Natural manganese sand filter
1.Description of Manganese sand filter
Manganese sand filter material is made of natural manganese ore as raw material, by crushing, washing, impurity removal, drying, magnetic separation, screening, dust removal and other processes, manganese sand filter material is mainly used in water treatmentfor remove iron and manganese, people process good manganese sand, according to a certain gradation made with water treatment filter material gradation ratio, so that it has the largest specific surface area and sewage intercision capacity in unit volume.
