Composition of polyphosphate salt:

P2O5 - phosphoric anhydride, when interacting with an excess of warm water, it instantly turns into phosphoric acid
Na2O - sodium oxide
Pb - water has no effect on lead
As - arsenic itself is not poisonous, but all its water-soluble compounds are extremely poisonous
NaСl - table salt
Na2SO4 - sodium sulfate, one of the main components of synthetic detergents
F- free fluorine does not occur in nature
Fe2O4 - iron oxide, magnetite - abrasive material used for grinding stone
Ca - due to its high chemical activity, calcium occurs in nature only in the form of compounds
Zn - the earth's crust contains zinc in the form of the mineral spharelite (zinc blende) ZnS
Cu - water does not affect copper, the largest copper nugget was found in one of the Great Lakes, weighed 420 tons.
Cd - cadmium does not occur in free form in nature (taken from here) And what happens? Are they selling some nasty stuff under the guise of washing machine protection? (Well, this is not surprising, of course...).

And one more question for everyone who uses bio-powders. What kind of prevention do you do against scale in your washing machine?

Thanks to all!

Hi all!
The hard water house has a gas boiler and a washing machine. One water treatment company advised me to buy a polyphosphate filter. . But as I was told, drinking water after these polyphosphates is prohibited, only for those. needs! Is it so? Is it really harmful to health or can the same filter be installed on the water supply (boiler)? I ask for your comments and feedback.
Thank you!
