Water is an invaluable substance on the planet, on which the existence of all living organisms depends. Even a person is 60-65% liquid and to keep the body in good shape, you need to drink at least 1.5-2 liters of pure water every day. But how to do this if the tap liquid often contains harmful organic and inorganic impurities that can be harmful to health? To obtain high-quality drinking water, special filtering installations are used — reverse osmosis systems.

Choice Recommendations

Reverse osmosis systems provide a high degree of water purification, the efficiency of which reaches 99%. But since there are different types of such equipment on the market, people often have difficulty choosing the right option. According to the principle of operation, such installations are almost identical, and the differences affect only the appearance, equipment and equipment.

Cleaning levels

When choosing a reverse osmosis system, special attention is paid to the stages of purification. Usually 5-7 steps are used. In most cases, reverse osmosis stations have 5-level purification:

  1. At the first stage, the elimination of rust and suspended impurities is carried out.
  2. The second level involves the dissolution of chlorine using a charcoal filter with a granular structure.
  3. At the third stage, organic impurities and heavy metal inclusions are removed using a block cartridge.
  4. The fourth stage of purification is performed at the molecular level by means of a reverse osmosis membrane. Only water and dissolved oxygen molecules pass through its pores. Part of the water flow is discharged into the sewer, and the other part ends up in a reservoir called permeate.
  5. The last level is to correct the smell and taste of drinking liquids using a carbon post-filter. This element is made of activated carbon and coconut shell with the addition of silver ions.

Such systems allow you to prepare completely clean water for culinary and other tasks. Additional stages are necessary to saturate the liquid with minerals or structurization.

Type of mineralizer

After passing through a 5-stage purification, the water becomes ready for drinking and cooking. However, drinking it raw is not recommended due to low mineralization. To get rid of such shortcomings, manufacturers use additional processing with a mineralizer.

Such a component is made from natural calcite and is used to saturate water with useful substances.

Bioceramics or structurizer

Separate reverse osmosis systems are equipped with an additional level of water treatment — a bioceramic tourmaline cartridge or a structurizer. This component is responsible for generating infrared radiation and an electromagnetic field to separate molecules into particles. After such treatment, the structure of the molecules acquires the correct crystallization, as in melt water. Such a liquid is better absorbed by the body and has a positive effect on the vital activity of cells, accelerating metabolic processes and strengthening the immune system.

7-stage filters are considered the most efficient, as they provide a full range of water enrichment. However, their cost is quite high, so you can get by with a 5-stage analogue.

Types of reverse osmosis systems

In the traditional version, the water treatment plant is equipped with a 9 or 12 liter tank, which is located under the sink. The tank accumulates liquid and stores it under pressure, solving the problem of insufficient performance of the reverse osmosis membrane in household equipment (5-8 l / h). In addition, such a container provides an additional supply of drinking water in case of problems with water supply.

Such installations are considered the most affordable and easy to install. If there are no problems with free space in the house, then such a system will become indispensable.

In other cases, the following types of reverse osmosis stations can be selected:

  1. Devices of the Comfort series with bayonet cartridges. They are also equipped with purified water storage tanks, but are more compact and easier to maintain. Replacement of cartridges is made by one click. However, due to the use of flask-shaped bayonet cartridges, such systems are more expensive than classic ones.
  2. Compact stations that are produced in a single housing with a tank. They are characterized by compact dimensions, attractive design and the possibility of installation both under the sink and outside. Often equipped with a display that displays important data about the operation and current status of the cartridges.
  3. High-performance plants without a tank. Able to process up to 1500 liters of water per day and do not require the placement of a storage tank.

In addition, on sale you can find computer-controlled units that are equipped with a digital display that shows the current status of work and the state of the elements. The electronic filling constantly evaluates the quality of water and the degree of wear of the cartridges, and also indicates the need to replace them. In addition, the device has an automatic flushing of the membrane to increase the service life.

General selection criteria

When choosing a reverse osmosis system, you should be guided by the following criteria:

  1. Number of cleaning steps.
  2. Compliance with the dimensions of the equipment allocated for installation site.
  3. Performance parameters and operating life of the membrane.
  4. The presence of a pump.
  5. The volume of the storage tank and the material of its manufacture.
  6. manufacturer’s reputation.
  7. Additional functions and features.
  8. Crane execution.
  9. Flask type.
  10. Availability of a guarantee.
