Water iron removal filter with a special filler is one of the most efficient units of this type. This design has become widespread both among ordinary consumers and in production. Due to it, it is possible to obtain the desired result, subject to overall high performance and relatively low costs.
Dignity
There are many reasons justifying the prevalence of such a device. Even inexpensive options can treat large volumes of liquid. At the same time, a set of units based on membrane technology with a similar performance is characterized by high cost and complexity of installation. Equipment that uses replaceable cartridges requires a significant investment during operation.
The water iron removal filter is completelyan automated device that performs regeneration and cleaning, controls the level of the solution and other nuances.
The basis of this equipment is ion-exchange technologies, that is, specialized resins - the main part of the backfill is subject to repeated regeneration. The average service life is 7-9 years, it can be extended if the manufacturer's recommendations are fully observed.
The filter is able to simultaneously perform several functions and purify water from mechanical impurities and hardness s alts.
Design
For the manufacture of the case, various materials are used, most often you can find composite and plastic options. 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 influences, corrosion processes and oxidation.
The lower part of the central pipe is supplied to the distribution unit, and the upper part to the control unit. The task of this component of the filter system is to divert the liquid in the direction that is required to comply with the technology. Such elements of modern devices are made of high-quality plastic, which is resistant to mechanical damage and corrosion processes.
Distributor's name is on the distribution bottom part. Fluid passes through this part when it is supplied or withdrawn, regardless of direction andquantities. On the body of the device there are many holes to ensure the full use 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.
Do-it-yourself filter for iron removal of water
Homemade design is sometimes used in country houses, in which the well is the main source of water for various needs. Such a system, in addition to its basic functions, is able to eliminate pathogens. A duralumin container with a capacity of 100 liters of liquid acts as the main part of the structure. Two nozzles provide control of the water in the tank, these elements communicate with each other using a silicone hose. The pump from the tank pumps water that has already been cleaned.
Water iron removal filter: features
A characteristic feature of the devices is a hemispherical shape on both sides of the body, ensuring ease of use and established performance. Thanks to a specialized pad, stability is formed when in a vertical position, it is fixed on the outer plane of the bottom. Standard devices most often have one neck for supplying and withdrawing liquid, as well as for filling composite components. It has a threaded connection for easy fastening of external elements.
In the case of 24-hour use, there may be difficulties due tofor systematic flushing backfill. During this period, it is not recommended to use water until the characteristics of the granular substances are restored. This problem can be solved if additional filters are installed in parallel to remove iron from the water from the well. Feedback from people who have purchased such devices is mostly positive. They note a significant improvement in water quality.
Filler value
The distributor is surrounded by additional backfill, which is designed to clean the liquid from mechanical foreign particles and its uniform distribution. As this mixture, a combination of gravel, sand and other materials with a granular structure can be used. The backfill is systematically cleaned using special flushing modes, and it does not need to be removed. Also, due to them, the required density is formed for the high-quality performance of all functions.
The filter for deferrization of water from the well performs 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, and overall performance. That is, without the appropriate knowledge and experience, it is difficult to correctly compose the mixture.
For the calculation, the minimum and maximum pressure levels, purification technology, tank dimensions, the degree of purification required, and the composition of the water are of particular importance. It is possible to use various backfills, they can be both multicomponent and consistfrom one material. Some situations require the location in separate layers of backfills with different compositions. Changes in water composition during snowmelt and floods should be taken into account during calculations.
Monitoring and control unit
With the help of this device, water softening and iron removal filters perform automatic work. Therefore, it is difficult to imagine any modern version without such equipment, as it allows you to save the user from many laborious operations.
The BCU always has a valve system equipped with a mechanical, electronic or hydraulic drive, or a combination of them. It ensures that water is directed to the installed flow circuit when removing foreign matter and flushing.
Signals from external sensors go to the electronic unit, which has specialized software. 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 solution tank, fluid outlet and fluid inlet connections.
The simplest water iron removal filters with a high iron content are distinguished by the placement of LCD screens and other monitors in the body of the BCU itself. More modern systems have remote units that provide a location that is convenient for users. They display executable programs and the operation of the device in real time. They also allow you to make changesinto the system and quickly reconfigure the parameters.
Principle of BCU operation
Performance of the main tasks is based on the following algorithms:
- Accounting for water volume consumption defined by users. A special device that automatically calculates the amount of water used is used to read the corresponding readings.
- Set time slots. Such systems are based on a timer that starts the regeneration or flushing process at specific time intervals.
Choice
Reagent-free filters for water iron removal are selected depending on a specific reservoir or well used as a water source. Iron in lakes and rivers is presented in the form of colloidal compositions containing mineral elements. The presence of sulfides in places rich in acidic components is noted. Also, in the presence of a high level of oxygen in surface-type sources, a large amount of it is provided in the water. Iron takes on a trivalent form due to intense oxidative processes.
A high-quality and reliable device purifies water precisely from those particles that must be removed. The liquid may contain iron in various forms. Therefore, a competent selection of a cleaning system with preliminary bacteriological analyzes is required. The calculation of the water deironing filter is carried out depending on the results obtained. They also determine the quality of the equipment and the optimal operating modes formost efficient.
Composition of water
For artesian wells, the presence of hydroxide is characteristic due to the lack of free entry of oxygen in depth. This chemical compound is highly stable when the acidity threshold is exceeded. The content of calcium s alts is also often noted. Such substances contribute to the oxidation of iron upon contact with oxygen and turn water into a cloudy liquid with a specific taste and hue. The hydroxide after coagulation is modified and precipitates as a dark precipitate.
The presence of "organic iron" is also possible in water from wells. It is presented in the form of slippery deposits that form in the bends of pipes and the entire water supply system.
