Flow-through main for water: overview, types, characteristics, features of choice and reviews
A variety of filter types can be used to clean the water entering the house or apartment. Often they are used separately, but sometimes they are installed in a complex. There are both conventional filters installed after the crane, and the main. The main feature of the last type of devices is that they cut directly into the pipe or are hung on it.
What are the main water filters
Devices of this variety usually consist of two main parts:
- a water-purifying membrane, a mesh, a cartridge, etc.
The main flow filter for water can be plastic or metal. The material of the first variety is usually used for manufacturing reagent devices. This is due, first of all, to the low chemical activity of the plastic. Cases of mechanical filters are often made of metal.
Types of trunk devices according to the principle of operation
On this basis, all filters are classified into three main groups:
All these types of devices can efficiently purify water, but are used to remove impurities of different types.
Filter for water flowing main mechanical cleaning: features of use
In the devices of this group, the cleaning is done using a grid. This is the way the models are designed to remove organic impurities and solid particles from the water. They are called filters of rough cleaning and are most often installed in country houses. However, sometimes they are used in apartments.
A flow-through main for mechanical water can also be supplemented not with a grid, but with special perforated, polypropylene, winding, corrugated, etc. cartridges. Devices of this type remove contaminants from water more efficiently than mesh, but also cost more. They are called fine filters.
In addition, there are even more complex models of mechanical devices. Filtration in such structures is carried out through a special perforated membrane. The holes in it are so small that only water molecules can pass through them. At the same time, all impurities are retained.
Cartridges of chemical filters are filled with different kinds of reagents. In inexpensive models of this type, it is usually necessary to cover special polyphosphate crystals. More advanced and productive ion-exchange devices are columns filled with a special resin containing a large amount of sodium, and equipped with a control panel. Chemical main filters are used mainly to remove salts from the water, increasing its hardness.
A flow-through filter for water of this variety is also used to remove salts. The principle of operation of the devices of this group is quite simple. Under the influence of the magnetic field, the salt particles change their shape to a needle-like one, as a result of which they lose the ability to adhere to the surface, forming a scale. At the same time, when passing through pipes and parts of the construction of household appliances, they also gradually scrape off the already existing calcium deposits.
Electrical devices of this type differ from conventional magnetic ones in that they affect salts at ultrahigh frequencies. It is not necessary to cut such models directly into the pipe. Most often they simply hang on the highway with the help of special fasteners.
Species by purpose
Use a main flow filter for water can from contamination:
- "Mechanical" (particles of clay, sand, organic, etc.);
- biological (bacteria, fungi).
In a separate group are allocated and softeners. They are intended primarily to protect all kinds of household appliances and units from premature failure.
Types of the number of steps
By what other characteristics can a filter for water flow trunk be selected? "Which is better to buy?" - The answer to this question depends, in part, on what kind of pollution is required to be removed. Individual filters can perform only one function - to clean it from dirt, salts or microbes. However, it often happens that the water in the well or well contains a large number of impurities of different types. In this case, multi-stage devices are used. Their design includes several filter elements of different types.
In urban apartments, ideal water purification systems are usually performed by reverse osmosis systems. The water after such filters is almost distilled. For various kinds of household needs, it fits perfectly. However, of course, it can not be used as a drinking water. To correct the situation, in addition to filters and membranes, special mineralizers are additionally included in such systems.
In country houses, large prefabricated systems are often installed, which may include models of coarse and fine cleaning, deironing agents, ion exchange columns, ultraviolet disinfectors, etc.
Filter for water flowing main: which is better to choose
When buying a reverse osmosis system for an apartment in the first place, you should pay attention to the volume of the storage tank and the brand. Dependence on these factors depends on the service life and productivity, and hence the convenience in using the model.
On the pipes in the apartments are often mounted and electromagnetic water softening filters. When buying such equipment, it is worth paying attention first of all to its capacity. This parameter should be such that the appliance provides softening of all water used in the apartment. Very good, such a filter for water flow trunk for the country.
For a large residential suburban home, the water filter is usually chosen based on the results of laboratory tests. On a mandatory basis, only coarse devices are installed on the highway. After all, sand and silt impurities are present in water from virtually all wells and wells. In this case, usually a filter for water is used, a flow-through main washer. In such models, the grid can be removed and cleaned or changed to a new one.
As a softener for a large cottage, it is better to purchase an ion-exchange column. Also it is necessary to put in such a house an ultraviolet disinfectant.
Reviews about filters from different manufacturers
Equipment designed for water purification is now produced by many companies. And in most cases in the market you can find only quite high-quality filters. Good reviews of consumers deserve, for example, brand models:
- "Geyser". These devices are praised primarily for high performance, thoughtful cleaning technology and ease of installation. If desired, you can buy a water filter for flowing main "Geyser" for some specific purpose or complex.
- Aqua Filter. Filters of this manufacturer received good reviews for the possibility of processing a large amount of water and not too high cost.
- Atoll. The popularity of the devices of this manufacturer is due primarily to compactness, small price and excellent cleaning quality.
Of course, in the domestic market filters are being implemented and other good brands. For example, the filter for water flowing the main "Leroy Merlin", which is convenient for use and has a long service life, deserved good reviews. Also, the models of "Akvashchit", "Galaxy" and some others enjoy an excellent reputation among domestic property owners. All these devices have a durable absolutely hermetic casing (and therefore, do not leak), they qualitatively process water and are sufficiently productive.
