Water used for household needs of a country house or cottage may contain impurities of a mechanical nature. The fact is that the state of some communications leaves much to be desired, so such problems arise. However, there is a way out of this situation. It consists in purchasing a water filter and installing it in the water supply system. Coarse filters trap mechanical insoluble particles, which allows water to be purified and enter the dwelling in a usable form. The principle of their action is to filter insoluble particles, they do not contain any chemical reagents, and therefore are absolutely harmless to human he alth and the environment. Coarse water filters are selected based on the amount of impurities in the water and the performance of the water supply system.
In this form, the filter element is a mesh with small cells, the size of which is in the range from 20 to 500 microns. They can beself-cleaning, such as Honeywell water filters (their design allows you to get rid of impurities accumulated inside automatically). The second category is non-flushing, to clean their filter elements, the device must be disassembled and cleaned manually.
Models designed for use in the cold water supply system have a transparent body. Coarse filters used in hot water systems are made of metal. In addition to performing their basic functions, they can be equipped with a pressure control valve, this allows you to protect against surges and shocks of a hydraulic nature.
The main filter element here is a replaceable type cartridge, which is located in a flask-case made of steel or plastic. This type reliably retains impurities. For a cold water supply system, the case is made of transparent, for hot water supply systems - from opaque materials. As a rule, coarse cartridge filters are installed in systems with smaller impurities.
Depending on the performance of the cartridge, it can remove both mechanical and chemical impurities. For example, a cartridge made of felt impregnated with activated carbon can purify water from chlorine. Stocking type traps fibrous impurities such as algae and mud.
High-speed pressure filter
High speed coarse filtersconsist of a container-column made of anti-corrosion material and filled with a filter composition. It is capable of retaining insoluble particles with a size of 30 microns or more. The device has a control unit that is able to automatically regulate the work associated with the filtration of the flowing liquid and the regeneration of the filter element. This type of filter is used in cases where the water contains a significant amount of heterogeneous impurities.
Which option should I choose? The choice of the type of filter you need depends on the concentration of impurities in the liquid and their heterogeneity, the availability of free space in the home and your financial capabilities.

Bedding for centuries and even millennia was an attribute of luxury, and they were used only by representatives of the upper strata of society. And this is not surprising, since before the invention of the semi-mechanical loom in the first half of the 18th century, the production of fabrics, especially with a wide canvas, required enormous physical costs and time
