Children have not yet
formed immunity, so they are especially prone to the dangers of poor quality
water. Parents are all well aware of this, therefore, as a rule, they try not
to use tap water, but often prefer children's bottled water. However, not
always this water is suitable for children, since it is intended for long-term
storage, which means that in the course of time, pathogenic microbes may appear
purification of water is performed in multi-stage filtration systems. They
allow to purify water from virtually all pollutants: mechanical (silt, sand, rust),
chemical (chlorine and chlorine compounds, heavy metals, colloidal compounds,
nitrates, herbicides, oil products, hardness salts, etc.) and biological
(viruses, bacteria, and fungi).

The results of a comprehensive assessment of water quality from the trade network in Kiev are presented using analytical chemistry, biotesting using a set of animals and plant test organisms, and microbiological analysis. The criterion for assessing water quality was the integral indicator in conventional units, which allowed to classify the studied waters in one of four categories: "not dangerous", "conditionally dangerous", "dangerous" and "very dangerous".
main difference between the two filtration systems lies in the specific
features of the purification technology, which in turn affects the chemical
composition and physical properties of the produced water. And, depending on
the characteristics that the source water has, the spheres of its application
are also different.
Thus, in the process of filtration using standard reverse osmosis, only molecules of oxygen, water, and proportional elements are passed through it. Therefore, as a result, the initial water is practically sterile with an acidic pH.

DESALINIZED WATER & LIFE ACTIVITY OF MICROORGANISMS
Regarding the impact of demineralized water per person are different opinions. Some scientists believe it useful to health, others point out that this water (or purified from salts and trace elements) - is harmful, causing imbalance of the body, lowers its resistance leads to various diseases. Who is right? The authors based their literary and experimental data, trying to find a reasonable answer to this question.
are used in multi-stage water treatment systems for additional processing. In
our devices, we use two types of auxiliary cartridges - "VITAL MIX"
and "VITAL BLOCK".
The post-filter "VITAL MIX" uses a
unique patented filter mixture, which includes only natural materials. Its
advantage is that by using such cartridge the water is further purified from
free chlorine and its compounds, dissolved iron, manganese, ammonium,
oxidability, and nitrates.
Areas of application for Vital Mix Optima, Vital Mix Nano, and Vital Mix Medical pressure cartridges
time of continuous social, economic and environmental shaking, water from
almost every source before consumption must undergo special training, part of
which is its purification. After all, even clean, at first glance, well water
can contain nitrates, and in artesian due to equipment malfunction may appear
and multiply various microorganisms. And is it worth remembering again the
quality of tap water ...
- You, surely, would
not mind to indulge yourself with a small cup coffee or tea in the morning. But
you certainly have no wish to cook these drinks with water from under the faucet
(bottle). And even if boiling saves water from some harmful components,
something will survive even at 100 degrees all the same.
Moreover, water from underneath the faucet gives a strange smack to the drink which will discourage you to drink it. In order to disclose the true taste of tea or coffee fully, one should prepare water by their own hands for this purpose.
