Manganese sand iron is a contact catalytic iron removal process, suitable for groundwater iron content of less than 20mg / L of iron. Hydrochloric acid can be dissolved in water application can not acidic. The water of divalent iron into trivalent iron catalysis, then ferric kilohertz manganese sand filter attached to the particle surface and thus play a purpose other than iron. The use of natural sand iron manganese dioxide, the principle there are two kinds: one is the role of so-called active membrane, manganese sand filter surface there is a strong layer of oxidation. The product is a strong oxidant, capable of water from the oxidation of iron stock. Natural manganese sand filter manganese dioxide can oxidize water divalent iron to trivalent iron to precipitate is removed, the water clean, manganese dioxide dissolved oxygen in water is oxidized into heptavalent manganese oxide. Another manganese sand itself antiferromagnetic catalysis. Seven manganese oxide in water and then divalent iron into trivalent iron ferromanganese filter running except when the water covered the first low-cost iron and manganese manganese sand filter adsorption, oxidation and hydrolysis and then manganese sand filter can a few years, born hydroxide hydrate molecules [Fe (OH) 3XH2O] and [Mn (OH) nXH2O] active membrane formation, and as a catalyst for a new intervention oxidation reaction, along with the use of the active filter has thickened The tendency to form a laminated manganese sand self-healing properties, using laminated manganese sand, manganese-year increase of 18.2%, an increase of 4.8% iron content; the manganese content using two half increased by 27.3%, increase in iron content 14.3% manganese sand density is low (of 1.55 ~ 1.60g / cm3), especially for large and medium sized combination of iron and manganese in addition to siphon water filter and various types of iron and manganese in addition to the canister siphon filter backwash head because lower manganese The main component of sand, often inappropriate to use a large density of natural manganese sand filter (whose density is generally 2.2 ~ 2.4g / cm3), so that in addition to Fe, Mn and medium-sized water filter designed for use subject to certain limits. Manganese sand filter is a strong oxidant, can play in water stock iron oxidation. In conventional water treatment processes, the use of aeration plus manganese sand filter filtration to remove dissolved iron and manganese. In this project, taking into account land, investment manganese sand, using the dosing of sodium hypochlorite in water ultrafiltration method to achieve this purpose, an amount of 6ppm. Manganese sand filter washed polish cleaning, drying, magnetic separation, screening, cleaning and other processes. 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. The body's normal intake of iron and manganese sand filter production process is: after washing polished cleaning, drying, magnetic separation, screening, dust and other process into sand, manganese sand filter and then processed by a certain manganese sand graded blending. For causing water turbidity removal of suspended solids with high capacity; product water turbidity usually reaches 0.2NTU less; ultrafiltration to remove colloid or suspension properties of iron, manganese, but can not remove dissolved ferrous ion and divalent manganese ions, it is necessary with the use of an oxidizing agent, the rapid oxidation of ferrous to ferric iron, formed around the neutral pH of insoluble iron colloids, the divalent manganese oxidation of tetravalent Manganese is how many tons of sand a cube, filtered through ultrafiltration removed. The main features of manganese sand filter ultrafiltration membrane separation technology is a high filtering accuracy, the project uses a nominal accuracy of 0.03 micron filter membrane, it can achieve: the main component of manganese sand filter _ Song Xin Xi'an _ manganese sand filter manganese sand provided by Gongyi City Song Xin Industrial Co., Ltd. filter.
