High water rigidity, determined by the content of calcium and magnesium salts, is a problem that is relevant for urban apartments and country houses. How to deal with it?
According to the statement of physicians, it is the high content of rigidity salts that contributes to the development of hypertension, sclerosis and urolithiasis (but without these compounds, the normal operation of the cardiovascular system is also impossible, because it is completely impossible to remove them from the water). Unquided and consumer properties of hard water. It causes the reservoir of detergents when washing and bathing by 30-50%. Meat and vegetables are poorly welded. Aquipped hard water greatly worsens the taste of tea and coffee.
For plumbing and household appliances, rigid water is a real catastrophe. Is it going on with autonomous hot water and heating systems? It has been proven that thickening with a thickness of 1.5mm, formed on beans, increases the energy consumption required for water heating, by 15%; layer 3mm- by 25%; At 7mm, this indicator reaches 39%, and at 10mm- 50%. In other words, the heating of the water through the layer of scale can be compared with an attempt to warm it in thermos-dear energy simply flies into the pipe. However, the trouble is not only in the overexposure of "fuel", but also in the fact that the excess heat that the heating element has allocated, and the fluid did not receive, it is spent overheating by himself, as a result of which it fails. In addition, a scale formed on the heater and pipes, interacting with water (hydrolysis of magnesium salts), increases its hydrogen PH potential. It enhances the corrosion of the systems as a whole. To combat scale, appliances are offered, the main part of which is a magnet.
How to reduce water rigidity
Existing ways to reduce water rigidity can be divided into traditional and non-traditional. It includes the ion exchange method (used in softener filters), processing with membrane filters (all salts are removed from the water), use of different inhibitors (in particular, polyphosphates) IT.D. They wrote our magazine repeatedly.Today we will tell about one of the unconventional ways. This is a water treatment with a magnetic field, which is used mainly to combat science. This method is characterized by simplicity, cheap, safety, environmental friendliness, low operational costs. The water underwater does not acquire any side, and even more so harmful to human health properties, does not change the salt composition and retains taste. Magnetic processing devices appeared more than 40 years ago. Recommendations for their use are given in a number of SNIPs regulating the operation of heat points and networks. (Another non-traditional method, which is something like akin to magnetic exposure, is a radio frequency water treatment. He is so new that there is no mention of it in any Snip.)
Water and magnetic field
From the very beginning it should be emphasized that the processes occurring with water in a magnetic field are studied little, therefore there is no single slender theory in this case. However, there are several hypotheses of the impact of the magnetic field on the ions of salts dissolved in water. In our opinion, the following is most clear (we give it in a simplified form).
Water molecule can be represented as an elementary dipole particle with positive and negatively charged poles. Under the action of the forces of mutual attraction, the dipole of water form so-called clusters, and not by themselves, but uniting around the microparticles present in the water and the impurities ions (in our case CA + and CO3-), without giving them to interact with each other. When the water is heated, the cluster structure is destroyed, and the ions, connecting, form calcium carbonate Caco3, which is deposited on the heaters and pipes, creating the basis of scale.
What happens when the magnetic processing of cold water? When the water dipoles pass through the magnetic field, the Lorentz power acts on them, which causes dipoles to perform oscillatory movements. Of course, if a magnet is one, then dipoles will make one oscillation, and it will not lead to the destruction of clusters. But if the magnets are somewhat and arranged so that at a short distance the magnetic field changed the direction more than once (this principle is implemented in devices on permanent magnets), or if the processing is carried out by a variable magnetic field (with electromagnetic effect), then the probability of the decay of clusters increases.
The microparticles released in the destruction of clusters become as if crystallization centers, which are preferred to be precipitated from the ions of the SAS3 molecule. Next, the process acquires avalanche-shaped characteristic of the surface of the resulting microcrystals, all new molecules are attached. Thus, the CACO3 crystallization occurs in the volume of water, and as a result, instead of a solid pyro-called amorphous calcite, fine particles of aragonite appear, which have completely different than scale, crystalline structure. They migrate along with the stream and can be easily removed using an ordinary filter. When the water is heated, the size of such particles increases, but the scale is not formed.
But on this tricks do not end ... Calcium ions begin to stand out from the already scattered scale and join the newly formed microcrystals floating in water. As a result, the old scale is loosened and is even completely washed off from the surface of the pipes and heating elements (deletion of deposits occurs gradually and takes from 1 to 4-6 months). Moreover, over time, a thin dark film is formed on pipes and heat exchangers, consisting of higher iron oxides (Fe3O4, Fe5O6), which protects equipment from corrosion (the rate of corrosion reaction, as confirmed by experiments, decreases by 40-75%).
From theory to practice
How to implement magnetic protection in practice? In apartments, such devices should be installed on entering both hot and cold water. Covers with autonomous heating systems and hot water supply - in the introduction of cold water. It should be borne in mind that the effect of magnetic processing is manifested during a certain time (from 8h to 5 days, during which the so-called water relaxation occurs). The duration of this period depends on the chemical composition of water, its temperature and operating conditions. That is why in the closed heating systems, in addition to the "Ocagination" of the feeding, it is necessary to place another device, which should process the water circulating in the system, and thereby create the so-called antirelaxation circuit.Local protective devices at the input of water can be installed in gas columns, boilers, household water heaters, coffee machines, washing and dishwashers, as well as climatic systems operating simultaneously in moisture and air conditioning. Magnetic devices are used in conjunction with the water treatment system (which allows you to increase the duration of the filter service), as well as in the complex with units that purify the water of the pool (this extends the service life of pumps and water heating devices).
It should be especially emphasized that magnetic devices are not a panacea when solving the problem of rigid water, and cannot be considered softener filters and are not suitable for processes where soft water is required. They only activate (convert) water, leaving its chemical composition practically the same as the impact, and in most cases only help prevent the formation of scale. The modern Russian market offers two basic types of apparatus for magnetic water treatment - with permanent magnets and electromagnets.
Permanent Magnet Devices
These devices have a relatively simple design, do not consume electricity and differ in absence of problems associated with electrical safety and repair with electrical test of windings. They are easy to install and maintain, are characterized by high reliability and durability.
To create magnetic devices, such materials such as magnetiferrites (a mixture of polymer or mineral binders and powdered magnetic fillers) and ferromagnets (widespread use of ferrite barium) were even recently used. In the early time, the magnets based on rare-earth metals are more popular. The most "strong" of them are the materials of the neodymium system. They are compact, do not lose their qualities at temperatures up to 120 ° C and over time (the loss of magnetic properties is only 0.2% more than 10 years).
Based on magnets, compact devices of a new generation - magnetic activators of water (MAV) have been developed. They are built on the principle of cyclic effects on the water of several placed inside the device of magnets (the so-called multipole magnet). Structurally, they consist of a cylindrical housing made from a magnetic material (serves as a magnetic core and closes the field inside the machine), and inside its magnetic element. On the ring gap between them and the water passes.
The MAB housing is made of stainless magnetic steel or galvanized steel pipe and from the ends is provided with fittings with internal or external thread or flanges (with their help MA and connected to the pipeline). Fittings are made of stainless steel or brass (it is polished outside, which improves the appearance of the device). True, in the case of the use of brass, the manufacturer is forced to protect the device from electrochemical corrosion (fastening fittings with a housing through an IT sealant).
The magnetic element is a thin-walled tube made of stainless non-magnetic steel, inside which are located certainly oriented permanent magnets in the form of disks. The ends of the tube are equipped with conical lugs-fairies and centering crosses (they are also made of stainless steel and welded with argon-arc or laser welding).
It is worth noting that the device described only seems to be easy to create it is necessary to carry out the most complex calculations. First, the ring gap between the body and the magnetic element is obliged to have a strictly defined value, which ensures the specific flow rate and its magnetic permeability. Now, the cross-sectional area of this gap (estimated by the diameter of the conditional passage) should be comparable to the area of the pipeline passage in which the device is embedded, so as not to cause the hydraulic resistance and the pressure drop in the system. Secondly, it is necessary to design the geometry of cone tips and centering crosses to the gap flow of water in the gap during the pressure range to which the device is calculated (it is indicated in the passport), was exclusively laminar (not vortex), otherwise the processing efficiency will be reduced repeatedly. Thirdly, the magnetic element is designed to provide the necessary magnitude of magnetic tension in the gap, as well as create a magnetic field, which, when moving from the pole, changes the direction to the opposite, with a strictly defined number of times, otherwise it will not be a sense of processing again .
Magnetic activators market
Now these devices offer many company-domestic, from near and far abroad. Ipractically each manufacturer gives devices its own names. Thus, the company "Energofinsservice" called them by household appointments, "Runga" and "EINIS-SG" - hydromagnetic systems (HMS), "MVS Kema" - magnetic polygraph activators of water (MPAV), "Magnetic water systems" (all- Russia ) - magnetic water transducers; Petrometalsnab (Russia) and "Ross" (Ukraine) - devices of magnetic treatment of water (minds), "Sevastopol plant of utility equipment" Hammer "(Ukraine) - water-chapters (Navy). But no matter how much their manufacturers call them, all They are magnetic water activators (MAV) and are arranged in the manner described above.Equipment of each manufacturer has certain differences, even if small. So, "Runga" uses for the manufacture of cases and connecting fittings of its devices only special stainless steel. "MVS Kema" until recently made corps and fittings only from magnetic stainless steel, and in the production of the magnetic element, exclusively laser welding was used, which does not allow heating magnets. There are several months ago to supplement the line of cheaper products, the company has released a novelty of the MA series in galvanized steel housings without fittings (connected using standard connecting elements used in the installation of pipelines). The company "Magnetic Water Systems" traditionally offers their MA in galvanized steel housings with polished brass fittings.
Devices manufactured by most companies are offered in two series of household (the diameter of the conditional passage - DU 28-DU32, the fittings of the threaded) and industrial (Du more than 32, compounds are threaded or flanged). The smallest of industrial MAs are suitable for installation on the input of water in the cottage.
Interestingly, at once, three firms ("EINIS-SG", "Magnetic Water Systems" and "MVS KEMA") almost simultaneously released a nominel-compact MAV for the installation on a washing machine. The thread of the fittings of these devices in accuracy corresponds to the standard sizes of the washing machine compounds - for installation, it is necessary to simply unscrew the fitting of the water supply of the hose, fix on its place MAV, and then screw the hose on it.
Do not think that firms simply copy the design of each other. Thus, in a magnetic activator of water produced by Pretchellsnab, water flows through the PVC tube, to which "ports" five ring magnets. This magnetic element is enclosed in a steel housing with end plugs.
It differs in the design and apparatus of AMPM (the device magnetic on permanent magnets), manufactured by the company "Energotrast" (Russia). The case of stainless steel (12x18n10t brand) water is treated with a magnetic field created not in the ring, but in a rectangular gap. The devices designed for the service life of at least 30 years are offered in three modifications: AMPM 2, AMPM 5 and AMPM 10 (the number in the instrument mark corresponds to the performance measured by VM3 / h). Dimensions: 6030-220135mm. AmPM price ranges from 10,000 to 22000 rubles.

All countries will visit us
It should be noted that the secrets of the design of devices on permanent magnets entering us from abroad, manufacturers are not disclosed. Do not hurry to understand this issue and domestic sellers selling them. Therefore, we just present the information that we managed to get, and we will try to refrain from commenting.
Aquamax (Italy) offers an Ecomag instrument series, which includes several models. So, Ecomag 035, 300, 350 and 400 of universal use have the form of a compact box, which is simply attached to the pipe without dismantling the water pipeline. Price - 1344-8763rub. Ecomag 010, 030 and 032 devices are designed to work in a pair with water heaters. There are models for use in heating and water supply systems: ECOMAG 150, 240, 250 (have an internal thread under pipe with a diameter of 1 inch) and Ecomag 500 and 550 (with an external thread under pipes with a diameter of 1 or 2 inches). Price - 24472-28392rub. Special model with plastic connectors for installation on washing and dishwashers - Ecomag 085. price- 924 rub.
MEDIAGON (Mediagon, Switzerland) except for permanent magnets there is a special device, manufactured, according to its developers, a method for pressing materials such as aluminum, iron, chrome, zinc, silicon IDR., And (hereinafter quoting literally) "effectively concentrating electrostatic Environmental fields "(these fields are used to treat water in combination with weak magnetic fields). Mediagon consists of two parts that are fixed on a pipe on any direct (16-30 cm) vertical or horizontal area (the dismantling of the pipes is not required). The device is successfully operating at temperatures up to 100-120C. The cost of devices intended for use depends on the diameter of the pipes to which they are installed (from 1/2 to 11/4 inches), and ranges from 33650 to 38760 rubles. Dimensions - from 16014090 to 160160100mm.
Is the same aspect we comment on the same aspect. In the text of the information attached to the listed imported devices, fixed on the pipe without cutting, you can meet the following phrase: "The material from which pipes are made does not affect the operation of the device." It is this phrase that causes bewilderment: what tension should have a magnetic field created by the device so that it penetrates through the steel pipe with a diameter of 2 inches from the wall thickness of about 3.5mm? Maybe the pipe is still a polymer, metal-polymer or copper? Then said in the information sheet is quite fair. Probably, manufacturers and sellers should figure it out.
Electromagnetic systems
The processes occurring in these devices, which means that the protection of the equipment from scale is almost similar to what is happening in MA on permanent magnets. Avota principle of operation is absolutely different, since the source of the magnetic field is electromagnet.Perhaps the most simple ABS device (Magnetic armor solenoid) for electromagnetic processing of water offers the company "Energotrast". It consists of two sections separated by a diamagnetic ring. Inside sections placed radial and annular magnetic pipelines, the removable electric coil is mounted outside. Water treatment occurs when the direction of the magnetic field changes during the transition from one section to another. Dimensions of the device - 200135mm. Massive-8kg. Credible power is 40W. Service life - 10 years. Price - 11000rub. The compartment includes a power supply 220 or 220 / 36B.
Pretty curious Hydroflow electronic devices (Hydropath, United Kingdom). The device is an electromagnetic low power generator, controlled by a microprocessor, which is installed on top of the pipe. According to manufacturers, the main advantage of the device is that when it is work, the frequency of fluctuations of water dipoles is determined by the frequency generated by the generator, and not the speed of water movement, as happens, for example, in the zone with multidirectional magnetic fields of MAV devices. The result is the destruction of clusters (and therefore the formation of crystallization centers) occurs intensively. For the same reason, Hydroflow functions in a wider range of water flow rates and even in the "standing" water (that is, in the absence of a stream when the crane is closed).
The manufacturer also declares that the device works consistently on the water with an exceeding PDC calcium and magnesium 8 times and above. There are positive results of its use on water with an elevated content of iron, silicon and even on sea water. The models are selected by the diameter of the pipe at the installation site. Powered by 220V network. The cost of the HS-38 device, intended for installation on pipes with a diameter of up to 1 inches, is 10400 rubles., HS-40 for pipes with a diameter of up to 2 inches- 46200 rub.
Water King (Russia) offers instruments that cultivate water flowing through the pipes by electromagnetic waves of a specific frequency range (it is close to sound). These waves are more than 350 holder signals, modulates a special microprocessor placed in a hermetic case (it is capable of working even with a relative humidity of 100%). These waves are transmitted into water through winding winding around pipes. As the organs certified by the products are confirmed, the waves are absolutely harmless to humans. The devices are powered by a voltage of 220V and are capable of functioning at temperatures up to 70c.
All the devices include nine devices, four of which relate to domestic, and five industrial. The most compact from household appliances - Waterking Sentry- is installed on one pipe. Waterking 2 is used for simultaneous treatment of water in two pipelines (you can install hot and cold water pipes in the urban apartment). Waterking 31 can stagnate water in a pipe with a diameter of up to 64mm and is suitable for installation in the cottage.
A competitor to the company Water King in the Russian market is the Alphahech Group of Companies, which has already produced the fifth generation of instruments "Termit". The principle of their action is very similar to the just described. The devices are released in three modifications: household ("Termites", "Termit Lux") and an industrial series ("Termit-M"). "Termitic Suite" Compared to the Device "Termit" has an improved design and costs 750 rubles. more expensive.
Bauer Watertechnolo-Gy (Finland) offers Bauer PipeJet (PJ) devices for water treatment with a variable magnetic field. The device consists of two parts: an electronic control unit with an integrated microprocessor and an assembly unit. Lovely water supply systems The device on entering is simply crashed into a pipe with threaded fittings. Rearmed heating systems, it can be installed both directly on the pipe, and in parallel to it on the bypass line (bypass should be separated from the main pipe at an angle of 45, otherwise the effectiveness of the processing efficiency is reduced). Three of the eight models offered by the company can be attributed to the KBBYT, the price is 51200rub.), PJ-321 (5-10m3 / h, 119400rub.), PJ-401 (15m3 / h, 153500rup .).
Ocagnetic water and harvest
It has been established that if you water the plants with water that has passed magnetic processing, this will allow you to increase their yield by 20-40% and reduce the ripening time of fruits. These results were obtained by scientists of the Stavropol State Agricultural University in the study of the use of water treatment devices for irrigation of various crops, in particular tomato seedlings.
Our comment
As the English physicist J. Bernal said correctly, "water, this oldest of secrets, forever puts in a dead end of physicists and chemists." Iz, the water itself is still a secret even for scientists, then the processes occurring in it with magnetic processing is the more a riddle. Well, the mysteries, especially mysterious devices that produce invisible processing, do not like. Therefore, apparently, and do not apply. Azry!
In this article we mentioned not all manufacturers working on the market of this product, and told not about all existing types of instruments for magnetic water treatment. However, we hope that we managed to at least minimize the verge of mysteriousness associated with the use of these devices. Apparently, their widespread use will allow hot water to flow from the crane all year round without a break for cleaning heat exchangers from scale. The heating istes will begin to warm us so that even in the most jubilant frosts will not need any additional heaters. Astiral, dishwashers and other machines that facilitate our hard life, even without such a means like Calgon, will work almost forever.
