: , Song Dynasty First of all, why should we choose < : <: Manganese sand filter material
: , Song Dynasty In daily life, due to the excessive iron and manganese elements in the water, the water quality is too hard and cannot meet the national standards. Drinking water standards. Drinking water with excessive iron and manganese content for a long time will seriously affect your health and affect the normal life of residents. In the industrial production process, if the industrial water contains excessive iron and manganese elements, the boiler tubes will be scaled and rusted, which will cause the equipment's thermal conductivity and mass transfer performance to drop sharply, increasing power consumption and maintenance costs. Invisibly increased investment. Therefore, on the one hand, in order to meet the standard of normal drinking water for residents, and on the other hand, in order to save the capital investment of industrial and mining enterprises, we must soften the hard water containing iron and manganese elements that exceed the standard!
: , Song Dynasty Secondly, < : <: Manganese sand filter material
Why can it achieve the purpose of removing iron, manganese and softening water
: , Song Dynasty manganese sand filter material is made of dense grain density It is not easily broken, has high mechanical strength, high compressive strength, and is made of high-quality manganese sand with high price and high manganese content. After processing, it is blended according to the most ideal grading ratio. The purpose of this blending is to enable the manganese sand to have the largest specific surface area in unit volume to contact the iron and manganese elements in the water, and to have the strongest physical and mechanical interception of pollution. Ability to achieve efficient oxidation catalysis and minimal backwash loss rate, saving energy and reducing capital investment. Natural manganese sand with high manganese content has a rough brown or light gray appearance. Manganese sand filter material is often used in iron and manganese removal filtration devices for domestic drinking water and industrial circulating water. Iron exists in the underground (well) water in the state of + and is easily oxidized. High-valent manganese has a strong oxidizing effect and undergoes a redox reaction with + to oxidize + into +. + forms an insoluble precipitate attached to the On the surface of the manganese sand filter material, these precipitates are removed with the water flow under the backwash function of the manganese sand filter tank, thereby achieving the purpose of softening the water quality.
: , Song Dynasty Third, how to enhance the iron and manganese removal effect of < : <: Manganese sand

: , Song Dynasty The previous article said that natural manganese sand can oxidize divalent iron in water into trivalent iron. At the same time, a catalytic "active filter membrane" is formed on the surface of the manganese sand. In order to ensure that the active filter membrane can continue to function, the manganese sand filter tank must be backwashed in a timely manner to ensure that the surface of the manganese sand is not scaled. In order to further enhance the iron removal effect, an aeration treatment process is added before the manganese sand filter tank to oxidize low-valent iron ions into high-valent iron ions. The high-valent iron ions are oxidized into ferric ions to form precipitation. Finally, the iron-containing water is only processed through natural processes. Once the manganese sand is filtered, the entire iron removal process can be completed.
