Iron and Manganese Removal filter
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.
