The editor of Yuanlai Jun learned that a resident reported that when making soy milk with well water at home, the result was not soy milk but a mixture of layered water and some insoluble substances. However, the same beans could be made into soy milk with the tap water from a neighbor's house.

　　In response to this strange inquiry, the municipal prevention and control department conducted a water quality test on the well water in the village, thus revealing the mystery that well water could not be used to make soy milk. Does everyone know what the reason is?

　　According to the test results, the total hardness and nitrate nitrogen of the water quality have seriously exceeded the standard, among which the total hardness is720mg/LIt exceeds the national standard270mg/L; The test result of nitrate nitrogen is96mg/LIt is close to exceeding the national standard5Double. According to relevant analysis by the municipal disease control center, the reason why this water cannot be used to make soy milk might be related to the excessively high hardness of the water. Explanation: The hardness of water refers to the content of calcium and magnesium ions in water. If the hardness is too high, the calcium and magnesium ions in water will combine with the protein in beans to form some insoluble substances, and then separate from the water to make soy milk.

　　As is well known, water is of vital importance to human health. It is a minor issue that well water cannot be used to make soy milk, but drinking such water quality for a long time is worrying. It is explained that the hardness of water plays a good role in maintaining the calcium-magnesium balance of the body. However, excessive hardness has adverse effects on the body: on the one hand, it may cause gastrointestinal dysfunction, resulting in temporary symptoms such as abdominal distension, excessive flatulence, and diarrhea, which are considered "water and soil incompatibility"; on the other hand, it makes people more prone to kidney stones and gallstones.

　　"Hard water" also brings a lot of trouble to life. For instance, when boiling water with "hard water", over time, a thick layer of yellowish-white scale will deposit at the bottom of the kettle and thermos. When washing clothes with it, the calcium and magnesium ions in the water cause the soluble soap to turn into insoluble calcium stearate precipitate, thus depriding the soap of its decontamination ability. When cooking with "hard water", the vegetables are less likely to become soft. If there are too many calcium or magnesium ions in water, the combination of calcium or magnesium with sulfate ions will make the water taste bitter.

　　The engineers of Beijing Yuanlai Water Treatment Company kindly remind: It is very important to be cautious when drinking water, especially for self-provided water sources in rural areas, urban-rural fringe areas, and urban enterprises and institutions, such as self-drawn Wells and reservoirs. Before using them as drinking water, it is necessary to have them tested by units with water quality inspection qualifications for relevant items to avoid unnecessary risks and ensure your health.

　　Therefore, for everyone's health, it is recommended to install water softening equipment to remove calcium and magnesium ions from water, reduce water hardness, and improve the quality of life and the health of drinking water. In terms of industrial production, it is equipped with a complete set of large-scale industrial water softening equipment to ensure the quality standards of industrial water, enhance production capacity and product quality. It can provide convenient water for boiler production, pretreatment devices of pure water equipment, and domestic water in hotels and schools.

　　In the water treatment industry, the well water treatment equipment we often equip usually includes main devices such as water inlet devices and water distribution systems.

　　The working principle of well water softening equipment: The hardness of water is mainly determined by the cations in it: calciumCa2＋MagnesiumMg2＋Ionic composition. When the raw water with hardness passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are released. Thus, the water flowing out of the exchanger is softened water with the hardness ions removed. When the resin adsorbs calcium and magnesium ions to a certain saturation, the hardness of the effluent increases. At this point, the water softener will automatically carry out the regeneration work of the exhausted resin according to the preset program. By passing a higher concentration of sodium chloride solution (brine) through the resin, the exhausted resin is restored to the sodium type resin.

　　Well water softening equipment is a method that uses ion exchange resin to reduce or nearly completely remove the content of calcium and magnesium ions in water, thereby reducing water hardness and preventing scale deposition. The resin is regenerated when it has adsorbed a certain amount of calcium and magnesium ions. Use saturated brine to replace the calcium and magnesium ions in the resin, restore the resin's softening exchange capacity, and discharge the waste liquid.

　　Outside the filter, there are various necessary pipes and valves, etc. Mechanical filters are commonly made of fiberglass reinforced plastic, stainless steel or carbon steel with anti-corrosion coating on the tank body. The general process of the well water treatment equipment produced by our company is: raw water booster pump→Multi-media filter→Active filter→Ultrafiltration and multi-media filters are used to remove suspended solids from water, while activated carbon filters can adsorb abnormal colors and odors in water.

　　In many rural areas of our country, due to the scarcity of surface water sources and the severe pollution of water sources by the environment, people are accustomed to digging a well for domestic water use. Tests have shown that the underground well water contains a large amount of mineral ions, such as lead, cadmium, calcium, magnesium and other ions, as well as microorganisms like Escherichia coli, which are seriously excessive. Moreover, the hardness of the water (referring to the hardness in water)Ca2+,Mg2+The plasma level is extremely high. Long-term consumption of well water with seriously excessive heavy metals and other substances can lead to the occurrence of various chronic diseases and infectious diseases, such as gastroenteritis and infectious hepatitis. In daily life, heating with hard water can cause scaling on components such as the pot layer, water heater and solar pipes. After scaling, not only does it consume about1/3The above-mentioned fuel also causes the heating appliances to be unable to be used normally and brings hidden dangers.

　　According to chemical analysis, lead is contained in every gram of scale12Milligrams, arsenic21Milligram, mercury44Milligrams, cadmium3.4Milligram, iron24Milligrams are extremely harmful. They not only cause excessive heavy metal content in the human body but also lead to kidney stones, gallstones, and even cancer and poisoning. Long-term consumption of high-hardness water is the main cause of the incidence of kidney stones and gallstones. If you wash clothes with hard water, not only will the soap not foam easily and lose its stain-removing ability, but it can also make the fibers hard and brittle, thus damaging the clothes. After taking a bath with highly hard water, the hair and skin feel tight, which harms the skin and accelerates its aging. It is especially harmful to infants and young children.

　　In addition, domestic and international investigations have confirmed that the hardness of drinking water is directly proportional to the mortality rate of cardiovascular diseases. The "Household Well Water Purification Pure Water Machine" developed and produced by our company after years of research and development is a scientific and ultra-environmentally friendly water treatment process. It adopts three methods: multi-media filtration, softening and deep filtration, which can effectively remove suspended solids, organic matter and heavy metals from well water. It also has a certain removal effect on some pathogens and microorganisms. Softening can thoroughly remove calcium, magnesium and other ions in water, making the water quality more in line with the standards for human domestic water use. It is an ideal water purification device for the majority of well water applications. This product is easy to install and operate, can continuously discharge water, has no energy consumption, causes no environmental pollution and incurs no maintenance costs.
