According to consulting company "Realekspo", today in Ukraine there are about 600 cottage villages and towns, not including individual dwellings in villages and towns. The number of people residing in an individual house, grows, and treatment issues country-house is becoming more urgent.

Artesian wells

Today, Ukraine is mainly used, water from open water bodies - rivers, lakes. This water is used both in industry and for drinking. However, in recent decades for the needs of housing and communal hazyaystva increasingly used artesian water, and in private homes well become the only source of water.
Traditionally it is considered that the artesian water is purer than water from open reservoirs. At the same time, already a dozen years of independent research on water quality in different countries speak about pollution, not only the commonly used water from the fresh waters of rivers and the second aquifer, but also defined as virtually pure water from the deep "artesian" wells. Human activity has affected even those water supplies, which were protected by nature with great care because of the filtering ability of many kilometers of ground. It would be naive to believe that the use of independent sources of water supply (wells, boreholes) ensures clean water.
Hardness of water
In the composition of water from an artesian well enough a lot of pollution that can harm the health, but also household appliances.
In addition, water from artesian wells, usually used in a private home and cottage has a fairly high compared with the river water level of rigidity. In particular, in Ukraine the average hardness of river water is 2.7 - 3 mg / l, and water from wells - more than 7 mg / liter. Tighter water provokes the formation of a layer of scale on appliances and heating systems, and lime, it produces creates a threat to damage the heating elements. Therefore, experts advise in matters of water treatment in a private home pay special attention to methods for reducing water hardness, which can combat the negative effects of scale and lime deposits.
Director of Elite Edelweiss "Julia Belskaya notes that deal with scum and lime scale in Ukraine today, in most cases prefer the old fashioned way, by applying for this chemical or mechanical cleaning equipment. "When heated, hard water, hardness salts in excess contained in it to precipitate, forming a stubborn deposits on the walls of equipment. As a result, we see a narrowing of the lumen tubes and channels, which leads to lower efficiency equipment, reducing the pressure of hot water, etc. Limescale incapacitate it, to what they are destined to accumulate. Equipment that is not yet operational, but exposed to hardness salts, performs its functions is much worse. For example, only 1.5 mm layer of lime reduces the heat radiators 15%, and for heating hard water require 15-20% more electricity, "- she said.

Cottage aquaculture

According to Victor Kovalenko, the director of consulting firm Real-Expo, which conducts market research cottage villages throughout Ukraine, currently the main sources of water in the cottage are just that artesian wells and water treatment virtually every homeowner deals on their own. Centralized water supply systems in a cottage village there is little, and in their creation no one's interest, - said Victor Kovalenko. - People move to the cottage to get away from the problems of public utilities and to determine what they need. However, often the decision on the need for some water treatment systems are accepted only because so did a neighbor, and the lack of professional approach does not introduce new methods of water treatment. People do not use the new items just because they do not know about them. "
According to Yuri Fedkiva, director of one of cottage townships, Kiev region, existing since 1997, the separate and individual farming each owner can not use a centralized water system. "In our town, only four households are connected to the water tower. All other cottages are used well. Of course, each house water purification system installed, but they are aimed primarily at the elimination of bacteriological contamination, eliminating odors, rust, mechanical particles. Such systems are virtually struggling with a high level of water hardness, which in our town is about 4.9 mg / l ".
According to the specialists involved in the operation of individual households in a cottage village, average monthly costs for water treatment in the estate, located in an area of ??about 20 acres, is about 450-500 USD. This amount usually includes water treatment with coal, manganese and salt filters, as well as treatment with ultraviolet light. Average consumption of treated so water is about 50 cubic meters per month. Additional combat hard water which is heated and used in heating systems, as a rule, no one is - the cottage owners and managers of real estate believe that the salt filter enough. However, the salt and manganese in water supplies to the cottage area of ??200-250 sq.m. annually must spend up to 4000 UAH.

Anti-scale filter without

To deal with limescale and scum allows reagentless electromagnetic water treatment. This method does not require water treatment chemicals and energy costs and is completely environmentally friendly. Electromagnetic transformers are specially designed to prevent the formation and elimination is postponed scale on the walls of pipelines and heat exchange elements may be included in all units, subject to the formation of scale and corrosion in service. This treatment resulted in water instead of lime produced finely easily remove the sludge.
In addition, the electromagnetic treatment of water used in those water systems that use plastic pipe, which as well as metal formed lime.
If, after electromagnetic treatment of water are still visible limescale deposits, they represent a soft powder, which is effortlessly removed from the working surface, while the plaque formed by the untreated water is a rigid crust, which is removed with household appliances and surfaces was possible only when using acid-containing detergents.
Today, electromagnetic water treatment is widely used in international practice in residential, commercial and industrial facilities, repeatedly increasing the service life is absolutely the whole machinery is in contact with water, reducing energy consumption in boilers, washing machines and dishwashers, reducing turnaround time, reducing the amount of detergent. However, the installation of such devices to protect equipment allows you to completely abandon the regular cleaning of boilers and heating elements, and protection from scale operates continuously, which reduces fuel consumption, the cost of pumping coolant, etc. The chemical composition of water remains unchanged.
Unlike permanent magnets, electric transformers do not require tapping into the system - the device is attached to the wall and connects to the network and wire emitters are just winding up on the inlet pipe.
"The only thing that currently prevents the wide adoption of this technology in our country, it's ingrained notions of scale as a minor problem and a clear underestimation of the economic component of this phenomenon on the power system", - said Julia Belsky.
"Residents of cottage communities believe that the plastic pipes in water systems eliminate them from all problems. While nobody thinks that in the next 2-3 years the level of lime in appliances and systems, hot water and heating cottage towns, there are over 10 years can be a critical ", - said Victor Kovalenko.
