Manganese sand filter material use Chinese high quality manganese placer with characteristics of high grain density high mechanical strength high chemical activity not easy to break and insoluble in water etc.
Features:
Manganese sand for filter material is black brown, nearly round, the main ingredient is manganese dioxide, the content is between 35%-45%. It use Chinese high quality manganese placer with characteristics of high grain density, high mechanical strength, high chemical activity, not easy to break and insoluble in water, etc.
Manganese sand final products are after washing, grinding and removing impurities, crushing, drying, magnetic separation, screening, dust and other processes.Then the processed manganese sand is blended according to a certain grade.It has the optimal gradation ratio of water treatment filter material, so that it has the maximum specific surface area per unit volume, the strongest sewage interception ability, the maximum oxidation catalysis and the minimum backwash loss rate.
