Manganese sand filter material is used in domestic high quality manganese granule, grain density, mechanical strength, chemical activity strong, not easy to break, insoluble

Natural manganese ore in water.It is washed and removed by washing, crushing, drying, magnetic separation, screening, dust removal and other processes.Then the processed manganese sand is adjusted to a certain level.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.[1]
Manganese sand filter material appearance is black brown, nearly circular, main component is manganese dioxide, content is between 35%- 45%.
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.

Iron to Fe2 + state was in underground water (well), the water is Harmonia odor, pollution ion exchange resin and reduce the exchange capacity, long time after the formation of iron scale, heat effect, can corrode equipment. Manganese content (in terms of MnO2, similarly hereinafter) shall not be less than 35% of natural manganese sand filter material, which can be used for groundwater iron removal and for groundwater manganese containing manganese content is 20% ~ 30% of natural manganese sand filter material, should be used only for groundwater iron removal; manganese content is less than 20% of the manganese sand is not used. It is advisable to adopt the scientific experiment or production and use to prove that the natural manganese sand varieties with good iron removal and the removal of manganese can be used as filter material.
