Iron to Fe2 + state had underground (well) water, the water has heterochromatic odor, and reduce pollution exchange capacity ion exchange resins, long after the generation of the dissolved iron, affect the heat transfer, can corrode equipment. MnO2 manganese sands and Fe2 + redox reaction, the Fe2 + into Fe3 + and generate Fe (OH) 3 precipitate, which use manganese sand filter backwash function to achieve the purpose of the removal of purification.
His natural manganese sand pool backwash time is usually 5-15 minutes. Natural manganese sand pool material surface "active membrane" structure is loose sulfur, can damage the long rinse, so filter backwash should not destroy the filter surface of the "active on the film" for the degree. No cause of the filter after a serious deterioration of water quality, groundwater iron removal filter, it should be easy to use for the iron clogging water distribution system in the form. It recommended supporting layer disposed on the tube resistance water distribution systems and grid-type or orifice plate Xu little resistance to water distribution systems
