Self-washing water filters: principle of operation and subtleties of operation

Equipment that performs mechanical water purification and does not need to be replaced periodically is called a wash filter. Due to this feature, such a device is a more economical option, unlike models with replaceable cartridges. There are models of wash filters that perform washing themselves, that is, in automatic mode.

Such a system consists of some elements.

Namely such:

• it has a flask that is equipped with an inlet and outlet nozzle;
• The filter includes a mesh and a rotary valve, which is installed in the lower outlet of the flasks;
• pressure gauge, flush actuator and other automatic system, but not every model has components.

By the principle of cleaning such a system is quite easy. In this case, the mesh is installed in the lower and upper parts of the flask, water enters the flask through the inlet and flows through the cleaning cells, where dirt and harmful impurities remain, and then under pressure the water flows into the faucet.

In this system, there is another hole that is located at the bottom of the cleaning flask. This hole is closed when the filter is functioning.

After some time has passed, the cleaning cells may become dirty, and the purified water will flow under low pressure.

In this case, it is necessary to open the lower valve, and the water under its own force of gravity will begin to flow down. Thus the mesh is washed. After you have verified that clean water starts to go out of the hole, the valve must be returned to its original position.

But also the fact that such filters are designed for the purification of cold water, and they cannot cope with hot water, can also be attributed to the peculiarities.

But there are some models of filters that are universal. Such options can be installed for cold water, and for hot. The case of such filters is made of brass or bronze. The main disadvantage of such systems is their high cost. If we compare the cost of universal filters with the cost of filters for cold water, then plastic devices are much cheaper. In addition, if the plastic is transparent, then the owner will be able to determine the level of contamination of the cells.

Basically, self-cleaning water purification systems have nets. In such cases, the water is purified by passing through their cells. Meshes with small cells stop all contamination. Thus, dirt accumulates on them. This accumulated layer of dirt interferes with the normal passage of water, so the water pressure decreases.

The easiest option to remove the accumulated pollution from the grid - This is to get the net out of the flask and rinse it under running water, then install it on its seat. Such work is simple, but it takes some time.

But for this you need to open the bottom valve and wait for the result. After opening the faucet, the water under its weight begins to flow into the lower opening and thus washes and removes contamination from the grid. If you did not take care of the construction of a drain when installing the system, then during the cleaning period you will have to periodically change the tank into which the dirt will merge with the water.

Standard models of filters with a mesh are those in which you need to manually wash the contaminated mesh. But there are many such models. Some of them need to be disassembled to get and wash the mesh, and some can be washed without disassembling.

These filters are divided into two types.

• Filters with automatic washing mesh. For such systems, human intervention is not necessary, since the mechanism itself begins the cleaning process after a signal from the pollution sensor.Instead of a sensor, a timer and fill alarm can be set.

Models with semi-automatic flushing. In this case, the person acts as the start of the washing process. Cleaning in this case depends entirely on the constituent elements of the filter and on the design of the device itself.

These two types of systems can be used for systems with a heavy load. For example, with water supply complexes, for a service system for objects with a large amount of water consumption.

Still such filters divide into types on materials which were used for production of the case. The body can be made of polypropylene, plastic or metal. If the products are made of metal, then they use brass, bronze or steel for the manufacture.

As for the elements that carry out cleaning, they are of three types.

• The grid with small cells can be made of polypropylene or metal. Basically, these components are used for domestic use, but these nets are clogged much faster than other types of cleaners.
• Porous discs are made under the influence of the press, which is under high pressure.
• Filling cleaner that creates a porous structure after compaction.

These cleaning systems can be additionally equipped with pressure gauges, an element for pressure reduction and have a system of protection against water hammer.

The filter, which is self-cleaning, has a large number of advantages. With these advantages, you can save your time, since there is no need to regularly replace the filters, and the system itself has a long service life. That is, the owner saves not only his time, but also finances.

The main advantages of such systems:

• if flushing is performed, it is not necessary to shut off the water supply;
• this filter is able to perform its function without interruptions;
• the possibility of replacing elements of the system with newer ones, for example, you can install a mesh with smaller cells.

These are not all the advantages of a self-cleaning water purification system. If you take into account even the above advantages, it becomes clear that this principle of cleaning is convenient to use and very beneficial.

Each system has a passport in the package, which indicates the order of the installation process. Self-washing filter for water with a large flask is designed for water purification from the mud part.There is a self-cleaning filter with reverse and direct flushing with a counter. Thanks to this design, the user has the ability to control the waste of liquid.

The installation of such a device should be carried out in a room that is heated, since water can freeze in the system during cold weather. The installation itself is carried out with the cleaning flask down. At the same time the pipeline can be both vertical and horizontal.

When performing installation, an important task is not to confuse the direction of flow of water. The arrow that indicates the direction is located on the cap of the flask. If the cleaning system has an automatic flushing system, then in this case it must be connected to electricity.

In that case, if you purchase a filter for cleaning hot or cold water from the central highway, which may have the ability to coarse or fine cleaning,then for proper use the best option will be a system with backwash function. Such a system can be used for water purification at the dacha.

If we compare the filters for water purification with a mesh cleaner and with a disk cleaner, then in this case the disk cleaner is considered the best, since it has greater performance due to a larger filtration area.

Such a performance indicator often depends on the size of the filtering unit. But the disk filter is demanding on the pressure of water in the system, in contrast to the net, and the cost of such a filter is significantly higher.

Namely:

• will the installed filter be a separate system for one tap, or will it be installed in the system before the water supply system, which only enters the house;
• it is necessary to decide on the type of filter, whether it is compatible with the water supply system;
• choose a manufacturer of filters and its cost.

The most reliable systems are the filters of the Danish company Honeywell. Such filters are equipped with a backwash system and additional elements. Products of this company have high wear resistance and resistance to pressure drops in the water supply system. The main disadvantage of such systems is their high cost.

In order for the filtration system to optimally perform its function, you need to make sure that the water fully complies with the conditions of use of such a device.

Cleaning system is not desirable to install near heating systems. It is also necessary to monitor the pressure in the system: if there is high pressure in the system, the filter may fail and you will spend a lot of money on repairs.

With regular use of such a cleaning filter, it is necessary to wash the mesh. Flushing should be done about once every six months. If flushing is necessary before, it is easy to determine by water pressure, and if the flasks with cleaning elements are transparent, then you can see the degree of contamination.

In order to safely rinse, you must use the specified amount of water to flush the mesh. If the amount of water is increased, it is possible that some element of the system will fail.

There are many water purification systems for sale in our markets., but choosing the right option for you is difficult without a specialist. And also it is not necessary to install such systems yourself. It is better to use the services of specialized companies. Such companies will provide you with a large list of their services.
