How filters for iron removal of water are arranged and work

An urban or autonomous water supply system cannot be ideal without installing additional elements in the form of filters. Full purification of water from iron and manganese occurs only with the use of special equipment. Even if the liquid is obtained from a well near the house, the metal content is still increased in it. Iron removal filters are the only solution that can improve the quality of the drinking resource.

Purpose and use of cleaners

The increased iron content in water leads to its concentration in the human body. This can be suspected by symptoms such as a rash, itching of the skin. The kidneys and liver also begin to suffer. High iron content in household appliances such as washing machines or dishwashers quickly builds up scale and corrosion.

An iron remover is a filter that can remove metal molecules before they enter appliances or the cooking process. Household filters are efficient, relatively inexpensive and easier to maintain than professional units. However, they are in no way inferior to industrial solutions. They can be used both in apartments and in private houses.

The principle of operation is similar even for different species: first, the water entering the filter is oxidized, as a result of which the iron becomes insoluble, then the metal is retained mechanically. This process can be performed by 2 methods - with and without reagents. According to this principle, deferrization filters are divided into 2 types.

The following are used as reagents for removing metals: ozone, chlorine, manganese. In equipment without reagents, oxygen exposure is used. Molecules saturate water by acting on ferrous iron, as a result of which it is converted into an insoluble form.

Features of different types of cleaners

Reagent-free filters are divided into 2 types: filling filters with aluminosilicate sorbent or resin and aeration filters. In apartments, main water filters are often installed, in which there is a cartridge for chemical and mechanical filtration. These devices differ in size and performance. The owner of the home independently chooses the type of equipment, monitors its serviceability and changes cartridges.

Multi-stage filters are the most effective technique for removing iron from liquid:

• removal of up to 99% of impurities when passing through different stages of purification;
• complex fight against foreign molecules;
• separate cartridge for different types of cleaning;
• long-term operation of one replaceable filter;
• high performance.

The only drawback of such an installation is the complexity of installation and large dimensions. Not every apartment has a place to integrate such technology.

Inline multi-stage filters are the most efficient and costly solution. However, in the absence of space or other factors, more compact options can be shaved.

Jugs and tap nozzles

An expensive staging unit can be replaced with an ion exchange resin filter cartridge. These accessories are designed for one purpose - removing all metals from water. As the active components are used up, they can be replaced. The pluses of nozzles include:

• low cost;
• small size - nozzles rarely exceed 10 cm in diameter;
• ease of installation and use;
• replacement without the involvement of specialists - following the instructions will help to avoid mistakes.

It is best to use such elements in apartments with a low to medium metal content in the water. For deferrization of water in the cottage, it is better to install a large filter.

Jugs with a filter are used for additional purification of water in which a high content of metals is found. However, they cannot be considered a complete system for removing iron from liquid. It is also important to consider the type of cartridge installed in the jug. The user should remember that these accessories are designed primarily for mechanical filtration.

Equipment selection criteria

When buying an iron remover, the following parameters must be taken into account:

• the degree of water pollution - the higher the metal content, the more powerful the installation is needed, the nozzles for the faucets are unable to clean the liquid in which iron is contained hundreds of times more than the norm;
• equipment performance - for a large house or family of 10 people, more powerful filters are required;
• dimensions are one of the main parameters, because not every apartment can be equipped with a powerful household cleaning system;
• possibility of independent replacement of sorbents and cartridges.

Many companies involved in the installation of large household filters provide advice and help you choose the best solution.

Features of equipment installation

Before installing the equipment, you must study the instructions, read the manufacturer's recommendations. Then the elements of the system are taken out. It is necessary to check the housing and make sure that there are no filter cartridges.

It is necessary to carry out the installation using a plumb line - the base of the device should stand exactly in the chosen place. Beforehand, a flat sheet of material is placed on the floor at the installation site. Next, perform the following steps:

1. Install the main elements of the equipment, check the control unit. There should be free access to the control unit.
2. Following the instructions, install the distributor mechanism, connect the pipe. It should be just above the end of the case.
3. Put a protective cap on the pipe to prevent the penetration of reagents.
4. Fill the filter a quarter with water. Then, using a funnel, add the materials from the kit. The filter medium should occupy no more than half of the body.
5. Remove the protective cover, treat the upper cut of the pipe with silicone grease. Put the valve on the distribution hose and wrap it up.

This circuit is used to install a large size de-ironing filter. However, the steps may differ depending on the type of equipment.

Features of the use of iron-removing filters

The purifier does not require complex maintenance to keep it working and not breaking down. However, special attention must be paid to the quality of replacement cartridges. They need to be constantly monitored. Pay attention to the instructions for the equipment and recommendations for replacing filter elements. Typically, replacement times range from 6 to 24 months.

It is important to remember: the iron removal kit should not freeze, therefore it is installed in a room where the temperature does not drop below + 1-5 degrees Celsius. For the high-quality operation of the iron remover, the pressure in the water supply system must be at least 3 atmospheres.
