A filter of deironing water to purify water from iron and impurities

A water deironing filter having a special filler is one of the most efficient units of this kind. This design has become widespread both among ordinary consumers and in production. Due to it, it is possible to obtain the desired result under the condition of overall high productivity and relatively low costs.


There are many reasons for the prevalence of such a device. Even inexpensive options can purify a large volume of liquid. In this case, a set of units based on a membrane technology with similar performance is characterized by high cost and complexity of installation. The equipment using replaceable cartridges, during the operation, requires significant investments.

The water deironing filter is a fully automated device that performs regeneration and cleaning, controlling the level of the solution and other nuances.

The basis of this equipment is represented by ion-exchange technologies, that is, specialized resins - most of the backfill is subject to repeated regeneration. The average operating period is 7-9 years, it can be increased with full compliance with the manufacturer's recommendations.

The filter is capable of simultaneously performing several functions and cleaning water from impurities of mechanical type and hardness salts.


Various materials are used for making the case, most often one can find composite and plastic versions. Stainless steel is used much less often, due to the rather large mass and cost. Thanks to the materials used, the water deironing filter Acquires strength and resistance to external and temperature effects, corrosive processes and oxidation.

The lower part of the central pipe is fed to the distribution unit, and the upper part to the control unit. The task of this component of the filtering system is to divert the fluid in the direction that is required to match the technology. Similar elements of modern devices are made of high-quality plastic, characterized by resistance to mechanical damage and corrosive processes.

The distributor name has a distributing lower part. The liquid passes through this part when it is fed or fenced, regardless of direction and quantity. On the body of the device, there are a plurality of apertures to ensure the full application of the working volume of the filter, in particular its lower part. It is possible to obtain such properties only if there are no contaminants that can interfere with the movement of the liquid.

Filter for deironing water by hand

Homemade construction is sometimes used in country houses where the well is the main source of water for various needs. Such a system, in addition to its basic functions, is capable of eliminating pathogenic microorganisms. The duralumin container, containing 100 liters of liquid, acts as the main part of the structure. The two nozzles provide control of the water in the tank, these elements communicate with each other using a silicone hose. Pump from the tank pumped water, has already been cleared.

Water deironing filter: features

A characteristic feature of the devices is a hemispherical shape on both sides of the housing, which provides convenience of use and the established characteristics. Thanks to a specialized pad, stability is formed when in the vertical position, it is fixed on the outer plane of the bottom. Standard instruments most often have one neck for supply and intake of liquid, as well as for backfilling of composite components. It has a threaded connection for easy fixing of external elements.

In the case of round-the-clock use, there may be difficulties due to systematic washing of the backfill. In this period it is not recommended to use water until the characteristics of granular substances are restored. This problem can be solved if additional filters are installed in parallel for deironing water from the well. Reviews of people who have purchased such devices are mostly positive. They marked a significant improvement in water quality.

The value of the filler

The distributor is surrounded by an additional backfill, which is designed to purify the fluid from mechanical foreign particles and to distribute it evenly. As a given mixture, a combination of gravel, sand and other materials with a granular structure can be used. Backfilling is systematically cleaned by means of special washing modes, and it does not need to be removed. Also, due to them, the required density is formed for high-quality execution of all functions.

The filter for deironing water from the well carries out its tasks, depending on the parameters of the main backfill. A competent choice of composition determines the duration of operation, purification from certain types of impurities, overall productivity. That is, without the availability of relevant knowledge and experience, it is difficult to properly form a mixture.

For calculation, the minimum and maximum pressure levels, purification technology, tank dimensions, the degree of purification required, the composition of water are of particular importance. It is possible to use different backfill, they can be either multi-component or consist of one material. Some situations require the placement in separate layers of backfill with a different composition. Changes in the composition of water during the melting of snow and floods must be taken into account during the calculations.

Control and management unit

With the help of this device, filters for softening and de-ironing water are automatically operated. Therefore, it is difficult to imagine any modern variant without such equipment, since it allows to save the user from many laborious operations.

In the BKU there is always a system of valves with equipment in the form of a mechanical, electronic or hydraulic drive, or with their combination. It provides the direction of water in the installed working circuit with the removal of foreign particles and washing.

In the electronic unit, which has specialized software, there are signals from external sensors. After setting the block to the desired algorithm, it starts sending control signals to the nodes of the valve system.

There are also external connections for supplying the tank with the solution, connecting the outlet and the inlet of the liquid.

The simplest deironing filters for water with a high iron content are distinguished by the placement of LCD screens and other monitors in the body of the BKU itself. More modern systems have remote units that provide on-site location, convenient for users. They display executable programs and the operation of the device in real time. They also allow you to make changes to the system and quickly reconfigure the settings.

BKU operation principle

The main tasks are based on the following algorithms:

  • Accounting for the consumption of water volume determined by users. A special device that automatically calculates wasted water is used to read the corresponding readings.
  • Specified time intervals. Such systems are based on a timer that triggers a regeneration or flushing process at specific time intervals.


Reagent filters for deironing water are selected depending on a particular pond or well used as a source of water. Iron in lakes and rivers is represented in the form of colloidal compositions with the content of mineral elements. The presence of sulphides in places rich in acidic components is noted. Also, in the presence of a large level of oxygen in the sources of the surface type, it is provided with a large amount in the water. Iron acquires a trivalent form due to intense oxidation processes.

A high-quality and reliable device cleans water precisely of those particles that must be removed. The liquid may contain iron having various shapes. Therefore, a competent selection of a purification system with preliminary bacteriological analysis is required. The calculation of the deironing filter of water is carried out depending on the results obtained. They also determine the quality of the equipment and the optimal operating modes for maximum efficiency.

Composition of water

Artesian wells are characterized by the presence of hydroxide due to the lack of free entry of oxygen in the depth. This chemical compound is highly resistant when the acidity threshold is exceeded. The content of calcium salts is also often noted. Such substances promote the oxidation of iron in contact with oxygen and convert water into a turbid liquid with a specific taste and tint. Hydroxide after coagulation is modified and falls out as a dark precipitate.

In water from wells, the presence of "organic iron" is also possible. It is represented in the form of slippery deposits formed in the bends of pipes and the entire water supply system.
