Characteristics:
Manganese sand filter materials are using high quality domestic manganese sand, grain density, mechanical strength, strong chemical activity, not easily broken, insoluble in water, natural manganese ores.After the water washing grinding in removing impurity, crushing, drying, magnetic separation, screening, dust removal process into sand, etc
It has the ideal water treatment filter, grading scale, making it in unit volume, specific surface area of the largest, the most powerful section carrying capacity, the catalytic oxidation of the largest and the smallest backwash turnover.
Appearance:
Manganese sand filter material appearance of dark brown, suborbicular, ingredient is manganese dioxide, content is between 35% and 45%.
Appification:
Using manganese sand filter material processing of groundwater, the craft is simple, convenient operation, low engineering cost, long-term stability, the service period in 5 years, easy management, do not add any chemicals to remove the harmful material such as fe, mn, arsenic water, the purpose of the water quality fully meet the national drinking water standard, groundwater is a very good filter material processing.
The current use of natural manganese sand deferrization principle has two kinds: one kind is manganese sand surface with a layer of active filter membrane, has the very strong oxidation;Another is catalytic effect to the iron and manganese sand itself will be the bivalent iron catalyst into ferric iron in the water, and the third order iron attached to manganese sand particle surface, thus attaining the goal of iron.Content is 30% natural manganese sand filter materials, only suitable for groundwater in addition to iron.
