Manganese sand filter is the domestic good quality, dense grain, mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese ore. Polished by washing cleaning, drying, magnetic separation, screening, dust and other technology into the sand. Then processed manganese sand with a certain level by blending. It has the best water filter gradation ratio, making it the largest surface area per unit volume, interception in the strongest ability, oxidation catalyst and the smallest backwashing loss rate. The rough appearance of manganese sand filter was brown or light gray, commonly used in drinking water in addition to iron, and manganese filtration devices, the treatment effect is very good. (Note: MnO2 was ≥ 35% either in addition to iron, but also in addition to manganese, MnO2 ≤ 30%) can only be used for groundwater in addition to iron), manganese sand filter used to reduce the total content of iron ferromanganese and manganese in water, according to our drinking water health standards regulation of its iron content ≤ 0.3 mg / L, and manganese content of ≤ 0.1 mg / L, a long time drinking excessive amount of iron manganese water will seriously affect their health. 
 Manganese sand filter uses: natural manganese sand, iron removal is a contact catalytic iron removal process for groundwater iron content of less than 20mg / L of iron removal. The high price of natural manganese sand containing manganese can water oxidation of divalent iron into trivalent iron, the catalytic role of active membrane is formed on the surface, to further improve the effect of iron removal. Iron water by aeration, the natural manganese sand filter once, you can complete all the iron removal process.
