Iron and Manganese Removal Filter

      Iron and manganese removal filter (manganese filter and iron removal filter) relies on the catalysis of manganese filter to oxidize the ferrous iron and manganese ion in water into trivalent ion, and then absorbs with natural manganese sand to reduce the iron and manganese ions in water.

     Underground water in most areas contains iron as high as 5～15mg/L and even reach 20～39 mg/L, contains manganese as high as 0.5～2.0mg/L and even exceed 2.0 mg/L. In underground water, excessive iron exists as Fe2+; therefore, newly extracted water is clear and clean but with iron smell, and the water becomes muddy as time goes by. Fe2+ can easily pollute ion exchange resin, poison resin and thus reduce exchange capability. Fe2+ pollutes RO membrane and makes it invalid. As boiler supply water, iron-containing water is subject to scale formation, affecting the heat transmission as well as tube wall corrosion. When the iron content in cooling water exceeds 0.5mg/L, iron will promote iron bacterium reproduction and the generated slime will block the pipeline as well as accelerate equipment corrosion. The high-valence manganese contained in natural manganese sand built in iron and manganese removal filter can oxidize Fe2+ in water into Fe3+, meanwhile form catalyzing “active filter membrane” on the surface of the manganese sand filter to further improve the effect of iron removal, integrating processes including oxidation, ion exchange, retaining and clarification. Reasonable design can be realized based on the water quality of the client, achieving reliable and stable effect.
  
     Aeration is required for iron and manganese removal in water to oxidize ferrous iron and manganese ion into Fe(OH)3 and MnO2. Based on the iron and manganese content in water, jet flow aeration or hollow multi-surface ball built in aeration tower may be adopted. One-level or multilevel iron and manganese filter may be used based on the iron and manganese content to meet the handling requirements. Iron content of 0.3mg/L and manganese content of 0.1 mg /l in water is in line with the national drinking water standard.

     Iron and manganese removal filter is widely applied to the water purifications in drinking water, food, paper-making, and textile, printing and dyeing, beverage, pharmaceutics, electronics and thermal power generation industries.
