A variety of types of filters can be used to clean the water entering the house or apartment. Often they are used separately, but sometimes they are installed in combination. There are both ordinary filters mounted after the crane, and main ones. The main feature of the devices of the latter type is that they cut directly into the pipe or are hung on it.
What are main water filters
Devices of this kind usually consist of two main parts:
- housing;
- water-purifying membranes, mesh, cartridge, etc.
The main flow-through filter housing for water can have a plastic or metal one. The material of the first variety is usually used for the manufacture of reagent devices. This is explained primarily by the low chemical activity of plastic. Mechanical filter housings 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:
- mechanical;
- ion exchange;
- magnetic.
All these types of devices can purify water quite effectively, but are used to remove various types of contaminants.
Water filter flowing main mechanical cleaning: features of use
In devices of this group, cleaning is performed using a grid. In this way, the models designed to remove organic impurities and particulate matter from water are arranged. They are called coarse filters and are most often installed in country houses. However, sometimes they are used in apartments.
The main flow-through filter for water mechanical 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 net ones, 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. All impurities are retained.
Ion exchange devices
Cartridges for chemical filters are filled with various kinds of reagents. In inexpensive models of this type, you usually need to fill in special polyphosphate crystals. More advanced and efficient 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 that increase its hardness.
Magnetic devices
The main flow filter for water of this variety is also used to remove salts. The principle of operation of devices of this group is quite simple. Under the influence of a magnetic field, particles of salts change their shape to a needle, as a result of which they lose the ability to stick to the surface, forming scale. At the same time, when passing through pipes and parts of the construction of household appliances, they also gradually clear off existing calcium deposits.
Electrical devices of this type differ from conventional magnetic devices in that they act on salts at microwave frequencies. Embed such models directly into the pipe is not necessary. Most often, they are simply hung on the highway using special fasteners.
Appointments
The main flow filter for water can be used from pollution:
- “Mechanical” (particles of clay, sand, organics, etc.);
- chemical;
- biological (bacteria, fungi).
Softeners stand out as a separate group. They are intended primarily to protect all kinds of household appliances and units from premature failure.
Types by the number of steps
By what other signs can a flow-through main water filter be selected? “Which is better to buy?”, The answer to this question depends, among other things, on what contaminants need to be removed. Separate filters can perform only one function - to clean it from dirt, salts or microbes. However, it often happens that the water in a well or well contains a large amount of various types of impurities. In this case, multi-stage devices are used. Their design includes several filter elements of different types.
In urban apartments, reverse osmosis systems usually perform the ideal water treatment . Water after such filters is obtained almost distilled. For all kinds of household needs, it fits perfectly. However, it cannot be used as drinking. To correct the situation, in addition to filters and membranes, special mineralizers are additionally included in such systems.
Large prefabricated systems are often installed in country houses, which may include rough and fine cleaning models, iron removers, ion exchange columns, ultraviolet disinfectants, etc.
Flowing water filter for main: which is better to choose
When buying a reverse osmosis system for an apartment, you should first pay attention to the volume of the storage tank and brand. These factors determine the service life and performance, and, consequently, the ease of use of the model.
Pipes in apartments are often mounted and electromagnetic water softening filters. When buying such equipment, it is worth paying attention primarily to its power. This parameter should be such that the device provides softening of all water used in the apartment. Such a flow-through water filter for cottages is also very suitable.
For a large residential country house, a water filter is usually selected based on laboratory tests. Without fail, only coarse cleaning devices are installed on the mains in this case. After all, impurities of sand and silt are present in water from almost all wells and wells. In this case, a flow-through main flushing water filter is usually purchased. In such models, the grid can be removed and cleaned or replaced with a new one.
As a softener for a large cottage, it is better to purchase an ion-exchange column. It is also worth putting an ultraviolet disinfectant in such a house.
Reviews about filters from different manufacturers
Equipment designed for water purification is produced by many companies today. Moreover, in most cases, only quite high-quality filters can be found on the market. Good consumer reviews have earned, for example, brand models:
- "Geyser". These devices are praised primarily for their high performance, sophisticated cleaning technology and ease of installation. If you wish, you can purchase a flow filter for water flowing main "Geyser" for some specific purpose or complex.
- Aqua Filter. Filters from this manufacturer received good reviews for the ability to process large quantities of water and not too high a cost.
- Atoll. The popularity of devices from this manufacturer is primarily due to its compactness, low price and excellent cleaning quality.
Of course, filters of other good brands are also being sold on the domestic market. For example, the Leroy Merlin mainstream water filter for water has earned good reviews, which is characterized by ease of use and a long service life. Also, AquaShield, Galaxy, and some others enjoy an excellent reputation among domestic property owners. All these devices have a rugged absolutely sealed enclosure (and therefore do not leak), process water efficiently and are quite productive.
