Description of Manganese Sand
Manganese sand filter material is made of high-quality manganese sand ore, with dense grains, high mechanical strength, strong chemical activity, not easy to break, and insoluble in water. It is processed into sand by washing, grinding, impurity removal, crushing, drying, magnetic separation, screening, dust removal and other processes. Then the processed manganese sand is blended according to a certain gradation. It has the most ideal gradation ratio of water treatment filter material, so that it has the largest specific surface area, the strongest interception capacity, the largest oxidation catalysis effect and the smallest backwash loss rate per unit volume.Manganese sand filter material is dark brown in appearance, nearly round, the main component is manganese dioxide, and the content is between 35% and 45%.
Common Size
Hunan Daji Manganese Industry Co.Ltd was established in 1995,located in Leiyang City,Hunan Province,China which is a professional manufacturer specialized in producing manganese series products,including manganese sand,manganese dioxide powder,manganese ore etc.
Application of Manganese Sand
Natural manganese sand is a strong oxidant, which can oxidize divalent iron in water. It is often used in drinking water removal iron and manganese filtration devices, and groundwater removal iron and manganese removal water purification equipment.
The service life of manganese sand is generally 3 to 5 years for groundwater with high iron concentration, and for groundwater with low iron concentration, the service life is longer, and some have more than ten years. In some natural manganese sand filters, the manganese sand on the upper part of the filter layer will gradually form spherical "rust sand", and the surface of the "rust sand" has a layer of "active filter membrane", which still has the ability to contact catalytic iron removal, so the formation "Rust sand" is not a sign of failure of natural manganese sand. When the length of "rust sand" roughly makes the particle size of the filter material too coarse and affects the effect of iron removal, it is necessary to replace part of the filter material. Therefore, we must pay attention to whether there is "rust sand" in our construction process. If so, we must distinguish the size of "rust sand". If it is a small size, it can continue to be used, which can reduce our industrial costs. , If it is a large specification, it must be replaced to avoid affecting the filtered water quality.
