Yuxin manganese sand filter is the use of domestic quality, grain dense, high mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese sand. It looks dark brown, nearly round, the main ingredient is manganese dioxide The content of between 35% -45% manganese sand filter is made of natural manganese sand or manganese ore as raw material, crushing process, repeated screening, processed into different content of manganese sand filter appearance of rough, brown, Good iron and manganese functions, is the ideal product for water supply and drainage industry.
Manganese sand filter physical and chemical properties analysis:

Iron content of about 20% hydrochloric acid soluble rate% (3.5
Clay content% (2.5% ≤1.0 wear rate
Density g / cm3 2.66 MnO2% 30-40
Bulk density g / cm3 1.85 Broken rate% ≤1.0
Manganese sand filter uses
Natural manganese sand iron is a contact catalytic iron removal process, the iron content of less than suitable for groundwater in addition to iron 20mg / L of divalent iron oxide and manganese can water high natural manganese sand containing ferric iron, at the same time formed on the surface catalysis of 'active membrane', to further improve the iron effect after iron water aeration, only once by the natural manganese sand filter, you can complete the entire process in addition to iron.
