Filters for coarse cleaning
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 the purchase of a filter for water purification and its installation in the water supply system. Coarse filters retard the mechanical insoluble particles, which allows the water to be purified and in a suitable form to enter the home. The principle of their action is to filter insoluble particles, they do not contain any chemical reagents, and therefore 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.
In this form, the filter element is a grid with small cells, the size of which is in the range from 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 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 allows to protect against shock and shock of a hydraulic nature.
The main filter element here is a replaceable type cartridge that 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 retains 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 in size. 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 contained 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.
