Water from a well is often distinguished by the presence of various trace elements and impurities that do not affect its taste characteristics. The presence of iron in the composition can be said in the case of an intense metallic taste. It is undesirable to consume such water, as well as to use it for economic purposes. It can ruin things and adversely affect plants. At the same time, you should not look for another way to get water, since it can be made suitable for drinking with the help of purification.
Where does the iron come from
This mineral is quite common, the cause of its appearance in the liquid are erosion processes in the soil layers. Particles of the substance are not visible to the naked eye, and if you install filters to soften water, you can get a purified, healthy product.
The mineral can be contained in the composition in a different state: suspended, dissolved, and others. Each of them can harm both humans and animals. Despite the fact that colloidal iron has healing properties, the water containing it is unsuitable for regular use.
Varieties
A water filter for giving from iron in the form of a jug is the most common. It consists of a housing and a cartridge, its work is carried out using membranes that retain even the smallest joints. It is extremely easy to use, but not without drawbacks, among which it is worth noting the time allotted for the passage of fluid through the cartridge, and a small volume of the jug, which holds no more than two liters.
Water purification in the country, subject to the availability of a pumping station, can be carried out by a reverse osmosis filter . Its mechanism is based on catalytic compounds. It is characterized by high productivity and efficiency, while the mineral is discharged into the drainage, and does not accumulate in the membranes, which increases the period of use of the cartridge.
In the mechanism of ion exchange lies a special resin, which provides the replacement of iron with sodium compounds. Sufficient efficiency is noted under the condition of a small amount of impurities, but during operation the mineral accumulates on the cleaning elements, begins to oxidize and causes a decrease in productivity.
The principle of oxidation has also found its application as a method of water purification. The mechanism of action is based on manganese, which oxidizes iron, and subsequently the compound is filtered off. Among the negative aspects of the technique, it is worth noting the possibility of manganese entering the purified water.
How to choose
A high-quality filter for water to give iron, in addition to purification from the compounds of this mineral, must capture other impurities, a large number of which differ from sources such as a well and a well. When choosing, you need to pay attention to the type of filtration used and the possible intensity of membrane operation. High iron content is a frequent problem, the main reason for its occurrence is the passage of precipitation through glandular ore. To prevent such troubles in the process of creating a well in a summer cottage, it is necessary to strictly observe all the rules.
Harmful water with iron content
Water from a well with a high concentration of a mineral acquires a yellowish tint and metallic taste. Its use is harmful to health. Tiles and plumbing devices also suffer: rusty, hard-to-remove streaks form on them. With excessive accumulation in the tissues and internal organs, allergic reactions occur, the likelihood of developing cardiovascular diseases increases, the body's protective functions decrease and the liver is damaged.
Filters for softening water make the liquid drinkable. They can have various fillers and structural design, but the functions remain the same. The form of glandular compounds affects the technique used. Before choosing the appropriate option, it is necessary to take water samples to determine the concentration. In another case, there is a possibility that the device will not cope with the amount of mineral and will fail.
Mechanical method
Mechanical purification of water in the country allows to eliminate trivalent compounds. To increase the life of the device and prevent intense clogging of the device, it should be replaced regularly or have the ability to flush.
Devices of this type are classified into several categories, depending on the fraction of particles and the quality of cleaning. Most often they are mounted in the inlet of the pipeline. Filtering parts can have cartridges for water purification from iron or a filling, mesh and disk design. The first option requires periodic replacement, others should be cleaned under running water. Aeration systems are effective at high concentrations of iron, their mechanism of action is based on oxygen treatment, subsequently the particles settle, and their content in the liquid decreases. But such systems require the installation of expensive equipment.
rules
Devices require compliance with a certain ambient temperature regime, so they are installed in rooms with room temperature. At negative values, the water purification mechanism becomes ineffective.
Iron removal filters should remove approximately 200 liters of contaminated fluid weekly. When reducing the amount of fluid passed through, the device will become unusable due to caking of the filling components.
Oxidation and Aeration
A variety of methods are used to purify water produced from downhole sources. The use of potassium permanganate is highly effective, but such a technique negatively affects the environmental situation and human health. The best option, without such negative sides, is a water filter for giving from iron.
For the aeration method of purifying water from a well installation, an addition in the form of spray devices is required.
Purification by active oxidizing agents is carried out in the presence of a divalent mineral. Chlorination of the liquid has become widespread, but it is not able to compete with a method such as ozonation. But the latter option contributes to high energy consumption. It is also worth noting the need for careful observance of safety regulations and rules of use, since poisonous gas is formed when the concentration is exceeded.
The oxidation technique can be applied in the presence of iron of certain fractions and forms. Chemical reactions develop inactive when using ambient air during the oxidation process. High-power pumps for air supply and volumetric tanks are required, therefore such a deferrization unit is common in industry and allows the disinfection of water at the same time.
In the process of oxidation, particles of insoluble glandular compounds acquire a minimum size. They precipitate for a long time, so the process is often accelerated by special coagulants. They provide a quick connection of the elements; subsequently, the simplest water filter removes large particles to give iron from the filler in the form of sand.
Bacteria
If the mineral concentration exceeds 1 mg per 1 liter of water, intensive multiplication of iron bacteria begins. The activity of this process depends on the presence of oxygen and water temperature. A hot water pipe is an ideal place for bacteria to develop. For their growth on the inner surface, two to three months is enough. They lead to the rapid failure of automation and plumbing devices. Failure of taps occurs due to sludge settling, which hardens upon heating and contributes to the development of corrosive phenomena when it enters metal parts.
