Coarse filters - application

Water, used for domestic 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 there are such problems. However, there is a way out of this situation. It consists in purchasing a filter for water purification and installing it in the water supply system. The coarse filters remove mechanical insoluble particles, which allows the water to be cleaned and enter the dwelling in a suitable 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 health and its environment. The filters for coarse water purification are selected based on the amount of impurities in the water and the productivity of the water supply system.

Kinds

Strainer

In this form, the filter element is a grid with small cells, the size of which is in the range of 20 to 500 μm. They can be self-cleaning, such as Honeywell water purification filters (their design allows to get rid of impurities accumulated inside, automatically). The second category is unpredictable, the device must be disassembled and cleaned manually to clean up their filter elements. The models intended for use in the cold water supply system have a transparent housing. The 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, which makes it possible to protect against shock and shock of a hydraulic nature.

Cartridge filter

The main filter element here is a replaceable type cartridge which is housed in a flask-housing made of steel or plastic. This kind reliably detains impurities. For the cold water supply system, the enclosure is transparent, for hot water systems - from opaque materials. As a rule, cartridge filters of rough cleaning are installed in systems having impurities of smaller size. Depending on the version of the cartridge, it can remove both mechanical impurities and chemical. For example, a cartridge made of felt impregnated with activated carbon can purify water from chlorine. The stocking type detains fibrous impurities, such as algae and mildew.

High-speed pressure filter

High-speed coarse filters consist of a column tank made of an anti-corrosion material and filled with a filtering composition. It is capable of retaining insoluble particles of 30 μm or more. The device has a control unit that is capable of automatically regulating the operation associated with the filtration of the flowing liquid and the regeneration of the filter element. This type of filter is used in cases where a significant amount of dissimilar impurities is present in water. On which option should I stop? The choice of the type of filter you need depends on the concentration of impurities in the fluid and their heterogeneity, the availability of free space in your home and your financial capabilities.
