The manganese sand filter material produced by our company is made of high-quality manganese sand, which has dense grains, high mechanical strength, strong chemical activity, is not easy to break, and is insoluble in water. It is processed into sand through processes such as water washing, polishing, impurity removal, crushing, drying, magnetic separation, screening, and dust removal, and then the processed manganese sand is mixed according to the grading.
It has the most ideal grading ratio for water treatment filter media, which gives it a specific surface area, pollutant interception ability, oxidation catalytic effect, and minimum backwash loss rate per unit volume. Manganese sand filter media has a black brown appearance, nearly circular, and the main component is manganese dioxide, with a content between 35% and 45%.

Groundwater often contains soluble iron and manganese salts, which affect the chromaticity of water. After appropriate adjustment, the water is sent to the manganese sand filter layer for filtration. Due to the high affinity of manganese sand filter material for divalent iron and manganese, divalent iron and manganese will combine with the filter material, forming precipitate clusters on the surface and continuously accumulating, thereby gradually reducing the iron and manganese content in the water.
