Manganese sand filter material is mainly used for groundwater iron and manganese removal filter, the product is made of natural manganese sand or manganese ore raw materials, the screening of different manganese sand filter materials processed into content. Spherical, brown appearance, has the good performance of iron and manganese removal. As the manganese form of manganese sand filter materials are mainly composed of manganese dioxide. According to different processing purposes, choose different content of products, with MnO2 content not less than 35% of manganese sand filter material can be either manganese removal, and in addition to iron, MnO2 content less than 30%, only appropriate groundwater in addition to iron.
