Manganese sand is mainly used to reduce the water content of iron and manganese, ferromanganese total, according to our drinking water health standards for its iron content ≤ 0.3 mg / L, Mn ≤ 0.1 mg / L, iron manganese content over a long drink High water will seriously affect their health; For textile, food industry products will generate spots; production equipment corrosion ability. Manganese sand filter manganese sand filter with manganese ore as raw material, crushing, screening and other processing. Appearance of rough brown or light gray, commonly used in drinking water in addition to iron, manganese filters, water treatment effect is very good application areas: mineral water, pure water, deionized water pretreatment production line in addition to iron and manganese precipitate, and geothermal projects The pre-treatment and swimming pool project in addition to iron and manganese. How it works: iron to Fe2 + state was underground (wells) in water, the water has heterochromatic odor, pollution and reduce ion exchange resin exchange capacity, long after the formation of iron scale, affecting heat transfer, 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 the purpose of removal of purification. I plant the production of manganese sand filter is currently the best in addition to iron and manganese filter, and its manganese content of 30% or more, high mechanical strength, chemical stability, long service life, welcomed by users. Products are sold in Shandong, Jiangsu, Hebei, Tianjin, Beijing, Hubei and other parts of the city and factories, military units, schools and other enterprises, in addition to iron and manganese structures used. After I plant the production of manganese sand filter filtered water, the age of 3 years, the water quality: iron <0.3mg / L; manganese <0.1mg / L; manganese sand is a natural underground resources, with the exploitation of the time and the needs of the market, in the market value of the increasingly been reflected. Manganese sand is the choice of lump ore and natural sand as raw material, crushing screening processed. Appearance of rough, brown, has a good function in addition to iron and manganese is the ideal product for water supply and drainage industry.
