Water purification for a private house - device description Systems for water purification in a country house - the best filtering devices

The correct selection of a set of technological equipment will be imply not just a reasonable level of financial spending. Thorough preparation will help to optimize the water purification system in a private house, taking into account the peculiarities of operation. For the correct implementation of the project, you will need the information that is presented in this article.

Individual sources are most often used for water supply to a country house. Such a solution will make it possible to independently control the consumer parameters of the liquid.

The water, which will be free of foreign matter, can be used for cooking, drinking, washing things and even washing the car.

With a minimum degree of rigidity, household appliances and other appliances will perform their functions with the highest possible efficiency).

Major pollutants from wells and boreholes

The absence of iron will help prevent horrible rust stains in visible places. Now we are talking not only about the benefits of high-quality and purified water. It is also important to carefully study the composition of impurities.

Such information is required in order to make an accurate selection of functional components for particular equipment.

In the simplest engineering structures, like wells or a borehole in the sand, a relatively large content of such types of contaminants has been removed:

In order to separate the above components using natural filtration, usually make the source as deep as possible.

In artesian wells (depths from 70 meters and more) there is much less organic matter, as well as "traces" of human activity. But on the other hand, the concentration of such components as hydrogen sulfide, salts and iron compounds increases.

A company that deals with water purification will help to obtain accurate data and draw a conclusion, and then make a laboratory analysis and get the results. The samples are collected in a sterile container, filled up to the plug so that there is no air gap. It is advisable to do everything during floods, when there will be a maximum level of pollution, in order to get the most truthful results.

In a detailed study, the customer is given data on several dozen items. But believe me, even a simplified version with a simplified assessment by test indicator strips is not as bad as it might seem. An official document, which is certified by the signature of the contractor, will be required for professional design. This data helps to objectively monitor the effectiveness of the set of equipment you have installed.


Consideration of cleaning schemes


In addition to information on contamination at the preparation stage, it is imperative to clarify the following parameters:

  • Needs.
  • Amount of funding.
  • Availability.
  • Possibility of connecting electrical supply, as well as other engineering systems.
  • The complexity of installation work on your own.

Please note that each of the points should be studied separately. Needs, for example, can be divided into the following main groups:

  • General technical characteristics - watering a garden, a plot, washing vehicles.
  • Intra-house - cleaning, hygiene procedures, heating.
  • Cooking food.

For any of the categories, the required degree of purification should be determined.

To water the plants, it will be enough to remove large fractions of a mechanical nature from the liquid. In drinking water, all harmful impurities should be excluded in order to ensure perfect organoleptic data. Without a detailed explanation, the merits of a competent approach are understandable. Correctly formulating the most important criteria in the processing stage will help reduce the total income.

From impurities of a mechanical nature

The water purification system for a country house will consist of several stages in this position:

  • The first is the laying of a layer of granular bedding at the bottom of a well or well.

  • The next is the intake mesh to prevent pump malfunction.
  • A high-performance main filter should be made from a tank that will be completely filled with sand.
  • At other stages of the technological process, mud collectors, special cartridges, disc structures are used.

The general principle says that the ducts should be successively reduced. Finally, membranes are used with holes that are slightly larger than the water molecules.

These units should be installed in reverse osmosis kits. The cost starts from about 26,000 rubles. The main inlet filter is equipped with an automatic washing system. By the way, similar devices are used in ion exchange installations. According to the program set by the user, the solenoid valves are connected to the circuits for process cleaning.

The accumulated contamination is usually discharged into the drain. The regularity of the procedure should be organized by periods or taking into account the amount of waste fluid.

From manganese and iron

A scheme for purifying water from a well from iron should be developed after the form of impurities is taken into account:

  • Organic components should be treated with special reagents (sodium hypochlorite, ozone).
  • Colloids - they are made larger by coagulation.
  • Ferrous iron is transferred to a state in which it does not dissolve by oxidation for further retention of particles by a mechanical filtration channel.

The cost of the device is from 38,000 rubles. Complex purification from manganese and iron is performed using a special filling of a catalytic action. It will accelerate the oxidation process, extract components that have an electric charge (that is, ions) from the fluid flow. The properties of the filler (accumulative) should be restored from time to time by washing with a solution of potassium permanganate. The mode changeover will provide the customized automation unit the way you want from the solenoid valve kits.

The same water purification system for a private house is used if it is required to remove manganese impurities.

Against limescale and hardness

This is a typical system for water purification in a private house, which provides excellent protection against scale. To solve such a problem, use the following:

  • Water purification for a private house - device description Ion exchange.
  • Treatment with polyphosphates.
  • The transformation of salt impurities by a large and very strong magnetic field.

  • Membrane cleaning.

The cost will be from 57,000 rubles. When choosing a technique that suits you in all respects, you should also take into account the specific advantages and disadvantages. Polyphosphates, for example, are very inexpensive! In this case, the user will need to constantly independently control the filling of the working tank, because there will be no automation tools. Environmental pollution by water hardness will limit the scope of application.

Such reagents are usually used to protect heating boilers and washing machines. You should also exclude the possibility of their getting into the drinking water circuit.

From nitrates

Filters for water purification in a private house are extremely important if there are nitrates in the water. This term refers to the salt compounds of nitric acid, which are often used to improve the level of crop yields. Such pollution is in open water bodies, wells, sand wells.

Experts are trying to emphasize the particular danger of the sequential transformation of this type of fertilizer into nitrosamines and nitrates. The increased level of toxicity of chemical compounds can significantly worsen the state of health, even to death. According to SanPin standards, the limiting concentration of nitrates is limited to 1 liter of 45 mg. To remove such impurities, an ion exchange unit is used with filling with special macroporous granules. If the total requirements are not more than 240 liters per day, the capabilities of a typical reverse osmosis installation will be enough.

From viruses and bacteria

An incredibly high level of reliability is provided by membrane-type water purification systems. Installation of reverse osmosis basically will not allow the passage of fractions that are larger than water molecules. Microscopic organisms of all types are much larger. For this reason, while maintaining integrity, there is no barrier for consumers.

To treat large volumes of liquid (for example, pool water) use:

  • Ozonation.

  • Chlorination.
  • Ultraviolet radiation at high power.
  • Treatments with special disinfectants.

When working with a standard boil, a prolonged exposure at a high temperature is required to obtain the desired result.

Ideal layout

Typical engineering solutions have been discussed above, but some installation methods can be improved with additional tools.

So, in the presence of ferrous iron impurities in the well, such technologies are used for accelerated oxidation:

  • Spraying under the influence of pressure.
  • Non-pressure flow division into small streams.
  • Ozone injection via ejector.
  • Forced compressor aeration.

After pretreatment has been performed, the liquid is usually directed to a vessel containing catalytic bedding or activated carbon.

In an additional layer of sand, mechanical types of impurities will be retained. Reverse osmosis in terms of the degree of filtration can be compared with high-quality distillation. Still, with a long break in the operation of the equipment, secondary infection cannot be ruled out. In order for such a water purification system in a country house to perform its functions ideally, the kit should be supplemented with an ultraviolet treatment unit.

These examples will explain the need to carefully study all the critical details of an engineering design.

The ideal layout for preparing a water treatment system will exactly match your actual needs. It will not unduly increase user responsibilities during use. To make an accurate calculation of an economical type, you should take a time interval of at least 10 years.

Next, add up the costs for the following items:

  • Consumables.
  • Service.

  • Scheduled repair (replacement of blocks if necessary).

What kind of water preparation and purification system is better for a private house? When connected to a large artesian well, you can count on removing many harmful impurities through natural filtration. At the finishing stage, a jug with a built-in cartridge is used to eliminate impurities and its residues. But in such sources, the concentration of calcium fractions will be increased, which will turn into scale when heated.

Local protection of certain vehicles can be created using a polyphosphate filter.

But it will be much more convenient to use the general water purification system for a country house. Hardness salts should be delayed by the ion exchange unit. To save free space in a country house, a water purification system is used. The power of the generator is selected according to the range of action of the length of the connected pipeline.

An additional advantage of the electromagnetic "softener" is a simple wiring diagram:

  • The coil should be wound with an insulated wire (from 20 to 25 turns).

  • The main unit is placed on the floor or even fixed upright on the wall.
  • Connection of power supply from the 220 Volt network (power not exceeding 25 W).
  • The operating mode will be maintained automatically without adjustment and careful monitoring.

To prepare drinking water, a reverse osmosis kit should be added to the purification system of a country house. To saturate the liquid with good substances, a mineralizer is mounted after the membrane.


A typical complex diagram of a water treatment and water purification system consists of the following functional blocks:

  • Removal impurities of a mechanical nature.
  • Iron removal.
  • Reducing the hardness level or protecting against limescale.
  • Preparation of drinking water.

To exclude errors along with high costs, preliminary clarify the composition of impurities.
