Most people don't drink raw tap water. We prefer bottled, boiled or filtered mineral. The operation of osmotic water filters is based on one of the processes that occur in nature - osmosis. It was used to build a filter, and the water obtained in this way was almost 100% free of impurities.
What is the process of osmosis and reverse osmosis?
Osmosis is a process that occurs in all living organisms. It consists in passing through a semipermeable membrane of water molecules from a solution with a lower concentration to a solution with a higher concentration of molecules. The reverse osmosis process used in water filters is precisely the reverse of the process, i.e. filtering. Under the pressure of the water network, only water molecules are squeezed through the semi-permeable membrane. There is a flow from a more concentrated solution (dirty water) to a less concentrated solution (clean water).
Operation of the osmotic filter
The reverse osmosis filter is usually installed in a cabinet under the kitchen sink. Its heart is a semi-permeable osmotic membrane, which - to put it simply - works on the principle of an extremely precise sieve, using the natural process of reverse osmosis, i.e. the penetration of solutions with a higher concentration (one side of the membrane) to places where there is a lower concentration (the other side of the membrane) .
Filtered water must be mineralized
Water purified in an osmotic filter must be additionally mineralized. The crystal clear water obtained in the filtration process will certainly not harm our body. However, in order to treat it as the main source of thirst quenching, it is good to subject the water to the mineralization process. The reverse osmosis process effectively filters all impurities, but removes calcium and magnesium compounds from the water, which are responsible for maintaining the minimum water hardness. Thus, drinking it, we do not provide the body with these important minerals. This problem does not exist in the case of filters equipped with mineralizers, which supplement the water composition with valuable elements.
Advantages of filtered water
How accurate is the reverse osmosis filter?
Thanks to filteringthe water is free of rust, sand, mechanical impurities, heavy metal compounds, as well as bacteria and viruses. The reverse osmosis filter retains about 96% of all substances in the water, including even the tiniest ones.
Water with too low or too high temperature will not be filtered thoroughly
The temperature of the filtered water should not exceed 30 degrees C, because too warm water may disturb the filtration process or damage the osmotic membrane. Too cool water (below 4 degrees), in turn, reduces the filtration efficiency.
The reverse osmosis filter is friendly to allergy sufferers and young children
The filters retain allergens and ingredients that irritate the skin. Filtered water is devoid of them, so it will be good for allergy sufferers, patients with atopic dermatitis and for bathing young children, whose delicate skin is quickly irritated.
