The quality of the water coming from the water supply leaves much to be desired, so a variety of filters are used to clean it. Reverse osmosis equipment is one of the most demanded rightfully. It cleans the water passing through it as much as possible. Buyers are interested in installations, but they want to know for sure whether water after such purification is harmful to the body. Consider the pros and cons of reverse osmosis.
The method of water purification is extremely simple. Under sufficiently strong pressure, the liquid is literally forced through a special membrane. A porous material allows water molecules to pass through the holes, and with them elements of an equal or smaller diameter. This ensures the highest degree of purification at the molecular level. The water leaving the filter is very close to melted water or distillate in its properties.
The filter retains not only mineral or organic impurities, but also viruses, bacteria, hardness salts, various metals, etc. As a result of cleaning, 98% of impurities are removed, which no other equipment is capable of. At the same time, one must understand that among the harmful impurities present in water, there are many very dangerous for humans.
Wherever the water supplied to the house or apartment is collected, it is contaminated by both domestic and industrial effluents and waste. As a result, even in the most transparent and clean-looking liquid, microorganisms actively multiply, which can cause serious diseases: paratyphoid and typhoid fever, brucellosis, cholera, etc. In addition, helminth eggs, nitrates, toxic substances and much more may be present in the liquid.
Industrial enterprises throw the entire periodic table into the air. Sooner or later, these elements end up in the water. Phenol, heavy metals, organic solvents provoke oncological diseases and serious mutations at the genetic level, have a teratogenic effect on the developing fetus. Zinc, cobalt and lead affect the liver, kidneys and cardiovascular system. This list can be continued for a very long time.
Reverse osmosis filters purify water from all these contaminants. However, it would be premature to think that the water that has passed through the filters is useful. Many experts believe that reverse osmosis is the personification of the well-known saying that the best is the worst enemy of the good. First of all, this refers to the benefits that water purified in this way brings.
It is practically a distillate. Doctors tirelessly argue about the dangers and benefits of this liquid. It has been proven that not only harmful, but also vital substances are dissolved in ordinary water. First of all, these are natural mineral elements that are used for normal life. In the process of purification, water loses not only dangerous, but also useful impurities.
Thus, it is impossible to talk about the benefits of using distillate as drinking water. It is reliably known that short-term use of completely purified water can be considered conditionally safe for the human body. With prolonged use, the salt balance, which is considered one of the most important metabolic processes, suffers. It regulates the combination of quality and quantity of different salts present in living organisms.
Violations of this balance always has consequences for the body. With its decrease, the bone tissue becomes thinner and becomes very fragile. Similar processes take place in cartilage tissue. It loses elasticity, which leads to the appearance of painful manifestations during physical activity, especially when walking, the development of arthrosis. When the salt balance deviates towards an increase in the body, an uncontrolled deposition of salts begins.
The reverse osmosis membrane also retains the so-called nutrients needed by the body. The absence or too small amount of mineral elements in water adversely affects health. Magnesium deficiency, for example, leads to the development of periodontal disease, muscle cramps, dangerous arrhythmia and arterial hypertension. Scientists say that long-term use of “ultra-purified” water is dangerous to health.
For this reason, reverse osmosis filters are equipped with a post-treatment unit. It includes ionizers and special mineralizers for water. The ionizer is a device that gives structured water with a predetermined pH level. In other words, the device produces the so-called alkaline or acidic water. Both types of liquid find their application.
It is believed that alkaline water has a pronounced antioxidant effect on the body, while acidic water has a disinfectant effect. Mineralizers saturate the water with minerals that are lacking in the purified liquid. These can be different substances, the composition of additives depends on the type of removable mineralizer cartridge. If you wish, you can choose the best option based on your own needs.
A water silvering agent may also be present in the post-cleaning unit. This is the name of a device that saturates drinking water with silver ions. It is believed that it is very beneficial for the body. However, doctors warn that water with additives does not bring such benefits as natural water.
Summing up, it should be emphasized that neither the harm nor the benefits of using drinking water purified by reverse osmosis has been proven. Is it worth drinking, everyone decides for himself
