Self-washing filter for water: washing filter for mechanical water treatment

Cleaning the water entering the apartment from various mechanical impurities is very important. Not only the final quality of the liquid used in drinking depends on it, but also the service life of all kinds of household appliances. Ordinary filters for wateras a rule, they require periodic replacement of cartridges after the filter element has reached its end of life. The washing filter for mechanical water treatment is much more convenient, since it allows you to restore, at least partially, the characteristics of the cleaning element in a short time. In some cases, it does not even need to be removed.

Principle of operation

In ordinary mechanical filters nets or replaceable cartridges are located. At some point, they become clogged, and are no longer able to properly filter the water. Then you have to shut off the water supply and unscrew the filter element to replace it or clean it with improvised means. This is not always convenient, since very often these devices are located in hard-to-reach places.

Self-washing water filters do not have this drawback. They have a special crane. When the washing mode is activated, dirt washed off from the filter element is removed through this washing valve. The method may differ: a special turbine, water supply in the opposite direction. Naturally, before washing the filter, it is necessary to place a basin under the tap, and it is better to connect it to the sewage system.

Benefits

The advantages of water filters without replaceable cartridges are obvious:

• Significant monetary savings, since there is no need to purchase replacement parts having a limited service life.
• Maintenance of such units is much more convenient and should be carried out after a longer period of time.
• The cleaning process does not require a cessation of water supply in the apartment.

The disadvantages of self-washing devices include a rather high cost and exactingness to the parameters of water supply to the room.

Kinds

The size of the captured impurities emit:

• A fine filter capable of picking up pieces of rust and sand with a size of 20-50 microns.
• Coarse cleaning devices that allow filtering of elements with a size of 100-500 microns.

Depending on the temperature of the liquid, there are coarse and fine filters:

• For cold water.

Devices for cold water often have a transparent case, which is very convenient: you can "by eye" determine how dirty the filter element is.

• Hot water filter. It has a more robust design that can easily withstand significant temperatures. His "cold" brother in such conditions will be deformed, so you should not confuse them in places.

By the nature of the cleaning element, the following filters can be distinguished:

• Mesh. The most common and least "moody" design. In such devices there is a special turbine that accelerates water, which cleans the grid. System shutdown is not required.
• Disk. More expensive and demanding. Often you can find such filters for water with backwashing, which is not always available in mesh. They have more performance.

According to the method of cleaning, self-washing filters are:

• Washed by hand. This does not mean that you have to remove the filter element from the system. The procedure can be carried out even without stopping the water supply. But manufacturers still recommend removing and washing the mesh separately. Although this is not a very convenient procedure, it will have to be performed much less frequently than replacing replaceable cartridges. In addition, it does not require any financial costs.
• Semi-automatic. For such models, manually only have to give a command to clean, the system will do all the work itself. In different models of different manufacturers, self-cleaning filters are cleaned differently, a lot depends on the type of cleaning element and the design of the unit.
• Automatic. The process starts due to the readings of various sensors. Another option - cleaning is performed according to a pre-set timer.

The last two species are rarely seen in a separate apartment. Such self-washing units are more often used on high-pressure main pipelines, which serve to supply water to pools or entire houses.

Self-washing filters can be equipped with various add-ons:

• Pressure gauge. It is especially convenient if these devices are located before and after the filter system. Then, by the pressure difference on the manometers, one can judge the degree of contamination of the device and clean it in a timely manner.
• Pressure reducer. Protects the entire system, including the filter, from water hammer during sudden changes in pressure in the water supply.

How to choose a self-cleaning filter

Selection tips will be as follows:

• First of all, you need to decide on all the parameters of the system in which the unit will be installed. These include pressure and water temperature.
• Make sure that the diameters of the pipes and filter connections are the same. Or consider options for their fit.

It is better to purchase self-washing filters of well-known manufacturers. You can focus on the reviews of friends and acquaintances. This will save you from unnecessary surprises, save money and time.

Leading manufacturers

The undisputed market leader in these products is the Danish company Honeywell. Its products are distinguished by the highest reliability. The excellent quality of the components ensures a long service life and the replacement of individual parts of the unit if necessary. Honeywell water filters are complemented by pressure gauges and pressure reducers. The only thing that limits the demand for the products of this company is its high price.

Various modifications of self-washing filters of Italian TIEMME, German SYR, as well as Valtec and Itap companies gained great popularity on the market. In the wide range of their products you can easily find the required filter option depending on your capabilities.

Of the Russian manufacturers, the Geyser company should be noted. Its filters successfully compete with European manufacturers not only in our country, but also in the global market. Geyser prefers more specialized models, releasing as filters for individual use in the apartment, as well as entire complexes for water treatment for country houses and even enterprises. With high quality treatment plants, a more reasonable price often speaks in favor of the Russian manufacturer.
