Jug filtration systems. How do they work?

When detached from the tap water and poured it into a jug filter, often wondering what makes a moment later becomes clear. This filter cartridge - This small sewage water inside the jug. Discover the secrets of its operations.

The whole secret lies in the filter. It is here that there are carefully chosen and regularly inspected bed filtration. It consists of activated charcoal (activated carbon) and the ion exchange resin (ion exchange resin).

Activated charcoal, which stop harmful substances and unpleasant odors.

Coal is a component of natural origin. It is obtained by heating wood pulp to a temperature of 900 ° C. The product, after rinsing, for example, activates the water vapor, resulting in a network of pores. With this microporous structure has a very developed area that is active against a small weight. For example, one gram of activated carbon has a total active area of 500 to 2500 m2. It takes more than 13 pitches for basketball!
The porous structure of carbon makes it acts like a sponge brilliant. Ideally adsorbs many compounds, which flows along with water through the pipes. In practice, this means that it contains harmful substances, after contact with activated carbon shall be permanently attached to its surface. During the process of filtering water flowing through the filter bed is deprived of a fair proportion of the Mendeleev table: harmful substances such as chlorine and heavy metals (lead, cadmium, copper, nickel, mercury), as well as certain pesticides (occurring substances in plant protection products) organic compounds (eg phenols) and polyvinyl chloride used, inter alia, for the production of PVC pipes. Eliminating all of these pollutants is precisely through their surface molecules binding to the solid particles or coal.

Thanks to such properties, activated carbon is widely used in many industries. It is used to include in the food industry, pharmaceutical (adsorb poisons in the gastrointestinal tract, which prevents their absorption), and household appliances domowego.Herbata with filtered water. In the latter case, activated carbon is to absorb odors. It is used therefore pochłaniaczach odors in refrigerators and kitchen eaves. Also during the process of water filtration, eliminating the harmful substances is eliminated odor caused by it.
Ion exchange resin, which is the end of the stone

The second component involved in water filtration system is dzbankowym ion exchange resin. Thanks to the water that is obtained by a filtering process, it is soft. As activated carbon has a porous structure. It is a synthetic product, which operate in a nutshell is the ion exchange bad for good. He works as a ruthless selector: pick up from the water ions of calcium and magnesium salts, and in their place introduces other. Why calcium and magnesium salts? They are in fact the cause of the accumulation of the banes of the heating elements in kettles and other appliances: a burdensome mineral sediment, ie. limescale.

The whole process of chemical water softening by ion exchange resin is quite complicated. His exact description would require the use of the wording of many professional in the field of chemistry. For the first time using a water softening ion exchange resin took place over a hundred years ago (did so in 1905 R. Gans). It is worth mentioning that the ion-exchange resins have great merit, not only in drinking water treatment, but also. in reducing cholesterol levels. For years, are used for the treatment of hypercholesterolemia.

Not all ion-exchange resins are equal. Some of the hardness of the water removal process may cause undesired lowering of the pH, making the water becomes acidic. Therefore, when choosing dzbankowych filtering systems should pay attention to it.

DAFI, a healthy choice

DAFI filtration systems do not cause acidification of water. They used high-quality ion exchange resin provides the water pH to remain at the appropriate level (normal 6,5-9,5). Guarantee safety in the use of seals of approval is confirmed by NIH, and regular laboratory tests.

The production process cartridges DAFI takes place in sterile conditions. In addition, the contribution before packaging is subject to steam sterilization. Silver impregnation of activated carbon filter protects the interior against the development of microbes for a whole month from the date of first use.

Water System DAFI treated soil is subjected to a mechanical filtering on a special woven. Are retained at this stage, impurities such as sand, rust, which wypłukiwanymi secondary pollution from the installation of steel water pipes during transport.

The materials from which the pot is made, have all necessary certificates (NIH, LGA and the positive reviews of the Institute of Mother and Child), allowing for contact with food. Pitcher filter cartridge and form an integral whole. Contributions should be placed in a special hole on the jar funnel, pour the water and wait a few minutes, until the flows through the filter and accumulates in the jug. I drink - cheers!
