Water hardness is presence at it of insoluble compounds of salts of manganese of calcium with the basis of carbonic acid (hydrocarbonates). That will get rid of water hardness, it is necessary to remove from it salts. There are several ways.
Instruction
1. Vymorazhivany the vodyvymorazhivaniye is applied mainly to make water fresh, i.e. to remove from it excess of salt. The way is based on regularity it that if clear water, then freezes it at lower temperature, than that water which contains salts. All city dwellers are familiar with this regularity – to avoid ice, roads salt. If you need to purify water from salt, then freeze it in the deep freeze. At the same time clear water will freeze in the beginning and if to consider ice crystals, then between them there has to be "brine" (mix of salts and waters). Merge this brine, without waiting when it freezes. Collect pure ice and kindle it, you have to receive clear water without impurity of salts. But if you began to freeze water at once at very low temperature, then both water, and brine can freeze at once. Therefore pick up necessary temperature in the freezing chamber. But on the other hand, if water is absolutely deprived of salts, then it cannot be useful. It is necessary to have for human health in water of salts.
2. Other way to get rid from soleyprokipyatita water in open vessel, but it is necessary to boil so that it boiled minutes 25 - 20. In this case from water the organic compounds having lower boiling temperature disappear. All the familiar scum, is that other as rigidity salts. Before boiling of salt have been dissolved in water. After salt boiling (carbonate rigidity) are removed, water becomes softer. But boiling, besides, leads also to reduction in water of salts of calcium and magnesium which are necessary for human body. This way is good also the fact that at temperature of 100 degrees large number of pathogenic bacteria perishes.
3. Cleaning with the help to filtrakupita the filter where activated carbon, more precisely karbonblok is used. Karbonblok is new technology achievement with use of the activated coals. Receive karbonblok from powder of activated carbon. This powdery mix mixes up with well crushed polyethylene. Mix is heated, and there is agglomeration (parts of coal stick together with polyethylene among themselves). As a result the monolithic product having good sorption characteristics turns out. Such dense structure detains very scanty particles, to several microns.
