Manganese sand filter is a contact catalytic iron iron removal process, suitable for groundwater iron content is less than 20mg / L of iron. Natural manganese sand containing water of high manganese can divalent iron to trivalent iron oxide, while the catalytic surface is formed of the "active membrane", to further enhance the effect of removing iron. Iron water through aeration, and only after a natural manganese sand filter, will be able to complete all the process of iron removal. Manganese sand filter is the use of domestic quality, grain density, mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese ore. After washing polishing cleaning, drying, magnetic separation, screening, dust and other technology into the sand. Manganese sand then processed by a certain gradation blending. It has a water filter ideal grading scale, it has the largest volume in the unit specific surface area, the strongest interception capacity of the largest and smallest catalytic oxidation backwash churn. Manganese sand filter is widely use: manganese sand filter appearance of rough brown or light gray, commonly used in drinking water in addition to iron, manganese filters, water treatment effect is very good. (Note: MnO2 ≥ 35% either in addition to iron, but also manganese, MnO2 ≤ 30%) can only be used for groundwater in addition to iron) manganese sand filter mainly used to reduce the water content of iron and manganese, ferromanganese total, according to China drinking water standard gauge its iron content ≤ 0.3 mg / L, Mn ≤ 0.1 mg / L, iron manganese content is too high for a long time drinking water will seriously affect their health.
