manganese sand
Product Details
Manganese sand filter material is made of high quality natural manganese ore, its appearance is brown, and it has a unique effect on removing iron and manganese filtration in groundwater. Manganese sand filter materials are made of high-quality manganese ore,large mechanical strength, strong chemical activity, not easily broken and insoluble in water. After washing, sanding, impurity removal, crushing, drying, magnetic separation, screening, dust removal and other processes into sand. Then, the processed manganese sand is adjusted according to a certain gradation. It has the best gradation proportion of the water treatment filter material, so that it has the largest specific surface area, the strongest sewage interception capacity, the largest catalytic oxidation effect and the minimum backwash loss rate in the unit volume. Manganese sand filter appearance black brown, nearly round, the main ingredient is manganese dioxide, the content is between 35%-45%. The manganese sand filter for groundwater treatment, simple process, convenient operation, low cost, long-term stability, the service cycle in 5 years, easy to manage, do not add any chemicals to water to remove iron, manganese, arsenic and other harmful substances, water quality fully meet the national standards for drinking water, groundwater treatment is very good. In the water softening process, first of all, the processing time of manganese sand softened water is limited. Secondly, due to the water elemental iron, ferric oxide, ferrous oxide, iron oxide, material mixing, the iron and manganese removal effect of manganese sand, water softening effect is greatly reduced, so in order to increase the removal of iron and manganese manganese sand the effect will be in the manganese sand treatment process before a aeration is iron and manganese removal to achieve the best effect!
