Manganese sand filter materials Manganese sand filter material appearance rough brown or light gray, suborbicular, ingredient is manganese dioxide, content is between 35% and 45%. Use it to deal with groundwater, simple technology, convenient operation, cover an area of an area small, low engineering cost, long-term stability, the service period in 5 years, easy management, do not add any chemicals to remove the harmful material such as fe, mn, arsenic water, the purpose of the water quality fully meet the national drinking water standard, groundwater is a very good filter material processing. Manganese sand filter materials are using high quality domestic manganese sand, grain density, mechanical strength, strong chemical activity, not easily broken, insoluble in water, natural manganese ores. After the water washing grinding in removing impurity, crushing, drying, magnetic separation, screening, dust removal process into sand, etc. Then processed manganese sand according to certain gradation blending. It has the ideal water treatment filter, grading scale, making it in unit volume, specific surface area of the largest, the most powerful section carrying capacity, the catalytic oxidation of the largest and the smallest backwash turnover. Manganese sand filter materials used in the iron and manganese removal of domestic and drinking water filter device, the filtering effect is very good. Manganese sand filter material is mainly used to reduce the total iron, ferromanganese and manganese content in the water, according to china's domestic and drinking water hygiene standard gauge its iron long drink water containing high iron manganese content will seriously affect health.
