National Hotline :010 -56,420,675. manganese sand filter, the ideal treatment filter media manganese sand filter is the best water filter, because it has a water filter ideal gradation proportion it has the largest specific surface area, per unit volume of the interception capability, the maximum oxidation catalysis strongest and the smallest backwash wastage rate. Manganese sand filter domestic good quality, dense grain, high mechanical strength, chemical activity, not broken, polished purify water-insoluble natural manganese sand, washed, dried, magnetic separation, screening, dust and other craft into the sand, manganese sand then processed at a certain level with blending. Manganese sand filter looks rough brown or light gray, addition to iron, manganese filtration devices commonly used in drinking water, the treatment effect is very good. (Note: MnO2 ≥ 35% both 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 is mainly used to reduce the iron in the water ferromanganese and manganese content, according to China's drinking water health standards governing the iron content of ≤ 0.3 mg / L manganese content of ≤ 0.1 mg / L, for a long time drinking water iron manganese content is too high will seriously affect their health. (1) manganese sand filter Uses: natural manganese sand iron removal is a contact with the catalytic iron removal process, suitable for the the groundwater iron content of less than 20mg / L of iron removal. Natural manganese sand containing high manganese can water bivalent iron oxidized to trivalent iron, have a catalytic active membrane "is formed on the surface at the same time, to further improve the iron removal effect. Iron-containing water by aeration, once filtered through the natural manganese sand, iron removal process can be done. (2) selection of the manganese sand content: run in addition to the iron and manganese filter, low-cost iron and manganese in water first coating co manganese sand filter membrane adsorption, then oxidation and hydrolysis, generate hydroxide hydrated molecules [Fe (OH ) 3XH2O] and [Mn (OH) nXH2O] The formation of the active membrane, and as the catalyst involved in the oxidation reaction, so that the active membrane is formed with the use of thickening tendency, the self-healing properties of the the lamination manganese sand 1.55 to 1.60, lamination manganese sand, manganese content increased by 18.2%, 4.8% increase in iron content; using the two-and-a-half years, the increase in the manganese content of 27.3%, an increase of 14.3% iron content. bulk density, low manganese sand (for g/cm3), particularly suitable for large and medium-sized waterworks siphon large natural manganese sand filter in addition the ferromanganese filter and type in addition to iron and manganese filter tank siphon filter backwash water head lower, often inappropriate to use bulk density (the bulk density is generally 2.2 ~ 2.4g/cm3), subject to certain restrictions on use of large and medium-sized water treatment plant in addition to the ferromanganese filter design.
