The most affordable, and therefore the most popular way to purify water from suspended solids and impurities is to treat it with fine and coarse filters. After the water passes through the coarse filter of the inlets, it gets rid of mechanical impurities hazardous to health (sand, silt, rust, etc.), which can also ruin plumbing equipment. Then the water is sent to a fine filter. It, in turn, retains smaller particles that are not filtered at the initial stage: undissolved metal salts and some microorganisms, chemical and organic compounds.

Water purification is a must?
It is no secret that man needs water to survive. The human body is almost seventy percent water. Therefore, a lot of attention needs to be paid to the quality of the water consumed. As you know, tap water has a very low quality. It slowly destroys a person, increasing the load on his body.
Water is a good solvent for various chemicals, and therefore it is easily contaminated. Today, the use of clean water is one of the prerequisites for a healthy lifestyle. Therefore, many people who care about their health drink bottled water and use special treatment filters..
Unfortunately, municipal water supplies purify only the most dangerous types of pollution. For this, chlorine is mainly used, which is toxic and extremely harmful. In addition, utilities for the most part think only about what will be the quality of the water at the outlet of the treatment plant. But then water passes through pipes and can easily become contaminated again..
The water we use for cooking and drinks must be clean and of good quality.
In addition, increased water hardness is the cause of the deposition of salts in the human body. Negatively affects our skeletal system and high manganese content. Excessive amounts of iron in water cause liver disease, impair human reproductive function and increase the risk of heart attack.
It must be remembered that untreated water is not only harmful to the human body, but also spoils expensive imported plumbing. Limescale deposits clog small holes in the shower head and nozzle. Salts of magnesium and calcium under the influence of high temperatures form scale. And it, in turn, becomes the main reason for the failure of water heating equipment. Now there is even special plumbing designed only for purified water.
Water filter
A water filter is a device that purifies water from impurities, viruses, chlorine and its derivatives, bacteria, insoluble and mechanical particles, heavy metals, etc..
Household flow filters with a separate faucet combine cleaning efficiency and ease of use
For drinking water use household filters. They, in turn, are conditionally divided into 3 categories – the highest degree of purification, medium degree and protozoa. The simplest household filters include jugs and nozzles. The highest degree of purification is understood as cleaning with the most high-quality and advanced technology to date – reverse osmosis household filters.
Filter device classification
By scope of application:
- Household.
- Industrial.
- Aquarium.
- For a private home.
- Tourist – an alternative to boiling water. Small and designed to clean a small amount of water.
By cleaning method:
- Electric.
- Reverse osmosis.
- Ion exchange.
- Biological.
- Physicochemical.
- Mechanical.
Brass rough water filter
What is necessary for rough cleaning
This is the simplest filter element of the system with a minimum degree of purification, which is why it is called a coarse filter. All these filters are arranged in the same way and purify water only from large pollutants: rust, sand, etc. They are installed at the beginning of the wiring, that is, where water is distributed between the toilet, bathroom and kitchen. Inside the filter there is a special mesh, which is located along the water. Special retraction extends the life of the device. In case of blockage, you only need to shut off the water, unscrew the outlet and clean the sump. The same thing should be done every 3 months for preventive reasons..
The filter is delivered to consumers completely ready for use, and therefore additional adjustment is not required. Before installation, the pipeline must be cleaned of scale and rust. Systems of domestic hot and cold water supply, heat supply, heating, boiler-house pipelines after installation must be flushed with water until it comes out without mechanical suspensions.
The filter must not be subjected to stresses from the pipeline side (uneven fastening of fasteners, distortions, torsion, bending, vibration, compression, tension, etc.). If necessary, it is necessary to provide compensators or supports that will reduce the strain on the filter from the pipeline. The filter is installed with a “revision lid down”. If water is supplied from bottom to top, a horizontal section must be provided for filter installation. Special tools for installing the filter or removing it are not required. The filter on the pipeline must be fixed securely: water leakage on the threaded part is not allowed.
In large cities in many new apartments, such filters are installed by the developer. If not, then the filters can be easily purchased on their own. They are inexpensive and can be bought immediately with a crane. There are also special nozzles for the crane, which also represent a coarse filter. They are used when it is impossible to get to the pipes..
One-flask fine filter
Devices for fine water purification
It can be single-functional and multi-functional. Single-function designed for cleaning salts, heavy metals, rust and chlorine. Multifunctional simultaneously performs several functions and lasts longer – up to six months. All fine filters have inlet and outlet openings without a direct connection. Through the inlet, water is sent to a transparent container, where it, passing through the filter, is removed through the outlet.
The fine filter can be woven or mineral.
Woven Filter Cleaning
A woven filter is a cylinder with a special bundle or rope wound around it. This filter can purify water from some chemical additives, metal oxides, as well as insoluble salt crystals. It should be borne in mind that the most additives are found in hot water. This is done so that it stays hot for a long time. If the drum cloth has changed its color, this means that the filter needs to be replaced or cleaned. To clean such a filter, it is necessary to fill it with warm water and boil until it turns white.
Fine water filter extends the life of high-pressure apparatuses
Mineral filter – protection against chemistry
A mineral filter is a mesh cylinder filled with mineralized chips. It also protects against chemical additives and salts. The drum needs to be changed when plaque appears on the walls..
Deeper water treatment is provided by an adhesive filter. It reacts even with fractions dissolved in the liquid and thereby delays them. This changes the color of the drum. Care must be taken to monitor the replacement of the drum. Otherwise, a mistake can cause serious poisoning. In a block of flats, the fine filter drum needs to be changed once a quarter, even if hot water is turned off / on. Such a filter costs a little more. Moreover, expensive foreign filters are not always as reliable as they are usually thought of..
The biological protection filter appeared relatively recently. However, he has already managed to become popular all over the world. Such a filter almost completely disinfects water, protecting a person from various bacteria and viruses. It is put in addition to the main.
Water purification in a private house or in the country
All the filters described above are best suited for apartments. For water purification in a private house or in the country, it is worth using a filter system – a combination of several types of filters in one device. It works in automatic mode. Depending on the quality of the water, the filter system can not be changed up to a year. Some of these systems may self-clean. It is better to choose a system with a drive so that the water in this tank also settles.
