Our body is more than half composed of water. Therefore, our health depends on the quality of the life-giving moisture that we consume.
Water hardness is an indicator of the amount of calcium salts dissolved in it and
magnesium.
Groundwater, passing through calcareous rocks, dissolve mineral substances in itself. In big cities, chlorine is added to this. There are many methods for
determining water hardness using instruments and observations. If your kettle is quickly going to scale, then you have hard water at home. You need to use a water softener when operating a washing machine and dishwasher. But calcareous deposits are also formed in water supply pipes, due to which the
water pressure is noticeably reduced. In hard water, white things do not wash well, and the skin on the face contracts after washing. Recently, much has been said about the dangers of hard water for human health. For example, that kidney stones are the effect of high calcium salts. Peeling skin, deterioration of hair quality, dysbiosis and other digestive diseases - all this is the result of drinking hard water. Hard water affects plants badly. Therefore, they are recommended to be watered with water that has settled for several days.
Hard water is a problem for aquarium lovers. Some fish and aquatic plants cannot tolerate it. AQUAXER Water Osmos aquarium water is best suited - it is free from nitrates, phosphates, salts of heavy metals, pesticides. It is good to dilute the water in the aquarium.
Hard water is purified in many ways. The easiest way to bring it to a boil or freeze for a long time. In this case, the salt ions decay, and the water becomes clean. Another way is filtering. Passing through the filter, the molecules of 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 needs to be washed with a solution of sodium chloride to cleanse the accumulated magnesium and potassium in it.
Water can be softened by a chemical reaction. Lime or soda, falling into the water, react with potassium and magnesium salts and form strong compounds that settle to the bottom in the form of sediment. The remaining water becomes clean.
Currently, a lot of water filters are available. Entire cleaning systems have been developed that are mounted in the kitchen, and before getting into the mug, the water is cleaned. According to cleaning methods, they are divided into:
- sorption (in other words, absorbers);
- mechanical grains of sand, trash, flakes trapped in water;
- ion-exchange, oxidizing compounds in water, and translating them into new forms;
- electrochemical, using the redox process, destroying viruses, bacteria, etc .;
- reverse osmosis - the most promising. They pass only
molecules of water and oxygen through semi-impervious tiny membranes.
Everyone can choose for themselves a filter that is more suitable in his case. Bottled water is also safe, the delivery and sale of which is not a problem in our time.
