In addition ferromanganese device

First, the working principle of iron and manganese in addition to the working principle of the device: the use of oxidation in the water Low iron and manganese ions are oxidized to low-cost high iron and high manganese ions, and then removed by filtration through adsorption, to reduce the water content of iron and manganese purpose. Filter using fine quartz sand and manganese sand refined. The main component is manganese sand refined manganese dioxide (MnO2) which is divalent iron into trivalent iron oxide catalyst well. Refined high levels of manganese sands MnO2, which in addition to iron effect is very good, PH value greater than 5.5 groundwater containing Fe and Mn in contact with refined manganese sand can be oxidized to Fe2 + Fe3 + reaction is as follows: 2Mn2 ++ O2 + 2H2O = 2MnO2 + 4H + 4MnO2 + 3O2 = 2Mn2O7 Mn2O7 + 6Fe2 ++ 3H2O = 2MnO2 + 6Fe (OH) 3 Fe (OH) 3 precipitate is refined manganese sand filter layer after being removed. So refined manganese sand filter plays a catalytic and a double role. Manganese sand iron mechanism, in addition to relying on its own catalytic role, there in the filtration of purified manganese sand filter surface gradually form a layer of iron membrane as an active filter that can play a catalytic role. Active membrane is composed of R-type hydroxyl hydrogenated iron R-FeO (OH) is constituted, it Fe2 + ion exchange reaction, and the replacement of an equivalent amount of hydrogen ions. Fe2 + + FeO (OH) = FeO (OFe) + 2H + binds to iron (II) compounds can be carried out rapidly and the oxidation and hydrolysis reaction, again generating hydroxyl its iron oxide catalytic material to be regenerated. FeO (OFe) + O2 + H2O = 2FeO (OH) + H + new generation of iron oxyhydroxide as the active membrane material and participate in the new process of catalytic iron and iron removal process so active membrane is a autocatalytic process. BY-CTM except ferromanganese device widely used for mineral water, pure water pre-treatment in addition to the precipitation of iron and manganese, as well as pre-treatment and swimming pool in the geothermal project engineering in addition of iron and manganese and the like. If you have water need treatment, your capacity, out of water can be released to the company website http://www.027whmy.com/guestbook.asp, we will first take the initiative to communicate with you and provide a reference for you solution. Second, in addition to the structural characteristics of the composition except Fe, Mn, Fe, Mn system means the body ejector aerator intermediate pressure pump, recoil pump control system for the pump and pipe network system. The device uses the latest international technology, "active contact oxidation biofilm" of groundwater iron and manganese removal. Ferromanganese containing water after aeration, the water begins to oxidize iron, manganese sand when water flows through, is filtered, and the media due to the chemical action of iron (manganese) bacteria in the filter surface (more rust spores genus, containing Kerry's iron iron bacteria, single-celled bacteria and rust-colored coat iron bacteria) biochemical role. Interception adsorption began biochemistry melon filter layer contact oxidation reactions and physical, can greatly speed up the water iron, manganese oxide, fixing and removal. In particular, during the treatment of slightly polluted iron, manganese groundwater, the iron (manganese) bacteria not only can effectively remove Fe and Mn, while with ammonia water is a nutrient source, reproductive replaced with the participation of other bacteria, while meeting except Iron and fierce and ammonia removal effect. Treated iron content of water is less than 0.3MG / L, manganese content is less than 0.1MG / L. WB-CTM-type iron and manganese removal equipment consists of: filtration equipment, piping, KTG oxygenation equipment, water pumps, water tanks and other components. Treating body of filtration equipment. In addition ferromanganese means widely used for mineral water, pure water pre-treatment in addition to the precipitation of iron and manganese, as well as pre-treatment and swimming pool in the geothermal project engineering in addition ferromanganese, domestic water, textile water, paper water in addition to iron. Third, the operating characteristics 1. The device can be installed indoors or outdoors. 2. The device should be placed on a level concrete foundation, the foundation should be stable, even prevent subsidence. 3. recoil waste pipe, overflow pipe and vent tubes should be connected to the drain. The flowmeter should be installed in the vertical inlet pipe, the aeration device is located in the ground surface, before installation should examine it for damage or other defects. 5. Before the installation media, the device should be built in water 1 / 3-1 / 2, and then press the particle size grading requirements hierarchical tiling, filter loading, it should be cleaned, the water from the bottom up, until the water clarification. 6. In addition to the iron equipment is running, first turn off the water valve and water valve anti rushed to start into the water pump, and immediately open the inlet valve and outlet valve regulating water flow to keep out of the water balance. 7. Front backwash, first close the inlet valve and the valve, then stop the pump. If you have water need treatment, your capacity, out of water can be released to the company website http://www.027whmy.com/guestbook.asp, we will first take the initiative to communicate with you and provide a reference for you solution.
