Os melhores sistemas de filtragem de água para casas e apartamentos particulares, qual comprar?

The search for the optimal engineering solution for organizing a local system is complicated by the variety of offers of specialized manufacturers. Advertising campaigns emphasize the advantages, but mask the disadvantages of individual models. With the help of a detailed study of specialized products, you can find out which option will really be better.

The main contaminants of tap water and water from a well in an apartment and a private house

Current legislation defines special sanitary and hygienic restrictions. This means that the preliminary preparation should remove all harmful contaminants. But in practice, not all incoming water is suitable for drinking. Unpleasant odor may indicate the presence of residual chlorine, allowed by the norms of SanPiN 2.1.4.1074-01. Natural wear and tear of pipes provokes contamination of the liquid with rust.

The situation is more complicated when connecting to an individual source. The lack of centralized water treatment implies a relatively high level of contamination. However, by natural filtration, a deep well provides good protection from domestic, industrial and other wastes of human activity. In this case, you will have to fight with impurities leached from rocks:

• calcium and magnesium salts;
• divalent iron;
• mechanical contaminants.

To exclude erroneous decisions, check the actual composition of impurities by laboratory analysis. When placing an order, you can include more than 50 control items in the corresponding list. The information obtained will help to correctly select an effective water filtration system for a private house or apartment.

Separately, it is necessary to study the fight against limescale. According to sanitary norms, too high a concentration of contaminants is allowed – 7 °J. It is harmless to humans, but poses a danger to engineering communications and household appliances. Persistent calcium deposits damage expensive equipment, provoke accidents, increase gas and electricity consumption. Corresponding problems are eliminated by preventive protective measures.

Rating of the best main water filtration systems

If quality purification is organized at the inlet, the subsequent stages of treatment may not be necessary. For this part of the water filtration system for a country house or apartment, a sufficiently high performance is required. The value of this parameter is determined by the average flow rate, taking into account the peak increase in consumption at maximum load.

Manufacturers offer ready-made engineering solutions that can be applied in practice. Let’s consider 3 groups of filters of the corresponding target purpose.

Hollow fiber

Products of this category are comparable in quality of water treatment with reverse osmosis, so they are quite suitable for the finishing stage of purification. But hollow fiber membranes process the liquid much faster (from 900 l/hour), so they are suitable for installation in the main sections of the water supply system. The fineness of filtration in this case is from 0.1 to 0.01 microns. Such a barrier does not allow microbes and viruses to pass through.

In the simplest version, disposable working blocks with a typical resource of 8-10 thousand liters are produced. They are replaced with new ones after contamination, like conventional cartridges. Critical deterioration of the operable state is recorded by a decrease in head. For an objective assessment of this control parameter, you can add a pressure gauge to the equipment of the system.

Flushable analogs are more expensive, but such an investment is justified by a significant increase in resource – up to 450-500 thousand liters. With a correct calculation of needs, it is possible to choose a module that will keep working condition for several years.

For the installation of membranes, manufacturers offer specialized enclosures. The most durable are models made of stainless steel. They are equipped in the standard version with a spigot for connecting the drain. Calcium deposits accumulated in the membrane are removed by soaking in a weak acid solution. Detailed maintenance recommendations can be found in the operating instructions.

Electromagnetic

In the section with an overview of impurities, it is noted that salts at high levels of hardness are harmless to humans. Calcium, magnesium, mineral compounds are essential components of a healthy diet. On the other hand, even small concentrations of the respective impurities are very dangerous for the heating elements.

The above-mentioned problem is solved with the help of a strong electromagnetic field, which transforms the hardness salts. The treated impurities lose their ability to transform into scale, but the liquid retains its healthy components and pleasant taste.

All devices of the corresponding purpose are produced with the use of a typical electrotechnical scheme.

To choose the best option, in addition to the price, the following control parameters are checked – the maximum values for serial models of the household category:

• power consumption – 20 W;
• frequency of the signal produced by the generator – from 1 to 50 kHz;
• rigidity at which the design efficiency of treatment is maintained – 25°J;
• protection range along the length of the pipeline in both directions from the coil – 2 thousand meters;
• service life – 25 years.

The characteristic advantage of the system is simple connection without tapping into the pipeline. Electromagnetic field does not increase hydrodynamic resistance. Its parameters are maintained in automatic mode without careful control and special user settings.

Mechanical

This category includes a wide range of barriers that are capable of trapping impurities from 0.8-1 microns:

• string;
• mesh;
• porous – made of titanium chips, polymer foams;
• disk;
• bagged;
• backfill, etc.

Models with connection sizes corresponding to the parameters of typical sanitary pipes are produced. When searching for a suitable option, the following are also evaluated:

• performance;
• temperature limits;
• nominal/maximum pressure;
• working position.

Mechanical filtration of tap water in an apartment or when connected to a well is organized in stages. Purification begins with larger impurities and ends with small impurities. Hollow fiber module, for example, can be protected from rapid contamination by installing a coarse filter with the preliminary removal of particles with sizes 5-50 microns.

Rating of the best water filtration systems

After the main treatment, it is necessary to check the intermediate result by analyzing samples. If there are still harmful impurities, finish filtration of drinking water is applied according to the reverse osmosis scheme, which in an apartment or other object can be performed in the kitchen under the sink. Free space in the cabinet furniture is used for hidden placement of functional components.

Reverse osmosis system Atoll A-550m ST

Installations of this series are assembled with the use of imported components produced by reliable profile manufacturers: DuPont, Pentek and others. If the normal pressure level is maintained, up to 190 liters of clean water can be prepared per day.

Aquaphor Morion

The compactness of the equipment is provided by a high capacity (more than 370 liters / day), which allows you to put a relatively small tank. Water filtration system for apartment Aquaphor in the maximum configuration is equipped with a TDS meter, other useful options for users.

Geyser Prestige

Budget series provides high quality filtration, like other installations with reverse osmosis membranes. If you choose this option for an apartment, you will have to perform maintenance more often. Branded cartridges are cheap, but their resource does not exceed 3 thousand liters.

What water filtration system to choose and buy for a country house?

For a large residential property connected to an autonomous source, it is recommended to prepare a special project. Entrusting the relevant task to specialists will prevent errors, help to choose compatible system components.

User reviews

Igor, 28 years old, Saratov:

I bought the most affordable installation Geyser Prestige, which the seller in the store advised to choose for the apartment. Was not disappointed in the decision. For our small family (2 people) the performance is quite enough, and the cheap reverse osmosis membrane on the principle of action provides high quality cleaning.

Nikolay, 48 years old, Vyazma:

We put at home a set: mechanical filter, hollow fiber module, AquaShield. The equipment works for more than two years without complaints. Scale has disappeared. The absence of harmful impurities confirmed by laboratory testing. Especially pleased that it is not necessary to change cartridges.

Alexander, 34 years old, Tver:

To organize water filtration in the apartment for drinking, I chose an expensive model in the Aquaphor Morion series. The technique works qualitatively with a declared high level of performance. There is a built-in pump that raises the pressure to the nominal level automatically. But I have already decided on the implementation of complex purification, since the centralized supply does not suit the quality.

Draw conclusions

If you are going to buy a water filtration system for an apartment, do not count on perfect pre-cleaning. The exact choice of filter system can be made only after analyzing the water. The owner of a private house when connecting to a well, it is also necessary to analyze to solve the problem of water treatment.

It is best to contact a specialist to prepare a quality project. Some sellers offer these services free of charge as a bonus when placing an order.
