Filters for water purification from iron

The elimination of manganese and iron from water is a mandatory measure. This issue is especially relevant for owners of private houses with autonomous water supply. And in urban central networks often water has not the best quality and various impurities.

Therefore, it is important to install water deferrization filters. Such devices are called filters - iron removers (FD).

The specifics and purpose of FD

The presence of iron in water causes considerable harm to human health. Household appliances, for example, washing machines, a dishwasher and other plumbing, also suffer.

FD prices are much lower than professional counterparts. At the same time they have excellent efficiency and compact parameters. Therefore, they are optimal for use in any house and apartment.

The effect of all filters is similar. First, they oxidize water-soluble iron to insoluble conditions. And then comes mechanical filtration.

The soluble iron format is divalent. Insoluble - trivalent. The substance in the first format is extremely difficult to remove. Reverse osmosis devices are capable of this only when the iron concentration is low. For this reason, for high-quality water purification, its oxidation is first carried out. So the iron goes into the second format.

Such a transition can be implemented in two ways:

1. Reagent. Chemical elements are used here.
2. Non-reagent. They do not apply here.

According to these methods, FD are divided into two categories.

1. Reagent FOs act with special oxidizing agents: manganese, chlorine and ozone.
2. Reagentless FDs oxidize iron using oxygen. They artificially fill them with water. It dissolves in it and transforms iron into a format convenient for filtration.

About types of FD

Reagent-free devices can be filled and aeration. The first are sealed cylinders. They are filled with a special substrate. Its function is absorption. Usually it is an aluminosilicate sorbent. He is a catalyst for oxidation.

Water flows into the device, passes through a sorbent, and is filled with oxygen. And then iron is oxidized and becomes trivalent. It is converted to normal sediment and remains in the cleaning layer.
The main disadvantage of such devices: in the process of working backfill is generated. We have to constantly regenerate it.

Depending on the device, this process is carried out automatically or mechanically. In general, these FDs are optimally mounted in cottages and in private homes. In Russia, special geyser models are in great demand.

Aeration filters artificially fill the water with oxygen. So iron is quickly converted into a convenient form for mechanical cleaning.
Such FD can be pressure and non-pressure. Water in non-pressure models follows the functional capacity through a network of nozzles. They spray the incoming water stream. Drops fly to the bottom of the container. And during this time, water is enriched with oxygen. Iron is oxidized.

In a pressure device, air flows into the tank under high pressure. Its discharge is the merit of the automatic compressor. Iron turns into the desired format. It is taken from water. This is a merit of mechanical filters of aeration equipment. Cleansing is obtained with the highest quality. Therefore, the price of such devices is solid.

Reagent devices differ from each other in the type of substance used. Today they are used less and less in everyday life. The reason is that these reagents add impurities harmful to humans to water. But in the industrial environment they are actively involved to this day.

In order for FD to function effectively, you need to follow three key rules:

1. Regularly restore the cleaning agent as needed. It can be backfill, cationic resin, etc.
2. The resulting substrate is very harmful. Therefore, your water supply network must have a minimum pressure of 3 atm. If the parameter at the inlet is lower, the water is treated worse.
3. Do not violate the temperature regime. Even if the appliance freezes for a moment, it can seriously break down.

The principles of choosing FD for the home

In order to choose a suitable DO for the home, you must first set the composition of water. For this, water samples are taken. And their laboratory studies are being conducted. As a result of examinations, accurate data on all substances that are dissolved in water are displayed.

It is required to focus on a high concentration of iron and other indicators that deviated from the standards. This will allow you to choose the most effective device and guarantee effective water purification.

When water is being prepared, many criteria are important:

1. Filter efficiency.
2. Type of cleaning downloads.
3. The principle of operation of the compressor.
4. Case parameters.

When appliances are mounted on residential objects, the following factors come to the fore:

1. Compactness of parameters.
2. Reasonable prices of filters and their installation.
3. Optimum costs for working with devices and their maintenance.

For proper installation, it is better to contact specialists. They will help to implement a project of varying complexity.

The lineup

It is important to understand the FD market yourself, to know which models and brands occupy leading positions. The following is a list of such models:

1. "Standard". There are reagent and reagent versions. The first is EMS F. The second is EMS X. They comprehensively and efficiently clean well water. They have economical prices.
2. "Ekomaster." There are reagent devices EMS: IM and MT, and MX. The latter are multifunctional. There are aeration models: AR and AT.
3. Universal technology "Ecodar Pro". Carries out high-quality water purification without reagents.
4. Ekomaster "Doublet". The device reduces the iron content, eliminates turbidity and nasty smells of water.
5. Geyser AquaShif 1044 \ 5Mn. Reagent-free device. Price: 18 000 - 19 000 rub. Case material - stainless steel. The color is silver. Processing Parameter: 1.2 cc m / h The filter medium is ion exchange resin.
6. Pentair FBI 50-09T. 25 000 rub. The case is metal. The color is blue. The working parameter is 0.9 m3 / h. The cleaning agent is aluminosilicate. It contains manganese and silicon oxide.

There is no budget option to remove iron from water.

1. Upholding. This takes time and fresh air. Water from the well is poured into the barrel.
2. Distillation. Here the simplest model of FD will fit.
3. Filter jugs. They are mobile. They can not be connected to current and utility networks. It is important to correctly resolve the issue with a suitable cartridge.

Criteria for choosing the Federal District for giving

In the country, well water is most often used. And when choosing a federal law here they rely on such criteria:

1. Data on the composition of water.
2. Often there is a need to use several models simultaneously, because various impurities come across.
3. Studying filter parameters and their features.
4. Collection of information on all existing needs and limits from manufacturers of individual elements in water treatment technology.

Summary

Often these criteria are not enough to make the right decision. In this matter, do not be negligent. After all, the quality of water affects your health. Therefore, professionals are often attracted in order not to make a mistake in choosing and to deliver a reliable and effective FD.
