Iron Removal Filter with Manganese Green Sand

Iron Removal Filter with Manganese Green Sand

Product Features:
Groundwater in addition to iron and manganese filter Our company has developed an integrated and efficient energy-saving water treatment equipment.
1, Aeration part: Without aeration tanks and aeration tower does not need to dosing chemicals and catalysts, just filling a small amount of air, which reduces operating costs.
2, The main part of the strong oxidizing reaction, separation desander, packet suspension pool filter technology in the one unit, unique structure.
3, The filter section: Since inside the filter has its own backwash device does not need to be configured. Backwash pump and backwash the pool, can reduce the area of the project, reduce the engineering investment.
4, Pressure filter backwash, high strength, rinse the filter layer evenly, do not form completely dead ends, recoil time is short, long filter cycles, to extend the service life of the filter.
5, The device can be directly water supply pipe network to the user, without with clean water tank and two pumping stations, reduce equipment investment, avoid secondary pollution.

Purposes and principles
Groundwater in addition to iron and manganese filter is mainly applied to the high concentration of iron fierce groundwater removal of iron and manganese, industrial demineralized water, demineralized water pretreatment. The device using the aeration oxide, manganese sand catalysis, adsorption, filtration in addition to iron manganese removal principle, the aeration device to the oxygen in the air to water Fe2 + and Mn2 + oxidation into water-insoluble Fe3 + and MnO2 in the combination of natural manganese sand catalysis, adsorption, filtration, removal of iron and manganese ions in water. Iron and manganese oxidation reaction in the following manner:
Iron oxide: Air: 4Fe2 + +3 O2 +6 H2O = 4Fe (OH) 3
Manganese sand MnO Mn2O7 + Fe2 + + O2 + 6 H2O = 3MnO2 +4 Fe (OH) 3
Manganese oxide: Mn2 + + O2 = MnO2
Manganese sand Mn2 + + MnO2 H2O = MnO2 MnOH2O +2 H +
Technical performance
Gas-water mixing time: 3-5min; Filter filtration speed: 10-14m / h; Backwashing strength: 16-18L / m2. S; Filter layer thickness: 1.0-1.2 m; Inlet pressure ≥ 0.06Mpa; Equipment to withstand pressure: 0.06-1.0 Mpa.
Scope: Water Fe2 + ≤ 20mg / L, Mn 2 + ≤ 10mg / L, the effluent Fe2 + ≤ 0.3mg / L, Mn 2 + ≤ 0.1mg / L.
