Manganese sand filter media is made from high-quality manganese sand ore, featuring dense grains, high mechanical strength, and strong chemical activity. It is insoluble in water and processed through washing, grinding, impurity removal, crushing, drying, and magnetic separation.
It offers an ideal gradation ratio for water treatment, providing the largest specific surface area and strongest interception capacity. The dark brown granules typically contain between 35% and 45% manganese dioxide.
Common Sizes: 0.25-0.5mm, 0.5-1.0mm, 1.0-2.0mm, 2.0-4.0mm, 4.0-8.0mm, 8.0-16.0mm. Custom sizes available.
