Iron has been in the state of Fe2 + in underground (well) water. Its water has a different color and odor, which contaminates the ion exchange resin and reduces the exchange capacity. After a long time, iron scale is generated, which affects heat transfer and can corrode equipment. The MnO2 in manganese sand undergoes a redox reaction with Fe2 +, which changes Fe2 + to Fe3 + and generates Fe (OH) 3 precipitation, so that the backwash function of the manganese sand filter is used to achieve the purpose of removal and purification.

Advantage of Manganese Sand

  • Strongest interception capacity
  • Largest oxidation catalysis
  • Smallest backwash bleed rate

Application of Manganese Sand

  • Mn remove
  • Iron removal
  • Ground water treatment
  • Drinking water purify
  • Well water purification
