Rigid water and methods to combat it
Our body more than half consists of water. Therefore, our health depends on the quality of life-giving moisture that we consume.
Water hardness is an indicator of the amount of calcium salts dissolved in it andmagnesium. Groundwater, passing through the calcareous rocks, dissolves the mineral substances. In large cities, chlorine is added to this. There are many methods for determining the rigidity of water using instruments and observations. If the scum is quickly collected in your kettle, then you have hard water at home. You need to use a water softener when operating the washing machine and dishwasher. But calcareous deposits are also formed in the pipes of water supply, because of which the water pressure decreases markedly. In hard water poorly washed white things, and the skin on the face after washing is pulled together. Lately there has been much talk about the dangers of hard water for human health. For example, that stones in the kidneys - is the effect of high content of calcium salts. Skin peeling, deterioration of hair quality, dysbacteriosis and other digestive diseases - all this is the result of drinking hard water. Hard water has a bad effect on plants. Therefore, it is recommended to water them, which was defended for several days.
Hard water is a problem for fans of aquariums. It is not tolerated by some fish and aquatic plants. The best water for aquarium AQUAXER Water Osmos - it is cleaned from nitrates, phosphates, heavy metal salts, pesticides. It is good to dilute the water in the aquarium.
Purified hard water in many ways. The easiest way is to bring it to a boil or freeze for a long time. In this case, the ions of the salts decompose, and the water becomes clean. Another way is to filter. Passing through the filter, the molecules of the magnesium and potassium salts react with the molecules of the ion exchange resin, the metals remain in the filter and the water is purified. From time to time, the filter should be washed with a solution of common salt to cleanse the magnesium and potassium that has accumulated in it.
Water can be mitigated by chemical reaction. Lime or soda, getting into the water, react with the salts of potassium and magnesium and form strong compounds that settle on the bottom in the form of a precipitate. The remaining water becomes clean.
At present, a lot of water filters are produced. Whole cleaning systems have been developed, which are installed in the kitchen, and before getting into the mug, the water is cleaned. By methods of cleaning they are divided into:
- sorption (in other words, absorbers);
- mechanical, sand particles trapped in water, debris, flakes;
- ion-exchange, oxidizing compounds in the water, and transferring them into new forms;
- electrochemical, with the help of oxidation-reduction process, destroying viruses, bacteria, etc .;
- reverse osmosis - the most promising. They pass through the semi-impermeable minute membranes only molecules of water and oxygen.
Everyone can choose a filter for himself, which is more suitable in his case. Also safe is bottled water, the delivery and sale of which is not a problem nowadays.
