Manganese sand filter is the use of domestic quality, grain density, high mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese sand. After washing polishing cleaning, drying, magnetic separation, screening, dust and other technology into the sand. Then processed by a certain level of manganese sand with blending. Manganese sand filter water filter has the best ratio of gradation, making it in the unit volume has the largest surface area, the strongest interception capability, the largest and smallest catalytic oxidation backwash churn. Manganese sand filter appearance of rough brown or light gray, commonly used in drinking water in addition to iron, and manganese removal filters, water treatment effect is very good. Manganese sand filter is mainly used to reduce the total content of iron and manganese in the water, our "drinking water standards", the iron content in drinking water should not exceed 0.3mg / L, manganese content of not more than 0.1mg / L, more than You must be addressed. Therefore groundwater iron, water colors that change occurred after the manganese content exceeded, will give life and production of water will cause a great impact. Natural manganese sand iron is a contact catalytic iron craft, suitable for groundwater iron content of less than 20mg / L of iron. High manganese natural manganese sand containing water can divalent iron into ferric oxide, while the surface catalysis "active membrane" formation, to further improve the iron effect. Iron water after aeration, only once by natural manganese sand filter, you can complete the entire process in addition to iron. Common Specifications: 0.4-0.8mm 0.5-1mm 0.8-1.2mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm manganese sand filter due to low intensity, generally not recommended to use too small models, special specifications can be customized demand further processing.
