 I plant the production of manganese sand filter is the best domestic and manganese filter in addition to iron, manganese dioxide content of more than 35%, high mechanical strength, chemical stability, long service life, to get the height of the water treatment industry experts affirmed and recognized. The products are sold in Shandong, Jiangsu, Hebei, Northeast, Tianjin, Beijing, Hubei, Hunan, Anhui, Sichuan, Chongqing, Shanxi, and so on around the city and factories, military units, schools and other enterprises and institutions, in addition to manganese in addition to iron structures . I plant the production of manganese sand filter after filtration of water, the age of 3 years, water quality: iron <0.3mg / L; manganese <0.1mg / L; 

 Natural manganese sand filter is quality natural manganese ore as raw material by crushing screening processed manganese sand appearance of brown, rough surface. Heavy, high hardness, easy to wear, broken, chemical stability, long life, soaked in water insoluble, filtered water, the manganese content increase, natural manganese sand can be said that the most difficult to dissolve in water purifying agent. Has a good addition to iron, and manganese performance, groundwater and industrial water containing iron ions and manganese ions in addition to iron, and manganese processing essential products. Does not contain toxic substances, is a very strong oxidant. Sand manganese from the manganese ions and iron ions of the water oxidation and catalysis can effectively remove iron, manganese composition. Manganese sand is commonly used for removing iron and manganese filtration devices. Has a good addition to iron and manganese function, is the ideal water supply and drainage industry. Natural manganese sand is a very strong oxidant, water divalent iron from oxidation, natural manganese sand containing MnO2 was, it is the Fe2 + oxidized to Fe3 + in natural manganese sand filter, a manganese content (to MnO2) both can be used not less than 35% of the groundwater in addition to iron, can also be used for groundwater and manganese; manganese content of 20% to 30% of natural manganese sand filter, it should only used for groundwater in addition to iron, containing less than 20% is then unfit for use. Natural manganese sand is a strong oxidant, and oxidation of water from the stock iron. Natural manganese dioxide sand in addition to iron, the principle of two kinds: one is the role of the so-called active membrane, manganese sand surface with a layer of strong oxidation. Another is the manganese sand antiferromagnetic catalysis. Catalytic water divalent iron into trivalent iron, then the trivalent iron kHz attached to the manganese sand particle surface and thus play the purpose of removing iron. Natural manganese dioxide can be oxidized in the water of ferrous iron to ferric iron to precipitate removed, and the water clean, and manganese dioxide oxidation of dissolved oxygen in the water of seven-valent manganese oxide. The seven-valent manganese and then the water oxidation of divalent iron into trivalent iron. Natural manganese sand in addition to iron? Kinds of contact with the catalytic iron removal process + is suitable for groundwater iron content of less than 20mg / L of iron removal natural manganese sand with the high price of manganese can water ferrous iron oxidation of divalent iron, formed on the surface of the catalyst's "active membrane" to further enhance the effect of the removal of iron: iron water by aeration, only natural manganese sand filter once, you can complete all the iron removal process.
