Filters coarse and fine purification of water: designation, classification

The most accessible and therefore most soughtprocess water treatment from suspended solids and impurities is its treatment of filters and fine strainer. After the water passes through the coarse filter inputs it gets rid of hazardous solids (sand, silt, rust and other.), Which, moreover, can spoil and sanitary equipment. The water is then sent to the fine filter. It, in turn, delays the smaller, not filtered out at the initial stage particle, insoluble metal salts and some microorganisms and chemical and organic compounds.

Clean water - a necessity?

It is no secret that water is needed for human survival. The human body is nearly seventy percent water. Therefore, much attention should be paid to the quality of water consumed. As is well known in the tap water is very low quality. It slowly destroys a person by increasing the load on his body.

Water is a good solvent differentchemicals, so it is fairly easily contaminated. To date, the use of clean water - this is one of the prerequisites for a healthy lifestyle. Therefore, many people who care about their health, drink bottled water and use a special water treatment filters.

Unfortunately, water municipal water supplyclean only from the most dangerous types of pollution. For this chlorine is mainly used, which are extremely toxic and harmful. In addition, utilities at most only think about what will be the quality of water leaving the treatment plant. But then the water passes through pipes and can easily become contaminated again.

Pure water - your health

The water that we use for food and beverage, must be clean and high-quality

Moreover, increased hardness of the water iscause salt deposits in humans. Negatively affect our skeletal system and the high content of manganese. Excessive amounts of iron in water causes liver disease, violates the human reproductive function and increase the risk of heart attack.

It should be remembered also that the raw water is notonly harmful to the human body, but also spoil the expensive imported sanitary ware. Lime deposits clog the small holes in the shower nozzle and nozzle. magnesium and calcium salts at high temperatures form a scum. And she, in turn, becomes the main reason for failure of the heating equipment. Now there is even a special plumbing calculated only purified water.

Water filter

Water filter - a device that cleans the impurities from the water, viruses, chlorine and its derivatives, bacteria, and mechanical insoluble particles, heavy metals and so forth..

Flow built-in filters

Household flow filters with separate faucet combines the cleaning performance and ease of use

For drinking water, domestic usefilters. They, in turn, conventionally divided into 3 categories - extremely clean, moderate and simple. For simple household filters include pitchers and tip. Under the highest purity understand cleaning best quality and advanced technology to date - household reverse osmosis filters.

Classification for filtering devices

By application:

  • Household.
  • Industrial.
  • Aquarium.
  • For private homes.
  • Travel - an alternative to boiling water. Are compact and designed to clean a small amount of water.

By the method of purification:

  • Electric.
  • Reverse osmosis.
  • Ion exchange.
  • Biological.
  • Physico-chemical.
  • Mechanical.

What is needed for the coarse

This is a simple filter system elementthe minimum degree of purity, and therefore is called the pre-filter. These filters have the same structure and purified water only from major contaminants: rust, sand, etc. They are placed at the beginning of the wiring, ie. E., Where the water is distributed between the toilet, bathroom and kitchen. Inside there is a special mesh filter, which is located along the water. Special outlet prolongs life. When blockages need only cut off the water, unscrew the tap and clean the sump. The same should be done every 3 months from preventive reasons.

The filter is delivered to consumers fullyready to work, and therefore do not require further adjustment. Before installation, the pipeline should be cleaned from scale and rust. Systems of internal hot and cold water supply, heat supply, heating, boiler pipes after installation should be rinsed with water to release it without mechanical suspensions.

The filter must not be subjected to stress fromside pipe (uneven tightening of fasteners, distortions, torsion, bending, vibration, compression, tension, etc.). If necessary, compensators must be provided, or support, which will reduce the load on the filter from the pipeline. Filter set "cap revision downwards." If water is pumped from the bottom up to the filter mount must be provided to the horizontal section. No special tools to install the filter or disassembly is required. Filter the pipeline must be secured reliably: water leakage along the thread portion is not allowed.

In large cities, many new homes arefilters are installed by the developer. If they do not, the filters can be easily purchased on their own. They are reasonably priced and can be purchased directly from the tap. There is also a special attachment to the crane, which also represent the coarse filter. They are used when it is impossible to get to the pipes.

Devices for fine purification of water

Maybe monofunctional andmultifunctional. Singlefunction for cleaning from salts of heavy metals, chlorine and rust. Multifunctional simultaneously performs several functions and lasts longer - up to six months. All Hepa filters has input and output holes without a direct connection. Through the inlet water is sent into a transparent container, where it passes through the filter is removed via the outlet.

The fine filter may be woven or mineral.

Cleaning the filter cloth

Woven filter is a cylinderwound on his special harness or rope. Thus the filter can be cleaned with water from some chemical additives, metal oxides and undissolved salt crystals. Keep in mind that most of additives contained in the hot water. This is done in order to keep it hot for a long time. If the drum cloth changed its color, it means that the filter should be replaced or cleaned. To clean this filter, you must fill it with warm water and boil until it becomes white.

Fine filter water treatment

Filter fine water prolongs the life of the high-pressure devices

Mineral Filter - protection from chemicals

Mineral filter - a mesh cylinder filling saline crumbs. It also protects against chemical additives and salts. Drum should be changed, with the appearance of plaque on the walls.

Deeper water purification providedadhesive filter. It reacts with dissolved even in the liquid fractions, thereby delaying them. This changes the color drum. It is necessary to carefully monitor the replacement of the drum. Otherwise, the mistake can cause severe poisoning. The apartment building fine filter drum needs to be changed once a quarter in the case of disable / enable hot water. It is worth a little more expensive filter. Moreover, expensive foreign filters are not always as reliable as they might think.

biological protection filter appeared relativelyrecently. However, it has already become popular around the world. Such a filter is almost 100% disinfects water, protecting the person from various bacteria and viruses. His addition to the basic pose.

Water treatment in a private home or at the cottage

All the filters described above are best suitedfor apartments. To clean the water in a private home or cottage, you should use the filter system - a combination of several types of filters in a single device. It works in an automatic mode. Depending on the quality of water filter system can not change to a year. Some of these systems are self-cleaning. It is best to choose a system with the store, so that the water in the tank is also advocated.
