The water that exceeds the standard of iron and manganese is generally groundwater or well water. Conventionally, iron and manganese are present in the underground (well) water at almost the same time. When the iron content in the water is high, the water has an iron smell and affects the taste of the water. Production water such as textile, textile, printing and dyeing, chemicals, and leather refinement will reduce product quality. Iron-containing water can cause rust stains on production equipment, yellow or brownish yellow stains on laundry, iron deposits Fe2O3 will grow iron bacteria, and block pipes. Sometimes red water appears. Water with a high manganese content is similar to the case with high iron content. If the water is colored, smelled, and tasted, and the quality of industrial products such as textiles, papermaking, brewing, and food is impaired, household appliances will be contaminated into brown or black. Washed clothes will have slightly black or light gray stains.

    Manganese sand filter is also called iron and manganese removal filter. Manganese sand filter (iron and manganese removal filter) is mainly manganese sand filter and iron and manganese removal filter. It uses oxidation method to oxidize low-priced iron ions and low-priced manganese ions in water. Into high-valent iron ions and high-valent manganese ions, and then filtered through suction to remove the iron and manganese content in the water. The choice of manganese sand filter media is very important. It is related to the ability to remove iron and manganese. Generally speaking, the manganese content of manganese sand is 30%, so this manganese sand filter (except iron manganese filter) can produce water. Iron in water, if the content of manganese is 35%, then this manganese sand filter can remove iron ions in water and manganese ions in water. Note: ordinary quartz sand filters, activated carbon filters and precision filters can only remove A small amount of iron and manganese ions in water is much less than the removal ability of manganese sand filters
