Manganese sand filter is made of high manganese ore as raw material selection and processing. Appearance of rough brown or pale gray, more angular, iron and manganese removal is the best product, manganese sand filter suitable for drinking water in addition to iron, manganese filtration devices. Manganese sand filter technical indicators: Project Analysis Project analysis results of the analysis of manganese dioxide and manganese carbide 18-40% 16-20% 12-22% silica, clay content ≤ 2.25% Fe 8-19% capacity 2.2T / m 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 ore. Manganese sand filter was washed polished 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 which has the best water filter grading scale, making it the largest in the unit volume specific surface area, the strongest interception capability, the largest and smallest catalytic oxidation backwash churn. Manganese sand filter appearance of rough brown or light gray, manganese sand filter commonly used in drinking water in addition to iron, manganese filters, water treatment effect is very good. (Note: MnO2 ≥ 35% either in addition to iron, but also manganese, MnO2 ≤ 30%) can only be used for groundwater iron) and manganese sand filter is mainly used to reduce the water content of iron and manganese, ferromanganese total, according to China drinking water health standards governing its iron content ≤ 0.3 mg / L, manganese content of ≤ 0.1 mg / L, iron manganese content is too high for a long time drinking water will seriously affect their health. manganese sand filter works with the Fe2 + state worked underground (well) water, the water has heterochromatic smell, while reducing pollution ion exchange resin exchange capacity, generation after prolonged iron scale, the impact of heat, can corrode equipment. The manganese sand of MnO2 and Fe2 + redox reaction, Fe2 + into Fe3 + and generate Fe (OH) 3 precipitate, thus the use of manganese sand filter backwash function to achieve removal of purification purposes. Manganese sand filter for removing iron and manganese from groundwater natural manganese sand filter, which should form manganese oxide, manganese-based. Manganese content (with MnO2, the same below) shall not be less than 35% of the natural manganese sand filter, both for groundwater in addition to iron, but also for groundwater manganese; manganese content of 20% to 30% of the natural manganese sand filter, it should only be used groundwater iron; manganese content of less than 20% of manganese ore is not used. Should give priority to productive use through scientific tests or proof to get a good addition to iron and manganese species except natural manganese sand filter effects make. An average density of natural manganese sand filter is generally within the range of 3.2g/cm3 to 3.6g/cm3. Density, except for the use of special requirements. Natural manganese sand filter hydrochloric acid soluble rate should not exceed 3.5% (percentage by mass, the same below). Natural manganese sand filter crushing and wear rate and the rate should not exceed 3%. Natural manganese sand filter should be free of visible dirt, shale and foreign debris, mud content should not exceed 2.5%. The media should be free of water extract toxic to humans and harmful substances. Manganese sand filter common specifications :0.25-0 .5 mm 0.5-0.8mm 0.8-2.0mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm special specifications can be processed in accordance with user needs. Manganese sand filter uses: 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 catalytic surface "active filters" formed to further enhance the effect of iron. Iron and manganese sand filter water through aeration, the only one by natural manganese sand filter, you can complete the entire process in addition to iron. Manganese sand content selection manganese sand filter is running in addition to iron and manganese filter, the water covered the first low-priced iron and manganese ions adsorbed manganese sand filter, which is then oxidized and hydrolyzed to form hydrated hydroxide molecules [Fe (OH ) 3XH2O] and [Mn (OH) nXH2O] active membrane formation, and as a new catalyst for participation in contact oxidation reactions with the use of the active membrane thickening trend has formed a self-healing properties of manganese sand overlying , using the one-year follow-manganese sand, manganese content increased by 18.2%, an increase of 4.8% iron content; using two and a half increased by 27.3% manganese content, iron content increased by 14.3% manganese sand bulk density is low (1.55 to 1.60. g/cm3), especially for medium-sized water filter and siphon addition to various types of iron and manganese in addition to iron and manganese filter backwash tank siphon filter due to the lower head is often not advisable to use a larger density of natural manganese sand filter (Its density is generally 2.2 ~ 2.4g/cm3), so that in addition to medium-sized iron and manganese water filter is designed for use subject to certain restrictions.
