Iron and manganese are essential trace elements for human body. Iron deficiency in human body can lead to diseases such as iron deficiency anemia, which directly affects health. The iron and manganese needed by human body mainly come from food and drinking water. It is generally believed that too much iron and manganese is harmless to human body, but in China, iron and manganese are only used as sensory indicators.
However, too much iron in water can also cause harm. According to the determination, when the iron content in water is 0.5 mg/L, the chromaticity can reach more than 30 degrees, and when it reaches 1.0 mg/L, not only the chromaticity increases, but also it has obvious metallic taste.
When the concentration of iron and manganese exceeds a certain limit, reddish-brown sediments will be produced. In life, yellow spots can be left on white fabrics, water utensils and sanitary ware, and it is also easy for iron bacteria to multiply and block pipelines.
Excessive iron and manganese in drinking water can cause loss of appetite, vomiting, diarrhea, gastrointestinal dysfunction and abnormal stool. According to the research of American and Finnish scientists, too much iron in the human body has an effect on the heart, even more dangerous than cholesterol. Therefore, high-iron and high-manganese water must be purified before drinking.
The key to iron and manganese removal in drinking water is aeration oxidation. You can buy a magnetizing device specially used to purify drinking water. Magnetized water can significantly promote the oxidation of low-valent iron and manganese, and it is obvious that magnetized water is beneficial to iron and manganese removal.
