Recommendations for choosing a reverse osmosis system

When choosing a filter, it is important to focus on 3 main indicators: the initial water quality, the availability of space under the sink for installation and the pressure in the water supply. The dirtier the water, the more purification steps should be in the system you choose. If you plan to install a filter in an apartment, then the best option would be an installation with 3-5 steps. For a private house, it is better to purchase six-stage models or additionally install a pre-filter that will trap large fractions of rust, sand, and metal.

Most reverse osmosis systems are installed under the sink. Don’t have much space under your sink? Then take a closer look at compact direct-flow filters without storage. They occupy a minimum of space, while they have good performance.

Reverse osmosis filter: reviews of owners, scientists and doctors

Humanity has been thinking about the need for water purification for a long time. As soon as people did not try to filter water, they used a variety of devices for this, but still it was not possible to achieve the desired result. A fundamentally new approach to this issue was obtained only in the 20th century.

Reverse osmosis water treatment — how did it all begin?

history reverse osmosis filters started over a hundred years ago. Officially, reverse osmosis began its countdown as a filtering installation in the seventies of the twentieth century. The number of industries where this technology is used cannot be counted:

· The medicine;

· Food industry;

· Domestic use.

The reverse osmosis filter helps to get not just soft water, it will easily give out distillate. And now many areas require water of this quality! In everyday life, it is advised to use this cleaning device, because. it softens water very effectively and not only. The entire load in the filter is carried out by a semi-permeable membrane. This is the most vulnerable part of the device. It is very easy to damage! Therefore, only prepared water is used for cleaning in this filter.

The membrane helps to eliminate harmful impurities, some types of bacteria. Anything that is dissolved in water is best eliminated by such a semi-permeable membrane barrier. The advantages of this filter include the fact that the water is not heated to obtain softness.

Over time, the membrane becomes unusable and it is extremely important not to miss the moment of replacement. Check the condition of its clogging with TDS meter

. Cleaning is carried out in automatic (without human intervention) or semi-automatic mode.

The filtration process itself lies in the fact that there is a certain barrier that filters out unnecessary impurities, and only pure water passes through. In a reverse osmosis system, cleaning is a little different. Pressure drops help to squeeze good water through a poorly permeable membrane. As a result, it is possible to filter out even what other devices are not subject to.

Reverse osmosis filters are able to retain any impurities larger than 0.3 nanometers. It turns out that the filter removes such components as:

No wonder the reverse osmosis filter gets the appropriate reviews. Although this is a fine purification plant, it works to some extent like a small water treatment system. Such a system is able to keep two extremely harmful viruses for humans — hepatitis and, in addition, cholera. This already gives him a very large edge.

Reverse osmosis water purification has its rather impressive disadvantages. Although they have been arguing about them for a long time and they will not come to any kind of consensus, they will not agree. Osmosis removes minerals from water. Moreover, both useful and harmful. The total mineralization of water after treatment with an osmosis membrane is no more than 100 milligrams per liter. Sometimes it can drop to three milligrams per liter.

Benefit or harm? Reviews of scientists and doctors

According to the recommendations of scientists and doctors, good drinking water should have a mineralization of 1000 mg / liter. The distillate should show no more than ten. It turns out that the water treated by osmosis becomes extremely acidic. And her level of acid-base balance drops dramatically. This is no longer natural water, which means that there is less and less benefit in it.

There is a very big debate about the benefits of osmosis. Two facts contradict all reviews. The mineralization of water purified in this way is much less than 100 mg/liter. But at the same time, the same US naval forces use water purified in this way on an ongoing basis, and there they do not complain about non-desalinated water. Although you can restore the balance of minerals with the help of products.

Many doctors blame membrane cleaning — it removes beneficial minerals from the water. But for some reason, no one focuses, does not focus on the fact that minerals of inorganic origin and harmful effects are eliminated from the water.

Softened water cannot have a special effect on the human condition. As well as plumbing. Unless you’re severely allergic to chlorine. Man himself is a storehouse of salt water. At the same time, the salinity of the water contained in the human body is almost 3000 mg / liter. It’s like sea water in terms of salinity. And if we compare it with water after osmosis, then the water after membrane purification is one hundred and fifty times more desalinated. Therefore, there is no difference whether to take osmatic water or tap water.

To replenish the minerals lost during purification, it is not necessary to mix purified water with hard water. You can always replenish the missing minerals by eating certain foods. It will be enough to add to the diet: dairy products, fish, vegetables and fruits. It is not necessary to drink liters of water, it is easier to eat 200 gr. cottage cheese and get the required amount of calcium per day.

Moreover, despite the fact that there is a massive promotion of a healthy lifestyle. Scientists and doctors recommend drinking up to 2 liters of water per day, but people still drink little water directly. That is, they consume coffee, tea, eat soups and borscht, but water is still out of work. Thus, it is still not worth talking about the dangers or benefits of osmatic water — a person still does not consume as much water per day as necessary. And by doing so, he cannot harm himself.

Another disadvantage of a reverse osmosis water filter is its price. Depending on the manufacturer (Russia, Germany or the USA), the price of a filter can reach 17,000 rubles. for 1 set.

Water after a reverse osmosis filter — what is its usefulness?

Water after treatment with such a fine purification device becomes practically sterilized. And this is often the reason for the disadvantages of reverse osmosis installations. But you should not use hard low-quality water, when you can get all the necessary minerals from food. So, the question of the harmfulness of osmatic water is quite controversial. Reverse osmosis filter reviews of the owners about it say that it is possible to clean the water with the highest quality only with the help of this purification device.

The human body is able to obtain all the main useful substances and minerals from cereals, vegetables, fruits, as well as meat and fish. It is always more beneficial to eat a glass of wholesome homemade milk than to experiment with lime water.

In addition, modern society drinks very little direct ordinary water. Coffee, tea, juices are used. And very little when ordinary water, albeit specially purified and saturated with natural minerals.

The essence of reverse osmosis cleaning is reduced to working with water of three stages of purification. Although the system is almost perfect, it also failed to avoid shortcomings. There are three more filters inside the housing of such a filter. Or these filters are connected in series and gradually remove impurities from the water.

The first stage is the elimination of any solid impurities, albeit very small ones. Here is the usual carbon adsorbent. This is followed by mechanical cleaning, elimination of organoleptic impurities. And only the final stage will be reverse osmosis fine cleaning. As a result, water is freed from any kind of impurities, with the size of harmful molecules larger than the size of a water molecule. Mineral impurities, including lime salts, viruses and microorganisms, nitrates and sulfates, fall under this category. Only this type of water purification can insure a person from infection with cholera bacillus or hepatitis C. In general, this includes a lot of diseases caused by bacterial spores in water.

Well-known and best manufacturers of filters for washing with reverse osmosis (with a mineralizer):

1. Aquaphor
2. Geyser Prestige
3. Atoll
4. new water
5. Barrier

Scientists often believe that reverse osmosis water becomes too acidic and unhealthy. But the defenders of osmosis are on a different version of the development of events. The first argument they give is a drastic reduction in the list of diseases that can develop due to the presence in the water of certain bacteria that are eliminated by osmosis. The same hepatitis and cholera, after treatment with membranes, are not terrible for a person. Of course, not all viruses are eliminated, but quite a sufficient number of them.

The thin osmotic membrane removes most of the salts from the water. What is the reverse osmosis filter reviews of owners and buyers about it and testify. After cleaning, the water becomes soft. Let not the same as after ion-exchange treatment. But this degree of cleansing helps to get both soft leather and undamaged laundry after washing. This water is definitely better. Today it is impossible to build a healthy lifestyle without such water.

Using a reverse osmosis system allows you to keep the slag contained in the water. In turn, their elimination is a guarantee of the normal functioning of the gastrointestinal tract. That is, water purification, thus, promises a lot of good. Where is the negative? Is the elimination of natural minerals so important? But the disadvantages of reverse osmosis are not limited to this. One of the first features of water treatment is that too much water is involved in the purification process and too much of it goes to the utilizer. The purification process itself takes much longer than other methods. You can also add here the high cost of both the device and replaceable membranes.

The first drawback mentioned by everyone is the poverty of water for minerals. But they can be obtained naturally from food, without even thinking too much. Then, for all its high degree of filtration, the membrane is not able to remove chlorine from the water. This means either drinking soft chlorinated water, or additionally cleaning it, which already adds costs to an expensive reverse osmosis water filter. And the accumulation of chlorine in the body is also far from useful.

The membrane passes well divalent metals, which often turn out to be toxic, poisonous. With individual intolerance, such water can be poisoned. However, there has been no official confirmation of such poisonings yet. Therefore, this information can still be called a fiction or a version. Therefore, the benefits of buying an Aquaphor or Geyser reverse osmosis filter are much greater. Especially for industries with specific needs. And for home use, you can always either put on air conditioning or eat a good portion of cottage cheese to achieve balance.
