Dalekane everyone knows that for his life a person drinks about seventy-five tons of water. At the same time with it, he "washed down", as Louis Pasternak believed, about eighty percent of his illnesses. According to doctors, along with water, a large number of microbes enter the body, accelerating the aging process.

Water purification

What is reverse osmosis? Reverse osmosis: a reliable filterReverse osmosis is one of the most famous ways of water filtration. It allows you to remove even the smallest particles that have the value of an ion. In addition, the "reverse osmosis" filter now helps to purify drinking water from salts and other inclusions. But that's not all: it improves the taste, color and even the properties of the liquid.

A process scientifically called "reverse osmosis" is hyperfiltration, during which water under high pressure flows through a special membrane that holds up impurities. Today, many companies - manufacturers of cleaning systems - produce filters that work precisely on this principle.

Technology

Not all of us imagine that the water that comes out of the tap in homes and apartments is, in effect, a solution. And in it in a certain amount contains numerous elements - metals, salts, inorganic and organic compounds and much more.

The reverse osmosis system as a method for purifying fluids has been known since the sixties of the last century. Originally it was used for desalination of saltwater on submarine submarines, today, on this principle in the world, many hundreds of thousands of cubic meters of drinking water are produced.

The improvement of technology made it possible to apply a reverse osmosis filter and at home. At the moment, almost all countries in the world have already installed such numerous systems in apartments and houses.

Filters working according to the reverse osmosis scheme solve not only the problem of water hardness, but also scale. No other cleaning technologies, including those that use ion exchange materials, are able to solve the mitigation task as effectively as the system data does. Therefore, if this problem is the priority, then the alternatives to these filters simply do not exist.

Final product

As evidenced by the testimonials, and this is confirmed scientifically, the filtered water thus has a unique degree of purification. As far as its properties are concerned, it is as close as possible to the melt, which is obtained from ancient glaciers. And this, as we know, is the most environmentally friendly and useful water for humans.

Principle of operation

The phenomenon of "reverse osmosis" is basic in the process of metabolism of any living organisms. Thanks to this principle, many nutrients enter the living cell and slags are also removed. It is possible to visualize what the reverse osmosis system is, by observing it with the example of two brine solutions having different concentrations and separated by a semipermeable membrane. The latter passes ions of a certain size, at the same time being a barrier to large molecules. As a result, water ions are able to penetrate through reverse osmosis, the membrane of which seems to be decanting, in turn, retaining the salts dissolved in them.

If solutions of different density are located on different sides of this semipermeable "partition", they will move from the weak to the more concentrated volume. In doing so, they will cause in the latter an increase in the level of the liquid.

Due to the reverse osmosis phenomenon, the process of molecular penetration through the membrane will occur even when both of these solutions are under exactly the same external pressure.

At the same time, the difference in level heights is proportional to the force under the influence of which water flows through the membrane and which is called "osmotic pressure".

Selection Criteria

In order to buy a reverse osmosis filter, you need to know the necessary parameters. Characteristics that distinguish this device determine the performance of the membrane and the volume of its accumulator tank. It is the filter's throughput that determines the amount of water that will be needed to meet the needs of a particular user.

As a rule, its production in these filters varies from one hundred eighty to three hundred and eighty liters per day. For industrial options, this indicator can be determined by a factor of a hundred times greater.

Proceeding from this, the choice is determined based on the individual needs of the buyer. For example, for a family of four, a tank with a capacity of twelve liters is sufficient.

Features

Those who are tired of the purchase of water in plastic bottles, causing sufficient damage to the family budget, it is best to think about water filters. After all, when buying reverse-osmosis cleaners, the user will get many benefits. First, at his house a harmless and very pleasant taste will flow from the tap, and secondly, the taste of tea, coffee and even soups will change. In addition, his kettle will no longer "suffer" from scale.

And all because the "reverse osmosis" system, on the basis of which these household filters work, purifies water using a thin-film special membrane. It functions according to the principle borrowed from Mother Nature. Water from the conduit passes through the semipermeable membrane tears away even tiny particles of the slurry - size about ten thousandth of a micron and transmissive only water molecules and oxygen removing dirty components in the drainage.

Varieties

According to the method of connection and type of functioning filters "reverse osmosis" is close to running varieties that are installed "under the sink". The installation of such a system is the connection to the water supply and sanitation. It can be quite easy to implement under the sink in the kitchen.

Plants have a “reverse osmosis”, in which after tanks and postfilters put the mineralizer, saturating the water with a complex of useful salts. When choosing you need to pay attention to the presence of the pump increases the inlet pressure. If the pressure in the water distribution system in terms less than three atmospheres, its existence on the device “reverse osmosis” actually.

In addition, because of the existence of a large number of manufacturers and models on the market, it is necessary to pay attention to the fixing methods, as well as to the filter elements, when buying. They need to be correlated with the possibilities of placement, for example, on or under the sink. The dimensions of this device also play an important role.

Another actual factor that should be chosen is the "reverse osmosis" filter model, the number of stages in front of the membrane, as well as their comparison with the composition of the fluid coming from the water supply system.
